Hi all,


I am trying to write a program which will send data to the parallel port and light up some LEDs. I dun have problem on the programming part( i think) as i can send data to the parallel port. The problem is, when i send 0(zero) to the port, all LEDs is suppose to be OFF, but the first 3 LEDs still ON.

If you don't understand what am i talking about please visit http://www.codeproject.com/csharp/csppleds.asp

p/s: i dunno where to post this problem, so i post it here. any idea or solution are welcome ^^

Thank you in advanced

Hallie
