HwndSource.FromHwnd Method (IntPtr)
Returns the HwndSource object of the specified window.
Assembly: PresentationCore (in PresentationCore.dll)
This method is not available in the Internet security zone, or for partial trust in general.
You can use this method to return an HwndSource for a window that is not explicitly an interoperation window. The procedure for this is:
Pass that HWND value as a parameter to.
This technique can be useful if you then want to add general AddHook message processing to the window. However, whenever you create an HwndSource, you are also responsible for destroying it. This is true even if the Application object for an application HwndSource is disposed. For more information, see Remarks on HwndSource.
