• Integrating virtual keyboard on a HP TouchSmart with an Adobe AIR app

  - by Alan

  Hi, Does anyone know if it's possible to integrate the ToushSmart's virtual keyboard with an Adobe AIR application? In most programs (Internet Explorer, Firefox, etc), when a user touches a text field a little keyboard icon automatically pops up which, when pressed, will bring up the virtual keyboard. However, this doesn't happen when clicking on text input fields in Adobe AIR applications. Has anyone had any experience working with AIR/Flash and touchscreens? Is there any API that can tell Windows (or the HP virtual keyboard specifically) that the user has clicked in a text field and that the virtual keyboard should be shown? The text fields are the standard kind (fl.controls.TextInput). Any suggestions would be greatly appreciated. Thanks in advance!

• Load HTML frames in a specific order without back button problems?

  - by Joergen Bech

  I have a web page that uses a frameset. Due to scripting and object dependencies, I need to load the frames in a specific order. I have used this example as a template: The JavaScript Source: Navigation: Frames Load Order This loads an empty page in place of the page I need to load last, then replaces it with the correct page after the first page has loaded. However: I also need to use the browser Back button. If you run the sample at the above link, let both frames load, then click the Back button, the top frame reverts to the temporary blank page. It is then necessary to click the Back button again to navigate to the page before the frameset. Is there a way to force frames to load in a specific order without this Back button behavior - or a way to force the Back button to skip the empty page? This needs to work with Internet Explorer 6 and 7 and preferably with Firefox 3 as well.

• Storing source files outside project file directory in Visual Studio C++ 2009

  - by Skurmedel

  Visual Studio projects assumes all files belonging to the project are situated in the same directory as the project file, or one underneath it. For a particular project (in the non-Visual Studio sense) this is not what I want. I want to store the MSVC-specific files in another folder, because there might be other ways to build the application as well, for example with SCons. Also all the stuff MSVC splurts out clutters the source directory. Example: /source /scons /msvc <- here is where I want my MSVC-specific stuff I can add the files, in Explorer, to the source directory manually, and then link them in Visual Studio with the project. It's not the end of the world, but it annoys me a bit that Visual Studio tries to dictate the folder structure of my project. I was looking through the schemas for the project files but realized that this annoying assumption is in the IDE and not the format of the project files. Do someone know a neater way to solve this than manually linking files to the project from the source directory?

• WPF Animation of border width

  - by Dave Perry

  I've got a dockpanel on my ui as follows; <DockPanel> <Border DockPanel.Dock="Top">Header</Border> <Border DockPanel.Dock="Bottom">My footer</Border> <Border DockPanel.Dock="Left">Menu</Border> <Border>Content</Border> </DockPanel> What I want to do is to have a storyboard animation to show / hide the Menu on the left-hand side. I've got my border to increase the width when it has loaded but I want a way to close / reopen it. I need a button somewhere but I want this to trigger the animation in the border control rather than itself. Ideally I was thinking of something like the Toolbox / Server Explorer in visual studio. Does anyone have any pointers / examples for getting started? Thanks

• Why are mercurial subrepos behaving as unversioned files in eclipse

  - by noam

  I am trying to use the subrepo feature of mercurial, using the mercurial eclipse plugin . I created and added the .hgsub file in the root repo, put all the mappings of the sub repos in it, and committed + pushed. Then, I pulled the root repo in eclipse, using import-mercurial. Now I see that all the subrepos appear as though they are unversioned (no "orange cylinder" icon next to their corresponding folders in the eclipse file explorer). Furthermore, when I right click on one of the subrepos, I don't get all the hg commands in the "team" menu as I usually get, with root projects - no "pull", "push" etc. Also, when I made a change to a file in a subrepo, and then "committed" the root project, it told me there were no changes found.

• JQuery - Form Submission

  - by user70192

  Hello, I have a web page that has a DIV and an IFRAME. When a user clicks a button in my DIV, I need to submit the web form that is hosted in my IFRAME. Both pages are hosted on the same server in the same directory. My code that attempts to submit the web form looks like this: $("#myIFrame").contents().find("form").submit(); When this code is called, I receive an error in IE that says: "Internet Explorer cannot display the webpage" In FireFox when I execute the code, I receive an error that says: "The connection was reset" In FireFox when I look at the error console I see: "Error: Permission denied for http://localhost:2995 to get property HTMLDocument.nodeType from ." What am I doing wrong?

• VB.Net: How to fill in a form in a website, then click at a button and download the file using webbr

  - by BasisBit

  I am using a WebBrowser-Control to fill in a webform and then click at a button, this currently results in a standard Download File Dialog (you get these if you download a file using internet explorer), but instead, I have to catch this file and save it automatically with a by me defined name to a specific folder. I am trying to code a little application in vb.net which download the Export-file from my wordpress-blog, and I want to do this completely without user-interaction. Currently everything works, except the downloading of the file. I tried to catch it with the event System.Windows.Controls.WebBrowser.Navigating(ByVal Object, ByVal System.Windows.Navigation.NavigatingCancelEventArgs) but I don't see where to download the file from :( I hope you guys can help me.

• Prototype's Ajax.Request not working in Chrome

  - by Jason

  I am just doing a simple Ajax.Request call using the newest version of Prototype. It works fine in Firefox, Internet Explorer, and even Safari... but not in Chrome. Here is my code... alert(url); new Ajax.Request(url, { method: 'get', onSuccess: function(transport) { alert('test'); } }); It pops up he URL alert but the test alert never comes up. Like I said it does in every other browser. I am not getting any javascript errors and I have used Firebug. I did a console.log on each event and it gets to the onLoading stage of Ajax.Request but never onLoaded. Very confused... ?

• Tag a process with a string

  - by AlexDrenea

  Hi guys, I am trying to reproduce Process Exporer's feature to tag a process running on the current machine with a Comment (Please see the Comment section in the Process properties in Process Explorer). I couldn't find any way to do it with managed code, had a try with wmic utility but I wasn't able to find a way to set a property to an existing process. Also, searching the web returns some pretty vague responses since all the search terms are so general.. If anybody has at least a hint I will appreciate it. Alex. P.S I am using C# for the project but I am opened to use unmanaged code if that's what it takes :)

• Update Rule in Temporal difference

  - by Betamoo

  The update rule TD(0) Q-Learning: Q(t-1) = (1-alpha) * Q(t-1) + (alpha) * (Reward(t-1) + gamma* Max( Q(t) ) ) Then take either the current best action (to optimize) or a random action (to explorer) Where MaxNextQ is the maximum Q that can be got in the next state... But in TD(1) I think update rule will be: Q(t-2) = (1-alpha) * Q(t-2) + (alpha) * (Reward(t-2) + gamma * Reward(t-1) + gamma * gamma * Max( Q(t) ) ) My question: The term gamma * Reward(t-1) means that I will always take my best action at t-1 .. which I think will prevent exploring.. Can someone give me a hint? Thanks

• Prevent IE caching

  - by Parhs

  I am developing a Java EE web application using Struts. The problem is with Internet Explorer caching. If an user logs out he can access some pages because they are cached and no request is made. If I hit refresh it works fine. Also if an user goes to login page again it won't redirect him because that page is also cached. Two solutions come to my mind: Writing an Interceptor (servlet filter like) to add to response header no-cache etc. Or or put <meta> tags at each page. Which one should I do?

  - by jkranthi

  Hii all , I am trying to to click on a link after it is active which again produces a popup ( file download) after clicking.

• Unkillable console windows

  - by rep_movsd

  I'm developing an OpenGL based 2d simulation with GLUT under Visual C++ 2008, sometimes when I have an assert() or unhandled exception and break into the debugger, the GLUT display window closes, but the console window remains open.They just cant be killed!!! They do not show up with Task manager, Process Explorer or any other tool, I cannot find the window handle using the Spy++ tool either. Worst thing is they prevent my system (Windows XP) from shutting down, I have to manually poweroff (and of course I have to run chkdsk on my drives and invariably it finds and fixes minor errors after bad shutdowns) Has anyone come across such an issue?

• How to refresh to entire device's screen (Windows Mobile)?

  - by walidad

  Hi everybody, I'm working on a simple application that draws an alpha-blended picture on the screen's Device Context every 2 secs, I want to refresh the screen contents before the drawing operation (To erase the drawn pic), I have used many many trick but unfortunately, the screen won't refresh correctly, some regions still keep portions of the drawn pic I'm really frustrated from this issue :( These are the sources codes I have used, I'm using C# SendMessage(HWND_BROADCAST, WM_SYSCOLORCHANGE, IntPtr.Zero, IntPtr.Zero); // wasted time in the refreshing process is enough to keep this. UpdateWindow(HWND_BROADCAST);// does not work at all! InvalidateRect(IntPtr.Zero,IntPtr.Zero,true); // the same goes here. SendMessage(HWND_BROADCAST, WM_PAINT, IntPtr.Zero, IntPtr.Zero); // pfffff ! SendMessage(HWND_BROADCAST, WM_SETTINGCHANGE, new IntPtr(SPI_SETNONCLIENTMETRICS), IntPtr.Zero); // trying to refresh the explorer, no resutl I used also EnumWindows and call back , very slow and does not fit my case. I wanna refresh the whole screen Help please! Regards Waleed

• What happens to an ActiveX control (COleControl) after the call to OnDestroy() ?

  - by richj

  I have an ActiveX control written in C++ that runs in Internet Explorer 8. Most of the time (approx 90%) when the tab or browser containing the control is closed, there is an access violation like this: The thread 'Win32 Thread' (0x1bf0) has exited with code 0 (0x0). Unhandled exception at 0x77b3b9fd in iexplore.exe: 0xC0000005: Access violation reading location 0x65007408. The access violation occurs after the call to OnDestroy() but before the call to the control's destructor. The debug output says: No symbols are loaded for any call stack frame. The source code cannot be displayed. None of my code is present in the stacktrace, although perhaps the heap was corrupted at some earlier point during execution. What lifecycle events does an ActiveX control receive between the call to OnDestroy() and the control's destructor?

• Working local and upload on save in Eclipse with Aptana

  - by Saif Bechan

  Currently I am working in Dreamweaver for my web project. The way I work is open local files, and when I save the files are uploaded via FTP to my server. This works great because I have the same files local and on the server, and I don't have to move the files around a lot. Is this possible in eclipse with Aptana? I have tried working with RSE(remote system explorer), but then I only work with the remote files. I have also tried the normal Aptana FTP features, but there is no 'save on upload' feature. Does anyone have some recommendations for me?

• How to share WinForms and code between 2 projects

  - by Richard Bysouth

  Hi I have a working Windows Forms app (split into an EXE and a few DLLs). Now I've been asked to look at creating another app (MyAppLite) that has only a very small subset of the functionality. Think of it as similar to MS Word Viewer vs. MS Word. Everything that I need to build MyAppLite is contained in the main solution - essentially I need to use a couple of the WinForms and whatever bits in the DLLs they call into. What would be the best way to do this? I was thinking of creating another Project in my solution for MyAppLite, then adding the necessary source files as links (using Add Existing Item Add As Link in Solution Explorer). I definitely wouldn't want to maintain 2 copies of the source code. FYI it's a .NET 2.0 VB app, using VS2008. thanks Richard

• ASP.Net & 960.gs Integrating the .css files into a new project.

  - by Baxter

  I've got a full layout designed using 960.gs and am wanting to use it in a ASP.net website but i'm getting warnings such as: "Warning File 'css/Reset.css' was not found." "Warning File 'css/Text.css' was not found." "Warning File 'css/960.css' was not found." "Warning File 'css/Base.css' was not found." I've tried adding a new similarly named folder to the solution explorer and 'add existing item' to add them in but it still seems to cause warnings and intelisense isn't recognising any of the 960.gs classes. Is there a recommended workflow for importing all of this in? I should add that it works perfectly well on the local development server and on the webspace, it's seemingly just VS that's complaining.

• Macros no longer working in VS2005

  - by NPVN

  I'm using VS2005 on Vista. I'm using some macros, but now they have suddenly stopped working. No error messages of any kind. I am not aware of having done anything that could trigger this. I have made sure that "Allow macros to run" is checked in Tools-Options-Addin/Macro Security. I have tried running the macros from a keyboard shortcut, from the Macro Explorer, and from the Macros IDE, all in vain: The little spinning icon displays shortly (<1 sec) and then disappears without the macro being executed. I have tried putting a breakpoint on the first line of the macro and then executing it from the main IDE, with no effect (the breakpoint isn't hit). I have tried the same from the Macro IDE: The state changes to "running", but the breakpoint isn't hit. I have to break the execution manually. Any ideas?

• Type-safe, generic, empty Collections with static generics

  - by Droo

  I return empty collections vs. null whenever possible. I switch between two methods for doing so using java.util.Collections: return Collections.EMPTY_LIST; return Collections.emptyList(); where emptyList() is supposed to be type-safe. But I recently discovered: return Collections.<ComplexObject> emptyList(); return Collections.<ComplexObject> singletonList(new ComplexObject()); etc. I see this method in Eclipse Package Explorer: <clinit> () : void but I don't see how this is done in the source code (1.5). How is this magic tomfoolerie happening!!

• Setting up a SQL Membership Provider and attaching the MDF file in Visual Studio 2008

  - by aubreyrhodes

  I'm trying to set up a SQL Membership Provider for an ASP.NET MVC 1.0 and I'm having problems setting up the tables and stored procedures in the database. I've tried attaching both the applications current database and a blank database to my local SQLEXPRESS instance (using SSEUtil) and then running the aspnet_regsql wizard against them. When I detach the mdf file and try to load it in Visual Studio 2008, the data connection in the server explorer shows that the database has no tables or stored procedures. Am I missing a step or something here? I've been having a heap of trouble with compatibility between Visual Studio and SQLEXPRESS.

• How to deal with symbolic links when going between Linux and Windows?

  - by Jesse Beder

  I have a django project that runs on a Linux server, and I've been working on it both on Linux and OS X. I've noticed that some of the pages are a bit off, to put it politely, in Internet Explorer, and so I checked out the subversion repository on Windows and tried to run a local server. My media directory has symbolic links to all of the media from each different app, and obviously Windows doesn't know what to do with them. I could simply hard-copy or link everything manually in Windows, but then I wouldn't be able to check that in (since the site runs on a Linux server), so it'd be a pain in the neck. What is typically done in this case?

• Win32 API Programming - Is it worth ?

  - by nXqd

  Now I code win32 api windows explorer . But it seems quite hard to me.I've a month to do it. But through the time I code, I wonder is it worth that I code win32 api ? . When we can create GUI easily with MFC or even easier with C#. What should I do ? 1- Keep coding with win32 api to deeply understand about them. 2- Just learn and code some programs to understand how they work. Can you determine how many time does it take in each choice ( or how many projects ). Thx for reading, as a 2nd student of IT University I really want your advice in this. My purpose is becoming a good and effective programmer :) PS: recommended books are really appreciated.
