（(C***View)(AfxGetMainWnd()->GetActiveView())）->Invalidate()
其中C***View替换为告局局你自己的View类的名字。
2、调用Invalidate()只是实现了刷新显示而已，至于如何实现图片大小的更新，仍需要其他代码（比如在腊枣View类中添加代表图片大小的成袜让员变量，在OnDraw()中按照成员变量绘制图片，在OnOK()中更新View成员变量的值）。

1.首先你应该把DlgConnect s传巧迟给多线盯滚程函数如下：
hThread=CreateThread(NULL,
0,
(LPTHREAD_START_ROUTINE)ThreadFunc,
pParam,／／这里改为(void*)(&s)
0,
&ThreadID)
2.在函数孝则李UINT ThreadFunc(LPVOID pParam)中
删除掉DlgConnect s
把s.DoModal()
改为
(DlgConnect *)(pParm)->DoModal()
