Parallel Port Problem

[saykhoon]

Hi,

I've encountered a problem when using the parallel port. There are two LEDs blinking one green and the other orange. When the LEDs on my hardware blinks, the GUI will also blink in sync.

When the Green and Orange LED indicator icon are within the while loop the LEDs will blink successfully but when I try to link the Green and Orange indicator outside the while loop, there is no blinking LEDs on my program. Is there any way where I could connect the LEDs indicator outside the while loop? Coz I need to use the Boolean to do some calculations.

Can anyone please kindly help me?

Thanks

I've attached my problem.

Saykhoon,

I am not sure what you are asking. If you need to have the indicator update over and over, you need to have it in a loop. You can do other operations on it inside of the loop as well. Just needing to perform some other Boolean operations on it does not necessarily mean that it cannot be in a loop.

Maybe it would help if we had a little more information about what you are trying to accomplish.

I hope that this helps,
