getWindowDC vs Process.Handle

[Sephi berry via .NET 247]

Hi
I'm having this problem of accessing the handle of a window.
I retrive it by:
Dim procs As Process() = Process.GetProcessesByName("ArcScene")
dim intHWND1 IntPtr = procs(0).Handle

and get a number BUT when i try to get a screenshot with
...
Dim hdcSrc As IntPtr = User32.GetWindowDC(handle)
...
I get Zero !

Any suggstions would be appriciated,
thanks
Sephi

Notice that 'procs(0).Handle' returns a process handle, but
'GetWindowDC' requires a window handle. You can use
'procs(0).MainWindowHandle' to get a handle to the process' main window
handle, and then pass this handle to 'GetWindowDC'.
