Hello,

I want to write a VB6 program using the LPT port. I found one or two
dll's i can use. However these dll's are not interrupt capable. I want
to use an interrupt when one of the control lines changes (for
instance strobe) in stead of polling this signal all the time (the
computer goes to max speed while it is just polling one signal!).
Also the signal might change only for a very brief time so when the
WinXP decides it needs to do something much more important it might
miss this signal all together.
So my question: Does anybody know a dll/ocx for the parallel port with
interrupt?

Poll it within a Timer Event
Neila, Thanks for the suggestion.
This is however not possible. I have to catch a 1 msec pulse of which
i do not know when it will happen. Also when it happens the next pulse
might be available in (i expect) 20-100 msec.

If you don't mind losing the odd pulse (say a mouse or an encoder used as a volume etc. control), just ignore cycles where there's more than 1 state change, and resynch the process. ...
