When you assign Microsoft Visual Basic code to run for a command button that is displayed in the Visual Basic Editor (not its corresponding Microsoft Office program) by using the OnAction property, the code does not run as expected when you click the command button. However, the same code assigned to a command button in any Office program runs as expected.


This behavior occurs because the Visual Basic Editor CommandBars object does not support the OnAction property. Therefore, the code does not run when you click the command button in the Visual Basic Editor.

To work around this issue, use the CommandBarButton_Click event in a class module instead of the OnAction property. The following sample code illustrates how to create a command button in the Visual Basic Editor and then create a class module to respond to the Click event:
  1. Start Excel.
  2. Click Tools, point to Macro, and then click Visual Basic Editor (or press ALT+F11).
  3. Type or paste the following code in the module:
    Dim oBtns As New Collection
    Function A()
       Dim cb As CommandBar
       Dim oEvt As CBTnEvent
       Set oBtns = Nothing
       Set cb = Application.VBE.CommandBars.Add("TestBar")
       cb.Visible = True
       cb.Position = msoBarTop
       Set oEvt = New CBTnEvent
       Set oEvt.oBtn = cb.Controls.Add(msoControlButton)
       With oEvt.oBtn
          .Style = msoButtonIconAndWrapCaption
          .Caption = "Test"
       End With
       oBtns.Add oEvt
    End Function
  4. On the Visual Basic Editor Insert menu, click Class Module.
  5. In the Properties window, change the class module name to CBTnEvent.
  6. In the new class module, type or paste the following code:
    Public WithEvents oBtn as CommandBarButton
    Private Sub oBtn_click(ByVal ctrl As Office.CommandBarButton, CancelDefault As Boolean)
       MsgBox "Hello"
    End Sub
  7. Click anywhere in the code of function A, and then on the Run menu, click Run Sub/UserForm.
