CreateThread() executes ONLY once ... ?

**SyntaxBubble** · 11-12-2003

Hello. I am working on a multi-threaded application using sockets, and I am using the CreateThread() function. BTW, I am using MS Visual C++ 6.0 Standard on a Windows 98 machine, using MFC for this app. Anyhow, I added a 'AfxMessageBox("Test");' to my thread function, and it is only called once, and then ends the thread. I think it has something to do with WaitFor(Single/Multiple)Object(s), but I tried those. It says the thread's handle needs to have the "SYNCHRONIZE" right, but I don't know how to do that. If you can, please offer any help.

Thanks,
Matt U.

I don't use MFC, however, I am awre that MFC has it's own threading and sychronisation classes. Are you using those? If so, I don't know - don't use it! If not, should you be?

Use AfxBeginThread() to create for multithreading in MFC. Otherwise, use __beginthreadex().

Correct. One solution is an event object.

HANDLE hEvent = ::CreateEvent(...);

What else would you like it to do? Also, if you created the thread you have the SYNCHRONIZE right. But exactly what are you trying to do?

Read this.
Then come back with specific questions/problems you might have.

Here is an awsome thread wrapper class you can use too.
