My program is running for a period of time will pop up "operation timed out" mistakes, I doubt that is the function of the session. The OpenURL function quote, if is the function of, is there a way to not let it play out?

I have catch this exception, why still prompt box? How to solve

Capture the abnormal after

You are to say to catch exceptions, calls e - & gt; Delete () this?

Comment out LOGERROR (" CInternetException "); Take a look at

CodePudding user response:

The system prompt operation, overtime? Rather than the program prompts you, don't know if the original poster is the problem

CInternetSession OpenURL, if the network is not, will be stuck here, this interface will be stuck more than 10 seconds

Session. SetOption the building through the set timeout, you think really works? I tried to use, or the card more than 10 seconds
