None = OpenClipboard(hWnd)
The OpenClipboard function opens the
clipboard for examination and prevents other applications from modifying
the clipboard content.
Parameters
hWnd=None : PyHANDLE
Integer handle to the window to be associated with the
open clipboard. If this parameter is None, the open clipboard is associated
with the current task.
Comments
OpenClipboard fails if another window has the clipboard open.
An application should call the CloseClipboard function after every
successful call to OpenClipboard.
The window identified by the hWnd parameter does not become the
clipboard owner unless the EmptyClipboard function is called.
