A very simple code

 CInternetSession is; 
CHttpFile * file=(CHttpFile *) is the OpenURL (url); 

IE set up agent, and can be normal access to the Internet web page, the same url that can be accessed in IE and Chrome, but inside the code will not be able to access, return 12029 (unable to establish connection with the server), tried all sorts of online way to not make,

Code inside access Intranet web page is no problem, but just can not access the web page,

don't know how to set up a proxy to just go? After set up agency in IE, the code will also need to set?

The odd thing is that the code can be run for a period of time, but how also not line,
