IsNumeric Bug

I have implemented my first VB.Net 2005 application and it works fine on my machine but on another machine the IsNumeric function is returning a false when it should be returning a true.

Common.UserLevel = 0

If Not IsNumeric(Common.UserLevel) Then
IsUser = False
End If

Does anyone know of a reason why IsNumeric might work on one machine but not on another?

If IsNumeric is causing an issue, you could always try:

Code:

---

Common.UserLevel = 0

If Not Integer.TryParse(Common.UserLevel, Nothing) Then
    IsUser = False
End If

---

Replace Integer with whatever numeric type that Common.UserLevel is supposed to contain (if it's a floating point, it'd be Double.TryParse(...)).

As to why it's causing an issue, I could not say.
