Question:
How do I hide the Windows Task Bar?
Answer:
First call the Windows API function FindWindow() to retrieve the
handle to the TaskBar Window, then call the Windows API function
ShowWindow() passing the predefined constant SW_HIDE.
Example:
procedure TForm1.Button1Click(Sender: TObject);
var
hTaskBar : THandle;
begin
hTaskbar := FindWindow('Shell_TrayWnd', Nil);
ShowWindow(hTaskBar, SW_HIDE);
end;
procedure TForm1.Button2Click(Sender: TObject);
var
hTaskBar : THandle;
begin
hTaskbar := FindWindow('Shell_TrayWnd', Nil);
ShowWindow(hTaskBar, SW_SHOWNORMAL);
end;
