Killing a Secondary Thread

G'Day!
Well, in 16-bit MFC 1.5+ there are no threads, but there is a
"PostRegisteredMessage" for inter-application communication.
Offers the advantage of something akin to an interrupt-driven
interprocess protocol rather than polling a semaphore.  I'd be
interested to know if "Post etc." is generic, or restricted to
Windows 3.1.

It's a distant kin!  Posting messages does _not_ interrupt the target 
process; the target process must still poll the message queue if it wants to 
eventually get the message. The message won't be delivered until the polling 
happens.

There is no PostRegisteredMessage() function in the Win32 API.

Jim;

I just implemented an "Event Logger" that used that technique to allow
16-bit applications to communicate with a 32-bit application under Windows
NT 3.51.  Thus you may assume it is generic to all the current Windows'
operating systems.

A 'registry key' must be used to create a 'registered' user defined message.
Also you must implement an PreTranslate member function in order to process
the message.

The technique isn't similar to an interrupt service rather consider the
receiving process to be 'receiver' driven.  In other words the process is
idle until a message arrives in it's que.
