Use error handling to trap error 2046.
Here's what I use. The code opens/activates the switchboard when the user
closes all other visible forms and reports.
Set the On Close property of all forms except the switchboard to:
=Keep1Open([Form])
and for reports:
=Keep1Open([Report])
Note: it's exactly that: do not substitute the name of the report or add
quotes.

Public Function Keep1Open(objMe As Object)
On Error GoTo Err_Keep1Open
'Purpose: Open the Switchboard if nothing else is visible.
'Argument: The object being closed.
'Return: None.
'Usage: In the OnClose property of forms and reports:

Dim sName As String 'Name of the object being closed.
Dim lngObjType As Long 'acForm or acReport
Dim bFound As Boolean 'Flag not to open the switchboard.
Dim frm As Form 'an open form.
Dim rpt As Report 'an open report.

lngObjType = acForm

For Each frm In Forms

End If
End If

If Not bFound Then
DoCmd.OpenForm "fSwitchboard"

If Err.Number <> 2046& Then 'OpenForm is not available when closing
database.
