ListArrays - Variable not found in list

[Madame Cholet]

I am sorry, I have posted this in the wrong forum it should be in VB.Net - I can't find a delete post button link anywhere to move it

Hi

I am trying to identify whether a variable I have passed to a listarray exists. If it does I can return the position of the variable using the following function, but how can I return something if it is not found in the list (e.g. variable not found in list so return -1)

PublicFunction WhereAmI_InArray(ByVal TelNum AsString) AsInteger
Dim counter As Integer
Dim aPhone As c_newPhone
For counter = 1 To phoneArray.Count - 1
aPhone = phoneArray(counter)
If aPhone.WhoAmI = TelNum Then
Return counter
End If
Next
End Function

Thanks
