Hi Doug,

Could this thread be helpful?

and this lesson

Only for Livecode "windows"/stacks though

Failing that, using FFI with C would do it

You need to get the handle of the window

via enumwindows (abou 10 ways of doing it)

then call

This pdf (aboutvisual  foxpro winapi access ) give all manner of calls and
calling structures which should help with FFI - I'm going to have to have a
go at FFI  soon.

I did this with a Visual Foxpro routine over a decade ago - but I've been
to bed since then so hopefully one  of the clever cloggs on here could do
to give us all a good template example for accessing windows apis  via FFI
and C - Go on mark/panos/Ali  - in between bites of your sandwiches.
a 15 minutes slot on LC Global?

Regards Lagi
