PC parallel port programming

[coolchip]

Hi,
I have to write a code in windows which will continously read data from parallel port and Simultaneously write data back as well (on different pins of the port).
Is this possible in vb 6 ? I heard vb 6 doesn't support multitasking.
if that is the case which would be a better choice ? VC++ or VB.NET ?

How to write code which will constantly monitor the changing values in real time ?

Thanks in advance

Does anybody have the full version of TVicHW32 ?

Hi, Auther, do you have any experience about how to access JTAG via parallel?

You can write a callback for the multimedia timers service of windows in VC and by the use of a driver such portalk you can monitor the parallele port an handle it during the interrupt.
I wrote a software for data acquisition in this way.

Try using PortTalk which you can get from

:lol:
I did a program that send bits to the parallel port... and graphically show the pin that have 1 and 0, if you send 5v (a bit 1) to any pin you will to see on screen.

I attach the program if you need the source code, reply this mail and i send the source code. Is in Visual Basic.
