For my design, I want the user to be able to use start and stop buttons to start and stop a system. Right now, when the user hit the start button, it starts the system by sending a 1 to the dll. I have this in a case structure. The problem is I think by having it in a case structure it continously sends a 1 to the dll. I just want it to send a 1 to the dll once and that is after I press start. Does anybody have any suggestions on how to do this without putting it in a case structure.
Thanks
