Trigger an event with a digital input

I have a Digital I/O card. Is there any way to have an Input change trigger an event or is the only solution to use Timer and keep testing the input?

The card is a PCI-DIO24 board, VB6sp5, Win2000

Thanks.

I have not used this card but I am using other cards for digital and analogic inputs and outputs.

Most of them include and ActiveX which allow you to use its events in Vbasic and also you can configure its inputs as level or edge triggered.

If the card does not allows you to get an event from the input value change then you will need to use the timer.

Yep, VB isn't flexible at all when it comes to hardware: you must have an interface to it such ocx or dll.

Are you saying that the I/O card would half to support this?

Thanks again.

What this means is that you a software that is compatable with your hardware. If you don't have it - simply forget about unless you want to contact manufaturer (consider some investment).
