In Vista and later, if an app becomes unresponsive, the Desktop Window Manager is able to handle redrawing it when necessary (move a window over it, drag it around, etc.) because it has kept a pixel buffer for it. Windows also tries to detect when an app has become unresponsive after some timeout, and tries to make the best of the situa...

Hi ! I wrote a free game a few years ago: http://www.walkover.org. For the lobby and menus, it uses normal dialogs like win32. When the actual game starts it uses OpenGL. Now, on Windows 7, when the actual game starts, it switches windows aero glass off and switches it back on when the game is over. Is there something I can do to pr...

How do I flag an app in Windows Vista/Seven to disable desktop composition thru registry or NSIS script? Normally it´s done in Compatibility settings in app´s properties. ...
I want to create a desktop manager that takes informations of all running applications including states and screenshots to display and manipulate them in my virtual space (probably in 3D). It can be considered as another layer of abstraction on top of Windows itself. Because many native Windows Vista/7 features like Flip 3D and Live Thu...
I'm looking to write a FOSS "Alt+Tab" replacement (window switcher) for Windows, since there are a few features I feel it's (still) lacking; but I'm noticing two quirks I can't seem to fix: #1. (Somewhat Unrelated) In the default Windows 7 window switcher, one computer allows left clicking on a thumbnail to focus the window; however on ...
My app has an option to disable aero by calling DwmEnableComposition(0) before capturing a screen image. As you know, disabling aero makes the screen go black then return to normal afterwards. On different PCs this might take 2 to 3 seconds depending on how fast the system is. Is there a better way of determining if aero has fully disa...
I am confused by Delphi 2009/2010 support for the Aero Theme Glass features in Windows, and by what, exactly DoubleBuffered means, and what it has to do with Aero glass. I have found that DoubleBuffered is not only a property in the VCL, it also is found in .net WinForms. Initially I wondered if it set some kind of window style bit use...

As we know, several modern applications (IE9, Firefox 4, Chrome, Paint.NET, etc.) use DwmExtendFrameIntoClientArea for the Aero glass effect. What type of applications should you really use this for, though? For browsers I can understand minimizing as much extraneous space as possible, but really, what's the point? Why not just create t...

Hi, I'm doing a windows application using dwmapi.dll on C# and it's not working in windows XP because XP didn't support Desktop Windows Manager API (dwmapi.dll).

On MSDN's DWM Thumbnail Overview they specifically state: Note DWM thumbnails do not enable developers to create applications like the Windows Vista Flip3D (WINKEY-TAB) feature. Thumbnails are rendered directly to the destination window in 2-D. So what API can be used to create applications like the Windows Vista Flip3D? ...
