如何用事件实现在网页加载完成后，执行后面的代码

Question

void   CTestNavigateView::OnNewWebPage()  
{
                //   TODO:   Add   your   command   handler   code   here
                Navigate2(_T( "http://192.168.34.120/DMS/index.jsp "));
                m_NavigateEvent.Lock();                
                MessageBox( "Hello   DMS ");                  
}

void   CTestNavigateView::OnDocumentComplete(LPCTSTR   lpszURL)  
{
//   TODO:   Add   your   specialized   code   here   and/or   call   the   base   class
m_NavigateEvent.SetEvent();  
CHtmlView::OnDocumentComplete(lpszURL);
}
OnNewWebPage()是一个工具栏按钮的执行函数，我想在Navigate2(_T( "http://192.168.34.120/DMS/index.jsp "));加载完页面后再执行MessageBox( "Hello   DMS ");     所以在中间用一个event变量锁定。然后希望在
CTestNavigateView::OnDocumentComplete   中将event解锁从而达到目的。但是在实际执行时，并没有跳转到OnDocumentComplete   中执行解锁，而是一直停在m_NavigateEvent.Lock();     这一句了。谁能告诉我为什么没有跳到OnDocumentComplete   中呢？
如果没有m_NavigateEvent.Lock();     这一句，网页和消息框是可以正常打开的，但网页还没加载完，消息框就弹出来了。
如果用多线程要怎么实现?我试过，没有成功。

我想用CEvent来实现，应该是要用多线程了。两个进程访问同一个CEvent变量，一个进程加锁，另一个进程解锁。可是为啥调用了Navigate2就是不能跳到OnDocumentComplete(）中呢？应该怎么写？

另一段代码，数字转换的,看看有什么bug吗？
