when i call peer_object->Close(0) the program stop in this line like a while(1) loop. When i run it with no debug everything goes fine, but when i run in debug mode it stops in this line. Is there anything i should do before call Close? thanks..

maybe try passing DPNCLOSE_IMMEDIATE to the function instead of 0?

Thanks for the reply. But i already tried it. I think its something more complex then this.....or perhaps not..

Any other idea?
I read a post in other forum that said : "im was having the same problem and putting Sleep(1) before call Close solve it"
Is this a correct way to deal with it?
i dont think so. but......sugestions?
