# Imagine we've sent this email via SMTP, and now we want to 
# save the email to our "Sent" mailbox.  On GMail, the mailbox name
# for sent email is "[Gmail]/Sent Mail".

# Call the async version of the AppendMail method to return a task object.
$task = $imap.AppendMailAsync("[Gmail]/Sent Mail",$email)

# Schedule the task for running on the thread pool.  This changes the task's state
# from Inert to Live.  The task is now running...

# -------------------------------------------------------------------------------
# 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.
