How to work with CAsyncSocket in multitasking environment?

[Dilshod Nabishev]

I'v created CAsyncSocket object and connected it in main thread. I started "watchdog" thread and in the case of broken connection i want to reconnect. All operations in "watchdog" result in unhandled exception, but the object is correct. May be threre is some rule in working with CAsyncSocket object from other thread?

Thanks

This is about the 50th time that this question has come up in the last month so once again.....

You can't pass most objects derived from CObject around between threads. You'll have to do some kind of message passing instead.

You certainly can't do CWnd and derived classes and I bet you can't do CAsyncSocket either.

However, you can create your own sockets using WinSock and pass their handles around between threads which is what I always do.

CAsyncSocket (again for the 50th time) is a bit rubbish to be honest and isn't reliable at all.

If socket S was created by thread A, then the socket S must also be closed by thread A. It would crashed it thread B trying to close S.
