A little description of what to use AttachWindowMessage for

[RicksPlace]

Hi: Since my VB.net External script is not processing Window Events - actually 
it did once but never again through several tests it just wouldn't do it again 
at all. I was wondering what the 
AttachWindowMessage Method of the WE Application object is used for.It sort of 
sounds like it might be a counterpart to the MSAA WatchEvents thingy but I'm 
not sure. The syntax examples are in VBScript in the manual as far as I can 
tell so I'm not sure this is for Hosted or External scripts and what it 
actually does.
Thanks:
