How to assign an event to multiple objects with excel vba?

Question

I have ten drop down menus on a worksheet each of which should respond the same to the GotFocus() event.

I have written the following code but I get a ru

The below works for me. There were a couple of problem with your code, and comboboxes don't have a GotFocus event, so you'll have to use a different one. The collection needs to be a global in the module, noty part of the class. I couldn't get this to work using the generic "OLEobject" approach (same error you got).

' ### in the class
Public WithEvents inputObj As MSForms.ComboBox

Private Sub inputObj_Change()
    MsgBox "Change!"
End Sub

' ### in a module
Dim tbCollection As Collection

Public Sub InitializePDRInput()
    Dim myObj As OLEObject
    Dim obj As clsPDRInput

    Set tbCollection = New Collection

    For Each myObj In Worksheets("Sheet1").OLEObjects
        If TypeName(myObj.Object) = "ComboBox" Then
            Set obj = New clsPDRInput
            Set obj.inputObj = myObj.Object
            tbCollection.Add obj
        End If
    Next myObj

End Sub
