MFC supports Two types of threads 1. Worker thread and 2.
user interface thread.
Worker Thread : Does not need user intervention while
running. example background printing etc...
User interface thread : Needs user interface while running
like needs input from user to process further etc....

AfxBeginThread() is used to Create both worker and User
interface thread. to differentiate worker and user-
interface thread AfxBeginThread has minor changes.
