Windows will make a window a full-screen-sized (covering the Task Bar) if
the window's style is WS_POPUP and it's sized to the dimensions of the
screen.  If you're using a TForm-type window, you can effect this like so...

  BorderStyle = bsNone;
  WindowState = wsMaximized;
  SetBounds(0, 0, Screen->Width, Screen->Height);

If you're not using the VCL, you can do the following...

  // get the dimensions of the screen
  // (see also http://tinyurl.com/qmcw)
  HDC const hScreenDC = GetDC(NULL);
  SIZE const SScreen = {
    GetDeviceCaps(hScreenDC, HORZRES),
    GetDeviceCaps(hScreenDC, VERTRES)
    };
  ReleaseDC(NULL, hScreenDC);

  // change the window's style and then resize
  HWND const hWnd = // handle to the window
  SetWindowLong(hWnd, GWL_STYLE, WS_VISIBLE | WS_POPUP | WS_MAXIMIZE);
  SetWindowPos(hWnd, NULL, 0, 0, SScreen.cx, SScreen.cy,
    SWP_NOZORDER | SWP_FRAMECHANGED); 

Good luck,
