I tried using MFC CSocket/CFile/CArchive communication in a project about a year ago, suffered mysterious crashes and lockups in testing, and solved all problems by rewriting code with WinSock calls. I never had problems with CSocket/CFile/CArchive but I never used it for intensive tasks, just simple text back and forth. Once I tried using it for file transfers it would crash every time. Though not very portable once you send objects through. I like to convert my projects over to WinSock, just havn't got around to it yet. I would recomend that to others as well.

Oops, thanks a lot! I will digest this in upcoming days :omg:

*shrug*, yes, I've read this before... if I could only understand why it's locking I think we could use CSocket. We do use it in similar applications that doesn't communicate so much.

You are right and I agree. However, the code is 6 years old and very complex (read bad). I was just hoping someone had a solution so I won't have to re-write all this code, also risking introducing bugs. Oh, well, off we go...
