Thanks, I will try that and I'm pretty sure that will work. I need to find
some documentation
on the MSAA object model so that I can learn about methods such as the
accValue one.
If you know of any simple documentation for MSAA or a good place to start
please let me know.
I tried sendmessage but I came to the conclusion that when the sendmessage
call returns
something via the Lparam variable, then it can't be used in JAWS. There
doesn't seem to be
a mechanism to capture this information. When Lparam doesn't play a role in
the sendmessage call, then it seems to do OK in JAWS. Others more
experienced with using
SendMessage may have more to say about this but that's my assessment.
