Hi guys,
I'm trying to paint a string on the desktop, this works with the code below
but when a window is over the text it disappears from the desktop?
Is there some way of making sure that it stays there and is only deleted
when the application is closed?
var
Handle: HWND;
Dc: HDC;
ACanvas: TCanvas;
begin
Handle := GetDesktopWindow;
Dc := GetWindowDC(Handle) ;
ACanvas := TCanvas.Create;
try
ACanvas.Handle := DC;
BeginPath(ACanvas.Handle) ;
ACanvas.Font.Color := clRed;
ACanvas.Font.Name := 'Tahoma';
ACanvas.Font.Size := 30;
SetBkMode(ACanvas.Handle, TRANSPARENT) ;
EndPath(ACanvas.Handle) ;
ACanvas.TextOut(0, 0, "Draw some text") ;
finally
ReleaseDC(Handle, ACanvas.Handle) ;
ACanvas.Free;
end;
end;
Have a nice weekend,
Nick
