How can a String expression be evaluated? If I have a String Variable
like '2+5>=5' and I whan't to check if it's true how can i do it?

Any ideas?

Luc, Unless I'm wrong the return of those will be a number. What I wan´t is something to return 'true' or 'false', depending if the expression if true or false. Something that checks if a string is part of "Filter"


Function('23234','23*') would return true

Is this possible?

Use Microsoft Script Control.

VariantVal : Variant
Script: Automation 'Microsoft Script Control 1.0'.ScriptControl"

CREATE(Script);
Script.Language := 'VBScript';
VariantVal := Script.Eval('2+5>=5');
