Well, I'm not that of a experienced programmer, but I use VB to implement some Operations Reserach algorithms.

How can I do the following?

The user types in a textbox/inputbox some function (like 3*x+5). How can I use this function as an input in the following procedure, let's say:

Function integrate(?) as Double
....
integrate=area
End Function

(for example when you want to numerically integrate this function)

Any help greatly appreciated...

Kind regards,

Gertjan
