响应WM_GETMAXMININFO  的消息

处理之

void CMainFrame::OnGetMinMaxInfo(MINMAXINFO FAR* lpMMI) { // TODO: Add your message handler code here and/or call default lpMMI->ptMinTrackSize.x   = 100 ;      lpMMI->ptMinTrackSize.y   = 100  ;      lpMMI->ptMaxTrackSize.x   = 200  ;       lpMMI->ptMaxTrackSize.y   =  200;    CFrameWnd::OnGetMinMaxInfo(lpMMI);}

这样的话，窗口就被我框死啦，嘿嘿

长和宽的范围都是100-200
