I'm trying to read data from the LPT port.Thae number that I get I'll display in a text box.
the reading from the LPT I have done.
My problem is: the number in the LPT maybe changed in each time.
I want to read from the LPT by timer.the external device will write to the LPT each time, but I will read the number let's say every 0.5 sec.
How I can read by a loop and a timer. first I tried with endless loop,but the computer entered to freezing.
please help me...
