Windows API Guide: FillRgn Function

---

Declare Function GetDesktopWindow Lib "user32.dll" () As Long

Platforms: Win 32s, Win 95/98, Win NT

GetDesktopWindow returns a handle to the desktop window. The desktop window is the window that makes up the desktop of the computer -- that is, the screen. If the function fails, it will return 0 instead of the handle.

Example:

' Find the device context of the desktop ' The handle to the desktop is needed to find the device context Dim deskhwnd As Long  ' handle to the desktop Dim deskhdc As Long  ' device context to the desktop Dim retval As Long  ' return value deskhwnd = GetDesktopWindow()  ' get the desktop's handle deskhdc = GetDC(deskhwnd)  ' get the desktop's device context ' You could put any code that works with the desktop here retval = ReleaseDC(deskhwnd, deskhdc)  ' free up resources associated with the device context
