Remarks
This member function queues a request for execution by the worker thread. The parameters of this member function are queued (in a CMsg object) and passed to the CMsgThread::ThreadMessageProc member function of the worker thread.
This member function returns immediately after queuing the request and does not wait for the thread to fulfill the request. The CMsgThread::ThreadMessageProc member function of the derived class defines the four parameters.
This member function uses a multithread safe list, so multiple calls to this member function from different threads can be made safely.
