VC 判断 多Frame 网页是否加载完毕

1.手动添加两个虚函数

virtual void DocumentComplete(LPDISPATCH pDisp, VARIANT* URL);

virtual void NavigateComplete2(LPDISPATCH pDisp, VARIANT* URL);

2.声明一个变量

LPDISPATCH m_lpDisp;//用于判断网页加载是否真正完毕

 

m_lpDisp = NULL;//构造函数中初始化

 

3.具体

void CXXX::DocumentComplete(LPDISPATCH pDisp,VARIANT* URL)

{

 　　if(m_lpDisp &&(m_lpDisp == pDisp))//判断网页是否真正加载完毕,用于多Frame网页

 　　{

　　　　//if the LPDISPATCH are same,that means it is the final DocumentComplete

 　　　　AfxMessageBox("下载完毕");

 　　　　m_lpDisp=NULL;//Reset glpDisp

 　　}

}

//配合DocumentComplete,判断网页是否真正加载完毕,用于多Frame网页

void CXXX::NavigateComplete2(LPDISPATCH pDisp,VARIANT* URL)

{

　　//Check if glpDisp is NULL.If NULL,that means it is

　　//the top level NavigateComplete2. Save the LPDISPATCH

 　　if(!m_lpDisp) m_lpDisp=pDisp;

}
