  • Events raised by BackgroundWorker not executed on expected thread

    - by Topdown
    A winforms dialog is using BackgroundWorker to perform some asynchronous operations with significant success. On occasion, the async process being run by the background worker will need to raise events to the winforms app for user response (a message that asks the user if they wish to cancel), the response of which captured in an CancelEventArgs type of the event. Being an implementation of threading, I would have expected the RaiseEvent of the worker to fire, and then the worker would continue, hence requiring me to pause the worker until the response is received. Instead however, the worker is held to wait for the code executed by the raise event to complete. It seems like method I am calling via the event call is actually on the worker thread used by the background worker, and I am surprised, since I expected to see it on the Main Thread which is where the mainform is running. Also surprisingly, there are no cross thread exceptions thrown. Can somebody please explain why this is not as I expect?

  • Uninstalling demo/trial of Visual Studio 2008 Team System

    - by Ian Ringrose
    I wish to uninstall the trail copy of VS 2008 Team System, as the trial is coming to its end. I had VS 2008 Professional Edition installed on the machine to start with and it still shows up in Add/Remove Problems. I am hoping that when I uninstall VS 2008 Team System I will be left with a working VS 2008 Professional Edition. When I try to uninstall VS 2008 Team System, I very quickly get an error dialog that says: A problem has been encountered while loading the setup components. Canceling setup. Help! Progress or lack there of so fare I have done dir %temp%*.log in a command prompt and can see any log files that are recent I am going to read http://en.wikipedia.org/wiki/Windows_Installer#Diagnostic_logging to see if I can get any logging Aaron Stebner's WebLog has a post on where VS put's is log files, he also has a post on were some other products put there log files gives some info about where VS setup puts it's logs etc Aaron Ruckman provided me with the solution after I sent him the log files.

  • What's happening between onResume and the activity is really displayed?

    - by Johnny
    I didn't nothing in the onResume of my Activity, but it still takes about 5 seconds between the onResume is called and the activity is really displayed. What's happening under there? Here is the code snip: onResume: @Override protected void onResume() { Log.d(TAG, "on resume >>>"); super.onResume(); } logcat: 05-28 10:36:05.621 D/LoginDialogActivity( 447): on resume >>> 05-28 10:36:06.231 I/ARMAssembler( 52): generated scanline__00000077:03010104_00000004_00000000 [ 22 ipp] (41 ins) at [0x3e3358:0x3e33fc] in 5646001 ns 05-28 10:36:10.690 I/ActivityManager( 52): Displayed activity com.aimi.appstore/.ui.activity.LoginDialogActivity: 5169 ms (total 5331 ms) AndroidManifest.xml: <activity android:name=".ui.activity.LoginDialogActivity" android:theme="@android:style/Theme.Dialog" />

  • How do I detect a change of tab page in TabControl prior to SelectedIndexChanged event?

    - by JYelton
    I currently determine what page of a tabcontrol was clicked on via the SelectedIndexChanged event. I would like to detect before the selected index actually changes, for validation purposes. For example, a user clicks a tab page other than the one they are viewing. A dialog is presented if form data is unsaved and asks if it's ok to proceed. If the user clicks no, I'd like to remain on the current tab. Currently I have to remember the previous tab page and switch back to it after an answer of 'no.' I considered MouseDown (and the assorted calculation logic), but I doubt that's the best way. (This is in .NET C# 3.5)

  • Property in a Windows Forms form class only accessable after Load event

    - by Spooky2010
    I'm instantiating and calling Form B from Form A. FormB has some custom properties, to allow me to pass it things like sqlAdaptors and dataset instances. When i instantiate and show Form B from Form A as a dialog form with a Using statement, it all works fine, but i find the properties i pass are not available in Form B until after the form_load event has fired. I was under the impression the properties when passed to a instantiated class should be available from a constructor, but this is not the case. If it try to access the properties before the form load event i get a null reference exception. Is this correct behavior ?

  • Program ends abruptly even in debugger - how did that happen?

    - by Mick
    I am trying to debug a program that unexpectedly shuts down. When I say "shuts down, I mean one moment I am seeing all the windows being displayed, each of which is showing all the right data,then suddenly all the windows disappear. The is no messagebox reporting anything wrong. So I tried running the program in the debugger hoping that it would somehow trap whatever was causing the program to abort, but even within the debugger the program simply ends abruptly. The last line in the debugger is: The program '[5500] test.exe: Native' has exited with code 0 (0x0). My program which is extremely large and extremely old has a lot of self diagnostics. My suspicion is that perhaps a self test has failed and maybe I just called "exit()", forgetting to pop up a dialog explaining why. My question now is, how can I find out from which point in the code, my program quit?

  • Twitter Authentication through Android's AccountManager classes.

    - by Robby Pond
    I am working on a twitter based app and am trying to incorporate Android's built-in Account support for Twitter. The following code works to popup the confirmation dialog for my app to access twitter but I am unsure of what to pass in as the authenticationType. Any help would be appreciated. I've googled all over the place and can't seem to find the correct answer. It goes in place of "oauth" below. AccountManager am = AccountManager.get(this); Account[] accts = am.getAccountsByType(TWITTER_ACCOUNT_TYPE); if(accts.length > 0) { Account acct = accts[0]; am.getAuthToken(acct, "oauth"/*what goes here*/, null, this, new AccountManagerCallback<Bundle>() { @Override public void run(AccountManagerFuture<Bundle> arg0) { try { Bundle b = arg0.getResult(); Log.e("TrendDroid", "THIS AUTHTOKEN: " + b.getString(AccountManager.KEY_AUTHTOKEN)); } catch (Exception e) { Log.e("TrendDroid", "EXCEPTION@AUTHTOKEN"); } }}, null); }

  • OGRE: Non-Standard Resolution

    - by Rafid K. Abdullah
    I am using OGRE to make a re-rendering of the film, which has a wide aspect ratio (around 1.85). The OGRE dialog seems to be showing the standard full screen resolution by default (800/600, 1024/768, etc.), but those obviously have aspect ratios of 1.333 or around that. But as long as I am not running full screen mode, why should I be restricted to these screen sizes only? I can definitely change the viewport size, but that would make it difficult for me to generate the video later. Any idea?

  • MVVM View reference to ViewModel

    - by BrettRobi
    I'm using MVVM in a WPF app. I'm very new to both. Let me state that I am not a purest in the MVVM pattern, I am trying to use as many best practices as I can but am trying to make what I think are reasonable compromises to make it work in our environment. For example, I am not trying to achieve 0% code in my View codebehind. I have a couple of questions about best practices. 1) I understand I don't want my VM to know about the attached View, but is it reasonable for the View to have a reference to its VM? 2) If a control in a View opens another View (such as a dialog) should I handle this in the View? It seems wrong to handle it in the VM since then the VM has some knowledge of a specific View.

  • Top tips for designing GUIs?

    - by oxbow_lakes
    A while back I read (before I lost it) a great book called GUI Bloopers which was full of examples of bad GUI design but also full of useful tidbits like Don't call something a Dialog one minute and a Popup the next. What top tips would you give for designing/documenting a GUI? It would be particularly useful to hear about widgets you designed to cram readable information into as little screen real-estate as possible. I'm going to roll this off with one of my own: avoid trees (e.g. Swing's JTree) unless you really can't avoid it, or have a unbounded hierarchy of stuff. I have found that users don't find them intuitive and they are hard to navigate and filter. PS. I think this question differs from this one as I'm asking for generalist tips

  • Management Studio default file save location

    - by jayrdub
    Open a new query window. Write some SQL. Save the script, the Save File As dialog box opens - but always to the same default location in the Profiles directory. Is there any way to set my default file location? ...Like I used to do with apps from the 1980s? Under Tools|Options a default location can be specified for query results. I need the same thing for new queries (the text editor). Tried changing locations in the Registry but SSMS just overwrote my changes. Any suggestions? (I saw this unanswered question at http://www.eggheadcafe.com/software/aspnet/30098335/management-studio-default.aspx and I had same exact question so I just reposted it here)

  • InvalidOperationException when using soap client

    - by codymanix
    I've added as wsdl file using the add servece reference dialog in vs2008. MyService serviceproxy = new MyService(); When I instantiate the service proxy, I get an InvalidOperationException with the following text (translated from german): Could not find default endpoint element to the contract "ServiceName.ServiceInterface" in the service model refers client configuration section. This may be because: The application configuration file was not found or not an endpoint in the client element item is found, which corresponded to this contract. Where servicename is the name I give the service when I add it in vs2008 and ServiceInterface the interface which is automatically generated for it.

  • Transparent child control

    - by pps
    Hello all, I'm writing a control that may have some of its parts transparent or semitransparent. Basically this control shows a png image (with alpha channel). The control's parent window has some graphics on it. Therefore, to make the png control render correctly it needs to get image of what the parent window would draw beneath it. Parent dialog might have WS_CLIPCHILDREN flag set, that means that the the parent window won't draw anything under the the png control and in this case png control won't work properly. This control has to work on Windows Mobile also, so it can't have WS_EX_TRANSPARENT

  • Show Alertdialog and use vibrator

    - by user1007522
    I'm having a class that implements RecognitionListener like this: public class listener implements RecognitionListener I wanted to show a alertdialog and use the vibrator but this isn't possible because I need to provide a context what I don't have. My alertdialog code was like this: new AlertDialog.Builder(this) .setTitle("dd") .setMessage("aa") .setNeutralButton("Ok", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { } }) .show(); But the AlertDialog.Builder(this) wants a context, the same problem with my vibrator code: v = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE); The getSystemService method isn't available. My code that starts the class: sr = SpeechRecognizer.createSpeechRecognizer(this); sr.setRecognitionListener(new listener()); Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH); intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,RecognizerIntent.LANGUAGE_MODEL_FREE_FORM); intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,"voice.recognition.test"); intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS,5); sr.startListening(intent); Whats the best way to solve this?

  • TinyMCE is glitchy/unusable in IE8

    - by Force Flow
    I'm using the jQuery version of TinyMCE 3.3.9.3 In firefox, it works fine (10 sec video depicting it in use): http://www.youtube.com/watch?v=TrAE0igfT3I In IE8 (in IE8 standards mode), I can't type or click any buttons. However, if I use ctrl+v to paste, then I can start typing, but the buttons still don't work (a 45 sec video depicting it in use): http://www.youtube.com/watch?v=iBSRlE8D8F4 The jQuery TinyMCE demo on TinyMCE's site works for me in IE8. Here's the init code: $().ready(function(){ function tinymce_focus(){ $('.defaultSkin table.mceLayout').css({'border-color' : '#6478D7'}); $('.defaultSkin table.mceLayout tr.mceFirst td').css({'border-top-color' : '#6478D7'}); $('.defaultSkin table.mceLayout tr.mceLast td').css({'border-bottom-color' : '#6478D7'}); } function tinymce_blur(){ $('.defaultSkin table.mceLayout').css({'border-color' : '#93a6e1'}); $('.defaultSkin table.mceLayout tr.mceFirst td').css({'border-top-color' : '#93a6e1'}); $('.defaultSkin table.mceLayout tr.mceLast td').css({'border-bottom-color' : '#93a6e1'}); } $('textarea.tinymce').tinymce({ script_url : 'JS/tinymce/tiny_mce.js', theme : "advanced", mode : "exact", invalid_elements : "b,i,iframe,font,input,textarea,select,button,form,fieldset,legend,script,noscript,object,embed,table,img,a,h1,h2,h3,h4,h5,h6", //theme options theme_advanced_buttons1 : "cut,copy,paste,pastetext,pasteword,selectall,|,undo,redo,|,cleanup,removeformat,|", theme_advanced_buttons2 : "bold,italic,underline,|,bullist,numlist,|,forecolor,backcolor,|", theme_advanced_buttons3 : "", theme_advanced_buttons4 : "", theme_advanced_toolbar_location : "top", theme_advanced_toolbar_align : "left", theme_advanced_statusbar_location : "none", theme_advanced_resizing : false, //plugins plugins : "inlinepopups,paste", dialog_type : "modal", paste_auto_cleanup_on_paste : true, setup: function(ed){ ed.onInit.add(function(ed){ //check for addEventListener -- primarily supported by firefox only var edDoc = ed.getDoc(); if ("addEventListener" in edDoc){ edDoc.addEventListener("focus", function(){ tinymce_focus(); }, false); edDoc.addEventListener("blur", function(){ tinymce_blur(); }, false); } }); } }); }); Any ideas as to why it's not working in IE8? [edit]: stripping everything out of the init (leaving just script_url and theme) results in the same symptoms

  • Can't send key to window with SendMessage

    - by user297313
    I'm writing a C program under Windows that should send an ENTER key to a dialog box to close it automatically. I retrieve the handle to the top level window I'm interested in (by means of EnumDesktopWindows()) and then try to send an ENTER key using SendMessage (note also that closing the window by sending WM_CLOSE works fine). None of the following works: SendMessage( hTargetWindow, WM_CHAR, VK_RETURN, 0 ); SendMessage( hTargetWindow, WM_CHAR, VK_RETURN, 1 ); SendMessage( hTargetWindow, WM_KEYDOWN, VK_RETURN, 1 ); SendMessage( hTargetWindow, WM_KEYUP, VK_RETURN, 1 ); SendMessage( hTargetWindow, WM_KEYDOWN, VK_RETURN, 1 ); SendMessage( hTargetWindow, WM_CHAR, VK_RETURN, 1 ); SendMessage( hTargetWindow, WM_KEYUP, VK_RETURN, 1 ); and so on... As a possibly simpler scenario, I also tried to send an ascii key to, say, notepad. How is this supposed to work? Thanks in advance

  • How Does Differential Execution Work?

    - by Brian
    I've seen a few mentions of this on SO, but staring at Wikipedia and at an MFC dynamic dialog demo did nothing to enlighten me. Can someone please explain this? Learning a fundamentally different concept sounds nice. Edit: I think I'm getting a better feel for it. I guess I just didn't look at the source code carefully enough the first time. I have mixed feelings about DE at this point. On the one hand, it can make certain tasks considerably easier. On the other hand, getting it up and running (i.e. setting it up in your language of choice) is not easy (I'm sure it would be if I understood it better)...though I guess the toolbox for it need only be made once, then expanded as necessary. I think in order to really understand it, I'll probably need to try implimenting it in another language.

  • What do angle brackets around an eclipse perspective mean?

    - by Karin
    I wrote a new perspective for our Eclipse RCP Project. The perspective worked fine, but because of a malconfiguration I had to revert to an earlier code-version in which this perspective didn't exist yet. The strange thing is it still gets shown in the "open perspective" Dialog. The only difference is, that it is now in angle brackets and appears two times. What do the angle brackets mean? (unresolved title perhaps?) And how can I get rid of these entries? Thanks a lot!

String values are being posted perfectly however when it comes to boolean values, they are not being passed at all. Below is my code: var gsGasolineField = $('.gsGasoline').val(); blData = { Gasoline: gsGasolineField }; var json = JSON.stringify(blData); $.ajax({ type: "POST", url: url, data: json, contentType: "application/json", dataType: "json", statusCode: { 201 /*Created"*/: function (data) { $("#BusinessLayerDialog").dialog("close"); ClearForm("#BusinessLayerForm"); }, 400: /*Bad request - validation error*/ function (data) { $("#BusinessLayerForm").validate().form(); }, 500: function (data) { alert('err'); } }, beforeSend: setHeader }); Gasoline property is of type boolean on the server side.

  • JDBC ResultSet.getString Before/After Start/End of ResultSet Exception

    - by Geowil
    I have done a lot of searching about this topic through Google but I have yet to find someone using getString() in the way that I am using it so I have not been able to fix this issue in the normal ways that are suggested. What I am trying to do is to obtain all of the information from the database and then use it to populate a table model within the program. I do so by obtaining the data with getString and place it into a String[] object: try { while (rSet.next()) { String row[] = {rSet.getString("DonorName"),rSet.getString("DonorCharity"),((String)rSet.getString("DonationAmount"))}; model.addRow(row); } } However I am always getting a dialog error message stating those error messages in the title: Exception: Before start of result set Exception: After end of result set The data is still added and everything works correctly but it is just annoying to have to dismiss those message windows. Does anyone have some suggestions?

  • Choosing connectionstring in VB.NET application at startup

    - by MatsT
    I have a VB.NET application with a connection to an SQL Server 2003. On the server there are two databases, MyDatabase and MyDatabase_Test. What I would like to do is to show a dialog when the program starts that let's the user choose which database to use. My idea is to create a new form as the starup form that sets this property and then launches the main form. Currently the connectionstring is specified in the application config file. Best would be if I can specify two different connection strings in that file to choose from, but for now it is also acceptable with other solutions like hardcoding the two connectionstrings into the startup form.
