I want an example source code in Delphi 7 for this:

I want when the program receives a signal to show that an external switch has been closed for example to pin 2 of the parallel port LPT1(actually it's a relay contact so I could feed it a voltage, high, low e.t.c.) to set true the value of check box.

I want to use it in Windows 2000 server and XP.

Thanks in advance!
