what are good ways to implement search and search results using ajax?

- by Amr ElGarhy

i have some text box in a page and in the same page there will be a table 'grid' like for holding the search result. When the user start editing and of the textbox above, the search must start by sending all textboxs values to the server 'ajax', and get back with the results to fill the below grid. Notes: This grid should support paging, sorting by clicking on headers and it will contains some controls beside the results such as checkboxs for boolean values and links for opening details in another page. I know many ways to do this some of them are: 1- updatepanel around all of these controls and thats it "fast dirty solution" 2- send the search criteria using ajax request using JQuery post function for example and get back the JSON result, and using a template will draw the grid "clean but will take time to finish and will be harder to edit later". 3- .... My question is: What do you think will be the best choice to implement this scenario? because i face this scenario too much, and want to know which implementation will be better regarding performance, optimization, and time to finish. I just want to know your thoughts about this issue.

Save many-to-one relationship from JSON into Core Data

- by Snow Crash

I'm wanting to save a Many-to-one relationship parsed from JSON into Core Data. The code that parses the JSON and does the insert into Core Data looks like this: for (NSDictionary *thisRecipe in recipes) { Recipe *recipe = [NSEntityDescription insertNewObjectForEntityForName:@"Recipe" inManagedObjectContext:insertionContext]; recipe.title = [thisRecipe objectForKey:@"Title"]; NSDictionary *ingredientsForRecipe = [thisRecipe objectForKey:@"Ingredients"]; NSArray *ingredientsArray = [ingredientsForRecipe objectForKey:@"Results"]; for (NSDictionary *thisIngredient in ingredientsArray) { Ingredient *ingredient = [NSEntityDescription insertNewObjectForEntityForName:@"Ingredient" inManagedObjectContext:insertionContext]; ingredient.name = [thisIngredient objectForKey:@"Name"]; } } NSSet *ingredientsSet = [NSSet ingredientsArray]; [recipe setIngredients:ingredientsSet]; Notes: "setIngredients" is a Core Data generated accessor method. There is a many-to-one relationship between Ingredients and Recipe However, when I run this I get the following error: NSCFDictionary managedObjectContext]: unrecognized selector sent to instance If I remove the last line (i.e. [recipe setIngredients:ingredientsSet];) then, taking a peek at the SQLite database, I see the Recipe and Ingredients have been stored but no relationship has been created between Recipe and Ingredients Any suggestions as to how to ensure the relationship is stored correctly?

UIWebView loading/randering error after resize

- by user1343869

I have a screen with 2 UIWebView. The user can drag the views left and right to make the right and left view bigger (respectively) and the other one smaller (like UISplitView but customized and self made). I'm loading .html pages from strings and local .css files. After resizing the UIWebView If I load a new page there will be a black or white stripe on the right side of the UIWebView. This stripe is part of the web view (not a space between the views), and if I scroll the webView up and then down, the stripe will vanish and the page will be presented correctly. This issue occurs only in iOS 6 and only on the device (on the simulator it doesn't occur). Some notes: - The .css file contains elements with fixed position. Changing to absolute position didn't solve the problem but changed it: the black stripre occured during the drag. - As slower the drag is, the stripe will be bigger. - After resize the page is presented correctly, only when I load a new page the stripe is shown. - The time between resizing the web view and loading a page doesn't matter, it can be straight away or after couple of minutes. Now, as a workaround I create a new UIWebView and copy the old properties to the new. But than I need to reload the presented page which make a white blink... Any idea why does it happens, and how to fix it?

CodeGolf: Find the Unique Paths

- by st0le

Here's a pretty simple idea, in this pastebin I've posted some pair of numbers. These represent Nodes of a directed graph. The input to stdin will be of the form, (they'll be numbers, i'll be using an example here) c d q r a b b c d e p q so x y means x is connected to y (not viceversa) There are 2 paths in that example. a->b->c->d->e and p->q->r. You need to print all the unique paths from that graph The output should be of the format a->b->c->d->e p->q->r Notes You can assume the numbers are chosen such that one path doesn't intersect the other (one node belongs to one path) The pairs are in random order. They are more than 1 paths, they can be of different lengths. All numbers are less than 1000. If you need more details, please leave a comment. I'll amend as required. Shameless-Plug For those who enjoy Codegolf, please Commit at Area51 for its very own site:) (for those who don't enjoy it, please support it as well, so we'll stay out of your way...)

retrieving and restoring textview information from sharedpreferences

- by user1742524

I have an activity that allows user to enter notes and store them in dynamically created textviews. However, when the use leaves the activity and returns, all the created textviews disappear. How can i store store or retrieve all of these created textviews, whenever i return to the activity? Also, i think that my sharedpreferences will be overwriting each time a new textview is added. Any suggestions? public class DocNoteActivity extends Activity { private LinearLayout nLayout; private EditText etDocNote; private Button btnAdd1; public static final String PREFS_NAME = "MyPrefsFile"; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.adddocnote); etDocNote = (EditText) findViewById(R.id.editDocNote); btnAdd1 = (Button) findViewById(R.id.btnAdd1); nLayout = (LinearLayout) findViewById(R.id.linearLayout); TextView tvNote = new TextView(this); tvNote.setText(""); btnAdd1.setOnClickListener(onClick()); } private OnClickListener onClick() { // TODO Auto-generated method stub return new OnClickListener(){ public void onClick(View v) { // TODO Auto-generated method stub String newDocNote = etDocNote.getText().toString(); nLayout.addView(createNewTextView(newDocNote)); getSharedPreferences("myprefs", 0).edit().putString("etDocNote", newDocNote).commit(); } }; } private TextView createNewTextView(String newText) { // TODO Auto-generated method stub LayoutParams lparams = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); TextView tvNote = new TextView(this); tvNote.setLayoutParams(lparams); tvNote.setText(newText); return tvNote; } }

OCR anything with OneNote 2007 and 2010

- by Matthew Guay

Quality OCR software can often be very expensive, but you may have one already installed on your computer that you didn’t know about. Here’s how you can use OneNote to OCR anything on your computer. OneNote is one of the overlooked gems in recent versions of Microsoft Office. OneNote makes it simple to take notes and keep track of everything with integrated search, and offers more features than its popular competitor Evernote. One way it is better is its high quality optical character recognition (OCR) engine. One of Evernote’s most popular features is that you can search for anything, including text in an image, and you can easily find it. OneNote takes this further, and instantly OCRs any text in images you add. Then, you can use this text easily and copy it from the image. Let’s see how this works and how you can use OneNote as the ultimate OCR. Please Note: This feature is available in OneNote 2007 and 2010. OneNote 2007 is included with Office 2007 Home and Student, Enterprise, and Ultimate, while OneNote 2010 is included with all edition of Office 2010 except for Starter edition. OCR anything First, let’s add something to OCR into OneNote. There are many different ways you can add items to OCR into OneNote. Open a blank page or one you want to insert something into, and then follow these steps to add what you want into OneNote. Picture Simply drag-and-drop a picture with text into a notebook… You can insert a picture directly from OneNote as well. In OneNote 2010, select the Insert tab, and then choose Picture. In OneNote 2007, select the Insert menu, select Picture, and then choose From File. Screen Clipping There are many times we’d like to copy text from something we see onscreen, but there is no direct way to copy text from that thing. For instance, you cannot copy text from the title-bar of a window, or from a flash-based online presentation. For these cases, the Screen Clipping option is very useful. To add a clip of anything onscreen in OneNote 2010, select the Insert tab in the ribbon and click Screen Clipping. In OneNote 2007, either click the Clip button on the toolbar or select the Insert menu and choose Screen Clipping. Alternately, you can take a screen clipping by pressing the windows key + S. When you click Screen Clipping, OneNote will minimize, your desktop will fade lighter, and your mouse pointer will change to a plus sign. Now, click and drag over anything you want to add to OneNote. Here we’re selecting the title of this article. The section you selected will now show up in your OneNote notebook, complete with the date and time the clip was made. Insert a file You’re not limited to pictures; OneNote can even OCR anything in most files on your computer. You can add files directly in OneNote 2010 by selecting File Printout in the Insert tab. In OneNote 2007, select the Insert menu and choose Files as Printout. Choose the file you want to add to OneNote in the dialog. Select Insert, and OneNote will pause momentarily as it processes the file. Now your file will show up in OneNote as a printout with a link to the original file above it. You can also send any file directly to OneNote via the OneNote virtual printer. If you have a file open, such as a PDF, that you’d like to OCR, simply open the print dialog in that program and select the “Send to OneNote” printer. Or, if you have a scanner, you can scan documents directly into OneNote by clicking Scanner Printout in the Insert tab in OneNote 2010. In OneNote 2003, to add a scanned document select the Insert menu, select Picture, and then choose From Scanner or Camera. OCR the image, file, or screenshot you put in OneNote Now that you’ve got your stuff into OneNote, let’s put it to work. OneNote automatically did an OCR scan on anything you inserted into OneNote. You can check to make sure by right-clicking on any picture, screenshot, or file you inserted. Select “Make Text in Image Searchable” and then make sure the correct language is selected. Now, you can copy text from the Picture. Simply right-click on the picture, and select “Copy Text from Picture”. And here’s the text that OneNote found in this picture: OCR anything with OneNote 2007 and 2010 - Windows Live Writer Not bad, huh? Now you can paste the text from the picture into a document or anywhere you need to use the text. If you are instead copying text from a printout, it may give you the option to copy text from this page or all pages of the printout. This works the exact same in OneNote 2007. In OneNote 2010, you can also edit the text OneNote has saved in the image from the OCR. This way, if OneNote read something incorrectly you can change it so you can still find it when you use search in OneNote. Additionally, you can copy only a specific portion of the text from the edit box, so it can be useful just for general copying as well. To do this, right-click on the item and select “Edit Alt Text”. Here is the window to edit alternate text. If you want to copy only a portion of the text, simply select it and press Ctrl+C to copy that portion. Searching OneNote’s OCR engine is very useful for finding specific pictures you have saved in OneNote. Simply enter your search query in the search box on top right, and OneNote will automatically find all instances of that term in all of your notebooks. Notice how it highlights the search term even in the image! This works the same in OneNote 2007. Notice how it highlighted “How-to” in a shot of the header image in our favorite website. In Windows Vista and 7, you can even search for things OneNote OCRed from the Start Menu search. Here the start menu search found the words “Windows Live Writer” in our OCR Test notebook in OneNote where we inserted the screen clip above. Conclusion OneNote is a very useful OCR tool, and can help you capture text from just about anything. Plus, since you can easily search everything you have stored in OneNote, you can quickly find anything you insert anytime. OneNote is one of the least-used Office tools, but we have found it very useful and hope you do too.

SharePoint - Summing Calculated Columns By Groups (DVWP)

- by Mark Rackley

I had a problem… okay.. okay.. so I have many problems… but let’s focus on one in particular or this blog post would never end… okay? Thank you…. So, I had an electronic timesheet where users entered hours for each day of the week. It also had a “Week Total” column which was a calculated column of the sum. The calculated column looked like this: Pretty easy.. nothing spectacular. So, what’s the problem? WELL……………….. There is a row in the timesheet for each task a person worked on in a given week. So, if you worked on 4 tasks, you would have 4 rows of data, and 4 week totals for that week: This is all fine and dandy, but I want to know what the total was for the entire week. Yes.. I realize the answer is 24 from my example… I mean, I know how to add! I just want SharePoint to display it for me for the executives (we all know, they have math problems). You may be thinking, hey genius (in a sarcastic tone of course), why don’t you just go to the view and total on the “Week Total” field. What a brilliant idea! Why didn’t I think of that… let’s go to the view and do just that…. Ohhhhhh… you can’t total on a Calculated Column.. it’s not even an option… Yeah… I had the same moment. So, what do you do? Well… what do you think I did? 1) Googled “SharePoint total calculated column” 2) Said it couldn’t be done 3) Took a nap 4) Asked the question on twitter? The correct answer of course is number 4… followed by number 3… although I may have told my boss number 2 so that I look more brilliant than I am? It’s safe to say I did NOT try to find the solution on my own doing step 1… that would be just WAY to easy… So, anyway, I posted the question on Twitter and it turns out several people had suggestions from using jQuery to using DVWPs. I tend to be a big fan of the DVWP except for the disgusting process of deploying them to another farm.. ugh… just shoot me…. so, that is the solution I went with. Laura Rogers (@WonderLaura) has a super duper easy to follow video on the subject over at EndUserSharePoint.com: SharePoint: Displaying Calculated Column SUMS in a View (Screencast) Laura’s video was very easy to follow and was ALMOST exactly what I needed. She does a great job walking you through every step of summing up a calculated field which was PART of my problem. The other part was my list is grouped by date! So, I wanted to see for a given week, the summed “Week Total” of hours. Laura got me on the right track with her video and I dug a little deeper into the DVWP to accomplish my task. So, here are the steps you follow: 1. Click on the "chevron” (I didn’t know it was actually called that until I heard Laura say it).. I always call it the “little-button-in-the-top-right-corner-with-the-greater-than-sign”.. but “chevron” is much shorter. So, click on the chevron, click on “Sort and Group”. The Add the field you want to group by, in my example it is the “Monday Date” of the timesheet entry. Make sure to check the check boxes for “Show Group Header” AND “Show Group Footer”. Click “OK”. The view now shows the count of each grouped set of data: Interesting, this looks very similar to Laura’s video… right? So, let’s take a look at the code for the Count: Count : <xsl:value-of select="count($nodeset)" /> Wow, also very similar… except in Laura’s video it looks like: Count : <xsl:value-of select="count($Rows)" /> So.. the only difference is that instead of $Rows we have $nodeset. It turns out the $nodeset will go through each Row in the group just like $Rows goes through each row in the entire view. So, using the exact same logic as in Laura’s blog except replacing $Rows with $nodeset we get the functionality of being able to sum up the values for a group. So, I want to replace “Count: #” with the total hours, this is done using the following changes to the above code: Week Total : <xsl:value-of select="sum($nodeset/@Monday)+sum($nodeset/@Tuesday) +sum($nodeset/@Wednesday)+sum($nodeset/@Thursday)+sum($nodeset/@Friday) +sum($nodeset/@Saturday)+sum($nodeset/@Sunday)" /> Our final output has the summed hours for each group! So… long story short… follow Laura’s blog, then group your list, then replace “$Rows” with “$nodeset”. One caveat, this will not work if you group by a person field. For some reason the person field does not go through each row in the group. I haven’t dug into this much yet. Maybe if I find some time… whatever that is… Anyway, Laura did all the work, I just took it one small step forward… as always, feel free to leave any additional insights you may have. We’re all learning here!

Working with Silverlight DataGrid RowDetailsTemplate

- by mohanbrij

In this post I am going to show how we can use the Silverlight DataGrid RowDetails Template, Before I start I assume that you know basics of Silverlight and also know how you create a Silverlight Projects. I have started with the Silverlight Application, and kept all the default options before I created a Silverlight Project. After this I added a Silverlight DataGrid control to my MainForm.xaml page, using the DragDrop feature of Visual Studio IDE, this will help me to add the default namespace and references automatically. Just to give you a quick look of what exactly I am going to do, I will show you in the screen below my final target, before I start explaining rest of my codes. Before I start with the real code, first I have to do some ground work, as I am not getting the data from the DB, so I am creating a class where I will populate the dummy data. EmployeeData.cs public class EmployeeData { public string FirstName { get; set; } public string LastName { get; set; } public string Address { get; set; } public string City { get; set; } public string State { get; set; } public string Country { get; set; } public EmployeeData() { } public List<EmployeeData> GetEmployeeData() { List<EmployeeData> employees = new List<EmployeeData>(); employees.Add ( new EmployeeData { Address = "#407, PH1, Foyer Appartment", City = "Bangalore", Country = "India", FirstName = "Brij", LastName = "Mohan", State = "Karnataka" }); employees.Add ( new EmployeeData { Address = "#332, Dayal Niketan", City = "Jamshedpur", Country = "India", FirstName = "Arun", LastName = "Dayal", State = "Jharkhand" }); employees.Add ( new EmployeeData { Address = "#77, MSR Nagar", City = "Bangalore", Country = "India", FirstName = "Sunita", LastName = "Mohan", State = "Karnataka" }); return employees; } } The above class will give me some sample data, I think this will be good enough to start with the actual code. now I am giving below the XAML code from my MainForm.xaml First I will put the Silverlight DataGrid, <data:DataGrid x:Name="gridEmployee" CanUserReorderColumns="False" CanUserSortColumns="False" RowDetailsVisibilityMode="VisibleWhenSelected" HorizontalAlignment="Center" ScrollViewer.VerticalScrollBarVisibility="Auto" Height="200" AutoGenerateColumns="False" Width="350" VerticalAlignment="Center"> Here, the most important property which I am going to set is RowDetailsVisibilityMode="VisibleWhenSelected" This will display the RowDetails only when we select the desired Row. Other option we have in this is Collapsed and Visible. Which will either make the row details always Visible or Always Collapsed. but to get the real effect I have selected VisibleWhenSelected. Now I am going to put the rest of my XAML code. <data:DataGrid.Columns>  <data:DataGridTextColumn Width="150" Header="First Name" Binding="{Binding FirstName}"/>   <data:DataGridTextColumn Width="150" Header="Last Name" Binding="{Binding LastName}"/>  </data:DataGrid.Columns> <data:DataGrid.RowDetailsTemplate>  <DataTemplate> <Border BorderBrush="Black" BorderThickness="1" Background="White"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="0.2*" /> <ColumnDefinition Width="0.8*" /> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition /> <RowDefinition /> <RowDefinition /> <RowDefinition /> </Grid.RowDefinitions>  <TextBlock Text="Address : " Grid.Column="0" Grid.Row="0" /> <TextBlock Text="{Binding Address}" Grid.Column="1" Grid.Row="0" /> <TextBlock Text="City : " Grid.Column="0" Grid.Row="1" /> <TextBlock Text="{Binding City}" Grid.Column="1" Grid.Row="1" /> <TextBlock Text="State : " Grid.Column="0" Grid.Row="2" /> <TextBlock Text="{Binding State}" Grid.Column="1" Grid.Row="2" /> <TextBlock Text="Country : " Grid.Column="0" Grid.Row="3" /> <TextBlock Text="{Binding Country}" Grid.Column="1" Grid.Row="3" /> </Grid> </Border> </DataTemplate>  </data:DataGrid.RowDetailsTemplate> In the code above, first I am declaring the simple dataGridTextColumn for FirstName and LastName, and after this I am creating the RowDetailTemplate, where we are just putting the code what we usually do to design the Grid. I mean nothing very much RowDetailTemplate Specific, most of the code which you will see inside the RowDetailsTemplate is plain and simple, where I am binding rest of the Address Column. And that,s it. Once we will bind the DataGrid, you are ready to go. In the code below from MainForm.xaml.cs, I am just binding the DataGrid public partial class MainPage : UserControl { public MainPage() { InitializeComponent(); BindControls(); } private void BindControls() { EmployeeData employees = new EmployeeData(); gridEmployee.ItemsSource = employees.GetEmployeeData(); } } Once you will run, you can see the output I have given in the screenshot above. In this example I have just shown the very basic example, now it up to your creativity and requirement, you can put some other controls like checkbox, Images, even other DataGrid, etc inside this RowDetailsTemplate column. I am attaching my sample source code with this post. I have used Silverlight 3 and Visual Studio 2008, but this is fully compatible with you Silverlight 4 and Visual Studio 2010. you may just need to Upgrade the attached Sample. You can download from here.

Android - creating a custom preferences activity screen

- by Bill Osuch

Android applications can maintain their own internal preferences (and allow them to be modified by users) with very little coding. In fact, you don't even need to write an code to explicitly save these preferences, it's all handled automatically! Create a new Android project, with an intial activity title Main. Create two more activities: ShowPrefs, which extends Activity Set Prefs, which extends PreferenceActivity Add these two to your AndroidManifest.xml file: <activity android:name=".SetPrefs"></activity> <activity android:name=".ShowPrefs"></activity> Now we'll work on fleshing out each activity. First, open up the main.xml layout file and add a couple of buttons to it: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <Button android:text="Edit Preferences" android:id="@+id/prefButton" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal"/> <Button android:text="Show Preferences" android:id="@+id/showButton" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal"/> </LinearLayout> Next, create a couple button listeners in Main.java to handle the clicks and start the other activities: Button editPrefs = (Button) findViewById(R.id.prefButton); editPrefs.setOnClickListener(new View.OnClickListener() { public void onClick(View view) { Intent myIntent = new Intent(view.getContext(), SetPrefs.class); startActivityForResult(myIntent, 0); } }); Button showPrefs = (Button) findViewById(R.id.showButton); showPrefs.setOnClickListener(new View.OnClickListener() { public void onClick(View view) { Intent myIntent = new Intent(view.getContext(), ShowPrefs.class); startActivityForResult(myIntent, 0); } }); Now, we'll create the actual preferences layout. You'll need to create a file called preferences.xml inside res/xml, and you'll likely have to create the xml directory as well. Add the following xml: <?xml version="1.0" encoding="utf-8"?> <PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"> </PreferenceScreen> First we'll add a category, which is just a way to group similar preferences... sort of a horizontal bar. Add this inside the PreferenceScreen tags: <PreferenceCategory android:title="First Category"> </PreferenceCategory> Now add a Checkbox and an Edittext box (inside the PreferenceCategory tags): <CheckBoxPreference android:key="checkboxPref" android:title="Checkbox Preference" android:summary="This preference can be true or false" android:defaultValue="false"/> <EditTextPreference android:key="editTextPref" android:title="EditText Preference" android:summary="This allows you to enter a string" android:defaultValue="Nothing"/> The key is how you will refer to the preference in code, the title is the large text that will be displayed, and the summary is the smaller text (this will make sense when you see it). Let's say we've got a second group of preferences that apply to a different part of the app. Add a new category just below the first one: <PreferenceCategory android:title="Second Category"> </PreferenceCategory> In there we'll a list with radio buttons, so add: <ListPreference android:key="listPref" android:title="List Preference" android:summary="This preference lets you select an item in a array" android:entries="@array/listArray" android:entryValues="@array/listValues" /> When complete, your full xml file should look like this: <?xml version="1.0" encoding="utf-8"?> <PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"> <PreferenceCategory android:title="First Category"> <CheckBoxPreference android:key="checkboxPref" android:title="Checkbox Preference" android:summary="This preference can be true or false" android:defaultValue="false"/> <EditTextPreference android:key="editTextPref" android:title="EditText Preference" android:summary="This allows you to enter a string" android:defaultValue="Nothing"/> </PreferenceCategory> <PreferenceCategory android:title="Second Category"> <ListPreference android:key="listPref" android:title="List Preference" android:summary="This preference lets you select an item in a array" android:entries="@array/listArray" android:entryValues="@array/listValues" /> </PreferenceCategory> </PreferenceScreen> However, when you try to save it, you'll get an error because you're missing your array definition. To fix this, add a file called arrays.xml in res/values, and paste in the following: <?xml version="1.0" encoding="utf-8"?> <resources> <string-array name="listArray"> <item>Value 1</item> <item>Value 2</item> <item>Value 3</item> </string-array> <string-array name="listValues"> <item>1</item> <item>2</item> <item>3</item> </string-array> </resources> Finally (for the preferences screen at least...) add the code that will display the preferences layout to the SetPrefs.java file: @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); addPreferencesFromResource(R.xml.preferences); } OK, so now we've got an activity that will set preferences, and save them without the need to write custom save code. Let's throw together an activity to work with the saved preferences. Create a new layout called showpreferences.xml and give it three Textviews: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TextView android:id="@+id/textview1" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="textview1"/> <TextView android:id="@+id/textview2" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="textview2"/> <TextView android:id="@+id/textview3" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="textview3"/> </LinearLayout> Open up the ShowPrefs.java file and have it use that layout: setContentView(R.layout.showpreferences); Then add the following code to load the DefaultSharedPreferences and display them: SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this); TextView text1 = (TextView)findViewById(R.id.textview1); TextView text2 = (TextView)findViewById(R.id.textview2); TextView text3 = (TextView)findViewById(R.id.textview3); text1.setText(new Boolean(prefs.getBoolean("checkboxPref", false)).toString()); text2.setText(prefs.getString("editTextPref", "<unset>"));; text3.setText(prefs.getString("listPref", "<unset>")); Fire up the application in the emulator and click the Edit Preferences button. Set various things, click the back button, then the Edit Preferences button again. Notice that your choices have been saved. Now click the Show Preferences button, and you should see the results of what you set: There are two more preference types that I did not include here: RingtonePreference - shows a radioGroup that lists your ringtones PreferenceScreen - allows you to embed a second preference screen inside the first - it opens up a new set of preferences when clicked

Creating an AJAX Accordion Menu

- by jaullo

Introduction Ajax is a powerful addition to asp.net that provides new functionality in a simple and agile way This post is dedicated to creating a menu with ajax accordion type. About the Control The basic idea of this control, is to provide a serie of panels and show and hide information inside these panels. The use is very simple, we have to set each panel inside accordion control and give to each panel a Header and of course, we have to set the content of each panel. To use accordion control, u need the ajax control toolkit. know the basic propertyes of accordion control: Before start developing an accordion control, we have to know the basic properties for this control Other accordion propertyes FramesPerSecond - Number of frames per second used in the transition animations RequireOpenedPane - Prevent closing the currently opened pane when its header is clicked (which ensures one pane is always open). The default value is true. SuppressHeaderPostbacks - Prevent the client-side click handlers of elements inside a header from firing (this is especially useful when you want to include hyperlinks in your headers for accessibility) DataSource - The data source to use. DataBind() must be called. DataSourceID - The ID of the data source to use. DataMember - The member to bind to when using a DataSourceID AJAX Accordion Control Extender DataSource The Accordion Control extender of AJAX Control toolkit can also be used as DataBound control. You can bind the data retrieved from the database to the Accordion control. Accordion Control consists of properties such as DataSource and DataSourceID (we can se it above) that can be used to bind the data. HeaderTemplate can used to display the header or title for the pane generated by the Accordion control, a click on which will open or close the ContentTemplate generated by binding the data with Accordion extender. When DataSource is passed to the Accordion control, also use the DataBind method to bind the data. The Accordion control bound with data auto generates the expand/collapse panes along with their headers. This code represents the basic steps to bind the Accordion to a Datasource Collapse Public Sub getCategories() Dim sqlConn As New SqlConnection(conString) sqlConn.Open() Dim sqlSelect As New SqlCommand("SELECT * FROM Categories", sqlConn) sqlSelect.CommandType = System.Data.CommandType.Text Dim sqlAdapter As New SqlDataAdapter(sqlSelect) Dim myDataset As New DataSet() sqlAdapter.Fill(myDataset) sqlConn.Close() Accordion1.DataSource = myDataset.Tables(0).DefaultView Accordion1.DataBind()End Sub Protected Sub Accordion1_ItemDataBound(sender As Object, _ e As AjaxControlToolkit.AccordionItemEventArgs) If e.ItemType = AjaxControlToolkit.AccordionItemType.Content Then Dim sqlConn As New SqlConnection(conString) sqlConn.Open() Dim sqlSelect As New SqlCommand("SELECT productName " & _ "FROM Products where categoryID = '" + _ DirectCast(e.AccordionItem.FindControl("txt_categoryID"),_ HiddenField).Value + "'", sqlConn) sqlSelect.CommandType = System.Data.CommandType.Text Dim sqlAdapter As New SqlDataAdapter(sqlSelect) Dim myDataset As New DataSet() sqlAdapter.Fill(myDataset) sqlConn.Close() Dim grd As New GridView() grd = DirectCast(e.AccordionItem.FindControl("GridView1"), GridView) grd.DataSource = myDataset grd.DataBind() End If End Sub In the above code, we made two things, first, we made a sql select to database to retrieve all data from categories table, this data will be used to set the header and columns of the accordion. Collapse <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> <ajaxToolkit:Accordion ID="Accordion1" runat="server" TransitionDuration="100" FramesPerSecond="200" FadeTransitions="true" RequireOpenedPane="false" OnItemDataBound="Accordion1_ItemDataBound" ContentCssClass="acc-content" HeaderCssClass="acc-header" HeaderSelectedCssClass="acc-selected"> <HeaderTemplate> <%#DataBinder.Eval(Container.DataItem,"categoryName") %> </HeaderTemplate> <ContentTemplate> <asp:HiddenField ID="txt_categoryID" runat="server" Value='<%#DataBinder.Eval(Container.DataItem,"categoryID") %>' /> <asp:GridView ID="GridView1" runat="server" RowStyle-BackColor="#ededed" RowStyle-HorizontalAlign="Left" AutoGenerateColumns="false" GridLines="None" CellPadding="2" CellSpacing="2" Width="300px"> <Columns> <asp:TemplateField HeaderStyle-HorizontalAlign="Left" HeaderText="Product Name" HeaderStyle-BackColor="#d1d1d1" HeaderStyle-ForeColor="#777777"> <ItemTemplate> <%#DataBinder.Eval(Container.DataItem,"productName") %> </ItemTemplate> </asp:TemplateField> </Columns> </asp:GridView> </ContentTemplate> </ajaxToolkit:Accordion> Here, we use <%#DataBinder.Eval(Container.DataItem,"categoryName") %> to bind accordion header with categoryName, so we made on header for each element found on database. Creating a basic accordion control As we know, to use any of the ajax components, there must be a registered ScriptManager on our site, which will be responsible for managing our controls. So the first thing we will do is create our script manager. Collapse <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager> Then we define our accordion element and establish some basic properties: Collapse <cc1:Accordion ID="AccordionCtrl" runat="server" SelectedIndex="0" HeaderCssClass="accordionHeader" ContentCssClass="accordionContent" AutoSize="None" FadeTransitions="true" TransitionDuration="250" FramesPerSecond="40" For our work we must declare PANES accordion inside it, these breads will be responsible for contain information, links or information that we want to show. Collapse <Panes> <cc1:AccordionPane ID="AccordionPane0" runat="server"> <Header>Matenimiento</Header> <Content> <li><a href="mypagina.aspx">My página de prueba</a></li> </Content> </cc1:AccordionPane> To end this work, we have to close all panels and our accordion Collapse </Panes> </cc1:Accordion> Finally complete our example should look like: Collapse <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager> <cc1:Accordion ID="AccordionCtrl" runat="server" SelectedIndex="0" HeaderCssClass="accordionHeader" ContentCssClass="accordionContent" AutoSize="None" FadeTransitions="true" TransitionDuration="250" FramesPerSecond="40"> <Panes> <cc1:AccordionPane ID="AccordionPane0" runat="server"> <Header>Matenimiento</Header> <Content> <li><a href="mypagina.aspx">My página de prueba</a></li> </Content> </cc1:AccordionPane> </Panes> </cc1:Accordion>

Conversation as User Assistance

- by ultan o'broin

Applications User Experience members (Erika Web, Laurie Pattison, and I) attended the User Assistance Europe Conference in Stockholm, Sweden. We were impressed with the thought leadership and practical application of ideas in Anne Gentle's keynote address "Social Web Strategies for Documentation". After the conference, we spoke with Anne to explore the ideas further. Anne Gentle (left) with Applications User Experience Senior Director Laurie Pattison In Anne's book called Conversation and Community: The Social Web for Documentation, she explains how user assistance is undergoing a seismic shift. The direction is away from the old print manuals and online help concept towards a web-based, user community-driven solution using social media tools. User experience professionals now have a vast range of such tools to start and nurture this "conversation": blogs, wikis, forums, social networking sites, microblogging systems, image and video sharing sites, virtual worlds, podcasts, instant messaging, mashups, and so on. That user communities are a rich source of user assistance is not a surprise, but the extent of available assistance is. For example, we know from the Consortium for Service Innovation that there has been an 'explosion' of user-generated content on the web. User-initiated community conversations provide as much as 30 times the number of official help desk solutions for consortium members! The growing reliance on user community solutions is clearly a user experience issue. Anne says that user assistance as conversation "means getting closer to users and helping them perform well. User-centered design has been touted as one of the most important ideas developed in the last 20 years of workplace writing. Now writers can take the idea of user-centered design a step further by starting conversations with users and enabling user assistance in interactions." Some of Anne's favorite examples of this paradigm shift from the world of traditional documentation to community conversation include: Writer Bob Bringhurst's blog about Adobe InDesign and InCopy products and Adobe's community help The Microsoft Development Network Community Center ·The former Sun (now Oracle) OpenDS wiki, NetBeans Ruby and other community approaches to engage diverse audiences using screencasts, wikis, and blogs. Cisco's customer support wiki, EMC's community, as well as Symantec and Intuit's approaches The efforts of Ubuntu, Mozilla, and the FLOSS community generally Adobe Writer Bob Bringhurst's Blog Oracle is not without a user community conversation too. Besides the community discussions and blogs around documentation offerings, we have the My Oracle Support Community forums, Oracle Technology Network (OTN) communities, wiki, blogs, and so on. We have the great work done by our user groups and customer councils. Employees like David Haimes reach out, and enthusiastic non-employee gurus like Chet Justice (OracleNerd), Floyd Teter and Eddie Awad provide great "how-to" information too. But what does this paradigm shift mean for existing technical writers as users turn away from the traditional printable PDF manual deliverables? We asked Anne after the conference. The writer role becomes one of conversation initiator or enabler. The role evolves, along with the process, as the users define their concept of user assistance and terms of engagement with the product instead of having it pre-determined. It is largely a case now of "inventing the job while you're doing it, instead of being hired for it" Anne said. There is less emphasis on formal titles. Anne mentions that her own title "Content Stacker" at OpenStack; others use titles such as "Content Curator" or "Community Lead". However, the role remains one essentially about communications, "but of a new type--interacting with users, moderating, curating content, instead of sitting down to write a manual from start to finish." Clearly then, this role is open to more than professional technical writers. Product managers who write blogs, developers who moderate forums, support professionals who update wikis, rock star programmers with a penchant for YouTube are ideal. Anyone with the product knowledge, empathy for the user, and flair for relationships on the social web can join in. Some even perform these roles already but do not realize it. Anne feels the technical communicator space will move from hiring new community conversation professionals (who are already active in the space through blogging, tweets, wikis, and so on) to retraining some existing writers over time. Our own research reveals that the established proponents of community user assistance even set employee performance objectives for internal content curators about the amount of community content delivered by people outside the organization! To take advantage of the conversations on the web as user assistance, enterprises must first establish where on the spectrum their community lies. "What is the line between community willingness to contribute and the enterprise objectives?" Anne asked. "The relationship with users must be managed and also measured." Anne believes that the process can start with a "just do it" approach. Begin by reaching out to existing user groups, individual bloggers and tweeters, forum posters, early adopter program participants, conference attendees, customer advisory board members, and so on. Use analytical tools to measure the level of conversation about your products and services to show a return on investment (ROI), winning management support. Anne emphasized that success with the community model is dependent on lowering the technical and motivational barriers so that users can readily contribute to the conversation. Simple tools must be provided, and guidelines, if any, must be straightforward but not mandatory. The conversational approach is one where traditional style and branding guides do not necessarily apply. Tools and infrastructure help users to create content easily, to search and find the information online, read it, rate it, translate it, and participate further in the content's evolution. Recognizing contributors by using ratings on forums, giving out Twitter kudos, conference invitations, visits to headquarters, free products, preview releases, and so on, also encourages the adoption of the conversation model. The move to conversation as user assistance is not free, but there is a business ROI. The conversational model means that customer service is enhanced, as user experience moves from a functional to a valued, emotional level. Studies show a positive correlation between loyalty and financial performance (Consortium for Service Innovation, 2010), and as customer experience and loyalty become key differentiators, user experience professionals cannot explore the model's possibilities. The digital universe (measured at 1.2 million petabytes in 2010) is doubling every 12 to 18 months, and 70 percent of that universe consists of user-generated content (IDC, 2010). Conversation as user assistance cannot be ignored but must be embraced. It is a time to manage for abundance, not scarcity. Besides, the conversation approach certainly sounds more interesting, rewarding, and fun than the traditional model! I would like to thank Anne for her time and thoughts, and recommend that all user assistance professionals read her book. You can follow Anne on Twitter at: http://www.twitter.com/annegentle.

Reporting Services - It's a Wrap!

- by smisner

If you have any experience at all with Reporting Services, you have probably developed a report using the matrix data region. It's handy when you want to generate columns dynamically based on data. If users view a matrix report online, they can scroll horizontally to view all columns and all is well. But if they want to print the report, the experience is completely different and you'll have to decide how you want to handle dynamic columns. By default, when a user prints a matrix report for which the number of columns exceeds the width of the page, Reporting Services determines how many columns can fit on the page and renders one or more separate pages for the additional columns. In this post, I'll explain two techniques for managing dynamic columns. First, I'll show how to use the RepeatRowHeaders property to make it easier to read a report when columns span multiple pages, and then I'll show you how to "wrap" columns so that you can avoid the horizontal page break. Included with this post are the sample RDLs for download. First, let's look at the default behavior of a matrix. A matrix that has too many columns for one printed page (or output to page-based renderer like PDF or Word) will be rendered such that the first page with the row group headers and the inital set of columns, as shown in Figure 1. The second page continues by rendering the next set of columns that can fit on the page, as shown in Figure 2.This pattern continues until all columns are rendered. The problem with the default behavior is that you've lost the context of employee and sales order - the row headers - on the second page. That makes it hard for users to read this report because the layout requires them to flip back and forth between the current page and the first page of the report. You can fix this behavior by finding the RepeatRowHeaders of the tablix report item and changing its value to True. The second (and subsequent pages) of the matrix now look like the image shown in Figure 3. The problem with this approach is that the number of printed pages to flip through is unpredictable when you have a large number of potential columns. What if you want to include all columns on the same page? You can take advantage of the repeating behavior of a tablix and get repeating columns by embedding one tablix inside of another. For this example, I'm using SQL Server 2008 R2 Reporting Services. You can get similar results with SQL Server 2008. (In fact, you could probably do something similar in SQL Server 2005, but I haven't tested it. The steps would be slightly different because you would be working with the old-style matrix as compared to the new-style tablix discussed in this post.) I created a dataset that queries AdventureWorksDW2008 tables: SELECT TOP (100) e.LastName + ', ' + e.FirstName AS EmployeeName, d.FullDateAlternateKey, f.SalesOrderNumber, p.EnglishProductName, sum(SalesAmount) as SalesAmount FROM FactResellerSales AS f INNER JOIN DimProduct AS p ON p.ProductKey = f.ProductKey INNER JOIN DimDate AS d ON d.DateKey = f.OrderDateKey INNER JOIN DimEmployee AS e ON e.EmployeeKey = f.EmployeeKey GROUP BY p.EnglishProductName, d.FullDateAlternateKey, e.LastName + ', ' + e.FirstName, f.SalesOrderNumber ORDER BY EmployeeName, f.SalesOrderNumber, p.EnglishProductName To start the report: Add a matrix to the report body and drag Employee Name to the row header, which also creates a group. Next drag SalesOrderNumber below Employee Name in the Row Groups panel, which creates a second group and a second column in the row header section of the matrix, as shown in Figure 4. Now for some trickiness. Add another column to the row headers. This new column will be associated with the existing EmployeeName group rather than causing BIDS to create a new group. To do this, right-click on the EmployeeName textbox in the bottom row, point to Insert Column, and then click Inside Group-Right. Then add the SalesOrderNumber field to this new column. By doing this, you're creating a report that repeats a set of columns for each EmployeeName/SalesOrderNumber combination that appears in the data. Next, modify the first row group's expression to group on both EmployeeName and SalesOrderNumber. In the Row Groups section, right-click EmployeeName, click Group Properties, click the Add button, and select [SalesOrderNumber]. Now you need to configure the columns to repeat. Rather than use the Columns group of the matrix like you might expect, you're going to use the textbox that belongs to the second group of the tablix as a location for embedding other report items. First, clear out the text that's currently in the third column - SalesOrderNumber - because it's already added as a separate textbox in this report design. Then drag and drop a matrix into that textbox, as shown in Figure 5. Again, you need to do some tricks here to get the appearance and behavior right. We don't really want repeating rows in the embedded matrix, so follow these steps: Click on the Rows label which then displays RowGroup in the Row Groups pane below the report body. Right-click on RowGroup,click Delete Group, and select the option to delete associated rows and columns. As a result, you get a modified matrix which has only a ColumnGroup in it, with a row above a double-dashed line for the column group and a row below the line for the aggregated data. Let's continue: Drag EnglishProductName to the data textbox (below the line). Add a second data row by right-clicking EnglishProductName, pointing to Insert Row, and clicking Below. Add the SalesAmount field to the new data textbox. Now eliminate the column group row without eliminating the group. To do this, right-click the row above the double-dashed line, click Delete Rows, and then select Delete Rows Only in the message box. Now you're ready for the fit and finish phase: Resize the column containing the embedded matrix so that it fits completely. Also, the final column in the matrix is for the column group. You can't delete this column, but you can make it as small as possible. Just click on the matrix to display the row and column handles, and then drag the right edge of the rightmost column to the left to make the column virtually disappear. Next, configure the groups so that the columns of the embedded matrix will wrap. In the Column Groups pane, right-click ColumnGroup1 and click on the expression button (labeled fx) to the right of Group On [EnglishProductName]. Replace the expression with the following: =RowNumber("SalesOrderNumber" ). We use SalesOrderNumber here because that is the name of the group that "contains" the embedded matrix. The next step is to configure the number of columns to display before wrapping. Click any cell in the matrix that is not inside the embedded matrix, and then double-click the second group in the Row Groups pane - SalesOrderNumber. Change the group expression to the following expression: =Ceiling(RowNumber("EmployeeName")/3) The last step is to apply formatting. In my example, I set the SalesAmount textbox's Format property to C2 and also right-aligned the text in both the EnglishProductName and the SalesAmount textboxes. And voila - Figure 6 shows a matrix report with wrapping columns. Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

Interesting things – Twitter annotations and your phone as a web server

- by jamiet

I overheard/read a couple of things today that really made me, data junkie that I am, take a step back and think, “Hmmm, yeah, that could be really interesting” and I wanted to make a note of them here so that (a) I could bring them to the attention of anyone that happens to read this and (b) I can maybe come back here in a few years and see if either of these have come to fruition. Your phone as a web server While listening to Jon Udell’s (twitter) “Interviews with Innovators Podcast” today in which he interviewed Herbert Van de Sompel (twitter) about his Momento project. During the interview Jon and Herbert made the following remarks: Jon: [some people] really had this vision of a web of servers, the notion that every node on the internet, every connected entity, is potentially a server and a client…we can see where we’re getting to a point where these endpoint devices we have in our pockets are going to be massively capable and it may be in the not too distant future that significant chunks of the web archive will be cached all over the place including on your own machine… Herbert: wasn’t it Opera who at one point turned your browser into a server? That really got my brain ticking. We all carry a mobile phone with us and therefore we all potentially carry a mobile web server with us as well and to my mind the only thing really stopping that from happening is the capabilities of the phone hardware, the capabilities of the network infrastructure and the will to just bloody do it. Certainly all the standards required for addressing a web server on a phone already exist (to this uninitiated observer DNS and IPv6 seem to solve that problem) so why not? I tweeted about the idea and Rory Street answered back with “why would you want a phone to be a web server?”: Its a fair question and one that I would like to try and answer. Mobile phones are increasingly becoming our window onto the world as we use them to upload messages to Twitter, record our location on FourSquare or interact with our friends on Facebook but in each of these cases some other service is acting as our intermediary; to see what I’m thinking you have to go via Twitter, to see where I am you have to go to FourSquare (I’m using ‘I’ liberally, I don’t actually use FourSquare before you ask). Why should this have to be the case? Why can’t that data be decentralised? Why can’t we be masters of our own data universe? If my phone acted as a web server then I could expose all of that information without needing those intermediary services. I see a time when we can pass around URLs such as the following: http://jamiesphone.net/location/current - Where is Jamie right now? http://jamiesphone.net/location/2010-04-21 – Where was Jamie on 21st April 2010? http://jamiesphone.net/thoughts/current – What’s on Jamie’s mind right now? http://jamiesphone.net/blog – What documents is Jamie sharing with me? http://jamiesphone.net/calendar/next7days – Where is Jamie planning to be over the next 7 days? and those URLs get served off of the phone in our pockets. If we govern that data then we can control who has access to it and (crucially) how long its available for. Want to wipe yourself off the face of the web? its pretty easy if you’re in control of all the data – just turn your phone off. None of this exists today but I look forward to a time when it does. Opera really were onto something last June when they announced Opera Unite (admittedly Unite only works because Opera provide an intermediary DNS-alike system – it isn’t totally decentralised). Opening up Twitter annotations Last week Twitter held their first developer conference called Chirp where they announced an upcoming new feature called ‘Twitter Annotations’; in short this will allow us to attach metadata to a Tweet thus enhancing the tweet itself. Think of it as a richer version of hashtags. To think of it another way Twitter are turning their data into a humongous Entity-Attribute-Value or triple-tuple store. That alone has huge implications both for the web and Twitter as a whole – the ability to enrich that 140 characters data and thus make it more useful is indeed compelling however today I stumbled upon a blog post from Eugene Mandel entitled Tweet Annotations – a Way to a Metadata Marketplace? where he proposed the idea of allowing tweets to have metadata added by people other than the person who tweeted the original tweet. This idea really fascinated me especially when I read some of the potential uses that Eugene and his commenters suggested. They included: Amazon could attach an ISBN to a tweet that mentions a book. Specialist clients apps for book lovers could be built up around this metadata. Advertisers could pay to place adverts in metadata. The revenue generated from those adverts could be shared with the tweeter or people who add the metadata. Granted, allowing anyone to add metadata to a tweet has the potential to create a spam problem the like of which we haven’t even envisaged but spam hasn’t halted the growth of the web and neither should it halt the growth of data annotations either. The original tweeter should of course be able to determine who can add metadata and whether it should be moderated. As Eugene says himself: Opening publishing tweet annotations to anyone will open the way to a marketplace of metadata where client developers, data mining companies and advertisers can add new meaning to Twitter and build innovative businesses. What Eugene and his followers did not mention is what I think is potentially the most fascinating use of opening up annotations. Google’s success today is built on their page rank algorithm that measures the validity of a web page by the number of incoming links to it and the page rank of the sites containing those links – its a system built on reputation. Twitter annotations could open up a new paradigm however – let’s call it People rank- where reputation can be measured by the metadata that people choose to apply to links and the websites containing those links. Its not hard to see why Google and Microsoft have paid big bucks to get access to the Twitter firehose! Neither of these features, phones as a web server or the ability to add annotations to other people’s tweets, exist today but I strongly believe that they could dramatically enhance the web as we know it today. I hope to look back on this blog post in a few years in the knowledge that these ideas have been put into place. @Jamiet Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

Simplify your Ajax code by using jQuery Global Ajax Handlers and ajaxSetup low-level interface

- by hajan

Creating web applications with consistent layout and user interface is very important for your users. In several ASP.NET projects I’ve completed lately, I’ve been using a lot jQuery and jQuery Ajax to achieve rich user experience and seamless interaction between the client and the server. In almost all of them, I took advantage of the nice jQuery global ajax handlers and jQuery ajax functions. Let’s say you build web application which mainly interacts using Ajax post and get to accomplish various operations. As you may already know, you can easily perform Ajax operations using jQuery Ajax low-level method or jQuery $.get, $.post, etc. Simple get example: $.get("/Home/GetData", function (d) { alert(d); }); As you can see, this is the simplest possible way to make Ajax call. What it does in behind is constructing low-level Ajax call by specifying all necessary information for the request, filling with default information set for the required properties such as data type, content type, etc... If you want to have some more control over what is happening with your Ajax Request, you can easily take advantage of the global ajax handlers. In order to register global ajax handlers, jQuery API provides you set of global Ajax methods. You can find all the methods in the following link http://api.jquery.com/category/ajax/global-ajax-event-handlers/, and these are: ajaxComplete ajaxError ajaxSend ajaxStart ajaxStop ajaxSuccess And the low-level ajax interfaces http://api.jquery.com/category/ajax/low-level-interface/: ajax ajaxPrefilter ajaxSetup For global settings, I usually use ajaxSetup combining it with the ajax event handlers. $.ajaxSetup is very good to help you set default values that you will use in all of your future Ajax Requests, so that you won’t need to repeat the same properties all the time unless you want to override the default settings. Mainly, I am using global ajaxSetup function similarly to the following way: $.ajaxSetup({ cache: false, error: function (x, e) { if (x.status == 550) alert("550 Error Message"); else if (x.status == "403") alert("403. Not Authorized"); else if (x.status == "500") alert("500. Internal Server Error"); else alert("Error..."); }, success: function (x) { //do something global on success... } }); .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Now, you can make ajax call using low-level $.ajax interface and you don’t need to worry about specifying any of the properties we’ve set in the $.ajaxSetup function. So, you can create your own ways to handle various situations when your Ajax requests are occurring. Sometimes, some of your Ajax Requests may take much longer than expected… So, in order to make user friendly UI that will show some progress bar or animated image that something is happening in behind, you can combine ajaxStart and ajaxStop methods to do the same. First of all, add one <div id=”loading” style=”display:none;”> <img src="@Url.Content("~/Content/images/ajax-loader.gif")" alt="Ajax Loader" /></div> anywhere on your Master Layout / Master page (you can download nice ajax loading images from http://ajaxload.info/). Then, add the following two handlers: $(document).ajaxStart(function () { $("#loading").attr("style", "position:absolute; z-index: 1000; top: 0px; "+ "left:0px; text-align: center; display:none; background-color: #ddd; "+ "height: 100%; width: 100%; /* These three lines are for transparency "+ "in all browsers. */-ms-filter:\"progid:DXImageTransform.Microsoft.Alpha(Opacity=50)\";"+ " filter: alpha(opacity=50); opacity:.5;"); $("#loading img").attr("style", "position:relative; top:40%; z-index:5;"); $("#loading").show(); }); $(document).ajaxStop(function () { $("#loading").removeAttr("style"); $("#loading img").removeAttr("style"); $("#loading").hide(); }); .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Note: While you can reorganize the style in a more reusable way, since these are global Ajax Start/Stop, it is very possible that you won’t use the same style in other places. With this way, you will see that now for any ajax request in your web site or application, you will have the loading image appearing providing better user experience. What I’ve shown is several useful examples on how to simplify your Ajax code by using Global Ajax Handlers and the low-level AjaxSetup function. Of course, you can do a lot more with the other methods as well. Hope this was helpful. Regards, Hajan

Use an Ubuntu Live CD to Securely Wipe Your PC’s Hard Drive

- by Trevor Bekolay

Deleting files or quickly formatting a drive isn’t enough for sensitive personal information. We’ll show you how to get rid of it for good using a Ubuntu Live CD. When you delete a file in Windows, Ubuntu, or any other operating system, it doesn’t actually destroy the data stored on your hard drive, it just marks that data as “deleted.” If you overwrite it later, then that data is generally unrecoverable, but if the operating system don’t happen to overwrite it, then your data is still stored on your hard drive, recoverable by anyone who has the right software. By securely delete files or entire hard drives, your data will be gone for good. Note: Modern hard drives are extremely sophisticated, as are the experts who recover data for a living. There is no guarantee that the methods covered in this article will make your data completely unrecoverable; however, they will make your data unrecoverable to the majority of recovery methods, and all methods that are readily available to the general public. Shred individual files Most of the data stored on your hard drive is harmless, and doesn’t reveal anything about you. If there are just a few files that you know you don’t want someone else to see, then the easiest way to get rid of them is a built-in Linux utility called shred. Open a terminal window by clicking on Applications at the top-left of the screen, then expanding the Accessories menu and clicking on Terminal. Navigate to the file that you want to delete using cd to change directories and ls to list the files and folders in the current directory. As an example, we’ve got a file called BankInfo.txt on a Windows NTFS-formatted hard drive. We want to delete it securely, so we’ll call shred by entering the following in the terminal window: shred <file> which is, in our example: shred BankInfo.txt Notice that our BankInfo.txt file still exists, even though we’ve shredded it. A quick look at the contents of BankInfo.txt make it obvious that the file has indeed been securely overwritten. We can use some command-line arguments to make shred delete the file from the hard drive as well. We can also be extra-careful about the shredding process by upping the number of times shred overwrites the original file. To do this, in the terminal, type in: shred –remove –iterations=<num> <file> By default, shred overwrites the file 25 times. We’ll double this, giving us the following command: shred –remove –iterations=50 BankInfo.txt BankInfo.txt has now been securely wiped on the physical disk, and also no longer shows up in the directory listing. Repeat this process for any sensitive files on your hard drive! Wipe entire hard drives If you’re disposing of an old hard drive, or giving it to someone else, then you might instead want to wipe your entire hard drive. shred can be invoked on hard drives, but on modern file systems, the shred process may be reversible. We’ll use the program wipe to securely delete all of the data on a hard drive. Unlike shred, wipe is not included in Ubuntu by default, so we have to install it. Open up the Synaptic Package Manager by clicking on System in the top-left corner of the screen, then expanding the Administration folder and clicking on Synaptic Package Manager. wipe is part of the Universe repository, which is not enabled by default. We’ll enable it by clicking on Settings > Repositories in the Synaptic Package Manager window. Check the checkbox next to “Community-maintained Open Source software (universe)”. Click Close. You’ll need to reload Synaptic’s package list. Click on the Reload button in the main Synaptic Package Manager window. Once the package list has been reloaded, the text over the search field will change to “Rebuilding search index”. Wait until it reads “Quick search,” and then type “wipe” into the search field. The wipe package should come up, along with some other packages that perform similar functions. Click on the checkbox to the left of the label “wipe” and select “Mark for Installation”. Click on the Apply button to start the installation process. Click the Apply button on the Summary window that pops up. Once the installation is done, click the Close button and close the Synaptic Package Manager window. Open a terminal window by clicking on Applications in the top-left of the screen, then Accessories > Terminal. You need to figure our the correct hard drive to wipe. If you wipe the wrong hard drive, that data will not be recoverable, so exercise caution! In the terminal window, type in: sudo fdisk -l A list of your hard drives will show up. A few factors will help you identify the right hard drive. One is the file system, found in the System column of the list – Windows hard drives are usually formatted as NTFS (which shows up as HPFS/NTFS). Another good identifier is the size of the hard drive, which appears after its identifier (highlighted in the following screenshot). In our case, the hard drive we want to wipe is only around 1 GB large, and is formatted as NTFS. We make a note of the label found under the the Device column heading. If you have multiple partitions on this hard drive, then there will be more than one device in this list. The wipe developers recommend wiping each partition separately. To start the wiping process, type the following into the terminal: sudo wipe <device label> In our case, this is: sudo wipe /dev/sda1 Again, exercise caution – this is the point of no return! Your hard drive will be completely wiped. It may take some time to complete, depending on the size of the drive you’re wiping. Conclusion If you have sensitive information on your hard drive – and chances are you probably do – then it’s a good idea to securely delete sensitive files before you give away or dispose of your hard drive. The most secure way to delete your data is with a few swings of a hammer, but shred and wipe from a Ubuntu Live CD is a good alternative!

Configuring Fed Authentication Methods in OIF / IdP

- by Damien Carru

In this article, I will provide examples on how to configure OIF/IdP to map OAM Authentication Schemes to Federation Authentication Methods, based on the concepts introduced in my previous entry. I will show examples for the three protocols supported by OIF: SAML 2.0 SSO SAML 1.1 SSO OpenID 2.0 Enjoy the reading! Configuration As I mentioned in my previous article, mapping Federation Authentication Methods to OAM Authentication Schemes is protocol dependent, since the methods are defined in the various protocols (SAML 2.0, SAML 1.1, OpenID 2.0). As such, the WLST commands to set those mappings will involve: Either the SP Partner Profile and affect all Partners referencing that profile, which do not override the Federation Authentication Method to OAM Authentication Scheme mappings Or the SP Partner entry, which will only affect the SP Partner It is important to note that if an SP Partner is configured to define one or more Federation Authentication Method to OAM Authentication Scheme mappings, then all the mappings defined in the SP Partner Profile will be ignored. WLST Commands The two OIF WLST commands that can be used to define mapping Federation Authentication Methods to OAM Authentication Schemes are: addSPPartnerProfileAuthnMethod() to define a mapping on an SP Partner Profile, taking as parameters: The name of the SP Partner Profile The Federation Authentication Method The OAM Authentication Scheme name addSPPartnerAuthnMethod() to define a mapping on an SP Partner , taking as parameters: The name of the SP Partner The Federation Authentication Method The OAM Authentication Scheme name Note: I will discuss in a subsequent article the other parameters of those commands. In the next sections, I will show examples on how to use those methods: For SAML 2.0, I will configure the SP Partner Profile, that will apply all the mappings to SP Partners referencing this profile, unless they override mapping definition For SAML 1.1, I will configure the SP Partner. For OpenID 2.0, I will configure the SP/RP Partner SAML 2.0 Test Setup In this setup, OIF is acting as an IdP and is integrated with a remote SAML 2.0 SP partner identified by AcmeSP. In this test, I will perform Federation SSO with OIF/IdP configured to: Use LDAPScheme as the Authentication Scheme Use BasicScheme as the Authentication Scheme Map BasicSessionScheme to the urn:oasis:names:tc:SAML:2.0:ac:classes:Password Federation Authentication Method Use OAMLDAPPluginAuthnScheme as the Authentication Scheme Map OAMLDAPPluginAuthnScheme to the urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport Federation Authentication Method LDAPScheme as Authentication Scheme Using the OOTB settings regarding user authentication in OAM, the user will be challenged via a FORM based login page based on the LDAPScheme. Also the default Federation Authentication Method mappings configuration maps only the urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport to LDAPScheme (also marked as the default scheme used for authentication), FAAuthScheme, BasicScheme and BasicFAScheme. After authentication via FORM, OIF/IdP would issue an Assertion similar to: <samlp:Response ...> <saml:Issuer ...>https://idp.com/oam/fed</saml:Issuer> <samlp:Status> <samlp:StatusCode Value="urn:oasis:names:tc:SAML:2.0:status:Success"/> </samlp:Status> <saml:Assertion ...> <saml:Issuer ...>https://idp.com/oam/fed</saml:Issuer> <dsig:Signature> ... </dsig:Signature> <saml:Subject> <saml:NameID ...>[email protected]</saml:NameID> <saml:SubjectConfirmation Method="urn:oasis:names:tc:SAML:2.0:cm:bearer"> <saml:SubjectConfirmationData .../> </saml:SubjectConfirmation> </saml:Subject> <saml:Conditions ...> <saml:AudienceRestriction> <saml:Audience>https://acme.com/sp</saml:Audience> </saml:AudienceRestriction> </saml:Conditions> <saml:AuthnStatement AuthnInstant="2014-03-21T20:53:55Z" SessionIndex="id-6i-Dm0yB-HekG6cejktwcKIFMzYE8Yrmqwfd0azz" SessionNotOnOrAfter="2014-03-21T21:53:55Z"> <saml:AuthnContext> <saml:AuthnContextClassRef> urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport </saml:AuthnContextClassRef> </saml:AuthnContext> </saml:AuthnStatement> </saml:Assertion></samlp:Response> BasicScheme as Authentication Scheme For this test, I will switch the default Authentication Scheme for the SP Partner Profile to BasicScheme instead of LDAPScheme. I will use the OIF WLST setSPPartnerProfileDefaultScheme() command and specify which scheme to be used as the default for the SP Partner Profile referenced by AcmeSP (which is saml20-sp-partner-profile in this case: getFedPartnerProfile("AcmeSP", "sp") ): Enter the WLST environment by executing:$IAM_ORACLE_HOME/common/bin/wlst.sh Connect to the WLS Admin server:connect() Navigate to the Domain Runtime branch:domainRuntime() Execute the setSPPartnerProfileDefaultScheme() command:setSPPartnerProfileDefaultScheme("saml20-sp-partner-profile", "BasicScheme") Exit the WLST environment:exit() The user will now be challenged via HTTP Basic Authentication defined in the BasicScheme for AcmeSP. Also, as noted earlier, the default Federation Authentication Method mappings configuration maps only the urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport to LDAPScheme (also marked as the default scheme used for authentication), FAAuthScheme, BasicScheme and BasicFAScheme.

No Federation Authentication Method is defined OOTB for OpenID 2.0, so if the IdP/OP issue an SSO response with a PAPE Response element, it will specify the scheme name instead of Federation Authentication Methods After authentication via FORM, OIF/IdP would issue an SSO Response similar to: https://acme.com/openid?refid=id-9PKVXZmRxAeDYcgLqPm36ClzOMA-&openid.ns=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0&openid.mode=id_res&openid.op_endpoint=https%3A%2F%2Fidp.com%2Fopenid&openid.claimed_id=https%3A%2F%2Fidp.com%2Fopenid%3Fid%3Did-38iCmmlAVEXPsFjnFVKArfn5RIiF75D5doorhEgqqPM%3D&openid.identity=https%3A%2F%2Fidp.com%2Fopenid%3Fid%3Did-38iCmmlAVEXPsFjnFVKArfn5RIiF75D5doorhEgqqPM%3D&openid.return_to=https%3A%2F%2Facme.com%2Fopenid%3Frefid%3Did-9PKVXZmRxAeDYcgLqPm36ClzOMA-&openid.response_nonce=2014-03-24T19%3A20%3A06Zid-YPa2kTNNFftZkgBb460jxJGblk2g--iNwPpDI7M1&openid.assoc_handle=id-6a5S6zhAKaRwQNUnjTKROREdAGSjWodG1el4xyz3&openid.ns.ax=http%3A%2F%2Fopenid.net%2Fsrv%2Fax%2F1.0&openid.ax.mode=fetch_response&openid.ax.type.attr0=http%3A%2F%2Fsession%2Fcount&openid.ax.value.attr0=1&openid.ax.type.attr1=http%3A%2F%2Fopenid.net%2Fschema%2FnamePerson%2Ffriendly&openid.ax.value.attr1=My+name+is+Bobby+Smith&openid.ax.type.attr2=http%3A%2F%2Fschemas.openid.net%2Fax%2Fapi%2Fuser_id&openid.ax.value.attr2=bob&openid.ax.type.attr3=http%3A%2F%2Faxschema.org%2Fcontact%2Femail&openid.ax.value.attr3=bob%40oracle.com&openid.ax.type.attr4=http%3A%2F%2Fsession%2Fipaddress&openid.ax.value.attr4=10.145.120.253&openid.ns.pape=http%3A%2F%2Fspecs.openid.net%2Fextensions%2Fpape%2F1.0&openid.pape.auth_time=2014-03-24T19%3A20%3A05Z&openid.pape.auth_policies=LDAPScheme&openid.signed=op_endpoint%2Cclaimed_id%2Cidentity%2Creturn_to%2Cresponse_nonce%2Cassoc_handle%2Cns.ax%2Cax.mode%2Cax.type.attr0%2Cax.value.attr0%2Cax.type.attr1%2Cax.value.attr1%2Cax.type.attr2%2Cax.value.attr2%2Cax.type.attr3%2Cax.value.attr3%2Cax.type.attr4%2Cax.value.attr4%2Cns.pape%2Cpape.auth_time%2Cpape.auth_policies&openid.sig=mYMgbGYSs22l8e%2FDom9NRPw15u8%3D Mapping LDAPScheme To map the LDAP Scheme to the http://schemas.openid.net/pape/policies/2007/06/phishing-resistant and http://openid-policies/password-protected policies Federation Authentication Methods, I will execute the addSPPartnerAuthnMethod() method (the policies will be comma separated): Enter the WLST environment by executing:$IAM_ORACLE_HOME/common/bin/wlst.sh Connect to the WLS Admin server:connect() Navigate to the Domain Runtime branch:domainRuntime() Execute the addSPPartnerAuthnMethod() command:addSPPartnerAuthnMethod("AcmeRP", "http://schemas.openid.net/pape/policies/2007/06/phishing-resistant,http://openid-policies/password-protected", "LDAPScheme") Exit the WLST environment:exit() After authentication via FORM, OIF/IdP would now issue an Assertion similar to (see that the method was changed from LDAPScheme to the two policies): https://acme.com/openid?refid=id-9PKVXZmRxAeDYcgLqPm36ClzOMA-&openid.ns=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0&openid.mode=id_res&openid.op_endpoint=https%3A%2F%2Fidp.com%2Fopenid&openid.claimed_id=https%3A%2F%2Fidp.com%2Fopenid%3Fid%3Did-38iCmmlAVEXPsFjnFVKArfn5RIiF75D5doorhEgqqPM%3D&openid.identity=https%3A%2F%2Fidp.com%2Fopenid%3Fid%3Did-38iCmmlAVEXPsFjnFVKArfn5RIiF75D5doorhEgqqPM%3D&openid.return_to=https%3A%2F%2Facme.com%2Fopenid%3Frefid%3Did-9PKVXZmRxAeDYcgLqPm36ClzOMA-&openid.response_nonce=2014-03-24T19%3A20%3A06Zid-YPa2kTNNFftZkgBb460jxJGblk2g--iNwPpDI7M1&openid.assoc_handle=id-6a5S6zhAKaRwQNUnjTKROREdAGSjWodG1el4xyz3&openid.ns.ax=http%3A%2F%2Fopenid.net%2Fsrv%2Fax%2F1.0&openid.ax.mode=fetch_response&openid.ax.type.attr0=http%3A%2F%2Fsession%2Fcount&openid.ax.value.attr0=1&openid.ax.type.attr1=http%3A%2F%2Fopenid.net%2Fschema%2FnamePerson%2Ffriendly&openid.ax.value.attr1=My+name+is+Bobby+Smith&openid.ax.type.attr2=http%3A%2F%2Fschemas.openid.net%2Fax%2Fapi%2Fuser_id&openid.ax.value.attr2=bob&openid.ax.type.attr3=http%3A%2F%2Faxschema.org%2Fcontact%2Femail&openid.ax.value.attr3=bob%40oracle.com&openid.ax.type.attr4=http%3A%2F%2Fsession%2Fipaddress&openid.ax.value.attr4=10.145.120.253&openid.ns.pape=http%3A%2F%2Fspecs.openid.net%2Fextensions%2Fpape%2F1.0&openid.pape.auth_time=2014-03-24T19%3A20%3A05Z&openid.pape.auth_policies=http%3A%2F%2Fschemas.openid.net%2Fpape%2Fpolicies%2F2007%2F06%2Fphishing-resistant+http%3A%2F%2Fopenid-policies%2Fpassword-protected&openid.signed=op_endpoint%2Cclaimed_id%2Cidentity%2Creturn_to%2Cresponse_nonce%2Cassoc_handle%2Cns.ax%2Cax.mode%2Cax.type.attr0%2Cax.value.attr0%2Cax.type.attr1%2Cax.value.attr1%2Cax.type.attr2%2Cax.value.attr2%2Cax.type.attr3%2Cax.value.attr3%2Cax.type.attr4%2Cax.value.attr4%2Cns.pape%2Cpape.auth_time%2Cpape.auth_policies&openid.sig=mYMgbGYSs22l8e%2FDom9NRPw15u8%3D In the next article, I will cover how OIF/IdP can be configured so that an SP can request a specific Federation Authentication Method to challenge the user during Federation SSO.Cheers,Damien Carru

Customize your icons in Windows 7 and Vista

- by Matthew Guay

Want to change out the icons on your desktop and more? Personalizing your icons is a great way to make your PC uniquely yours,, and today we show you how to grab unique icons, and default Winnows. to be your own. Change the icon for Computer, Recycle Bin, Network, and your User folder Right-click on the desktop, and select Personalize. Now, click the “Change desktop icons” link on the left sidebar in the Personalization window. The window looks slightly different in Windows Vista, but the link is the same. Select the icon you wish to change, and click the Change Icon button. In Windows 7, you will also notice a box to choose whether or not to allow themes to change icons, and you can uncheck it if you don’t want themes to change your icon settings. You can select one of the other included icons, or click browse to find the icon you want. Click Ok when you are finished. Change Folder icons You can easily change the icon on most folders in Windows Vista and 7. Simply right-click on the folder and select properties. Click the Customize tab, and then click the Change Icon button. This will open the standard dialog to change your icon, so proceed as normal. This basically just creates a hidden desktop.ini file in the folder containing the following or similar data: [.ShellClassInfo]IconFile=%SystemRoot%\system32\SHELL32.dllIconIndex=20 You could manually create or edit the file if you choose, instead of using the dialogs. Simply create a new text file named desktop.ini with this same information, or edit the existing one. Change the IconFile line to the location of your icon. If you are pointing to a .ico file you should change the IconIndex line to 0 instead. Note that this isn’t available for all folders, for instance you can’t use this to change the icon for the Windows folder. In Windows 7, please note that you cannot change the icon of folder inside a library. So if you are browsing your Documents library and would like to change an icon in that folder, right-click on it and select Open folder location. Now you can change the icon as above. And if you would like to change a Library’s icon itself, then check out this tutorial: Change Your Windows 7 Library Icons the Easy Way Change the icon of any file type Want to make you files easier to tell apart? Check out our tutorial on how to simply do this: Change a File Type’s Icon in Windows 7 Change the icon of any Application Shortcut To change the icon of a shortcut on your desktop, start menu, or in Explorer, simply right-click on the icon and select Properties. In the Shortcut tab, click the Change Icon button. Now choose one of the other available icons or click browse to find the icon you want. Change Icons of Running Programs in the Windows 7 taskbar If your computer is running Windows 7, you can customize the icon of any program running in the taskbar! This only works on applications that are running but not pinned to the taskbar, so if you want to customize a pinned icon you may want to unpin it before customizing it. But the interesting thing about this trick is that it can customize any icon anything running in the taskbar, including things like Control Panel! Right-click or click and push up to open the jumplist on the icon, and then right-click on the program’s name and select Properties. Here we are customizing Control Panel, but you can do this on any application icon. Now, click Change Icon as usual. Select an icon you want (We switched the Control Panel icon to the Security Shield), or click Browse to find another icon. Click Ok when finished, and then close the application window. The next time you open the program (or Control Panel in our example), you will notice your new icon on its taskbar icon. Please note that this only works on applications that are currently running and are not pinned to the taskbar. Strangely, if the application is pinned to the taskbar, you can still click Properties and change the icon, but the change will not show up. Change the icon on any Drive on your Computer You can easily change the icon on your internal hard drives and portable drives with the free Drive Icon Changer application. Simply download and unzip the file (link below), and then run the application as administrator by right-clicking on the icon and selecting “Run as administrator”. Now, select the drive that you want to change the icon of, and select your desired icon file. Click Save, and Drive Icon Changer will let you know that the icon has been changed successfully. You will then need to reboot your computer to complete the changes. Simply click Yes to reboot. Now, our Drive icon is changed from this default image: to a Laptop icon we chose! You can do this to any drive in your computer, or to removable drives such as USB flash drives. When you change these drives icons, the new icon will appear on any computer you insert the drive into. Also, if you wish to remove the icon change, simply run the Drive Icon Changer again and remove the icon path. Download Drive Icon Changer This application actually simply creates or edits a hidden Autorun.inf file on the top of your drive. You can edit or create the file yourself by hand if you’d like; simply include the following information in the file, and save it in the top directory of your drive: [autorun]ICON=[path of your icon] Remove Arrow from shortcut icons Many people don’t like the arrow on the shortcut icon, and there are two easy ways to do this. If you’re running the 32 bit version of Windows Vista or 7, simply use the Vista Shortcut Overlay Remover. If your computer is running the 64 bit version of Windows Vista or 7, use the Ultimate Windows Tweaker instead. Simply select the Additional Tweaks section, and check the “Remove arrows from Shortcut Icons.” For more info and download links check out this article: Disable Shortcut Icon Arrow Overlay in Windows 7 or Vista Closing: This gives you a lot of ways to customize almost any icon on your computer, so you can make it look just like you want it to.

Replacing jQuery.live() with jQuery.on()

- by Rick Strahl

jQuery 1.9 and 1.10 have introduced a host of changes, but for the most part these changes are mostly transparent to existing application usage of jQuery. After spending some time last week with a few of my projects and going through them with a specific eye for jQuery failures I found that for the most part there wasn't a big issue. The vast majority of code continues to run just fine with either 1.9 or 1.10 (which are supposed to be in sync but with 1.10 removing support for legacy Internet Explorer pre-9.0 versions). However, one particular change in the new versions has caused me quite a bit of update trouble, is the removal of the jQuery.live() function. This is my own fault I suppose - .live() has been deprecated for a while, but with 1.9 and later it was finally removed altogether from jQuery. In the past I had quite a bit of jQuery code that used .live() and it's one of the things that's holding back my upgrade process, although I'm slowly cleaning up my code and switching to the .on() function as the replacement. jQuery.live() jQuery.live() was introduced a long time ago to simplify handling events on matched elements that exist currently on the document and those that are are added in the future and also match the selector. jQuery uses event bubbling, special event binding, plus some magic using meta data attached to a parent level element to check and see if the original target event element matches the selected selected elements (for more info see Elijah Manor's comment below). An Example Assume a list of items like the following in HTML for example and further assume that the items in this list can be appended to at a later point. In this app there's a smallish initial list that loads to start, and as the user scrolls towards the end of the initial small list more items are loaded dynamically and added to the list.<div id="PostItemContainer" class="scrollbox"> <div class="postitem" data-id="4z6qhomm"> <div class="post-icon"></div> <div class="postitemheader"><a href="show/4z6qhomm" target="Content">1999 Buick Century For Sale!</a></div> <div class="postitemprice rightalign">$ 3,500 O.B.O.</div> <div class="smalltext leftalign">Jun. 07 @ 1:06am</div> <div class="post-byline">- Vehicles - Automobiles</div> </div> <div class="postitem" data-id="2jtvuu17"> <div class="postitemheader"><a href="show/2jtvuu17" target="Content">Toyota VAN 1987</a></div> <div class="postitemprice rightalign">$950</div> <div class="smalltext leftalign">Jun. 07 @ 12:29am</div> <div class="post-byline">- Vehicles - Automobiles</div> </div> … </div> With the jQuery.live() function you could easily select elements and hook up a click handler like this:$(".postitem").live("click", function() {...}); Simple and perfectly readable. The behavior of the .live handler generally was the same as the corresponding simple event handlers like .click(), except that you have to explicitly name the event instead of using one of the methods. Re-writing with jQuery.on() With .live() removed in 1.9 and later we have to re-write .live() code above with an alternative. The jQuery documentation points you at the .on() or .delegate() functions to update your code. jQuery.on() is a more generic event handler function, and it's what jQuery uses internally to map the high level event functions like .click(),.change() etc. that jQuery exposes. Using jQuery.on() however is not a one to one replacement of the .live() function. While .on() can handle events directly and use the same syntax as .live() did, you'll find if you simply switch out .live() with .on() that events on not-yet existing elements will not fire. IOW, the key feature of .live() is not working. You can use .on() to get the desired effect however, but you have to change the syntax to explicitly handle the event you're interested in on the container and then provide a filter selector to specify which elements you are actually interested in for handling the event for. Sounds more complicated than it is and it's easier to see with an example. For the list above hooking .postitem clicks, using jQuery.on() looks like this:$("#PostItemContainer").on("click", ".postitem", function() {...}); You specify a container that can handle the .click event and then provide a filter selector to find the child elements that trigger the the actual event. So here #PostItemContainer contains many .postitems, whose click events I want to handle. Any container will do including document, but I tend to use the container closest to the elements I actually want to handle the events on to minimize the event bubbling that occurs to capture the event. With this code I get the same behavior as with .live() and now as new .postitem elements are added the click events are always available. Sweet. Here's the full event signature for the .on() function: .on( events [, selector ] [, data ], handler(eventObject) ) Note that the selector is optional - if you omit it you essentially create a simple event handler that handles the event directly on the selected object. The filter/child selector required if you want life-like - uh, .live() like behavior to happen. While it's a bit more verbose than what .live() did, .on() provides the same functionality by being more explicit on what your parent container for trapping events is. .on() is good Practice even for ordinary static Element Lists As a side note, it's a good practice to use jQuery.on() or jQuery.delegate() for events in most cases anyway, using this 'container event trapping' syntax. That's because rather than requiring lots of event handlers on each of the child elements (.postitem in the sample above), there's just one event handler on the container, and only when clicked does jQuery drill down to find the matching filter element and tries to match it to the originating element. In the early days of jQuery I used manually build handlers that did this and manually drilled from the event object into the originalTarget to determine if it's a matching element. With later versions of jQuery the various event functions in jQuery essentially provide this functionality out of the box with functions like .on() and .delegate(). All of this is nothing new, but I thought I'd write this up because I have on a few occasions forgotten what exactly was needed to replace the many .live() function calls that litter my code - especially older code. This will be a nice reminder next time I have a memory blank on this topic. And maybe along the way I've helped one or two of you as well to clean up your .live() code…© Rick Strahl, West Wind Technologies, 2005-2013Posted in jQuery Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

ASP.NET and WIF: Showing custom profile username as User.Identity.Name

- by DigiMortal

I am building ASP.NET MVC application that uses external services to authenticate users. For ASP.NET users are fully authenticated when they are redirected back from external service. In system they are logically authenticated when they have created user profiles. In this posting I will show you how to force ASP.NET MVC controller actions to demand existence of custom user profiles. Using external authentication sources with AppFabric Suppose you want to be user-friendly and you don’t force users to keep in mind another username/password when they visit your site. You can accept logins from different popular sites like Windows Live, Facebook, Yahoo, Google and many more. If user has account in some of these services then he or she can use his or her account to log in to your site. If you have community site then you usually have support for user profiles too. Some of these providers give you some information about users and other don’t. So only thing in common you get from all those providers is some unique ID that identifies user in service uniquely. Image above shows you how new user joins your site. Existing users who already have profile are directed to users homepage after they are authenticated. You can read more about how to solve semi-authorized users problem from my blog posting ASP.NET MVC: Using ProfileRequiredAttribute to restrict access to pages. The other problem is related to usernames that we don’t get from all identity providers. Why is IIdentity.Name sometimes empty? The problem is described more specifically in my blog posting Identifying AppFabric Access Control Service users uniquely. Shortly the problem is that not all providers have claim called http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name. The following diagram illustrates what happens when user got token from AppFabric ACS and was redirected to your site. Now, when user was authenticated using Windows Live ID then we don’t have name claim in token and that’s why User.Identity.Name is empty. Okay, we can force nameidentifier to be used as name (we can do it in web.config file) but we have user profiles and we want username from profile to be shown when username is asked. Modifying name claim Now let’s force IClaimsIdentity to use username from our user profiles. You can read more about my profiles topic from my blog posting ASP.NET MVC: Using ProfileRequiredAttribute to restrict access to pages and you can find some useful extension methods for claims identity from my blog posting Identifying AppFabric Access Control Service users uniquely. Here is what we do to set User.Identity.Name: we will check if user has profile, if user has profile we will check if User.Identity.Name matches the name given by profile, if names does not match then probably identity provider returned some name for user, we will remove name claim and recreate it with correct username, we will add new name claim to claims collection. All this stuff happens in Application_AuthorizeRequest event of our web application. The code is here. protected void Application_AuthorizeRequest() { if (string.IsNullOrEmpty(User.Identity.Name)) { var identity = User.Identity; var profile = identity.GetProfile(); if (profile != null) { if (profile.UserName != identity.Name) { identity.RemoveName(); var claim = new Claim("http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name", profile.UserName); var claimsIdentity = (IClaimsIdentity)identity; claimsIdentity.Claims.Add(claim); } } } } RemoveName extension method is simple – it looks for name claims of IClaimsIdentity claims collection and removes them. public static void RemoveName(this IIdentity identity) { if (identity == null) return; var claimsIndentity = identity as ClaimsIdentity; if (claimsIndentity == null) return; for (var i = claimsIndentity.Claims.Count - 1; i >= 0; i--) { var claim = claimsIndentity.Claims[i]; if (claim.ClaimType == "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name") claimsIndentity.Claims.RemoveAt(i); } } And we are done. Now User.Identity.Name returns the username from user profile and you can use it to show username of current user everywhere in your site. Conclusion Mixing AppFabric Access Control Service and Windows Identity Foundation with custom authorization logic is not impossible but a little bit tricky. This posting finishes my little series about AppFabric ACS and WIF for this time and hopefully you found some useful tricks, tips, hacks and code pieces you can use in your own applications.

Change or Reset Windows Password from a Ubuntu Live CD

- by Trevor Bekolay

If you can’t log in even after trying your twelve passwords, or you’ve inherited a computer complete with password-protected profiles, worry not – you don’t have to do a fresh install of Windows. We’ll show you how to change or reset your Windows password from a Ubuntu Live CD. This method works for all of the NT-based version of Windows – anything from Windows 2000 and later, basically. And yes, that includes Windows 7. You’ll need a Ubuntu 9.10 Live CD, or a bootable Ubuntu 9.10 Flash Drive. If you don’t have one, or have forgotten how to boot from the flash drive, check out our article on creating a bootable Ubuntu 9.10 flash drive. The program that lets us manipulate Windows passwords is called chntpw. The steps to install it are different in 32-bit and 64-bit versions of Ubuntu. Installation: 32-bit Open up Synaptic Package Manager by clicking on System at the top of the screen, expanding the Administration section, and clicking on Synaptic Package Manager. chntpw is found in the universe repository. Repositories are a way for Ubuntu to group software together so that users are able to choose if they want to use only completely open source software maintained by Ubuntu developers, or branch out and use software with different licenses and maintainers. To enable software from the universe repository, click on Settings > Repositories in the Synaptic window. Add a checkmark beside the box labeled “Community-maintained Open Source software (universe)” and then click close. When you change the repositories you are selecting software from, you have to reload the list of available software. In the main Synaptic window, click on the Reload button. The software lists will be downloaded. Once downloaded, Synaptic must rebuild its search index. The label over the text field by the Search button will read “Rebuilding search index.” When it reads “Quick search,” type chntpw in the text field. The package will show up in the list. Click on the checkbox near the chntpw name. Click on Mark for Installation. chntpw won’t actually be installed until you apply the changes you’ve made, so click on the Apply button in the Synaptic window now. You will be prompted to accept the changes. Click Apply. The changes should be applied quickly. When they’re done, click Close. chntpw is now installed! You can close Synaptic Package Manager. Skip to the section titled Using chntpw to reset your password. Installation: 64-bit The version of chntpw available in Ubuntu’s universe repository will not work properly on a 64-bit machine. Fortunately, a patched version exists in Debian’s Unstable branch, so let’s download it from there and install it manually. Open Firefox. Whether it’s your preferred browser or not, it’s very readily accessible in the Ubuntu Live CD environment, so it will be the easiest to use. There’s a shortcut to Firefox in the top panel. Navigate to http://packages.debian.org/sid/amd64/chntpw/download and download the latest version of chntpw for 64-bit machines. Note: In most cases it would be best to add the Debian Unstable branch to a package manager, but since the Live CD environment will revert to its original state once you reboot, it’ll be faster to just download the .deb file. Save the .deb file to the default location. You can close Firefox if desired. Open a terminal window by clicking on Applications at the top-left of the screen, expanding the Accessories folder, and clicking on Terminal. In the terminal window, enter the following text, hitting enter after each line: cd Downloadssudo dpkg –i chntpw* chntpw will now be installed. Using chntpw to reset your password Before running chntpw, you will have to mount the hard drive that contains your Windows installation. In most cases, Ubuntu 9.10 makes this simple. Click on Places at the top-left of the screen. If your Windows drive is easily identifiable – usually by its size – then left click on it. If it is not obvious, then click on Computer and check out each hard drive until you find the correct one. The correct hard drive will have the WINDOWS folder in it. When you find it, make a note of the drive’s label that appears in the menu bar of the file browser. If you don’t already have one open, start a terminal window by going to Applications > Accessories > Terminal. In the terminal window, enter the commands cd /medials pressing enter after each line. You should see one or more strings of text appear; one of those strings should correspond with the string that appeared in the title bar of the file browser earlier. Change to that directory by entering the command cd <hard drive label> Since the hard drive label will be very annoying to type in, you can use a shortcut by typing in the first few letters or numbers of the drive label (capitalization matters) and pressing the Tab key. It will automatically complete the rest of the string (if those first few letters or numbers are unique). We want to switch to a certain Windows directory. Enter the command: cd WINDOWS/system32/config/ Again, you can use tab-completion to speed up entering this command. To change or reset the administrator password, enter: sudo chntpw SAM SAM is the file that contains your Windows registry. You will see some text appear, including a list of all of the users on your system. At the bottom of the terminal window, you should see a prompt that begins with “User Edit Menu:” and offers four choices. We recommend that you clear the password to blank (you can always set a new password in Windows once you log in). To do this, enter “1” and then “y” to confirm. If you would like to change the password instead, enter “2”, then your desired password, and finally “y” to confirm. If you would like to reset or change the password of a user other than the administrator, enter: sudo chntpw –u <username> SAM From here, you can follow the same steps as before: enter “1” to reset the password to blank, or “2” to change it to a value you provide. And that’s it! Conclusion chntpw is a very useful utility provided for free by the open source community.

Using Teleriks new LINQ implementation to create OData feeds

This week Telerik released a new LINQ implementation that is simple to use and produces domain models very fast. Built on top of the enterprise grade OpenAccess ORM, you can connect to any database that OpenAccess can connect to such as: SQL Server, MySQL, Oracle, SQL Azure, VistaDB, etc. While this is a separate LINQ implementation from traditional OpenAccess Entites, you can use the visual designer without ever interacting with OpenAccess, however, you can always hook into the advanced ORM features like caching, fetch plan optimization, etc, if needed. Just to show off how easy our LINQ implementation is to use, I will walk you through building an OData feed using Data Services Update for .NET Framework 3.5 SP1. (Memo to Microsoft: P-L-E-A-S-E hire someone from Apple to name your products.) How easy is it? If you have a fast machine, are skilled with the mouse, and type fast, you can do this in about 60 seconds via three easy steps. (I promise in about 2-3 weeks that you can do this in less then 30 seconds. Stay tuned for that.) Step 1 (15-20 seconds): Building your Domain Model In your web project in Visual Studio, right click on the project and select Add|New Item and select Telerik OpenAccess Domain Model as your item template. Give the file a meaningful name as well. Select your database type (SQL Server, SQL Azure, Oracle, MySQL, VistaDB, etc) and build the connection string. If you already have a Visual Studio connection string already saved, this step is trivial. Then select your tables, enter a name for your model and click Finish. In this case I connected to Northwind and selected only Customers, Orders, and Order Details. I named my model NorthwindEntities and will use that in my DataService. Step 2 (20-25 seconds): Adding and Configuring your Data Service In your web project in Visual Studio, right click on the project and select Add|New Item and select ADO .NET Data Service as your item template and name your service. In the code behind for your Data Service you have to make three small changes. Add the name of your Telerik Domain Model (entered in Step 1) as the DataService name (shown on line 6 below as NorthwindEntities) and uncomment line 11 and add a * to show all entities. Optionally if you want to take advantage of the DataService 3.5 updates, add line 13 (and change IDataServiceConfiguration to DataServiceConfiguration in line 9.) 1: using System.Data.Services; 2: using System.Data.Services.Common; 3: 4: namespace Telerik.RLINQ.Astoria.Web 5: { 6: public class NorthwindService : DataService<NorthwindEntities> 7: { 8: //change the IDataServiceConfigurationto DataServiceConfiguration 9: public static void InitializeService(DataServiceConfiguration config) 10: { 11: config.SetEntitySetAccessRule("*", EntitySetRights.All); 12: //take advantage of the "Astoria3.5 Update" features 13: config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V2; 14: } 15: } 16: } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Step 3 (~30 seconds): Adding the DataServiceKeys You now have to tell your data service what are the primary keys of each entity. To do this you have to create a new code file and create a few partial classes. If you type fast, use copy and paste from your first entity, and use a refactoring productivity tool, you can add these 6-8 lines of code or so in about 30 seconds. This is the most tedious step, but dont worry, Ive bribed some of the developers and our next update will eliminate this step completely. Just create a partial class for each entity you have mapped and add the attribute [DataServiceKey] on top of it along with the keys field name. If you have any complex properties, you will need to make them a primitive type, as I do in line 15. Create this as a separate file, dont manipulate the generated data access classes in case you want to regenerate them again later (even thought that would be much faster.) 1: using System.Data.Services.Common; 2: 3: namespace Telerik.RLINQ.Astoria.Web 4: { 5: [DataServiceKey("CustomerID")] 6: public partial class Customer 7: { 8: } 9: 10: [DataServiceKey("OrderID")] 11: public partial class Order 12: { 13: } 14: 15: [DataServiceKey(new string[] { "OrderID", "ProductID" })] 16: public partial class OrderDetail 17: { 18: } 19: 20: } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Done! Time to run the service. Now, lets run the service! Select the svc file and right click and say View in Browser. You will see your OData service and can interact with it in the browser. Now that you have an OData service set up, you can consume it in one of the many ways that OData is consumed: using LINQ, the Silverlight OData client, Excel PowerPivot, or PhP, etc. Happy Data Servicing!

Adaptive ADF/WebCenter template for the iPad

- by Maiko Rocha

One of my WebCenter Portal customers was asking about adaptive design with ADF/WebCenter Portal and how they could go about creating an adaptive iPad template for their WebCenter Portal application. They were looking not only for the out-of-the-box support for mobile Safari which is certified against PS5+ (11.1.1.6) for ADF/WebCenter - but also to create a specific template to streamline their workflow on the iPad. Seems like they wanted something in the lines of Yahoo! Mail provides for the iPad - so the example I will use is shamelessly inspired by Y! Mail's iPad UI. But first, let's quickly understand how can we bake in some adaptive goodness into ADF Faces. First thing we need to understand is, yes, there are a couple of constraints that we will need to work around, namely, the use or layout managers and skins. Please also keep in mind that I'm not and I don't pretend to be a web designer, much less an UX specialist, so feel free to leave your thoughts on the matter in the comments section. Now, back to the limitations. Layout Managers ADF Faces layout managers create an abstraction on top of the generated HTML code for a page so a developer doesn't need to be worried about how to size and dimension the UI layout (eg, af:panelStretchLayout). Although layout managers are very helpful, in this specific situation we will need to know a little bit more of how the final HTML is being rendered so we can apply the CSS class accordingly and create transition containers where the media queries will be applied - now, if you're using 11gR2 (11.1.2.2.3) there's the new component af:panelGridLayout (here and here) that will greatly improve creating responsive templates and pages because it is based on the grid/fluid systems and will generate straight out to DIVs on your final page. For now, I'm limited to PS5 and the af:panelStretchLayout component as a starting point because that's the release my customer is on. Skins You won't be able to use media queries, or use anything with "@" notation on the skin CSS file - the skin pre-processor will remove all extraneous "@" from the CSS file. The solution is to split your CSS in two separate files: a skin CSS file and plain CSS where you will add the media queries. The issue here is that you won't be able to use media queries for any faces components. We can, though, still apply the media queries for the components like af:panelGroupLayout and af:panelBorderLayout through their styleClass property to enable these components to be responsive to to the iPad orientation, by changing its dimensions, font sizes, hide/show areas, etc. Difference between responsive and adaptive design The best definition of adaptive vs responsive web design I could find is this: “Responsive web design,” as coined by Ethan Marcotte, means “fluid grids, fluid images/media & media queries.” “Adaptive web design,” as I use it, is about creating interfaces that adapt to the user’s capabilities (in terms of both form and function). To me, “adaptive web design” is just another term for “progressive enhancement” of which responsive web design can (an often should) be an integral part, but is a more holistic approach to web design in that it also takes into account varying levels of markup, CSS, JavaScript and assistive technology support. Responsive/adapative web design is much more than slapping an HTML template with CSS around your content or application. The content and application themselves are part of your web design - in other words, a responsive template is just an afterthought if it is not originating from a responsive design the involves the whole web application/s. Tips on responsive / adapative design with ADF/WebCenter Some of the tips listed below were already mentioned in multiple blog posts about ADF layout and skinning, but it is still worth remembering: a simple guideline for ADF/WebCenter apps would be to first create a high-level group of devices, for example: smartphones, tablets, and desktop. For each of these large groups, create the basic structure to provide responsiveness: a page template, a skin, and an external CSS: pagetemplate_smartphone.jspx, smartphone_skin.css, smartphone-responsive.css pagetemplate_tablet.jspx, tablet_skin.css, tablet-responsive.css pagetemplate_desktop.jspx, desktop_skin.css, desktop-responsive.css These three assets can be changed on the fly through an user-agent check on the server side, delivering the right UI to the right device. Within each of the assets, you can make fine adjustments for each subgroup of devices with media queries - for example, smart phones with different screen dimensions and pixel density. Having these three groups and the corresponding assets per group seem to be a good compromise between trying to put everything on a single set of assets - specially considering the constraints above - and going to the other side of the spectrum to create assets per discrete device (iPhone4, iPhone5, Nexus, S3, etc.). Keep in mind that these are my rules and are not in any shape or form a best practice - this is how it fits best for the scenarios I've been working with. If you need to use HTML tags on your page, surround them with af:group to protect the DOM structure For stretchable/fluid layouts: Use non-stretching containers: panelGroupLayout, panelBorderLayout, … panelBorderLayout can be used to approximate HTML table component To avoid multiple scroll bars, do not nest scrolling PanelGroupLayout components. Consider layout="vertical" For stretchable/fluid layouts: Most stretchable ADF components also work in flowing context with dimensionsFrom="auto" To stretch a component horizontally, use styleClass="AFStretchWidth" instead of "width:100%" Skinning Don't use CSS3 @media, @import, animations, etc. on skin css files. They will be removed. CSS3 properties within a class (box-shadow, transition, etc.) work just fine. Consider resetting some skin classes to better control their rendering: body {color: inherit;font: inherit;} af|document {-tr-inhibit: all;} af|commandLink {-tr-inhibit: all;} af|goLink {-tr-inhibit: all;} af|inputText::content {font: inherit;} Specific meta tags and CSS properties: Use <meta name="viewport" content="width=device-width, initial-scale=1.0, minimum-scale=1.0, maximum-scale=1.0"/> to avoid zooming (if you want) Use -webkit-overflow-scrolling: touch to enable native momentum scrolling within overflown areas (here) Use text-rendering: optmizeLegibility to improve readability. (here) User text-overflow: ellipsis to gracefully crop overflown text. (here) The meta-tags are included in each and every page in the metaContainer facet of af:document tag. You can also use a javascript to inject the meta-tags from the template. For the purpose of the example, I wanted to use as few workarounds as possible. The iPad template and sample application This sample application has been built as a WebCenter Portal application, but you will also be able to reuse the template and techniques on your vanilla ADF application. Keep in mind that I'm neither a designer nor a CSS specialist, so please don't bash me too much on the messy CSS file you'll find on the application. I've extended the provided PreferencesBean class that comes with WebCenter Portal and added code to dinamically change the template and skin on the fly. This is the sample application in landscape orientation: This is the sample application in portrait orientation - the left side menu hides automatically based on a CSS media query: Another screenshot with a skinned popup opened: This is a sample application for you to play with - ideally you shouldn't use it as a starting point. On the left side bar you will find links rendered from a WebCenter Portal navigation model - the link triggers a full request through an af:goLink, while the light blue PPR button triggers a PPR navigation. The dark blue toolbar buttons at the top don't have any function,while the Approve and Reject buttons show a skinned popup. The search box of course doesn't have any behavior attahed to it either. There's a known issue right now with some PPR calls that are randomly generating a 403 error redirecting to the login page - I didn't have time to investigate if this is iOS6 specific or not - if you have any insights please let me know your findings. You can download the sample here.

Recover Deleted Files on an NTFS Hard Drive from a Ubuntu Live CD

- by Trevor Bekolay

Accidentally deleting a file is a terrible feeling. Not being able to boot into Windows and undelete that file makes that even worse. Fortunately, you can recover deleted files on NTFS hard drives from an Ubuntu Live CD. To show this process, we created four files on the desktop of a Windows XP machine, and then deleted them. We then booted up the same machine with the bootable Ubuntu 9.10 USB Flash Drive that we created last week. Once Ubuntu 9.10 boots up, open a terminal by clicking Applications in the top left of the screen, and then selecting Accessories > Terminal. To undelete our files, we first need to identify the hard drive that we want to undelete from. In the terminal window, type in: sudo fdisk –l and press enter. What you’re looking for is a line that ends with HPSF/NTFS (under the heading System). In our case, the device is “/dev/sda1”. This may be slightly different for you, but it will still begin with /dev/. Note this device name. If you have more than one hard drive partition formatted as NTFS, then you may be able to identify the correct partition by the size. If you look at the second line of text in the screenshot above, it reads “Disk /dev/sda: 136.4 GB, …” This means that the hard drive that Ubuntu has named /dev/sda is 136.4 GB large. If your hard drives are of different size, then this information can help you track down the right device name to use. Alternatively, you can just try them all, though this can be time consuming for large hard drives. Now that you know the name Ubuntu has assigned to your hard drive, we’ll scan it to see what files we can uncover. In the terminal window, type: sudo ntfsundelete <HD name> and hit enter. In our case, the command is: sudo ntfsundelete /dev/sda1 The names of files that can recovered show up in the far right column. The percentage in the third column tells us how much of that file can be recovered. Three of the four files that we originally deleted are showing up in this list, even though we shut down the computer right after deleting the four files – so even in ideal cases, your files may not be recoverable. Nevertheless, we have three files that we can recover – two JPGs and an MPG. Note: ntfsundelete is immediately available in the Ubuntu 9.10 Live CD. If you are in a different version of Ubuntu, or for some other reason get an error when trying to use ntfsundelete, you can install it by entering “sudo apt-get install ntfsprogs” in a terminal window. To quickly recover the two JPGs, we will use the * wildcard to recover all of the files that end with .jpg. In the terminal window, enter sudo ntfsundelete <HD name> –u –m *.jpg which is, in our case, sudo ntfsundelete /dev/sda1 –u –m *.jpg The two files are recovered from the NTFS hard drive and saved in the current working directory of the terminal. By default, this is the home directory of the current user, though we are working in the Desktop folder. Note that the ntfsundelete program does not make any changes to the original NTFS hard drive. If you want to take those files and put them back in the NTFS hard drive, you will have to move them there after they are undeleted with ntfsundelete. Of course, you can also put them on your flash drive or open Firefox and email them to yourself – the sky’s the limit! We have one more file to undelete – our MPG. Note the first column on the far left. It contains a number, its Inode. Think of this as the file’s unique identifier. Note this number. To undelete a file by its Inode, enter the following in the terminal: sudo ntfsundelete <HD name> –u –i <Inode> In our case, this is: sudo ntfsundelete /dev/sda1 –u –i 14159 This recovers the file, along with an identifier that we don’t really care about. All three of our recoverable files are now recovered. However, Ubuntu lets us know visually that we can’t use these files yet. That’s because the ntfsundelete program saves the files as the “root” user, not the “ubuntu” user. We can verify this by typing the following in our terminal window: ls –l We want these three files to be owned by ubuntu, not root. To do this, enter the following in the terminal window: sudo chown ubuntu <Files> If the current folder has other files in it, you may not want to change their owner to ubuntu. However, in our case, we only have these three files in this folder, so we will use the * wildcard to change the owner of all three files. sudo chown ubuntu * The files now look normal, and we can do whatever we want with them. Hopefully you won’t need to use this tip, but if you do, ntfsundelete is a nice command-line utility. It doesn’t have a fancy GUI like many of the similar Windows programs, but it is a powerful tool that can recover your files quickly.

Win a place at a SQL Server Masterclass with Kimberly Tripp and Paul Randal

- by Testas

The top things YOU need to know about managing SQL Server - in one place, on one day - presented by two of the best SQL Server industry trainers!And you could be there courtesy of UK SQL Server User Group and SQL Server Magazine! This week the UK SQL Server User Group will provide you with details of how to win a place at this must see seminar You can also register for the seminar yourself at:www.regonline.co.uk/kimtrippsql More information about the seminar Where: Radisson Edwardian Heathrow Hotel, London When: Thursday 17th June 2010 This one-day MasterClass will focus on many of the top issues companies face when implementing and maintaining a SQL Server-based solution. In the case where a company has no dedicated DBA, IT managers sometimes struggle to keep the data tier performing well and the data available. This can be especially troublesome when the development team is unfamiliar with the affect application design choices have on database performance. The Microsoft SQL Server MasterClass 2010 is presented by Paul S. Randal and Kimberly L. Tripp, two of the most experienced and respected people in the SQL Server world. Together they have over 30 years combined experience working with SQL Server in the field, and on the SQL Server product team itself. This is a unique opportunity to hear them present at a UK event which will:· Debunk many of the ingrained misconceptions around SQL Server's behaviour · Show you disaster recovery techniques critical to preserving your company's life-blood - the data · Explain how a common application design pattern can wreak havoc in the database · Walk through the top-10 points to follow around operations and maintenance for a well-performing and available data tier! Please Note: Agenda may be subject to changeSessions AbstractsKEYNOTE: Bridging the Gap Between Development and Production Applications are commonly developed with little regard for how design choices will affect performance in production. This is often because developers don't realize the implications of their design on how SQL Server will be able to handle a high workload (e.g. blocking, fragmentation) and/or because there's no full-time trained DBA that can recognize production problems and help educate developers. The keynote sets the stage for the rest of the day. Discussing some of the issues that can arise, explaining how some can be avoided and highlighting some of the features in SQL 2008 that can help developers and DBAs make better use of SQL Server, and troubleshoot when things go wrong. SESSION ONE: SQL Server MythbustersIt's amazing how many myths and misconceptions have sprung up and persisted over the years about SQL Server - after many years helping people out on forums, newsgroups, and customer engagements, Paul and Kimberly have heard it all. Are there really non-logged operations? Can interrupting shrinks or rebuilds cause corruption? Can you override the server's MAXDOP setting? Will the server always do a table-scan to get a row count? Many myths lead to poor design choices and inappropriate maintenance practices so these are just a few of many, many myths that Paul and Kimberly will debunk in this fast-paced session on how SQL Server operates and should be managed and maintained. SESSION TWO: Database Recovery Techniques Demo-Fest Even if a company has a disaster recovery strategy in place, they need to practice to make sure that the plan will work when a disaster does strike. In this fast-paced demo session Paul and Kimberly will repeatedly do nasty things to databases and then show how they are recovered - demonstrating many techniques that can be used in production for disaster recovery. Not for the faint-hearted! SESSION THREE: GUIDs: Use, Abuse, and How To Move Forward Since the addition of the GUID (Microsoft’s implementation of the UUID), my life as a consultant and "tuner" has been busy. I’ve seen databases designed with GUID keys run fairly well with small workloads but completely fall over and fail because they just cannot scale. And, I know why GUIDs are chosen - it simplifies the handling of parent/child rows in your batches so you can reduce round-trips or avoid dealing with identity values. And, yes, sometimes it's even for distributed databases and/or security that GUIDs are chosen. I'm not entirely against ever using a GUID but overusing and abusing GUIDs just has to be stopped! Please, please, please let me give you better solutions and explanations on how to deal with your parent/child rows, round-trips and clustering keys! SESSION 4: Essential Database MaintenanceIn this session, Paul and Kimberly will run you through their top-ten database maintenance recommendations, with a lot of tips and tricks along the way. These are distilled from almost 30 years combined experience working with SQL Server customers and are geared towards making your databases more performant, more available, and more easily managed (to save you time!). Everything in this session will be practical and applicable to a wide variety of databases. Topics covered include: backups, shrinks, fragmentation, statistics, and much more! Focus will be on 2005 but we'll explain some of the key differences for 2000 and 2008 as well. Speaker Biographies Paul S.Randal Kimberley L. Tripp Paul and Kimberly are a husband-and-wife team who own and run SQLskills.com, a world-renowned SQL Server consulting and training company. They are both SQL Server MVPs and Microsoft Regional Directors, with over 30 years of combined experience on SQL Server. Paul worked on the SQL Server team for nine years in development and management roles, writing many of the DBCC commands, and ultimately with responsibility for core Storage Engine for SQL Server 2008. Paul writes extensively on his blog (SQLskills.com/blogs/Paul) and for TechNet Magazine, for which he is also a Contributing Editor.
