You can use the script control for that. Although it doesn't seem to work with variable assignments as in your example. Something like this works fine:

Dim oSC As ScriptControl
Dim iVal As Integer
Set oSC = New ScriptControl
oSC.Language = "VBScript"

Dim toexe As String
toexe = "4*5"
iVal = oSC.Eval(toexe)

MsgBox iVal, vbOKOnly, "Value of iVal"

The script control also has an ExecuteStatement method.
