Parameters
- u
- Request code, defined by the client of the thread class and understood by the overridden worker thread function.
- dw
- Flag parameter to the request code.
- lp
- Data required by the worker thread as parameter or return values. This data should not be stack-based, as it will be referenced some time after completing the queuing operation.

Remarks
This member function contains a request for a CMsgThreadworker thread to act on. All the parameters are passed to the worker thread function as parameters when this message gets processed. The meanings of the parameters are defined by the client function that calls the worker thread and the derived class that supplies the worker thread's execution function.
