Determining whether an object is a member of a collection in VBA

Question

How do I determine whether an object is a member of a collection in VBA?

Specifically, I need to find out whether a table definition is a member of the TableDe

Answer 1

It requires some additional adjustments in case the items in the collection are not Objects, but Arrays. Other than that it worked fine for me.

Public Function CheckExists(vntIndexKey As Variant) As Boolean
    On Error Resume Next
    Dim cObj As Object

    ' just get the object
    Set cObj = mCol(vntIndexKey)

    ' here's the key! Trap the Error Code
    ' when the error code is 5 then the Object is Not Exists
    CheckExists = (Err <> 5)

    ' just to clear the error
    If Err <> 0 Then Call Err.Clear
    Set cObj = Nothing
End Function
