Preview of code-only WPF controls in VS2010 - how?

- by Christian

Hi, I hope I am able to illustrate the problem using a lot of images. First of all, I was no real fan of XAML (Silverlight issues, crashes in Preview, and so on...) Now, with VS2010 the situation has become better. There are still a lot of things I like better in code, but I also want a preview in my VS. So, take a look at the following control: It is really simple, a todo details list. The first screenshot shows the code of the control, pretty straighforward: There is no XAML, so obviously no preview. Of course, I could encapsulate it in another control, like shown in the next screenshot: But, in that case I have an additional file I do not want or need. So I had the idea to move the init stuff inside the contructor of a XAML control. For simplicity, I used simple elements. But they do not show up in the preview... Finally, I know I could use the controls in other parts of my app when creating UIs. But I am using layout manager, PRISM and a lot of other stuff, so I just want an easy preview of some specific control I created (without having to have a XAML wrapper file for each control) Thanks for help, and sorry for the post structure, but I though with images it is better to understand...

How to get a category listing from Magento?

- by alex

I want to create a page in Magento that shows a visual representation of the categories.. example CATEGORY product 1 product 2 ANOTHER CATEGORY product 3 My problem is, their database is organised very differently to what I've seen in the past. They have tables dedicated to data types like varchar, int, etc. I assume this is for performance or similiar. I haven't found a way to use MySQL to query the database and get a list of categories. I'd then like to match these categories to products, to get a listing of products for each category. Unfortunately Magento seems to make this very difficult. Also I have not found a method that will work from within a page block.. I have created showcase.phtml and put it in the XML layout and it displays and runs it's PHP code. I was hoping for something easy like looping through $this-getAllCategories(); and then a nested loop inside with something like $category-getChildProducts(); Can anyone help me? Thank you!

Why does the roll_out event fire in this code?

- by user339681

I have made this simple example to demonstrate some problems I'm having. <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"> <mx:Canvas id="buttonCanvas" x="100" y="100" opaqueBackground="#000000" width="80%" height="300" creationComplete="init(event)"> <mx:Button x="5" y="5"/> <mx:Button x="5" y="50"/> </mx:Canvas> <mx:Script> <![CDATA[ private function init(event:Event):void{ buttonCanvas.addEventListener(MouseEvent.ROLL_OUT, function(event:Event):void{ buttonCanvas.opaqueBackground=(buttonCanvas.opaqueBackground==0)? 0x666666:0; }); } ]]> </mx:Script> </mx:Application> I don't understand the following: Why doesn't the percentage nor absolute dimensions affect the canvas? Why does the roll_out event fire when the mouse leaves a button (even when it is still inside the canvas). I'm going nuts trying to figure this out. Any help would be greatly appreciated!

Setting the correct orientation for scrollbars in right-to-left pages.

- by Daniel Lew

I'm working with right-to-left layouts at the moment (think Hebrew or Arabic). In RTL, the page is generally flipped horizontally. However, I can't figure out how to change the orientation of the scrollbars. I would assume that the scrollbars should appear on the left side of a scrollable element, not the right side like it does in an LTR layout. Here is an example page where the scrollbar still appears on the right: <html dir="rtl"> <body> <div style="height: 100px; overflow: auto;"> <p>This is some text</p> <p>This is some text</p> <p>This is some text</p> <p>This is some text</p> <p>This is some text</p> </body> </html> Is the orientation of a scrollbar a browser locale setting, and thus is not something I should be concerned about, or is there a way to set the orientation of the scrollbar? (I'm not interested in implementing my own JavaScript scrollbar; if it turns out this is just a limitation of browsers then I'd rather live with that than add complexity to the page.)

How to reset keyboard for an entry field?

- by David.Chu.ca

I am using tag field as a flag for text fields text view fields for auto-jumping to the next field: - (BOOL)findNextEntryFieldAsResponder:(UIControl *)field { BOOL retVal = NO; for (UIView* aView in mEntryFields) { if (aView.tag == (field.tag + 1)) { [aView becomeFirstResponder]; retVal = YES; break; } } return retVal; } It works fine in terms of auto-jumping to the next field when Next key is pressed. However, my case is that the keyboards are different some fields. For example, one fields is numeric & punctuation, and the next one is default (alphabetic keys). For the numeric & punctuation keyboard is OK, but the next field will stay as the same layout. It requires user to press 123 to go back ABC keyboard. I am not sure if there is any way to reset the keyboard for a field as its keyboard defined in xib? Not sure if there is any APIs available? I guess I have to do something is the following delegate? -(void)textFieldDidBegingEditing:(UITextField*) textField { // reset to the keyboard to request specific keyboard view? .... } OK. I found a solution close to my case by slatvik: -(void) textFieldDidBeginEditing:(UITextField*) textField { textField.keyboardType = UIKeybardTypeAlphabet; } However, in the case of the previous text fields is numeric, the keyboard stays numeric when auto-jumped to the next field. Is there any way to set keyboard to alphabet mode?

Android: How to declare global variables?

- by niko

Hi, I am creating an application which requires login. I created the main and the login activity. In the main activity onCreate method I added the following condition: public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); ... loadSettings(); if(strSessionString == null) { login(); } ... } The onActivityResult method which is executed when the login form terminates looks like this: @Override public void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); switch(requestCode) { case(SHOW_SUBACTICITY_LOGIN): { if(resultCode == Activity.RESULT_OK) { strSessionString = data.getStringExtra(Login.SESSIONSTRING); connectionAvailable = true; strUsername = data.getStringExtra(Login.USERNAME); } } } The problem is the login form sometimes appears twice (the login() method is called twice) and also when the phone keyboard slides the login form appears again and I guess the problem is the variable strSessionString. Does anyone know how to set the variable global in order to avoid login form appearing after the user already successfully authenticates? Thanks!

how to run TimerTask off main UI thread?

- by huskyd97

I am having trouble with a TimerTask Interfering with In App Purchasing (Async Tasks). I am weak with Threads, so I believe it is running on the main UI thread, eating up resources. How can I run this outside the UI thread? I have searched, and tried some suggestions using handlers. but seems like I get the same result, app gets really laggy. when I don't run this task (refreshes every 500mS), the activity runs smoothly, and there are no hangs during In app purchases. Your help is appreciated, code snippet below: public class DummyButtonClickerActivity extends Activity { protected Timer timeTicker = new Timer("Ticker"); private Handler timerHandler = new Handler(); protected int timeTickDown = 20; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.mainhd); // start money earned timer handler TimerTask tick = new TimerTask() { public void run() { myTickTask(); } }; timeTicker.scheduleAtFixedRate(tick, 0, 500); // 500 ms each } // End OnCreate protected void myTickTask() { if (timeTickDown == 0) { /// run my code here //total = total + _Rate; timerHandler.post(doUpdateTimeout); } else if(timeTickDown < 0) { // do nothing } timeTickDown--; } private Runnable doUpdateTimeout = new Runnable() { public void run() { updateTimeout(); } }; private void updateTimeout() { // reset tick timeTickDown = 2; // 2* 500ms == once a second } }

How does an ASP.NET programmer go from working on/developing existing sites, to creating one from sc

- by SLC

I've been an ASP.NET developer for some time, always working on existing ASP.NET pages, modifying functionality, adding features, tweaking things etc. but have never built a site up from scratch. I've read books on ASP.NET, and they generally talk you through the various features of ASP.NET with a mock up site, but it's always very basic and they jump straight in. The time has come however, to write a site from scratch for a client. I've never done this before. There are design considerations, but like a lot of ASP.NET sites, the basic idea is, you have a site, where users can log in, and save some information like their name and password and address. The site has some functionality, but that's the basic design of a majority of (business-related) asp.net websites I would wager. I know how to program in ASP.NET already on an existing site, but I don't know how to design my own properly that meets the criteria above. I guess the main worry is security. I don't know the best way to handle a simple log-in system that stores user information like their name and password. I understand there are a few approaches to this, but the catch with this project is that it has to be absolutely bulletproof. Maximum security. All those good practices for security, it needs to have them all. I'm not asking what they are, but I am asking where to begin. What should be the first steps after I do File New Project ? Where can I look for information about setting up a secure ASP.NET website? I'll figure out the content and page layout later, it's the framework that is the big thing. Any and all advice would be welcome. I really want to get my first from-scratch project right from the beginning. Just to confuse things, it's possible I will be using MVC, I am not sure if this has any impact.

setImageViewResource Sometimes loads image and sometimes it doesn't.

- by Niv

Hi All, I'm writing a simple widget which has an imageview widget that is supposed to load an image dynamically. To do this, I'm starting a service in the onUpdate method of the service. I validated that the service is running, however, the image is loaded only once every 10 times. Here is the code: (In the Original extends AppWidgetProvider) @Override public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) { Log.d(LOG_TAG, "onUpdate(): Starting Service..1"); context.startService(new Intent(context, UpdateService.class)); } (The service:) @Override public void onStart(Intent intent, int startId) { Log.d(LOG_TAG, "(OnStart) In On Start..!"); AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(this); int[] appWidgetIds = appWidgetManager.getAppWidgetIds(new ComponentName(this, Original.class)); for (int appWidgetId : appWidgetIds) { RemoteViews remoteView = new RemoteViews(this.getPackageName(), R.layout.widget); remoteView.setImageViewResource(R.id.widgetImage, R.drawable.let02); remoteView.setTextViewText(R.id.widget_textview_month, "aaa"); Log.d(LOG_TAG, "(OnUpdate) Set All Fields!"); appWidgetManager.updateAppWidget(appWidgetId, remoteView); } //super.onStart(intent, startId); return; }

Android ProgressDialog inside another dialog

- by La bla bla

I'm working on a game using AndEngine, and I need to show the users the list of his Facebook friends. I've created my custom Adatper and after the loading finishes everything works great. I have a problem with the loading it self. The ListView is inside a custom dialog, since I don't really know how to create one using AndEngine, So inside this dialog, I'm running an AsyncTask to fetch the friends' info, in that AsyncTask I'm have a ProgressDialog. The problem is, the ProgressDialog shows up behind the dialog that contains the to-be list (which while loading, is just the title). I can see the ProgressDialog "peeking" behind that dialog.. Any Ideas? Here's some code: FriendsDialog.java private ProgressDialog dialog; //Constructor of the AsyncTask public FriendsLoader(Context context) { dialog = new ProgressDialog(context); dialog.setMessage("Please wait..\nLoading Friends List."); } @Override protected void onPreExecute() { dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); dialog.setView(inflater.inflate(R.layout.loading, null)); dialog.setMessage("Please wait..\nLoading friends."); dialog.show(); } @Override protected void onPostExecute(ArrayList<HashMap<String, Object>> data) { if (dialog.isShowing()) { dialog.dismiss(); } MyAdapter myAdapter = new MyAdapter(context, data); listView = (ListView) findViewById(R.id.list); listView.setAdapter(myAdapter); listView.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> myAdapter, View myView, int myItemInt, long mylng) { String id = (String) listView.getItemAtPosition(myItemInt); listener.onUserSelected(id); dismiss(); } }); }

Trouble managing events in Flex/actionscript

- by Zaka

Hello all, I'm doing some newbie tests, so I decided to capture the keyboard events to move a rectangle. But I don't get the desired result. Unless I click on the TextArea box, I'm not able to capture the event key code. After that, all goes pretty well. I'm using Eclipse 3.3 + Flex 3.0 on Linux. Here's my code: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" enterFrame="enterFrame(event)" keyDown="onKeyDown(event)"> <mx:TextArea id="myText" x="200" y="200" width="100" height="100" /> <mx:Canvas id="myCanvas" x="0" y="0" width="100" height="100" /> <mx:Script> <![CDATA[ public var clearColor : uint = 0xFF456798; public var myPoint : Point = new Point(0,0); public function enterFrame(event:Event):void { myCanvas.graphics.clear(); myCanvas.graphics.beginFill(0xFF344ff0); myCanvas.graphics.drawRect(myPoint.x,myPoint.y,40,40); myCanvas.graphics.endFill(); } public function onKeyDown(event:KeyboardEvent):void { myText.text = "Keycode is: " + event.keyCode + "\n"; switch(event.keyCode) { case 37: //Left myPoint.x -= 1; break; case 38: //Up myPoint.y -= 1; break; case 39: //Right myPoint.x += 1; break; case 40: //Down myPoint.y += 1; break; } } ]]> </mx:Script> </mx:Application>

Facebook call back function with timeout

- by Dirty Bird Design

So I've been getting my ass kicked pretty good with Facebook's moving target of an API. I need to display some hidden content after a person clicks 'like' on a landing page. I can somewhat get this to work, when the user clicks 'like' the normal fb dialogue appears and then goes away immediately and content is displayed. I have 'achieved' this with the following js. <script> FB.Event.subscribe('edge.create', function(href, widget) { document.getElementById('goodies').style.display = "block"; document.getElementById('fb-content').style.display= "block"; document.getElementById('copy').style.display = "none"; }); </script> I cannot find any documentation about a callback event after someone hits "post to facebook" or after the dialogue closes, only afte they hit like. How would I incorporate a setTimeout function into this to give people some time to fill out the fb dialogue? thanks. If anyone has a better way to do this I'm all ears. This is for a business page and I cannot seem to add an app to get an app ID anymore so the API is pretty useless to me at this point. Also, if the url to be liked is a fb page, the callbacks don't seem to fire. Other code used: <html xmlns:fb="http://ogp.me/ns/fb#"> <div id="fb-root"></div> <script>(function(d, s, id) { var js, fjs = d.getElementsByTagName(s)[0]; if (d.getElementById(id)) return; js = d.createElement(s); js.id = id; js.src = "//connect.facebook.net/en_US/all.js#xfbml=1"; fjs.parentNode.insertBefore(js, fjs); }(document, 'script', 'facebook-jssdk')); </script> <fb:like href="onlynonfburl.com" send="false" layout="button_count" width="450" show_faces="false" font="arial"></fb:like>

Defining EditText imeOptions when using InputMethodManager.showSoftInput(View, int, ResultReceiver)

- by TuomasR

In my application I have a custom view which requires some text input. As the view in itself doesn't contain any actual views (it's a Surface with custom drawing being done), I have a FrameLayout which contains the custom view and underneath it an EditText -view. When the user does a specific action, the custom view is hidden and the EditText takes over for user input. This works fine, but android:imeOptions seem to be ignored for this view. I'm currently doing this: InputMethodManager inputMethodManager = (InputMethodManager)parent.getSystemService(Context.INPUT_METHOD_SERVICE); EditText t = (EditText)parent.findViewById(R.id.DummyEditor); t.setImeOptions(EditorInfo.IME_ACTION_DONE); inputMethodManager.showSoftInput(t, 0, new ResultReceiver(mHandler) { @Override protected void onReceiveResult( int resultCode, Bundle resultData) { // We're done System.out.println("Editing done : " + ((EditText)parent.findViewById(R.id.DummyEditor)).getText()); } } ); It seems that the setImeOptions(EditorInfo.IME_ACTION_DONE) has no effect. I've also tried adding the option to the layout XML with android:imeOptions="actionDone". No help. Any ideas?

How to override jquery's show() and hide() functions

- by Max Williams

hi all Short version of question: see title Long version of question: I've used jquery's show() and hide() functions extensively in my code and just encountered a bit of a problem: they work by changing the display attribute of the element to 'block' or 'none' respectively, so that if you have somethin that has display: inline and then hide and show it, you've changed its display to block, which screws up the layout in a couple of cases. In my code, whenever i want something to be hidden initially i give it a class 'hidden'. This class is simply {display: none}. I'd like the change show and hide to remove or add this class, instead of directly changing the display attribute, so that if you add the hidden class and then remove it again (ie hide and show something) then it's back to exactly how it was to start off with (since adding a class overrides the attributes rather than directly changing them). Something like this (this is a little pseucodey as i don't know how to set the function up properly - let's assume that 'this' is the object that show/hide was called on) function show(){ this.removeClass("hidden"); } function hide(){ this.addClass("hidden"); } how and where would i go about overriding the jquery methods? (I'm not a javascript expert) thanks - max

Switching Between Cards in a CardLayout using getParent()

- by plutoisaplanet

Hey everyone, I am writing an application where I am using the CardLayout to swap between two panels that are placed right on top of one another. There's a JPanel called Top, and it's layout is the CardLayout. Inside this JPanel is a JPanel called CMatch. Whenever the user clicks the submit button in the CMatch panel, I want a new JPanel added to Top that is custom built based on what the user types in, and it will be shown instead of the original CMatch panel. All of this done using the CardLayout. These are all different classes in different files, however (the panel Top with CardLayout, the panel CMatch that is inside the Top panel, and the custom built panel). So i tried using the following to add the new panel to the Top panel and then have it shown: (this code takes place in the CMatch class): private void submitButtionActionPerformed(ActionEvent e) { CardLayout cl = (CardLayout)(this.getParent().getLayout()); cl.addLayoutComponent(new CChoice(), "college_choices"); cl.show(this.getParent(), "college_choices"); } However, this didn't work. So i was wondering, what am I doing wrong? Any advice is greatly appreciated, thanks!

CSS file in a Spring WAR returns a 404

- by Rachel G.

I have a J2EE application that I am building with Spring and Maven. It has the usual project structure. Here is a bit of the hierarchy. MyApplication src main webapp WEB-INF layout header.jsp styles main.css I want to include that CSS file in my JSP. I have the following tag in place. <c:url var="styleSheetUrl" value="/styles/main.css" /> <link rel="stylesheet" href="${styleSheetUrl}"> When I deploy the application, the CSS page isn't being located. When I view the page source, the href is /MyApplication/styles/main.css. Looking inside the WAR, there is a /styles/main.css. However, I get a 404 when I try to access the CSS file directly in the browser. I discovered that the reason for the issue was the Dispatcher Servlet mapping. The mapping looks as follows. <servlet-mapping> <servlet-name>Spring MVC Dispatcher Servlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> I imagine the Dispatcher Servlet doesn't know how to handle the CSS request. What is the best way to handle this issue? I would rather not have to change all of my request mappings.

Android - update widget text

Hi, i have 2 questions about widgets update I have 2 buttons and i need to change one button text when i press the other one, how can i do this? The first time i open the widget it calls the onUpdate method, but it never calls it again. I need to update the widget every 2 seconds and i have this line in the xml. android:updatePeriodMillis="2000" Do i need a service or should it works just with the updatePeriodMillis tag? onUpdate method RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.newswidget); Intent intent = new Intent(context, DetalleConsulta.class); intent.putExtra(DetalleConsulta.CONSULTA_ID_NAME, "3"); PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0); views.setOnClickPendingIntent(R.id.btNews, pendingIntent); /* Inicializa variables para llamar el controlador */ this.imei = ((TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE)).getDeviceId(); this.controlador = new Controlador(this.imei); try { this.respuestas = this.controlador.recuperarNuevasRespuestas(); if(this.respuestas != null && this.respuestas.size() > 0){ Iterator<Consulta> iterRespuestas = this.respuestas.iterator(); views.setTextViewText(R.id.btNews, ((Consulta)iterRespuestas.next()).getRespuesta()); } } catch (PersistenciaException e) { //TODO manejar error } appWidgetManager.updateAppWidget(appWidgetIds, views); thx a lot!!!

highlight listview items android

When I populate the list I have to check a boolean in the object I'm populating the listview and if it is true to change the background color of that row. public View getView(int position, View convertView, ViewGroup parent) { LoginsList entry = listOfLoginsLists.get(position); if (convertView == null) { LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); convertView = inflater.inflate(R.layout.lists_row, null); } TextView ListName = (TextView) convertView.findViewById(R.id.tvListName); ListName.setText(entry.getListName()); TextView ListDescription = (TextView) convertView.findViewById(R.id.tvListDescription); ListDescription.setText(entry.getListDescription()); Button Send = (Button) convertView.findViewById(R.id.bSend); Send.setOnClickListener(this); Send.setTag(entry); RelativeLayout RelLayout = (RelativeLayout) convertView.findViewById(R.id.layoutListsRow); RelLayout.setFocusableInTouchMode(false); RelLayout.setFocusable(false); RelLayout.setOnClickListener(this); RelLayout.setTag(entry); if (entry.isSent()) { RelLayout.setBackgroundColor(Color.parseColor("#4400FF00")); } return convertView; } But this code doesn't work right.

How to create two columns on a web page?

- by Roman

I want to have two columns on my web page. For me the simples way to do that is to use a table: <table> <tr> <td> Content of the first column. </td> <td> Content of the second column. </td> </tr> </table> I like this solution because, first of all, it works (it gives exactly what I want), it is also really simple and stable (I will always have two columns, no matter how big is my window). It is easy to control the size and position of the table. However, I know that people do not like the table-layout and, as far as I know, they use div and css instead. So, I would like also to try this approach. Can anybody help me with that? I would like to have a simple solution (without tricks) that is easy to remember. It also needs to be stable (so that it will not accidentally happen that one column is under another one or they overlap or something like that).

Structuring iPhone/iPad application views

- by Mark

I have an idea about an application that I want to build and Im new to iPhone/iPad development (but not new to development in other languages/frameworks such as .NET and Java). I want to layout some views on the screen so that they animate (slide in) from different directions into their places. The question is about the strucuture of the application, if I have say 4 rectanglular areas on the screen that contain business data, such as contacts (name, photo, etc...) and they all take up different widths of the screen (say the first contact takes up one row of the screen, but the next 2 take up half the width of the next row each, and so on). Should I create a custom view for the different sized contact views, (i.e. LargeCustomView and SmallCustomView, and any other special type that I make) or should it all be one type, say, CustomerDetailsView which could be stretched to fit at design time? Also, if there were, say, 3 different instances of the same custom view on the one screen, are there 3 instances of the view controller also? Im a little confused about powering the data behind a view, can someone shed some light on this for me? Do I just set the properties (say an instance variable ContactForView) on the view controller for each instance? Thanks for any help you can give Cheers, Mark
