error when item does not exist in collection ! ?

[fabianus]

When I search an Item in a collection and the item does not exist I get en error instead of "nothing" !?

Don't tell me that that's the way it works - this would be just stupid. Or am I doing any mistake? I do

Dim MyCollection as new collection
MyCollection.add("something","myIndex")
MyCollection.Item("xxx")

This gives an error : The argument 'index' isn't a valid value.

Thank you for any help!

Regards,
Fabian

What I finally did is to create a function that sends back "nothing" instead of throwing an error...

Public Function SearchCollectionItem(ByVal Collection As Collection, ByVal Index As String) As Object
        Try
            Return Collection.Item(Index)
        Catch ex As Exception
            Return Nothing
        End Try
    End Function
