1.獲取螢幕的解析度

CRect rectWind;  

int iWidth = rectWind.Width();  

2.使對話方塊全屏顯示

  //得到顯示器大小
2     int   cx,cy;
3     cx   =   GetSystemMetrics(SM_CXSCREEN);
4     cy   =   GetSystemMetrics(SM_CYSCREEN);
5     //再用MoveWindow
6     CRect   rcTemp;
 
7     rcTemp.BottomRight()   =   CPoint(cx,   cy);
8     rcTemp.TopLeft()   =   CPoint(0,   0);
9     MoveWindow(&rcTemp);
