Well it sounds as though this is what I am after, but it doesn't work. (I
changed the line to GetWindowsDC(0) but it doesn't know that... took GetWindowDC
(0) OK but the TImage didn't have anything in it when the form came back.
Here's the section of code - perhaps I've misunderstood how to use it.
procedure TForm1.GetScreen1Click(Sender: TObject);
Var
theDC : HDC;
begin
Form1.Visible := false;
theDC := GetWindowDC(0);
Image1.Canvas.Handle := theDC
Form1.Visible := true;
end;
As you can see, I'm trying to get the form out of the way to display what is on
the screen underneath, then calling GetWindowDC(0) and then making the form
visible again.
I want the form to come back up with a copy of the desktop or whatever other
application is running underneath showing in the TImage.
As I said, I can press the printscreen key manually before running the program
then use ASSIGN method to get the image into the TIMage and that works fine -
just can't do it from the program yet...
