Remove an Object From a Collection When the Index and Key Are Unknown


This can be done by using the is operator. Here is a simple function demonstrating this method:
 
Public Function RemoveObject(Collection As Collection, Object 
As Object)
Dim vTemp As Object
Dim Index As Integer
    Index = 1
    For Each vTemp In Collection
        If vTemp Is Object Then
            Collection.Remove Index
        Else
            Index = Index + 1
        End If
    Next
End Function

If there is only a single instance in the collecion, you can add an exit for:

Public Function RemoveObject(Collection As Collection, Object 
As Object)
Dim vTemp As Object
Dim Index As Integer
    Index = 1
    For Each vTemp In Collection
        If vTemp Is Object Then
            Collection.Remove Index
            Exit For
        Else
            Index = Index + 1
        End If
    Next
End Function
