Math expression validator, not evaluator??

[Guest]

Hi everyone,
I am developing a WinForms application and I need a Math Expression
validator, not an expression evaluator. So I want to be able to say...

if ((sales - tax) > 20)
THEN (x * y * 0.55)

without knowing at runtime what the values of sales, tax, x and y are. These
values will be filled when this validated rule is fetched from where it has
been stored. Is there any software out there that will do this validation for
me?

Thanks in advance

What is the overall goal ?

AFAIK you can add scripting capabilites to an application. Try :
