SYMPTOMS
When you attempt to use a customized command button in Microsoft Visio, you may receive the following error message:

Run-time error '424'

Object required.



CAUSE
This behavior can occur if the references to the button are no longer valid because the menu context has been switched to another document.

To resolve this issue, re-establish the reference to the button before each use. To do this, use the following macro: Public Sub DoTest

Dim cb As Office.CommandBar On Error Resume Next Set cb = Application.CommandBars(&quot;Context Switch Test&quot;) cb.Delete Set cb = Nothing On Error GoTo 0

Set cb = Application.CommandBars.Add(&quot;Context Switch Test&quot;) cb.Visible = True

Dim cbc As Office.CommandBarControl Set cbc = cb.Controls.Add(msoControlButton) cbc.Tag = &quot;xxx&quot; cbc.Caption = &quot;Hi There&quot;

Application.CommandBars(&quot;Context Switch Test&quot;).Controls(1).Tag = &quot;xxx&quot; MsgBox (Application.CommandBars(&quot;Context Switch Test&quot;).Controls(1).Tag) MsgBox cbc.Caption

End Sub
