    //  -------------------------------------------------------------------------------
    //  The following is a general note that applies to all programming languages:
    //  -------------------------------------------------------------------------------
    //  Your application can keep a reference to the task object and periodically check back later to see if it's finished.
    //  If your programming language is one that supports callbacks, then the TaskCompleted callback can
    //  be setup to be called when the task completes.  (See the "Async" category on example-code.com for more information.)
    //  
    //  NOTE: This is very important:  A TaskCompleted callback runs in the background thread.  
    //  (All callbacks from an async task, such as AbortCheck, PercentDone, ProgressInfo, etc. are in the background thread.) 
    //  An application that uses TaskCompleted must be very careful.  
    //  For example, user interface elements (such as labels, text boxes, etc.) may not be directly
    //  accessible from a background thread, and could crash the application if directly accessed.  Also, attempting to debug
    //  code running in a background thread from an IDE, especially an older IDE (such as VB6) is likely to crash the IDE.
