• InfoPath FormControl on STA worker thread

  - by Rob Ford

  I have a .NET class that exposes two public methods: one to create an InfoPath form and another to Export to one of the supported formats. I’m using the Microsoft FormControl to do this. It’s hosted by a Form that does not get displayed. I get called by a Winforms app, but on an MTA worker thread instead of the UI thread. So I create an STA thread and execute on that, which works exactly once and then results in this exception: System.InvalidOperationException was unhandled Message="Unable to get the window handle for the 'FormControl' control. Windowless ActiveX controls are not supported." Source="System.Windows.Forms" StackTrace: at System.Windows.Forms.AxHost.EnsureWindowPresent() at System.Windows.Forms.AxHost.InPlaceActivate() at System.Windows.Forms.AxHost.TransitionUpTo(Int32 state) at System.Windows.Forms.AxHost.CreateHandle() at System.Windows.Forms.Control.CreateControl(Boolean fIgnoreVisible) at System.Windows.Forms.Control.CreateControl(Boolean fIgnoreVisible) at System.Windows.Forms.AxHost.EndInit() at InfoPathCreateStaThreadTest.FormControlHost.InitializeComponent() in C:\Windows\Temp\InfoPathCreateStaThreadTest\InfoPathCreateStaThreadTest\FormControlHost.Designer.cs:line 65 After some experimenting, I started to suspect this is a message pumping problem. I then came across this, which makes me more strongly suspect so: http://blogs.msdn.com/cbrumme/archive/2004/02/02/66219.aspx I tried various methods of pumping messages with no luck. I should mention that the alternative of automating the InfoPath app is not viable unless I can figure out how to hide the app. Any help would be much appreciated.

• Make PasswordRecovery control work with locked out users ?

  - by Moe Sisko

  Example scenario in an ASP.NET application using SQL Server membership provider : 1) a user can't remember their exact password, and tries many times in a short space of time to login with an invalid password (say 5 times in a 10 minute window). This locks out the user (i.e. sets the IsLockedOut flag of the aspnet_Membership table to 1). 2) user goes to the "forgot my password" screen to try to get a new password emailed to them. This screen uses the PasswordRecovery control. User enters their correct user id, but then cannot go further in the password recovery process, since the IsLockedOut flag is 1. (They don't even get to see their security question). 3) The user would then have to phone tech support to get themselves unlocked etc. To reduce the burden on support staff, we are trying to eliminate step 3) if possible, by making the PasswordRecovery control (if possible), work with locked out users. i.e. when they enter their login ID, the security question comes up, and IF they enter the correct answer, the system will unlock the user, then send the new email to them. I'm wondering if it is possible to tweak the PasswordRecovery control to do this. Or maybe I'm approaching this the wrong way ?

• How do you program a windows service in C# to start an application for a user?

  - by Swoop

  Is it possible to start a program so that it is available to a user with a windows service? I have been working with the Process.Start() in C#. I can get the service to kickoff some sort of process that appears in the Task Manager list under processes. However, the program nevers appears on the screen. By default, it runs under the user name "SYSTEM". I have adjusted the "Log On" option in the service manager to match the person logged into the computer, but this does not cause a window to appear either. I feel like I am either missing a simple setting, or need to take a different direction for this. Below is the code I have been working with to start up Firefox as a test app. private void startRunDap() { ProcessStartInfo startInfo = new ProcessStartInfo(); startInfo.FileName = "Firefox"; startInfo.WindowStyle = ProcessWindowStyle.Normal; startInfo.UseShellExecute = true; Process.Start(startInfo); //Process.Start("Firefox"); }

• How do I correctly decode unicode parameters passed to a servlet

  - by Grant Wagner

  Suppose I have: <a href="http://www.yahoo.com/" target="_yahoo" title="Yahoo!&#8482;" onclick="return gateway(this);">Yahoo!</a> <script type="text/javascript"> function gateway(lnk) { window.open(SERVLET + '?external_link=' + encodeURIComponent(lnk.href) + '&external_target=' + encodeURIComponent(lnk.target) + '&external_title=' + encodeURIComponent(lnk.title)); return false; } </script> I have confirmed external_title gets encoded as Yahoo!%E2%84%A2 and passed to SERVLET. If in SERVLET I do: Writer writer = response.getWriter(); writer.write(request.getParameter("external_title")); I get Yahoo!â„¢ in the browser. If I manually switch the browser character encoding to UTF-8, it changes to Yahoo!TM (which is what I want). So I figured the encoding I was sending to the browser was wrong (it was Content-type: text/html; charset=ISO-8859-1). I changed SERVLET to: response.setContentType("text/html; charset=utf-8"); Writer writer = response.getWriter(); writer.write(request.getParameter("external_title")); Now the browser character encoding is UTF-8, but it outputs Yahoo!â?¢ and I can't get the browser to render the correct character at all. My question is: is there some combination of Content-type and/or new String(request.getParameter("external_title").getBytes(), "UTF-8"); and/or something else that will result in Yahoo!TM appearing in the SERVLET output?

• How do I pass parameters between request-scoped beans

  - by smayers81

  This is a question that has been bothering me for sometime. My application uses ICEFaces for our UI framework and Spring 2.5 for Dependency Injection. In addition, Spring actually maintains all of our backing beans, not the ICEFaces framework, so our faces-config is basically empty. Navigation is not even really handled through navigation-rules. We perform manual redirects to new windows using window.open. All of our beans are defined in our appContext file as being request-scoped. I have Page ABC which is backed by BackingBeanABC. Inside that backing bean, I have a parameter say: private Order order; I then have Page XYZ backed by BackingBeanXYZ. When I redirect from page ABC to page XYZ, I want to transfer the 'order' property from ABC to XYZ. The problem is since everything is request-scoped and I'm performing a redirect, I am losing the value of 'description'. There has got to be an easier way to pass objects between beans in request scope during a redirect. Can anyone assist with this issue?

• SDL with OpenGL (freeglut) crashes on call to glutBitmapCharacter

  - by stett

  I have a program using OpenGL through freeglut under SDL. The SDL/OpenGL initialization is as follows: // Initialize SDL SDL_Init(SDL_INIT_VIDEO); // Create the SDL window SDL_SetVideoMode(SCREEN_W, SCREEN_H, SCREEN_DEPTH, SDL_OPENGL); // Initialize OpenGL glClearColor(BG_COLOR_R, BG_COLOR_G, BG_COLOR_B, 1.f); glViewport(0, 0, SCREEN_W, SCREEN_H); glMatrixMode(GL_PROJECTION); glLoadIdentity(); glOrtho(0.0f, SCREEN_W, SCREEN_H, 0.0f, -1.0f, 1.0f); glEnable(GL_TEXTURE_2D); glEnable(GL_BLEND); glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); I've been using glBegin() ... glEnd() blocks without any trouble to draw primitives. However, in this program when I call any glutBitmapX function, the program simply exits without an error status. The code I'm using to draw text is: glColor3f(1.f, 1.f, 1.f); glRasterPos2f(x, y); glutStrokeString(GLUT_BITMAP_8_BY_13, (const unsigned char*)"test string"); In previous similar programs I've used glutBitmapCharacter and glutStrokeString to draw text and it's seemed to work. The only difference being that I'm using freeglut with SDL now instead of just GLUT as I did in previous programs. Is there some fundamental problem with my setup that I'm not seeing, or is there a better way of drawing text?

• How to load JPG file into NSBitmapImageRep?

  - by Adam

  Objective-C / Cocoa: I need to load the image from a JPG file into a two dimensional array so that I can access each pixel. I am trying (unsuccessfully) to load the image into a NSBitmapImageRep. I have tried several variations on the following two lines of code: NSString *filePath = [NSString stringWithFormat: @"%@%@",@"/Users/adam/Documents/phoneimages/", [outLabel stringValue]]; //this coming from a window control NSImageRep *controlBitmap = [[NSImageRep alloc] imageRepWithContentsOfFile:filePath]; With the code shown, I get a runtime error: -[NSImageRep imageRepWithContentsOfFile:]: unrecognized selector sent to instance 0x100147070. I have tried replacing the second line of code with: NSImage *controlImage = [[NSImage alloc] initWithContentsOfFile:filePath]; NSBitmapImageRep *controlBitmap = [[NSBitmapImageRep alloc] initWithData:controlImage]; But this yields a compiler error 'incompatible type' saying that initWithData wants a NSData variable not an NSImage. I have also tried various other ways to get this done, but all are unsuccessful either due to compiler or runtime error. Can someone help me with this? I will eventually need to load some PNG files in the same way (so it would be nice to have a consistent technique for both). And if you know of an easier / simpler way to accomplish what I am trying to do (i.e., get the images into a two-dimensional array), rather than using NSBitmapImageRep, then please let me know! And by the way, I know the path is valid (confirmed with fileExistsAtPath) -- and the filename in outLabel is a file with .jpg extension. Thanks for any help!

• Looking for good PHP editor or IDE with 'IntelliSense'

  - by Andrew

  Hello, I'm looking for suitable PHP Editor or IDE with syntax auto-completion. I've tried trial versions of programs like Zend Studio, PHPDesigner, NetBeans PHP, NuSphere PhpED, and similar -- but none of them fully satisfied me. I quite liked hint window with detailed info about what function does and what it returns. Also I liked the way NetBeans auto-complete code (for example inserts all required parameters in function declaration as "dummy fields" and then you can jump between them using TAB in order to edit them). On the other hand, environment of NetBeans doesn't belong to the nicest. In this regard I prefer PHPDesigner with its sleek and light interface. At this moment I don't use any of the debugging options, since I don't know yet how to use profiller, breakpoints, watches and what not, so at this point my only concern is good autocompletion. For this purpose NetBean would be great choice, but with future in mind I am not sure debugging will be good in NetBeans, especially as I would prefer to use remote Linux server for this. So in short, I'm looking for editor that: Have similar code auto-completion (IntelliSense) like NetBeans Allow you to debug code using remote server (or sets up own debugging server like PHPDesigner does) without need to run Apache and similar on local computer Is preferably easy to use / intuitive interface Any ideas?

• getting an error on jslint while creating a new object using javascript

  - by user3712689

  For some reason this code is giving a lint. I can't really figure out why. It says: 'was expecting a assignment or function call, and instead saw an expression.' What does that mean? window.onload = function (){ function SuspectOne (naam, leeftijd, wie){ this.naam = Spencer Hawes; this.leeftijd = 22; this.wie = zoon van de man; } function SuspectTwo (naam, leeftijd, wie){ this.naam = Tyrone Biggums; this.leeftijd = 28; this.wie = lokale herionejunk; } function SuspectThree (naam, leeftijd, wie){ this.naam = Ellie Campbell Hawes; this.leeftijd = 40; this.wie = vrouw van de man; } var verdachten = new Array[]; verdachten[0] = new Verdachte("Spencer Hawes", 22, "zoon van de man"); verdachten[1] = new Verdachte("Tyrone Biggums", 28, "lokale herionejunk"); verdachten[2] = new Verdachte("Ellie Spencer Hawes", 40, "vrouw van de man"); for(x=0; x<verdachten.length; x++){ console.log("De verdachte is de " + verdachten[x].leeftijd + "jaar oud " + verdachten[x].naam + ", de " + verdachten[x].wie); } }; Can someone help me with this? I would really like a lint free code.

• How do I pass a LuaTable between two Lua states using LuaInterface?

  - by user316675

  I've been trying to pass a LuaTable class between two Lua states, like so: LuaManager L1 = new Lua(); LuaManager L2 = new Lua(); LuaTable table = L1.DoString("return {apple = 25}")[0]; L2["tbl"] = table; double results = L2.DoString("return tbl[\"apple\"]")[0]; Assert.AreEqual(25.0, results); The above test fails; I receive a return value of nil. Using the Immediate Window confirms that "table" is a non-null object, and that table["apple"] returns 25; it's something that's being lost in translation to L2. Interestingly, when the object is loaded back into the same state, the test works, like so: //Succeeds LuaManager lua = new Lua(); LuaTable table = lua.DoString("return {apple = 25}")[0]; lua["tbl"] = table; double results = lua.DoString("return tbl[\"apple\"]")[0]; Assert.AreEqual(25.0, results); How can I safely pass the LuaTables without hassles? Thanks in advance!

• server caching problem on ASP.NET MVC page

  - by Rita

  Hi I have server caching error on ASP.NET MVC Pages. The scenario is like this. I have two applications (1).External Website and (2).Internal Adminsite, both pointing to the same Database. There is one page called EditProfile Page on the External Website that registered customer can update his profile information like Firstname, Lastname and Address…etc. Similarly there is similar functionality on the Internal Adminsite on the page called CustomerProfile Page where the Site Admin can update all these fields. When the user updates the profile information from the Adminsite, those updates are not reflecting back to the Website. Now I tried restarting the Website on IIS and that din’t help. Again I tried both restarting the Website on IIS and opening a new browser, then those updates are reflecting back. I am wondering how I can come out of this caching problem without restarting the site and open a new browser window everytime? Are there any IIS settings that could help? This caching is happening only on couple of tables only and all the updates are showing up in the database. Appreciate your responses. Thanks

• How to mark array value types in PHP (Java)Doc?

  - by Christian Sciberras

  It might be a bit difficult to explain, so I'll give some example code. Note that I'm using NetBeans IDE (latest). class Dummy { public function say(){ } } /** * Builds dummy class and returns it. * @return Dummy The dummy class. */ function say_something(){ return new Dummy(); } $s=say_something(); While developing in netbeans I can invoke auto-complete by hitting ctrl+space after typing "$s-". In the the hint window that follows, there is the item "say()". This is because the javadoc says say_something returns a Dummy and NetBeans parsed Dummy class to know that it has a method called "say()". So far so good. My problem is with arrays. Example code follows: /** * Builds array of 2 dummy classes and returns it. * @return Array The dummy class. (*) */ function say_something2(){ return array(new Dummy(),new Dummy()); } $s=say_something2(); If I try the auto-complete thing again but with "$s[0]-" instead, I don't get the methods fro Dummy class. This is because in the JavaDoc I only said that it is an array, but not the values' type. So the question would be, is there any JavaDoc syntax, cheat, whatever which allows me to tell JavaDoc what type of variables to expect in an array?

• Can I specify the files to commit in subversion in a file rather than on the command line?

  - by René Nyffenegger

  I have renamed (with svn move) a lot of files in a subversion project. Now, I am trying to commit these on Window's cmd.exe. It seems that I hit a limit (probably by cmd.exe) in that the number of files is too long for the command line to swallow. Now, I thought and hoped that I could list the files to commit in a seperate file that I could specify with the commit command (something like svn ci --files-to-commit=renamed-files.txt -m "Renamed a lot of files" Yet, either such an option does not exist or I am unable to find this. Unfortunately, I cannot do a svn ci . as I have done other changes in the project as well. Neither can I do a svn ci *pattern-of-renamed-files* since this would only check in the added files, not the deleted ones. Before I start checking in the files with smaller chunks of files to check in (and thus increase the revision number uneccesserily without giving a hint as to the 'atomicity' of the operation) I thought I ask if this is indeed impossible to do.

• problem loading texture with transparency with OpenGL ES and Android

  - by Evan Kimia

  Im trying to load an image that has background transparency that will be layered over another texture. When i try and load it, all i get is a white screen. The texture is 512 by 512, and its saved in photoshop as a 24 bit PNG (standard PNG specs in the Photoshop Save for Web and Devices config window). Any idea why its not showing? The texture without transparency shows without a problem. Here is my loadTextures method: public void loadGLTexture(GL10 gl, Context context) { //Get the texture from the Android resource directory Bitmap bitmap = BitmapFactory.decodeResource(context.getResources(), R.drawable.m1); Bitmap normalScheduleLines = BitmapFactory.decodeResource(context.getResources(), R.drawable.m1n); //Generate texture pointers... gl.glGenTextures(3, textures, 0); //...and bind it to our array gl.glBindTexture(GL10.GL_TEXTURE_2D, textures[1]); //Create Nearest Filtered Texture gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MIN_FILTER, GL10.GL_LINEAR_MIPMAP_NEAREST); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MAG_FILTER, GL10.GL_LINEAR); gl.glTexParameterf(GL11.GL_TEXTURE_2D, GL11.GL_GENERATE_MIPMAP, GL11.GL_TRUE); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_S, GL10.GL_CLAMP_TO_EDGE); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_T, GL10.GL_CLAMP_TO_EDGE); GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, bitmap, 0); bitmap.recycle(); //Bind our normal schedule bus map lines gl.glBindTexture(GL10.GL_TEXTURE_2D, textures[0]); //Create Nearest Filtered Texture gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MIN_FILTER, GL10.GL_LINEAR_MIPMAP_NEAREST); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MAG_FILTER, GL10.GL_LINEAR); gl.glTexParameterf(GL11.GL_TEXTURE_2D, GL11.GL_GENERATE_MIPMAP, GL11.GL_TRUE); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_S, GL10.GL_CLAMP_TO_EDGE); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_T, GL10.GL_CLAMP_TO_EDGE); GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, GL10.GL_RGBA, normalScheduleLines, 0); normalScheduleLines.recycle(); }

• How to properly log out of facebook

  - by Gublooo

  This is a repeated question and I have followed both the suggestions provided in these StackOverflow links: How to log-out users using FaceBook connect in php and zend Trouble logging out of a FaceBook connect site and destroying sessions The issue is - the code works 90% of the time. Thats the weird part. Out of the 100 times I've logged in and out - I've experienced this problem 5-6 times and 2 of my beta test users have reported the same issue. So when it works- if u click the logout link - u get the facebook popup saying - you being logged out - when it does'nt work - absolutely nothing happens - the page does not refresh - it just sits on that page doing nothing. This is the javascript code that gets called on clicking logout function logout() { FB.Connect.get_status().waitUntilReady(function(status) { switch(status) { case FB.ConnectState.connected: FB.Connect.logoutAndRedirect("http://www.example.com/login/logout"); break; case FB.ConnectState.userNotLoggedIn: window.location = "http://www.example.com/login/logout"; break; } }); return false; } This is the php code: $this-_auth-clearIdentity(); $face = Zend_Registry::get('facebook'); $fb = new Facebook($face['appapikey'], $face['appsecret']); //$fb-clear_cookie_state(); $fb-expire_session(); Anyone experienced such sporadic issues.

• launch two actions in one button ASP.NET

• jQuery ajax returns

  - by Tom

  I think this will be some obvious problem, but I cannot figure it out. I hope someone can help me. So I have a slider with 3 slides - Intro, Question, Submit Now I want to make sure that if the question is answered wrong people cannot slide to Submit. The function to move slide is like this: function changeSlide(slide){ // In case current slide is question check the answer if (jQuery('.modalSteps li.current',base).hasClass('questionStep')){ checkAnswer(jQuery('input[name="question_id"]',base).val(), jQuery('input[name="answer"]:checked',base).val()); } jQuery('.modalSteps li.current',base).fadeOut('fast',function(){ jQuery(this).removeClass('current'); jQuery(slide).fadeIn('fast',function(){ jQuery(slide).addClass('current'); }); }); // In case the new slide is question, load the question if (jQuery(slide).hasClass('questionStep')){ var country = jQuery('input[name="country"]:checked',base).val(); loadQuestion(country); } } Now as you can see on first lines, I am calling function checkAnswer, which takes id of question and id of answer and pass it to the AJAX call. function checkAnswer(question, answer){ jQuery.ajax({ url: window.base_url+'ajax/check_answer/'+question+'/'+answer+'/', success: function(data){ if (!data.success){ jQuery('.question',base).html(data.message); } } }); } The problem i am having is that I cannot say if(checkAnswer(...)){} Because of Ajax it always returns false or undefined. What I need is something like this: function changeSlide(slide){ // In case current slide is question check the answer if (jQuery('.modalSteps li.current',base).hasClass('questionStep')){ if (!checkAnswer(jQuery('input[name="question_id"]',base).val(), jQuery('input[name="answer"]:checked',base).val())){ return false; } } ... So it will prevent the slide from moving on. Now when Im thinking about it, I will probably have slide like "Wrong answer" so I could just move the slide there, but I would like to see the first solution anyway. Thank you for tips

• Form not updating usercontrol

  - by user328259

  From the post "Growing user control not updating"... Using C#, .Net 2.0 in a Windows environment. UserControl1 - draws cells to a bitmap buffer dependent upon NumberOfCells property UserControl2 - panel contains UserControl1 which displays vertical scroll when necessary; also contains NumberOfCells which sets UserControl1's NumberOfCells. Formf1 - contains NumericUpDown controls (just increments) which updates the UserControl2 - suppose to! When I increment the control on the form by say 20, UserControl1 adds the necessary cells, UserControl2 displays the vertical scroll bar accordingly, BUT the form does not 'redraw' to the updated/correct image!! Meaning, after I increment by 20, cells are added, vertical scrool bar added... but the image shown is just everything else expanding. I reset the control to scoll to the very TOP and the scrolling works, but the image is still staic... UNTIL I resize my form, more specifically, when I change it from maximize to window or vice versa!!! What can I do to 'reset/redraw' the correct image???? Thank you in advance. Lawrence

• NOT A DUPLICATE! VS2010 - How to automatically stop compile on first compile error

  - by Ben Robbins

  {rant}First I'd like to say that this IS NOT A DUPLICATE. I've asked this question previously but it got closed as a duplicate when it isn't. This question is SPECIFIC to VS 2010 and the answers to the so-called duplicate work in VS 2008 but not in VS 2010 (at least not for me or anyone I know). So before you go closing something as a duplicate how about you read the question carefully and try the answer for yourself and see if it actually works. Apologies for the rant but there is no obvious way to contact the SO police that closed the issue or get it reopened. {/rant} At work we have a C# solution with over 80 projects. In VS 2008 we use a macro to stop the compile as soon as a project in the solution fails to build (see this question for several options for VS 2005 & VS 2008: http://stackoverflow.com/questions/134796/how-to-automatically-stop-visual-c-build-at-first-compile-error). Is it possible to do the same in VS 2010? What we have found is that in VS 2010 the macros don't work (at least I couldn't get them to work) as it appears that the environment events don't fire in VS 2010. The default behaviour is to continue as far as possible and display a list of errors in the error window. I'm happy for it to stop either as soon as an error is encountered (file-level) or as soon as a project fails to build (project-level). Answers for VS 2010 only please. If the macros do work then a detailed explanation of how to configure them for VS 2010 would be appreciated. Thanks.

• Displaying progressbar using threading in win 32 applicaition!

  In my application I have a simple module were I will read files for some process that will take few seconds..so I thought of displaying a progress bar(using worker thread) while the files are in progress.I have created a thread (code shown below) and also I designed a dialog window with progress control.I used the function MyThreadFunction below to display the progressbar but it just shows only one time and disappears,I am not sure how to make it work.I tried my best inspite of the fact that I am new to threading. reading files void ReadMyFiles() { for(int i = 0; i < fileCount ; fileCount++) { CWinThread* myThread = AfxBeginThread((AFX_THREADPROC)MyThreadFunction,NULL); tempState = *(checkState + index); if(tempCheckState == NOCHECKBOX) { //my operations } else//CHECKED or UNCHECKED { //myoperation } myThread->PostThreadMessage(WM_QUIT,NULL,NULL); } } thread functions UINT MyThreadFunction(LPARAM lparam) { HWND dialogWnd = CreateWindowEx(0,WC_DIALOG,L"Proccessing...",WS_OVERLAPPEDWINDOW|WS_VISIBLE, 600,300,280,120,NULL,NULL,NULL,NULL); HWND pBarWnd = CreateWindowEx(NULL,PROGRESS_CLASS,NULL,WS_CHILD|WS_VISIBLE|PBS_MARQUEE,40,20,200,20, dialogWnd,(HMENU)IDD_PROGRESS,NULL,NULL); MSG msg; PostMessage( pBarWnd, PBM_SETRANGE, 0, MAKELPARAM( 0, 100 ) ); PostMessage(pBarWnd,PBM_SETPOS,0,0); while(PeekMessage(&msg,NULL,NULL,NULL,PM_NOREMOVE)) { if(msg.message == WM_QUIT) { DestroyWindow(dialogWnd); return 1; } AfxGetThread()->PumpMessage(); Sleep(40); } return 1; }

• Getting the highlighted text inside selected element only.

  - by ashays

  My goal is to be able to get the highlighted text within a document, but only if that text is within a given section, and then apply a certain style to that selected text after clicking a div tag. I'll explain what I mean: So, having looked at window.getSelection() and document.selection.createRange().text, I attempted to use elmnt.getSelection() or elmnt.selection.createRange().text for some HTML element, elmnt. However, it doesn't seem to work, so that idea seems pretty null. This means I can't use this idea to determine the text that is highlighted within a given location. In case this doesn't make sense, essentially, I want html code that looks like this: <body> <div id="content">Stuff here will not be effected</div> <div id="highlightable">Stuff here can be effected when highlighted</div> <div id="morecontent">Stuff here will also not be effected</div> </body> So that whenever I've highlighted text, clicking on a specified div will apply the proper CSS. Now, on to the div tags. Basically, here's what I've got on that: $('.colorpicker').click( function(e) { console.log(getSelectedText()); } Eventually, all I want this to highlight the selected text and have the div tag change the color of the selected text to that of the respective div tag that I've selected. Neither of these seems to be working right now, and my only guess for the reason of the div tag is that it unhighlights whatever I've got selected whenever I click on the div tag. Fallbacks: If there is more than one time that 'abc' is found on the page and I highlight to color 'abc', I would like that only that copy of 'abc' be highlighted. I know this is a lot in one question, but even if I could get a little head start on this idea, my next personal project would be going a lot more smoothly. Thanks. :)

• How to manage multiple python versions ?

  - by Gyom

  short version: how can I get rid of the multiple-versions-of-python nightmare ? long version: over the years, I've used several versions of python, and what is worse, several extensions to python (e.g. pygame, pylab, wxPython...). Each time it was on a different setup, with different OSes, sometimes different architectures (like my old PowerPC mac). Nowadays I'm using a mac (OSX 10.6 on x86-64) and it's a dependency nightmare each time I want to revive script older than a few months. Python itself already comes in three different flavours in /usr/bin (2.5, 2.6, 3.1), but I had to install 2.4 from macports for pygame, something else (cannot remember what) forced me to install all three others from macports as well, so at the end of the day I'm the happy owner of seven (!) instances of python on my system. But that's not the problem, the problem is, none of them has the right (i.e. same set of) libraries installed, some of them are 32bits, some 64bits, and now I'm pretty much lost. For example right now I'm trying to run a three-year-old script (not written by me) which used to use matplotlib/numpy to draw a real-time plot within a rectangle of a wxwidgets window. But I'm failing miserably: py26-wxpython from macports won't install, stock python has wxwidgets included but also has some conflict between 32 bits and 64 bits, and it doesn't have numpy... what a mess ! Obviously, I'm doing things the wrong way. How do you usally cope with all that chaos ?e

• python VTE Terminal weirdness

  - by mykhal

  i'm trying to use the terminal from python VTE binding (python-vte from debian squeeze) as a virtual terminal emulator (just for ANSI/control chars text processing) in interactive python console, everything looks (almost) all right: >>> import vte >>> term = vte.Terminal() >>> term.feed("a\nb") >>> print repr(term.get_text(lambda *a: True).rstrip()) 'a\n b' however, launching this code (little modified) as python script, different result is yielded: $ python vte_wiredness_1.py '' strangely enough, pasting the code back into the (new) interactive python session also yields empty string: >>> import vte >>> term = vte.Terminal() >>> term.feed("a\nb") >>> print repr(term.get_text(lambda *a: True).rstrip()) '' >>> first thing caming on my mind was that the only difference between the two cases is the timing - there had to be some delay before get_text. unfortunately, preluding get_text with some seconds sleep did not help then i thought it has something to do with X window environment. but the results are the same pure linux console (with some warning on missing graphics). i wonder what causes such an unpredictable behavior (interactive console - pasted vs typed, and it's not the delay.. ant the interactive console has nothing to do with the vte terminal object.. i guess) can someone explain what is happening? is it possible to use the VTE Term such way? that the "b" letter in the output is preceded by the space, is another strangeness (all consecutive lines are preceded by more spaces.. looks like I have to send carriage return before the string.) (the lambda *a: True get_text method argument i'm using is a dummy callback, it's is some SlotSelectedCallback.. for its explanation i'd be grateful as well :) )
