Matt,
I'll take a look at this.
Thanks, Steve

I'm not sure why anyone is mentioning screen scraping and OCR. You are
right to think that you can just pick up the text entry events sent to
the window. You might want to look at AutoHotkey
(http://www.autohotkey.com/) you can use this to either "tee" the user
input to your terminal program /or/ inspect the labeled elements of
the windows program by name (a far better idea). I used something like
this to interface some windows based software for a laser scanner with
a low level embedded robotics chassis where I needed to send some
stuff over a socket from the command line. It has a nice macro record
feature, so you can record cycling through the entry boxes and then
save this macro. Open it up in an editor and just add a bit of foo to
dump it into your terminal program, then your users will just have to
run your macro with the window open, or you just set the macro to
trigger on "title change" (or whatever) of the window for the
application of interest.
http://rosettacode.org/wiki/Category:AutoHotkey might help you get up
and running too.
Best,
Matt
