问题 Context from Kenny Kerr's blog: Windows Vista introduced a service called the Desktop Window Manager. The name was and continues to be misleading. Think of it as the Windows composition engine or compositor. This composition engine completely changed the way application windows are rendered on the desktop. Rather than allowing each window to render directly to the display, or display adapter, every window renders to an off-screen surface or buffer. The system allocates one such surface per

问题 I have a weird error I'm trying to debug with no luck. I have subclassed hwndhost showing some content, I have the following function in that class to set to fullscreen: private void SetFullScreen(bool enable) { if (enable) { fs = new Window(); fs.ResizeMode = ResizeMode.NoResize; fs.WindowState = System.Windows.WindowState.Maximized; fs.WindowStyle = System.Windows.WindowStyle.None; fs.Topmost = true; fs.PreviewKeyDown += delegate(object sender, KeyEventArgs e) { if (e.Key==Key.Escape)

How can I convert Win32 mouse messages to WPF mouse events?

问题 I have a Win32 (OpenGL) control that I need to embed in our WPF application. It must respond to, and propogate, mouse and keyboard events. I've created a HwndHost derived instance to host the native window and have overridden the WndProc function in this class. To propogate win32 messages to WPF I handle specific mouse messages and map them to WPF events, then use the static InputManager class to raise them. The problem is, when I go to handle them the mouse coordinates are messed up. Heres a

Custom dwm drawn window frame flickers on resizing if the window contains a HwndHost element

问题 I've been thinking about this for a couple of days but I think I lack some basic understanding of how windows and wpf work internally to figure this out. The problem is this: I created a window that should let me draw wpf controls on an aero title bar (like office). This works fine as long as I don't add a Hwndhost element to the window, in this case whenever i resize it the frame and the HwndHost start to flicker pretty badly (other elements seem to render properly). I also tried using the

Hosting external app in WPF window

We are developing a layout manager in WPF that has viewports which can be moved/resized/etc by a user. Viewports are normally filled with data (pictures/movies/etc) via providers that are under our control in the layout manager. My job is to examine if its also possible to host any external Windows app (i.e. notepad, calc, adobe reader, etc) in a viewport. I encounter a number of problems. Most resources point to using the HwndHost class. I am experimenting with this walkthrough from Microsoft itself: http://msdn.microsoft.com/en-us/library/ms752055.aspx I've adapted this so the list box is
