Sample Code
-----------

      int winBorder, cxBorder, cyBorder,
          cxMargin, cxBAMargin, cyBAMargin,
          x, y, cx, cy;

      /* Get the user-defined border width */ 
      winBorder = GetProfileInt("windows", "BorderWidth", 5);
      /* It must be in the range of 0 < winBorder < 51 */ 
      if (winBorder < 1) {
          winBorder = 1;
      } else if (winBorder > 50) {
          winBorder = 50;
      }

      /* Get some internal system metrics to determine extra scaling */ 
      cxBorder = GetSystemMetrics (SM_CXBORDER);
      cyBorder = GetSystemMetrics (SM_CYBORDER);
      cxMargin = (cxBorder * winBorder) + cxBorder;

      /* Byte align the border */ 
      cxBAMargin = (((cxMargin + 7) & 0xFFF8) - cxMargin);
      cyBAMargin = cxBAMargin * cyBorder / cxBorder;

      x  = cxBAMargin;
      y  = cyBAMargin;
      cx = CW_USEDEFAULT;
      cy = 0;

      hWnd = CreateWindow(szAppName, szTitle, WS_OVERLAPPEDWINDOW,
                          x, y, cx, cy,
                          NULL, NULL, hInstance, NULL);
