How to determine a text box entr as function???

[aliinal]

Is it possible to use a text box entry as function???

Example...
If the text1.text is 3x^2+4x+3 can i use it as a function?

Yes,
In Project, Add a Reference to Microsoft Script Control 1.0
No need to put script control on a form.

    Dim objScript As New MSScriptControl.ScriptControl
    objScript.language = "Vbscript"
    On error resume next
        MsgBox objScript.Eval("(2*18)^(.5)")
        if Err.Number <> 0 then
            MsgBox err.description
        end if
    On error goto 0
