My comment:
The
GetFocus
function retrieves the handle to the window that has the keyboard focus.
If you call this procedure from a form you will get an image of this form on the clipboard.
Being called from the main VFP window, with no other forms running, this procedures copies to the clipboard the whole main window itself.

An article
How To Copy the Screen or Active Window to the Clipboard from Visual Basic
published on Microsoft Help and Support page describes a different approach -- the picture of the whole screen is sent to the clipboard by virtually pressing (through the
keybd_event
call) PrtScr key.
