ItemTypes' is not accessible in this context because it is 'Privat

[Patrick.O.Ige]

Hi,
I declared ItemTypes as:-
Dim ItemTypes As New ArrayList
Outside the Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArg s) Handles MyBase.Load and have a function that refs it:-
Function SetIndex(ByVal TheItem As String)
Dim i As Integer
For i = 0 To ItemTypes.Count - 1
If TheItem = ItemTypes(i) Then
Return i
End If
Next
End Function
WHat could cause THIS ERROR?
Any ideas!

Hi,

Hi,

Outside the Private Sub Page_Load(ByVal sender As System.Object, ByVal e As

Is it *outside* or *inside*? If it is outside, setting a accessible level of
protected is most appropriate (eg: Protected ItemTypes As New ArrayList).
System.EventArg s) Handles MyBase.Load and have a function that refs it:-
Function SetIndex(ByVal TheItem As String)
Dim i As Integer
For i = 0 To ItemTypes.Count - 1
If TheItem = ItemTypes(i) Then
Return i
End If
Next
End Function
This code will not compile - it will give "Not all code paths return value"
compilation error. Also, note that there is an instance method on the
ArrayList class that does what your function does - it is called IndexOf.
See:

So your function will be reduced to:

Function SetIndex(ByVal TheItem As String)
Return ItemTypes.Index Of(TheItem)
End Function

Another thing - more appropriate name is GetIndex instead of SetIndex
WHat could cause THIS ERROR?
Any ideas!

Hope this helps
