Hiding/showing the Windows taskbar

Answer:

Use these functions to hide or show the Windows taskbar programmatically from your 
Delphi application:


1   procedure hideTaskbar;
2   var
3     wndHandle: THandle;
4     wndClass: array[0..50] of Char;
5   begin
6     StrPCopy(@wndClass[0], 'Shell_TrayWnd');
7     wndHandle := FindWindow(@wndClass[0], nil);
8     ShowWindow(wndHandle, SW_HIDE); // This hides the taskbar
9   end;
10  
11  procedure showTaskbar;
12  var
13    wndHandle: THandle;
14    wndClass: array[0..50] of Char;
15  begin
16    StrPCopy(@wndClass[0], 'Shell_TrayWnd');
17    wndHandle := FindWindow(@wndClass[0], nil);
18    ShowWindow(wndHandle, SW_RESTORE); // This restores the taskbar
19  end;
