I have a very simple question about how CWinThread works and where is the entry point everytime I called ResumeThread(). I’m looking for an entry that looks similar as “main” function where I can perform some operations and branches.

I’m also wondering how to end or kill running threads at any point from different thread. Where should I put AfxEndThread()? or simply call pThread->ExitInstance()?

My last question is, if i want to make multiple threads, how do I organize them in Standard Template Library (STL) using vector?

Thank you.

    The primary entry point for a class derived from CWinThread is the virtual Run() function. However, there is also an InitInstance() function which is called beforehand, and an ExitInstance() function called afterwards.

    You should never call ExitInstance() yourself. Instead, call AfxEndThread, or just return from Run().

    If you really want to put your threads in a std::vector<> then use a pointer as the class is not copyable, and the instance is deleted automatically by MFC when the thread exits.

    Edit: As David pointed out, you generally don’t want to use SuspendThread and ResumeThread in application code. Start your thread with AfxBeginThread if you’re using MFC.
