How about a few code snips to turn on/off the individual pins of the port. Not where the dll can be fund, not where you "think" it can be found. Just code snips.
I've looked for ths for over 2 years, nada. I know what's on lvr. I know what's on logix4u. I know what is on code project. I need code snipps I can use or try to use in the visual studio.
