程序内部读取网络信息, 该代码可以通过网络提交验证密码再进行判断... 

CInternetSession mySession(NULL,0);
 CHttpFile* myHttpFile=NULL;

 CString myData;
 CString myUrl;
 myUrl = "http://127.0.0.1/yanz.php?name=" + m_myName + "&password=" + m_myPassword;
 myHttpFile=(CHttpFile*)mySession.OpenURL(myUrl);
 while(myHttpFile->ReadString(myData))
 {
             m_SiteInfo = myData;
 }
 
 if( m_SiteInfo == "hao" ){
         CDialog::OnCancel();
 }else{
         AfxMessageBox( "密码错误", NULL, MB_OK );
 }

 myHttpFile->Close();
 mySession.Close();
