I once saw a very short example of moving a form with the mouse. It's the same like 
moving the form with the mouse in the caption of the form, but now it is moveable 
with the mouse in the client area. Has anyone an idea how to do this?

Answer:

In the private declarations of the form add this message handler:

1   private
2   { Private declarations }
3   
4   procedure WMNCHitTest(var M: TWMNCHitTest); message WM_NCHITTEST;
5   
6   //Then add this procedure
7   
8   <!--CS-->procedure TForm1.WMNCHitTest(var M: TWMNCHitTest);
9   begin
10    inherited;
11    if M.Result = htClient then
12    begin
13      {Client area is hit - but state it is the Title Bar}
14      if ((m.ypos - HelpWin.top) < HelpWin.height) then
15        M.Result := htCaption;
16    end;
17  end;
