Form's transparent properties will work just in WinXP. I want to do it in all Windows (putting a transparent image on it and the form's shape would be like the image). and how can I drag my form with any part of its surface (means I can drag it with not just its header but any part).

thank you

hello  mehdi_m, I would use a windows system Region to do a Shape for a Form from a bitmap in systems older than Win 2000, , , But,  it is NOT so easy to get a region from a bitmap, you might look at this EE question , which will show you code to do this -

if you want to move the form with the mouse then get the  OnMouseDown  event for that form and use this code-
procedure TForm1.FormMouseDown(Sender: TObject; Button: TMouseButton;
  Shift: TShiftState; X, Y: Integer);
begin
if (Button = mbLeft) then
  begin
  ReleaseCapture;
  Form1.perform(WM_SysCommand, $F012, 0);
  end;
end;
