How to evaluate Expression??

[jonni]

Is it possible to change the expression in “Expression Node” in run-time?

For example: User enters the expression as a string. I need to evaluate it and give the result.

Is it possible to do that?
Any ideas how to sole this problem??

The expression in a formula node cannot be changed at run-time. Instead, use Eval Formula Node (Analyze>Mathematics>Formula palette) or the Advanced Formula Parsing functions on the sub-palette under there. These functions are not in the LabVIEW base package.

Many thanks.... It is exactly what I was looking for.
