• Graphics trouble after resuming from hibernate or suspend

  - by Voyagerfan5761

  I have a Dell Inspiron 2650 (with NVidia graphics, using nouveau drivers) that I'm using to try out Ubuntu. It's all great, except that Hibernate and Suspend aren't usable. Yes, I know that questions about power-save issues are rampant in the Linux support universe, but it seems that every time I find a solution it's for a very specific hardware combination and doesn't apply to me. So anyway, here goes. When I resume from either power-saving mode, I'll get graphics problems anywhere on the range from a few scattered random-colored pixels that won't change; all the way to full-screen patterns that don't change as I move the mouse, hit keys on the keyboard, or even bring up the shutdown dialog using the power button. Those full-screen issues (which may involve stripes with random pixels, partial black screen, or both) always end in me forcing the machine to shut down by holding the power button. I haven't done much testing yet to determine what severity level is most commonly associated with each mode, but I do avoid using either power-save option because of these issues. I'll add info on my hardware as I can gather it (no home internet connection, and this laptop is tethered to my desk by a dead battery and casing degradation). Please feel free to request something specific in the question comments. Hardware Info See this hardinfo report for my system's hardware configuration. (No, my username is not "myuser"; I sanitized hardinfo's output before publishing it.) Screenshots These screenshots are from a relatively mild occurrence, which happened after the second hibernation I took that session. The first one worked great, though I used the wireless card and Firefox heavily between the two hibernation attempts. Take a look at what happened when I opened my home directory in Nautilus and scrolled it: See below for the situations I've tested so far. The real trouble comes when the machine resumes to an unusable state; in such cases I can't even unlock the screen or properly reboot, much less take a screenshot. I have a hunch that putting a CD in the drive will cause such major failures, and I will try that at some point; see related question. Situations Tested Maverick (10.10) Suspend Seems to suspend nicely with nothing running Seems to suspend nicely with flash drive plugged in On resume from suspend with no flash drive, Terminal and gedit running: Funky graphics on top of log output, then blank screen with pixelated cursor; no response to power button (normally will shutdown 60 seconds later) Hibernate Seems to hibernate nicely with nothing running Seems to hibernate nicely with a few apps (Terminal, Mouse preferences) running Seems to not hibernate when flash drive plugged in Seems to not hibernate when System Monitor is running Have encountered failed hibernation (after several hours and one successful hibernate/thaw cycle) with no external media connected and no programs running except normal background stuff Natty LiveCD (11.04_2010-12-22) When I tested it, Natty wouldn't stay logged in. It played part of the login sound and then [ OK ] appeared in the top right corner (white-on-black terminal text) for a few seconds. Then it kicked me back to the Unlock screen. It did that four times before I gave up and just tested suspend from the Unlock screen. Suspend Resumed to vertical gray and black lines 2px (?) wide, then shifted to vertical "jail bars" of black over a black screen with above-described random pixels and mouse pointer. No apparent response to input from mouse (clicking randomly). Keyboard and touchpad unrecognized.

• WF4 &ndash; Guess the number game!

  - by MarkPearl

  I posted yesterday how really good WF4 was looking. Today I thought I would show some real basics that I was able to figure out. This will be a simple example, I am going to make a flowchart workflow – which will prompt the user to guess the number until they guess the right number. Lets begin… Make a new project and make it a Workflow console Application. Then select the Workflow file and drag a FlowChart (2) to point 3. This will now show a green start circle in the designer form. We are going to work with primitives to start with. We are now going to drag a few objects onto the Workflow, We drag the WriteLine, Assign & Decision items onto the designer. Once they are dragged onto the designer we will want to link them up. The order that they are linked is critical since this will determine the order of the solution. In this case, we want the system to first ask “Guess a number”, then to wait for the user to input some code, and then to display “You got it” if they got it right, and “Try again” if they got it wrong. So we now link the arrows to the objects. This is done by moving the mouse pointer over the start objects and clicking on one of the toggles and then dragging it to the next object and releasing the button over one of the toggles. This will place an arrow from the source object to the target object. Okay… pretty simple stuff – now we just need these primitive objects to do stuff. Lets start with the WriteLine primitive. We place the text in inverted commas in the Text field. Because this field accepts any valid VB expression we could have put variables etc. in there if we wanted to. The next thing we want to do is allow the user to input a number. This brings up an interesting problem, if a user were to type in a number, there would need to be someway to declare a variable to hold that value for the life of the workflow. We can achieve this by declaring a variable. To declare a variable, move your cursor over the variables tab at the bottom of the workflow, and then type the name of the new variable in the “Create Variable” field and set it as shown in the image above. Now that we have a variable, we want to call the Console.Readline method and assign the inputted value from the Console to that variable. The code that cannot be seen is actually this – Convert.ToInt32(Console.ReadLine()) We now have a workflow that first prompts the user for a number, then allows the user to type in a number. We are almost done, we just need to make the system react to the value inputted. There are a few ways we could do this, I am going to use the Decision item. So select the Decision object on the designer and then view its properties (F4 for me), and in the condition field place a condition. For simplicity sake I have decided that if the user guesses 10, they will have guessed the number. This is now the completed workflow. Its really easy to understand and shows some really powerful principles for Business applications. You can run the application and see what it does. Imagine writing business solutions that do not worry about the exact flow of objects, but simply allows a business analyst or someone to configure the solution to work exactly as the business rules would dictate. And if the rules changed six months later all they would need to do is re-drag some of the flows. Now I do not know if WF4 will allow for this, but it feels like it is a step in the right direct.

• HTML, JavaScript, and CSS in a NetBeans Platform Application

  - by Geertjan

  I broke down the code I used yesterday, to its absolute bare minimum, and then realized I'm not using HTML 5 at all: <html> <head> <link rel="stylesheet" href="style.css" type="text/css" media="all" /> <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.3/jquery.min.js"></script> <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.16/jquery-ui.min.js"></script> <script type="text/javascript" src="script.js"></script> </head> <body> <div id="logo"> </div> <div id="infobox"> <h2 id="statustext"/> </div> </body> </html> Here's the script.js file referred to above: $(function(){ var banana = $("#logo"); var statustext = $("#statustext"); var defaulttxt = "Drag the banana!"; var dragtxt = "Dragging the banana!"; statustext.text(defaulttxt); banana.draggable({ drag: function(event, ui){ statustext.text(dragtxt); }, stop: function(event, ui){ statustext.text(defaulttxt); } }); }); And here's the stylesheet: body { background:#3B4D61 repeat 0 0; margin:0; padding:0; } h2 { color:#D1D8DF; display:block; font:bold 15px/10px Tahoma, Helvetica, Arial, Sans-Serif; text-align:center; } #infobox { position:absolute; width:300px; bottom:20px; left:50%; margin-left:-150px; padding:0 20px; background:rgba(0,0,0,0.5); -webkit-border-radius:15px; -moz-border-radius:15px; border-radius:15px; z-index:999; } #logo { position:absolute; width:450px; height:150px; top:40%; left: 30%; background:url(bananas.png) no-repeat 0 0; cursor:move; z-index:700; } However, I've replaced the content of the HTML file with a few of the samples from here, without any problem; in other words, if the HTML 5 canvas were to be needed, it could seamlessly be incorporated into my NetBeans Platform application: https://developer.mozilla.org/en/Canvas_tutorial/Basic_usage

• Direct3D - Zooming into Mouse Position

  - by roohan

  I'm trying to implement my camera class for a simulation. But I cant figure out how to zoom into my world based on the mouse position. I mean the object under the mouse cursor should remain at the same screen position. My zooming looks like this: VOID ZoomIn(D3DXMATRIX& WorldMatrix, FLOAT const& MouseX, FLOAT const& MouseY) { this->Position.z = this->Position.z * 0.9f; D3DXMatrixLookAtLH(&this->ViewMatrix, &this->Position, &this->Target, &this->UpDirection); } I passed the world matrix to the function because I had the idea to move my drawing origin according to the mouse position. But I cant find out how to calculate the offset in to move my drawing origin. Anyone got an idea how to calculate this? Thanks in advance. SOLVED Ok I solved my problem. Here is the code if anyone is interested: VOID CAMERA2D::ZoomIn(FLOAT const& MouseX, FLOAT const& MouseY) { // Get the setting of the current view port. D3DVIEWPORT9 ViewPort; this->Direct3DDevice->GetViewport(&ViewPort); // Convert the screen coordinates of the mouse to world space coordinates. D3DXVECTOR3 VectorOne; D3DXVECTOR3 VectorTwo; D3DXVec3Unproject(&VectorOne, &D3DXVECTOR3(MouseX, MouseY, 0.0f), &ViewPort, &this->ProjectionMatrix, &this->ViewMatrix, &WorldMatrix); D3DXVec3Unproject(&VectorTwo, &D3DXVECTOR3(MouseX, MouseY, 1.0f), &ViewPort, &this->ProjectionMatrix, &this->ViewMatrix, &WorldMatrix); // Calculate the resulting vector components. float WorldZ = 0.0f; float WorldX = ((WorldZ - VectorOne.z) * (VectorTwo.x - VectorOne.x)) / (VectorTwo.z - VectorOne.z) + VectorOne.x; float WorldY = ((WorldZ - VectorOne.z) * (VectorTwo.y - VectorOne.y)) / (VectorTwo.z - VectorOne.z) + VectorOne.y; // Move the camera into the screen. this->Position.z = this->Position.z * 0.9f; D3DXMatrixLookAtLH(&this->ViewMatrix, &this->Position, &this->Target, &this->UpDirection); // Calculate the world space vector again based on the new view matrix, D3DXVec3Unproject(&VectorOne, &D3DXVECTOR3(MouseX, MouseY, 0.0f), &ViewPort, &this->ProjectionMatrix, &this->ViewMatrix, &WorldMatrix); D3DXVec3Unproject(&VectorTwo, &D3DXVECTOR3(MouseX, MouseY, 1.0f), &ViewPort, &this->ProjectionMatrix, &this->ViewMatrix, &WorldMatrix); // Calculate the resulting vector components. float WorldZ2 = 0.0f; float WorldX2 = ((WorldZ2 - VectorOne.z) * (VectorTwo.x - VectorOne.x)) / (VectorTwo.z - VectorOne.z) + VectorOne.x; float WorldY2 = ((WorldZ2 - VectorOne.z) * (VectorTwo.y - VectorOne.y)) / (VectorTwo.z - VectorOne.z) + VectorOne.y; // Create a temporary translation matrix for calculating the origin offset. D3DXMATRIX TranslationMatrix; D3DXMatrixIdentity(&TranslationMatrix); // Calculate the origin offset. D3DXMatrixTranslation(&TranslationMatrix, WorldX2 - WorldX, WorldY2 - WorldY, 0.0f); // At the offset to the cameras world matrix. this->WorldMatrix = this->WorldMatrix * TranslationMatrix; } Maybe someone has even a better solution than mine.

• Data Mining Email with Thunderbird

  - by user554629

  Oracle has many formal, searchable locations:  Service Requests, BugIDs, Technical Documents. These contain the results of an investigation for a customer crash situation;  they're created after the intense work of resolution is over, and typically contain the "root cause" of the failure ... but not the methods for identifying that cause. Email is still the standby for interacting with quickly formed groups of specialists, focusing on a particular incident.Customer BI, Network and System specialists;  Oracle Tech Support, Development, Consultants; OEM Database, OS technical support.   It is a chaotic, time-oriented set of configuration, call stacks, changes, techniques to discover and repair the failure. I needed to organize that information into something cohesive to prepare the blog entry on Teradata.  My corporate email client of choice is Thunderbird.   My original (flawed) search technique: R-Click on Inbox in Thunderbird left pane, and choose Search Messages Subject:  [ teradata ] Results: A new window titled "Search Messages"Single pane of selected messagesColumn headings:  Subject  From  Date  LocationNo preview window for messages There are 673 email entries in the result ( too many )  R-click icon just above the vertical scroll bar on the rightCheck [x] Tags Click on the Tags header to sort by "Important" View contents of message by double-clickingOpens in the Thunderbird Main Window in a new Tab Not what I was looking for, close the tab and try again. There has to be a better way.  ( and there is ) I need to be more productive, eliminating duplicate-chained messages, for example.   Even the Tag "Important" that was added during the investigation phase, is "not so much" for my current task. In the "Search Messages" window, click [ Save as Search Folder ] [ teradata ]  Appears as a new folder in my Inbox. Focus on that folder and the results appear with a list of messages like every other folder in the Inbox.Only the results of the search are shown A preview window is now available for each message Sort, Select message, Cursor Down ... navigates quickly through the messages. But wait, there's more ... Click Find ( Ctrl-F) Enter a search term for the message body, like.[ LIBPATH ] The search is "sticky" ... each message you cycle through wil focus ( and highlight) the LIBPATH search term. And still more .... Reset the Tag"Important" message.   Press "1" and the tag is removed Press "4" and a new Tag "ToDo" is applied After applying all of the tags, sort by Tag for a new message order Adjust the search criteria ... R-click on the [ teradata ] search folder, and choose Properties Add additional criteria to narrow the search Some of the information I'm looking for did not contain "teradata" in the subject line. + Body  [ contains ] [ Best Practices ] That's it.  Much more efficient search.   Thank you Thunderbird.

• SSMS Tools Pack 2.7 is released. New website, improved licensing and features.

  - by Mladen Prajdic

  New website Nice, isn't it? Cleaner, simpler, better looking and more modern. If you have any suggestions for further improvements I'd be glad to hear them. Simpler licensing With SSMS tools Pack 2.7 the licensing is finally where it should be. It is now based on the activate/deactivate model. This way you can move a license from machine to machine with simple deactivation on one and reactivation on another machine. Much better, no? Because of very good feedback I have added an option for 6 machines and lowered the 4 machines option to 3 machines. This should make it much simpler for you to choose the right option for yourself. Improved features Version 2.5.3 was already extremely stable and 2.7 continues with that tradition. Because of that I could fully focus on features and why 3.0 will rock even more that 2.7! ;) In version 2.7 I have addressed quite a few improvements you were requesting for a while now. SQL History This is probably the biggest time saver out there, therefore it's only fair it gets a few important updates. If you have an existing .sql file opened, the Window Content History now saves your code to that existing file and also makes a backup in the SQL History log default location. Search is still done through the SQL History log but the Tab Sessions Restore opens your existing .sql file. This way you don't have to remember to save your existing files by yourself anymore. A bug when you couldn't search properly if you copied the log files to a new location was fixed. Unfortunately this removed the option to filter a search with the time component. The smallest search interval is now one day. The SSMS Tools Pack now remembers the visibility of the Current Window History window when you exit SSMS. SQL Snippets You can now set the position of the cursor in your snippets by placing {C} somewhere in your snippet. It's a small improvement but can be a huge time saver since you don't have to move through the snippet to the desired location anymore. Run script on multiple databases Database choices can now be saved with a name and then loaded again next time. You can also choose to run the script in a new window for each chosen database. Search through grid results You can now go previous/next search result with the Prev/Next control inside the search window. This is extremely useful if you have a large resultset. IT saves you the scrolling. CRUD generator Four new variables have been added: |CurrentDate| writes current date in format yyyy-MM-dd to your script |CurrentTime| writes current time in 24h format HH:mm:ss to your script |CurrentWinUser| writes current Windows logged on user to your script |CurrentSqlUser| writes current SQL logged on login to your script This was actually quite a requested feature so if you have any other ideas for extra variables, do let me know. That's about it. I hope you're going to enjoy this version as much as the previous ones. Have fun!

• How to get the height of an image and apply that height to a div? [migrated]

  - by Mick79

  I am building a mobile web app and I'm using jquerytools slider on it. i want te slider to show (in proper ratio) across all mobile devices so width of the images is 100% and height is auto in css. However as all the elements are floated and jquerytools slider requires the position be set to absolute, the containing div (#header) doesn't stretch to fit the content. I am trying to use jquery to get the height of the height of the img and apply that height to the header.... however I am having no luck. CSS: #header{ width:100%; position:relative; z-index: 20; /* box-shadow: 0 0 10px white; */ overflow: auto; } .scrollable { position:relative; overflow:hidden; width: 100%; height: 100%; /* box-shadow: 0 0 20px purple; */ /* height:198px; */ z-index: 20; overflow: auto; } .scrollable .items { /* this cannot be too large */ width:1000%; position:absolute; clear:both; /* box-shadow: 0 0 30px green; */ } .items div { float:left; width:10%; height:100%; } /* single scrollable item */ .scrollable img { /* float:left; */ width:100%; height: auto; /* height:198px; */ } /* active item */ .scrollable .active { border:2px solid #000; position:relative; cursor:default; } HTML <div id=header><!-- root element for scrollable --> <div class="scrollable" id="scrollable"> <!-- root element for the items --> <div class="items"> <div> <img src="img/img2.jpg" /> </div> <div> <img src="img/img1.jpg" /> </div> <div> <img src="img/img3.jpg" /> </div> <div> <img src="img/img4.jpg" /> </div> <div> <img src="img/img6.jpg" /> </div> </div><!-- items --> </div><!-- scrollable --> </div><!-- header -->

• iptables to allow 80 and 443 on chillispot running ddwrt

  I am having problems setting this up. this is what I am trying to do. I have Chillispot (hotpsot) running on dd-wrt. Everything is setup, but the client wants only 80 and 443 to go through through the hotspot. I found this tutorial for dd-wrt but that doesnt seem to work. http://www.dd-wrt.com/wiki/index.php/Iptables#Allow_HTTP_traffic_only_to_specific_domain.28s.29 Initially I tried to place the options at the top but didnt work. then i flushed the iptables and set only these three.

• Android ListView with SQLite

  - by soclose

  Hi I'd like to refresh the Listview items. These items are populated from SQLite database. My code is below public class Weeve extends Activity { private String[] lv_arr; protected ListView CView; private DBAdapter mDbHelper; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); mDbHelper = new DBAdapter(this); mDbHelper.open(); Cursor c = mDbHelper.getAll(); if (c.getCount() > 0) {if (c.moveToFirst()) { ArrayList strings = new ArrayList(); do { String mC = c.getString(0); strings.add(mC); } while (c.moveToNext()); lv_arr = (String[]) strings.toArray(new String[strings.size()]); } } else Toast.makeText(this, "No more Records", Toast.LENGTH_SHORT).show(); c.close(); ListView CView = new ListView(this); CView.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, lv_arr)); setContentView(CView);}} I'd like to make refreshing this list view after adding, updating or deleting SQLite table. These operations are called by content or option menu. I tried to create these code into a separated function and call it after every operation. But can't. I think setContentView(CView) statement. I also tried to use SimpleCursorAdapter like notepad sample from Android.com. I got Thread error. Help me.

• How * tag can be used in CSS?

  - by php html

  I'm trying to understand how a background image is used in a css button. It seems the image is much larger than the button, still the corners are matched to the button(resulting a rounded corner button). It seems it is related to .btn *. I couldn't find any reference about how * can be used. Can you explain how the image is rendered in the button, using the * tag? I assume * will match any element. However I don't get it how in this case the image is rendered like this. .btn { display: block; position: relative; background: #aaa; padding: 5px; float: left; color: #fff; text-decoration: none; cursor: pointer; } .btn * { font-style: normal; background-image: url(btn2.png); background-repeat: no-repeat; display: block; position: relative; } full example here: http://monc.se/kitchen/59/scalable-css-buttons-using-png-and-background-colors/

• converting 2D mouse coordinates to 3D space in OpenGL ES

  - by Jayesh

  I want to convert mouse's current X and Y coordinates into the 3D space I have drawn in the viewport. I need to do this on the OpenGL ES platform. I found following possible solutions implemented in OpenGL, but none fits what I am looking for. I found NeHe's tutorial on doing exactly this, but in traditional OpenGL way. It uses gluUnProject. http://nehe.gamedev.net/data/articles/article.asp?article=13 Although gluUnProject is not available in OpenGL ES, its implementation seems simple enough to port back. But before calling it, we need to call glReadPixels with GL_DEPTH_COMPONENT and that is not possible in OpenGL ES. (The reason I found in this thread: http://www.khronos.org/message_boards/viewtopic.php?f=4&t=771) What I want to do is similar to picking, except that I don't want to select the object but I want exact coordinates so that I can recognize particular portion of the object that is currently under mouse cursor. I went through the Picking tutorials in this answer. http://stackoverflow.com/posts/2211312/revisions But they need glRenderMode, which I believe is absent in OpenGL ES. If you know how to solve this problem in OpenGL ES, please let me know. Thanks.

• Cannot get Correct month for a call from call log history

  - by Nishant Kumar

  I am trying to extract information from the call log of the android. I am getting the call date that is one month back from the actual time of call. I mean to say that the information extracted by my code for the date of call is one mont back than the actual call date. I have the following in the Emulator: I saved a contact. Then I made a call to the contact. Code: I have 3 ways of extracting call Date information but getting the same wrong result. My code is as follows: /* Make the query to call log content */ Cursor callLogResult = context.getContentResolver().query( CallLog.Calls.CONTENT_URI, null, null, null, null); int columnIndex = callLogResult.getColumnIndex(Calls.DATE); Long timeInResult = callLogResult.getLong(columnIndex); /* Method 1 to change the milliseconds obtained to the readable date formate */ Time time = new Time(); time.toMillis(true); time.set(timeInResult); String callDate= time.monthDay+"-"+time.month+"-"+time.year; /* Method 2 for extracting the date from tha value read from the column */ Calendar calendar = Calendar.getInstance(); calendar.setTimeInMillis(time); String Month = calendar.get(Calendar.MONTH) ; /* Method 3 for extracting date from the result obtained */ Date date = new Date(timeInResult); String mont = date.getMonth() While using the Calendar method , I also tried to set the DayLight SAving Offset but it didnot worked, calendar.setTimeZone(TimeZone.getTimeZone("Europe/Paris")); int DST_OFFSET = calendar.get( Calendar.DST_OFFSET ); // DST_OFFSET Boolean isSet = calendar.getTimeZone().useDaylightTime(); if(isSet) calendar.set(Calendar.DST_OFFSET , 0); int reCheck = calendar.get(Calendar.DST_OFFSET ); But the value is not set to 0 in recheck. I am getting the wrong month value by using this also. Please some one help me where I am wrong? or is this the error in emulator ?? Thanks, Nishant Kumar Engineering Student

• Scrollbar problem with jquery ui dialog in Chrome and Safari

  - by alexis.kennedy

  I'm using the jquery ui dialog with modal=true. In Chrome and Safari, this disables scrolling via the scroll bar and cursor keys (scrolling with the mouse wheel and page up/down still works). This is a problem if the dialog is too tall to fit on one page - users on a laptop get frustrated. Someone raised this three months ago on the jquery bug tracker - http://dev.jqueryui.com/ticket/4671 - it doesn't look like fixing it is a priority. :) So does anyone (i) have a fix for this? (ii) have a suggested workaround that would give a decent usability experience? I'm experimenting with mouseover / scrollto on bits of the form, but it's not a great solution :( EDIT: props to Rowan Beentje (who's not on SO afaict) for finding a solution to this. jQueryUI prevents scrolling by capturing the mouseup / mousedown events. So this: $("dialogId").dialog({ open: function(event, ui) { window.setTimeout(function() { jQuery(document) .unbind('mousedown.dialog-overlay') .unbind('mouseup.dialog-overlay') ; }, 100); }, modal: true}); seems to fix it. Use at own risk, I don't know what other unmodal behaviour unbinding this stuff might allow.

• Implementing a listview inside a sliding drawer with a listview already present

  - by Parker

  I have an app whose main class extends ListActivity: public class GUIPrototype extends ListActivity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); final Cursor c = managedQuery(People.CONTENT_URI, null, null, null, null); String[] from = new String[] {People.NAME}; int[] to = new int[] { R.id.row_entry }; SimpleCursorAdapter adapter = new SimpleCursorAdapter(this,R.layout.drawer,c,from,to); setListAdapter(adapter); getListView().setTextFilterEnabled(true); } } I have a sliding drawer included in my XML, and I'm trying to get a separate listview to appear in the sliding drawer. I'm trying to populate the second listview using an inflater: View inflatedView = View.inflate(this, R.layout.main, null); ListView namesLV = (ListView) inflatedView.findViewById(R.id.content); String[] names2 = new String[] { "CS 345", "New Tag", "Untagged" }; ArrayAdapter<String> bb = new ArrayAdapter<String>(this, R.layout.main, R.id.row_entry, names2); namesLV.setAdapter(bb); This compiles, and runs, but the slidingdrawer is completely blank. My XML follows: <SlidingDrawer android:id="@+id/drawer" android:handle="@+id/handle" android:content="@+id/content" android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="vertical" android:layout_gravity="bottom"> <ImageView android:id="@id/handle" android:layout_width="48px" android:layout_height="48px" android:background="@drawable/icon"/> <ListView android:layout_width="fill_parent" android:layout_height="wrap_content" android:id="@id/content"/> </SlidingDrawer> I feel like I'm missing a vital step. I haven't found any resources on my problem by Googling, so any help would be greatly appreciated.

• How create a Firefox-like search textbox in WPF?

  - by Simon

  Hey there. I'm writing an application in WPF using the MVVM-pattern and will really often use TextBoxes. I don't want to use labels for the user to know user what the text box is for, i.e. I don't want something like this: <TextBlock> Name: </TextBlock> <TextBox /> Instead, I would like the TextBox to contain its own label. Statically, you would express it like this: <TextBox>Name</TextBox> If the cursor is displayed in the textbox, i.e. the TextBox gains focus, I want the description text to disappear. If the TextBox is left empty and it loses the focus, the description text should be shown again. It's similar to the search textbox of StackOverflow or the one of Firefox. (please tell me if your not sure what I mean). One TextBox's label may change at runtime, dependending on e.g. a ComboBox's selected element or a value in my ViewModel. (It's like in Firefox's search TextBox, if you select google from the search engins' menu, the TextBox's label changes to "Google", if you select "Yahoo" its set to "Yahoo"). Thus I want to be able to bind the label's content. Consider that I may already have a Binding on the Text-Property of the TextBox. How can implement such a behaviour and make it reusable for any of my TextBox's? Code is welcome but not needed; a description of what to do is enough. Thank you in advance.

• Drag String data from My Cocoa App to Third-Party Cocoa App

  - by Woodster

  Hello, I want to drag a row from my tableview and drop it into any other NSTextField in Mac OS X 10.6, and have a string of text be dropped. Drag and drop already works within my app (between a NSTableView and an NSBrowser), but I have had no success putting any data on the pasteboard that can accepted by apps other than the source application. Here's the code I tried, which I thought would be enough to get hte word "hello" to be 'pasted' when I drop into some other NSTextField: -(BOOL) tableView:(NSTableView *)tableView writeRowsWithIndexes:(NSIndexSet *)rowIndexes toPasteboard:(NSPasteboard *)pboard { [pboard declareTypes:[NSArray arrayWithObject:NSStringPboardType] owner:self]; [pboard setString:@"hello" forType:NSStringPboardType]; return YES; } //-- I never get the cursor that shows me the drop will be accepted, and it just doesn't work. Things I've tried: Using the 10.5 version of the Pasteboard identifier, NSStringPBoardType Using the 10.6 version, NSPasteboardTypeString. Setting the owner = nil, since I'm not providing the data lazily. Using the keyed archiver: [pboard setData:[NSKeyedArchiver archivedRootObject:@"Hello!!"]] None of the above have worked. I think I have the concepts correct: "Encode data, tell the pasteboard what you've got, then give it the data", but since other apps don't recognize it, I suspect I'm not telling the pasteboard the correct datatype. Where am I going wrong? Thanks, Woody

• Matplotlib pick event order for overlapping artists

  - by Ajean

  I'm hitting a very strange issue with matplotlib pick events. I have two artists that are both pickable and are non-overlapping to begin with ("holes" and "pegs"). When I pick one of them, during the event handling I move the other one to where I just clicked (moving a "peg" into the "hole"). Then, without doing anything else, a pick event from the moved artist (the peg) is generated even though it wasn't there when the first event was generated. My only explanation for it is that somehow the event manager is still moving through artist layers when the event is processed, and therefore hits the second artist after it is moved under the cursor. So then my question is - how do pick events (or any events for that matter) iterate through overlapping artists on the canvas, and is there a way to control it? I think I would get my desired behavior if it moved from the top down always (rather than bottom up or randomly). I haven't been able to find sufficient enough documentation, and a lengthy search on SO has not revealed this exact issue. Below is a working example that illustrates the problem, with PathCollections from scatter as pegs and holes: import matplotlib.pyplot as plt import sys class peg_tester(): def __init__(self): self.fig = plt.figure(figsize=(3,1)) self.ax = self.fig.add_axes([0,0,1,1]) self.ax.set_xlim([-0.5,2.5]) self.ax.set_ylim([-0.25,0.25]) self.ax.text(-0.4, 0.15, 'One click on the hole, and I get 2 events not 1', fontsize=8) self.holes = self.ax.scatter([1], [0], color='black', picker=0) self.pegs = self.ax.scatter([0], [0], s=100, facecolor='#dd8800', edgecolor='black', picker=0) self.fig.canvas.mpl_connect('pick_event', self.handler) plt.show() def handler(self, event): if event.artist is self.holes: # If I get a hole event, then move a peg (to that hole) ... # but then I get a peg event also with no extra clicks! offs = self.pegs.get_offsets() offs[0,:] = [1,0] # Moves left peg to the middle self.pegs.set_offsets(offs) self.fig.canvas.draw() print 'picked a hole, moving left peg to center' elif event.artist is self.pegs: print 'picked a peg' sys.stdout.flush() # Necessary when in ipython qtconsole if __name__ == "__main__": pt = peg_tester() I have tried setting the zorder to make the pegs always above the holes, but that doesn't change how the pick events are generated, and particularly this funny phantom event.

It shows how to draw a freehand line with the cursor by just updating one pixel when the mouse is pressed and is moving over a WPF -Image Control. writeableBitmap.Lock(); (...set the writeableBitmap.BackBuffers pixel value...) writeableBitmap.AddDirtyRect(new Int32Rect(column, row, 1, 1)); writeableBitmap.Unlock(); Now I'm trying to understand the following behaviour when moving the mouse pointer very fast: If the image/bitmap size is relatively small e.g. 800:600 pixel, then the last drawn pixel is always "synchronized" with the mouse pointers position, i.e. there is no delay, very fast reaction on mouse movements. But if the bitmap gets larger e.g. 1300:1050 pixel, you can notice a delay, the last drawn pixel always appear a bit delayed behind the moving mouse pointer. So as in both cases only one pixel gets updated with "AddDirtyRect", the reaction speed should be independent from the bitmap size!? But it seems that Writeablebitmap gets slower when it's size gets larger. Or does the whole bitmap somehow get transferred to the graphic device on every writeableBitmap.Unlock(); call , and not only the rectangle area speficied in the AddDirtyRect method? fritz

• Has anyone installed NServiceBus onto a Microsoft clustered server?

  - by David

  I am trying to install NServiceBus onto a clustered win2k3 host. The configuration utility provided (runner.exe) throw some errors that I did not catch, and it now runs correctly. When running NServiceBus.Host.exe i am get this error repeatedly: System.Transactions.TransactionAbortedException: The transaction has aborted. --- System.Transactions.TransactionManagerCommunicationException: Communication with the underlying transaction manager has failed. --- System.Runtime.InteropServices.COMException (0x8004D01B): The Transaction Manager is not available.

• [WPF] How to register to/listen to richtextbox command's?

  - by Liewe

  I'm creating a simple editor within our application using the WPF RichTextBox. Above it I've added the reguslar buttons like Bold, Italic, etc. These buttons use the RichTextBox's commands to set these properties, but next to these buttons, the commands also get send with CTRL+B, CTRL+I, etc. I want these buttons to represent the current state of the RichTextBox at the cursor. I already found out how to get this state and it works when I update this state on the SelectionChanged event. This event ofcourse isn't fired when Bold is toggled so there is no direct feedback. I would like to know if there is a way to listen to the commands being called, without affecting its original behaviour or some other ideas to solve my problems. I tried listening to the command the following way: CommandBinding boldBinding = new CommandBinding(EditingCommands.ToggleBold, CommandExecuted); _richTextBox.CommandBindings.Add(boldBinding); and private void CommandExecuted(object sender, ExecutedRoutedEventArgs e) { UpdateProperties(); e.Handled = false; } This did update the properties, but the RichTextBox didn't seem to receive the command anymore. I also tried to make my own commands on the control containing the RichTextBox, but when CTRL+B is pressed when the RichTextBox has focus, the original RichTextBox commands are called instead of the new one. Many thanks in advance! Liewe
