GetOpenClipboardWindow function (winuser.h)
Retrieves the handle to the window that currently has the clipboard open.
If the function succeeds, the return value is the handle to the window that has the clipboard open. If no window has the clipboard open, the return value is NULL. To get extended error information, call GetLastError.
If an application or DLL specifies a NULL window handle when calling the OpenClipboard function, the clipboard is opened but is not associated with a window. In such a case, GetOpenClipboardWindow returns NULL.
