Questioncontrol 5 appliances using pc's parallel port[vb.net 2010] PinmemberLord Christian15-Jan-13 20:10 
AnswerRe: control 5 appliances using pc's parallel port[vb.net 2010] PinmemberBernhard Hiller15-Jan-13 20:42 
There is an important and great technology: it's called debugging.
Set a break point somewhere in your code, e.g at Private Sub btn_app1_Click(...) and then run the code step by step. Thus you will detect the line of code where the exception is thrown.
I guess it happens at Private Sub io(...). Either axHwinterface1 is Nothing, or InPort(888) returns Nothing, then the next line fails.
Debugging will tell you the exact reason.
