How can I get the Hdc of screen in VB.net or C#? It seems to be strange in
VB.net!!
I know in VB6,I can use getdc api to get Hdc of screen,but in Vb.net no such
a function. even under the graphics class the getHdc() is invisible to the
programmers.

Any ideas?
Thanks in advance!!!

Use interop and the GetDesktopWindow() and / or GetDC(..) with a null
parameter.

Does it mean some can not be achieved by the class provided by .net framework?
So u can not use .Net framework to get a dc of screen. Have to call win32 api.
Anyway,thanks a lot!!!
