choose which boolean value is true

[tetonedge]

I was wondering if someone had a slick way of doing this. I have 4 boolean inputs on the front panel and I want to determine which was clicked to true and then to output the one that was. Thanks

Derek,

The Event structure will do what you want. Set an event for value change on each control. The output from each case can the identifier of the true value.

this is actually occuring in a sub vi, forgot to mention that sorry, how does the event structure handle when being called from a sub vi? Thanks

It should work, as long as the subVI is acting as a dialog box where the user click the boolean button.

okay I will give it a try, thanks

It seems that vi just hangs with the event structure in the subvi. Is there another way? Thanks

Are you passing Boolean values in a main to an event structure in a subVI? That won't work. If you do pass the values to a subVI, in your subVI, all you have to do is use a Build Array and then a Search 1D Array. With the element set to a True Boolean constant, the function will return the index number of the first True it finds in the array.
