Dear all,
I'm going in a project in which I'll need to interface

with an external H/W device. I need to get interrupt

from this external H/W through the parallel port(i.e.

IRQ7), I have accomplished this job before using

Assembly but now I need to make it on Visual C++ 6. I

have found many code samples on the web but they only

work on Borland compiler!!! How to make this on Visual

Studio enviroment.
I also need to make a specific job periodically and that

requires to make a Timer interrupt, the timer should be

running in the background not the main process, how

could I make this also?
I need to know the headers to include and function names

and any reference to read about this part.
I'm using WinXP but if there is a solution on Win98 I

can transfer to it.
Al ast thing, I needed to use the parallel port for

interfacing this external H/W so I'm using
_outp(add,data) but this doesn't work on WinXP because

of the protection set on these ports, how to avoid this?
Thanks in advance

Buy a third-party parallel port driver/SDK or write your own and enjoy!
