1.设置对话框大小：
1 CRect temprect(0,0,1640,1480); 2 CWnd::SetWindowPos(NULL,0,0,temprect.Width(),temprect.Height(),SWP_NOZORDER|SWP_NOMOVE);
2.使对话框全屏显示：
1 //得到显示器大小 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);
