Question

If My.Settings.Sup1 Is Nothing Then
        My.Settings.Sup1 = New Collections.ArrayList
        My.Settings.Sup1.Add(0)' array index can't be negative or less than 0
        My.Settings.Sup1.Add(0)
        My.Settings.Sup1.Add(0)
        My.Settings.Sup1.Add(0)
    End If

why would i even get this exception in the commented line, is there anything wrong with the above code

i tried insert and assigning a value to the current index and still i am getting the exception

Answer 1

I added an User Setting on the Project Properties → Settings Tab of Type System.Collections.ArrayList and it works as expected. Not sure what your problem is your code looks fine, I would double check your Type and make sure it is correct.
