Call this function to get a pointer to the CWinThread object representing the currently executing thread.
CWinThread* AfxGetThread( );
Pointer to the currently executing thread; otherwise NULL.
Must be called from within the desired thread.
If you are porting an MFC project calling AfxGetThread from Visual C++ versions 4.2, 5.0, or 6.0, AfxGetThread calls AfxGetApp if no thread is found. In Visual C+ .NET and later, AfxGetThread returns NULL if no thread was found. If you want the application thread, you must call AfxGetApp.
//Print the current thread ID in the Debug Window TRACE(_T("Current Thread ID = 0x%X\n"), AfxGetThread()->m_nThreadID);
