As it happens, the correct answer is probably, "No, not
in any *current* version of IDL." :-)
Cheers,

P.S. Let's just say if you absolutely need this capability
you may want to be sure your maintenance contract is up
to date. :-)

Always the pessimist....
I am working on finishing up a win32 only dlm that provides access to
keyboard, mouse and gameport devices using direct input. The only drawback
is that you poll the devices. I run most all of my GUI apps with a timer so
this is exactly what I want but it probably isn't the way most people
structure their apps. I should be finished with it by the end of the week.
This does bring us to a question I was mulling. If I wanted to enable
device input to trigger events in IDL, how does a dlm callback into IDL?
