parallel port updating with labview

[parallel ports]

I have a project to do that I will need to control using the parallel port. The problem is that I will need to use more than one pin at a time. An example is, when I press button 1, data pin1 and data pin3 will send a signal, and when I press button 2, data pin2 and data pin4 will send s signal and data pin1 and 3 will stop.
I tried doing that but stopped at the programming stage.
I have attached the file I've just did, and I would be most grateful if you kindly pointed me on how to configure this problem.
note: am using win2000 and the parallel port is working fine and i've tried controlling things with it, to make the question more obvious, how could i control the 8 pins and update them as i like. i've read some articles
and answers but didn't understand well since am new to labview

Best regards,

Hi,

find your vi with working parallel port (values should change). You have made a mistake - do not toggle byte/word, the paraport does not support 16bit. In addition I have attached a radio-button selection-vi; this should give an idea, how to select one of xx buttons; maybe the event structure could do the same job for your case. Unfortunately I don't have the time to deliver a complete solution for you....
Hope this helps already. If you have further questions about paraport - mail simply to my .web-address

You will find it by double-clicking on wha@atmel
