Re: How do I run a program by using a control?

If it's a boolean you just put the VI inside a case and wire the boolean to the case selector... If it's another type of control e.g. a numeric you can either use an event structure and add a value change event case to it where you put the sub-VI or you can store the previous value in a shift

How do I run a program by using a control?

In other words, if I change the value in a control, it executes the vi. TIA, Mark
