I'm new to VB.Net but have been given a task which involves triggering a weighscale and then retriving its weight value in a string.
The PC has an IO card card which I hope to monitor through VB.Net so that when one of the inputs goes true I then want to trigger the Weighscale via an output and then retrieve the weight.
How do I monitor the inputs as a Background Task in VB.Net ie I want to always monitor the IO card and when an input goes high then i want to start reading the weighscale.
I have created a button which triggers the weighscale and retrieves the weight when pressed but i want to be able to trigger the weighscale whenever a certain input goes high.
Do I have to use the timer do achieve it ie check the input card say after every 1sec or is there another clever way
Any Ideas would be appreciated
