Is there a way to pass condition of an IF statement as parameter of a function call?

[Guest]

Heloe
I would like to be able to pass a condition of an IF statement as parameter as follow


aStr=†(A=1) and (B=2)â€
if aFunc(“aStrâ€) then
….

End if

and then the fuction process this and return true and false. This is not how i am going to use this just an example of how to send the condition and process it at the called function.

Private sub aFunc (ByVal aCond as string) as Boolean
‘ not suggesting it has to be String

If (aCond) then
Return true
Else
Return false
End if

End sub

How would I do that?
Thanks
Lisa

If the condition doesn't need to be a string, why not type in the
condition directly?

I have function that based on the condition need to perform different things and condition could be many different things I cannot anticipates all the conditions in the function

You need to use the Eval( ) method in order to parse these constructs at
run-time.

Check this out: ms-help://MS.VSCC/MS.MSDNVS/script56/html/vsfctEval.htm

In VB 6 there was a Script Control that implemented the Eval( ) method but
I've not looked for the equivalent control in Dot Net.

Hi Lisa,

This seems to be a fine Eval
