Hi All,

I just wanna ask one simply question..
Is there anyone know how to calculate the output value from a string like
that??

Dim strFormula As String = "20+30+(100+20+30)*0.1"
Dim douOutput As Double

douOutput = Function(strFormula)

what can i do to calculate the dynamic formula string and put it into the
variable "douOutput" ??

Thanks All,

Hi,

There is some VB6 code that can be ported to .NET on www.softcircuits.com.
