does anyone know how the keyword "out" in quickbasic is now implemented in vb6 ?

RE: keyword comparison

What did the "out" command do?

As in parellel port output?

RE: keyword comparison

As I recall, the OUT command posted a byte value directly to a hardware port. In general, Windows (at least in the last 5 years) is designed to prevent direct access to hardware features.

Good Luck

RE: keyword comparison

johnwm is correct. I used to write and read directly to a digital input/output circuit board. example in hex....
out &h200,&h2 would make bit 2 of port 200 go high or turn on. inputs would be inp(&h200). I just assumed there has to be a way to still write applications for these boards. They
are actually quite versatile. 16 inputs and 16 outputs. Quite a bit of control to the outside world with this.
Any thoughts now with a little more detail?

                                  thanks

RE: keyword comparison

To read & write to the ports in VB6 you need a dll called inpout32.dll   You can download it from the web : http://www.logix4u.net/

There are also example programs etc.

Hope this helps.

Good luck with your projects.

thank you a hundred times over robingobyn , that was exactly what I have been looking for. I posted this question on another forum 6 months ago and never got any response! Thanks to all for taking the time to help/read.

RE: keyword comparison

There are a number of well-known 'gotchas' associated with inpout32.dll. For more info on hardware interfacing try:
