Why don't you do a debug session and single-step the code?
Then you will know exactly what's going on, and find out where the problem is.

Then please tell us this:
What is your specific problem? What's not working?
What statement dosen't work?
You can't expect anyone to copy your code, clone your database e.t.c. and then come up with a solution.

HI,

I am using a class derived from CSocket in my application. As when the Socket is sending or reciveing a data and the data not came then it gets blocked. There is a CancelBlocking method in the CSocket.

But how can I programaticaly handle it, when one of the application Client or Server stops sending or recieving dta then other application should not gets blocked.

any idea / link

Thanks

Regards.

Try the CAsyncSocket Class.
