Remarks
The ItemRemoved event applies to the References collection. It isn't associated with a control, form, or report, as are most other events. Therefore, in order to create a procedure definition for the ItemRemoved event procedure, you must use a special syntax.
The ItemRemoved event can run only an event procedure when it occurs, it cannot run a macro.
This event occurs only when you remove a reference from code. It doesn't occur when you remove a reference from the References dialog box, available by clicking References on the Tools menu when the Module window is the active window.
Example
The following example includes event procedures for the ItemAdded and ItemRemoved events. To try this example, first create a new class module by clicking Class Module on the Insert menu. Paste the following code into the class module and save the module as RefEvents:
' Declare object variable to represent References collection.
Public WithEvents evtReferences As References
' When instance of class is created, initialize evtReferences
' variable.
Private Sub Class_Initialize()
Set evtReferences = Application.References
End Sub
' When instance is removed, set evtReferences to Nothing.
Private Sub Class_Terminate()
Set evtReferences = Nothing
End Sub
' Display message when reference is added.
Private Sub evtReferences_ItemAdded(ByVal Reference As _
Access.Reference)
MsgBox "Reference to " & Reference.Name & " added."
End Sub
' Display message when reference is removed.
Private Sub evtReferences_ItemRemoved(ByVal Reference As _
Access.Reference)
MsgBox "Reference to " & Reference.Name & " removed."
End Sub
The next Function procedure removes a specified reference. When a reference is removed, the ItemRemoved event procedure defined in the RefEvents class runs.
For example, to remove a reference to the calendar control, you could pass the string "MSACAL", which is the name of the Reference object that represents the calendar control.
Function RemoveReference(strRefName As String) As Boolean
Dim ref As Reference
On Error GoTo Error_RemoveReference
' Return object representing existing reference.
Set ref = objRefEvents.evtReferences(strRefName)
' Remove reference from collection.
objRefEvents.evtReferences.Remove ref
RemoveReference = True
Exit_RemoveReference:
Exit Function
Error_RemoveReference:
MsgBox Err & ": " & Err.Description
RemoveReference = False
Resume Exit_RemoveReference
End Function
