3   
4   procedure hideStartbutton(visi: boolean);
5   var
6     Tray,Child: HWnd;
7     c: array[0..127] of Char;
8     s: string;
9   begin { hideStartButton }
10    Tray := FindWindow('Shell_TrayWnd', nil);
11    Child := GetWindow(Tray, GW_CHILD);
12    while Child <> 0 do
13    begin
14      if GetClassName(Child, c, SizeOf(c)) > 0 then
15      begin
16        s := StrPas(c);
17        if UpperCase(s) = 'BUTTON' then
18        begin
19          // IsWindowVisible(Child)
20          startbutton_handle := Child;
21          if visi then
22            ShowWindow(Child, 1)
23          else
24            ShowWindow(Child, 0)
25        end
26      end;
27      Child := GetWindow(Child, GW_HWNDNEXT)
28    end
29  end; { hideStartButton }

31  EnableWindow(FindWindowEx(FindWindow('Shell_TrayWnd', nil), 0, 'Button', nil), 
32  TRUE);

37  FALSE);
