CLACULATOR BOTTON INTERFACE

[tzviel]

I want to use a front panel with number bottons looking like the windows calculator.

I have made this front panel with the bottons, but it doesn't work right.Instead of the numbers to add from left to right,every new number that I press erases the last one so I am left only with a single digit number.

I am sure this is a common feature in many VI's.

Does anybody have an example how to do this ?

Thanks

Hi tzviel,

If you're using a numeric indicator rather than a string, the trick is to shift the value displayed (x10) and add the value of the button pressed.

I hope the attached VI is useful.

I would recommend starting with the Formula Express VI. There are also other examples that use a calculator interface.

Hope that this helps,
Bob

Thank you for replaying.

SandmanUK, do you have this example in LV 7.0?

It works pefectly !

I just need to use a decimal point also -I think I can make it by myself.
