how to build a simply calculator?

[kolacmu]

i would to like to build a calculator with the slide to control the operation (+-*/).

May anyone can help me?

Thanks you very much.

A calculator is more than a slide control. You need also something enter numbers, for example.

What have you tried so far?

What specific problems did you encounter that prompted you to ask here?

Is this homework?

Have you started anything? Take a look at this example for some inspiration. Making a slide isn't difficult, just limit the data entry, hide the scale and put some symbols in the right position on the FP and cast the data from an enum (or use the number directly, but an enum aids in self-documentation).

Or just enable "text labels" for the scale. 🙂

I've also did it. If I am not wrong it is an exercise activity from the book "LabVIEW for everyone....". I also did as Altenbach mentioned for the slider part. Attach is the vi. Try to do assignment and activities by yourself it will help you a lot. Don't hesitate to ask but I think first you must try something. This is what I've learned here in forum from these very very interesting, helpful and expert people.

Note that I wasn't implying that we can't provide hints, as long as it's clear the person is making an effort. However, I suspect that the poster is either the same person as edwardty2009 who asked the same exact question, or he has the same exact assignment. Do you really think that they "will do it better next time"? I doubt it. I suspect he'll just come up with a more clever way to ask the question to not make it seem so obvious that it's a homework assignment.

100% agreed.
