No, you do not need a reference when you use CreateObject. You are running
this from Excel rather than the VBE? The only time I had a problem was when
I started it from the VBE and switched to Excel while it was running.

Sub SelfClosingMsgBox()
Dim wsh As Object
Set wsh = CreateObject("WScript.Shell")
wsh.Popup "Hello!", 2, "This closes itself in 2 seconds"
End Sub

Some people responsed that it didn't close for them. I didn't have any
problem with it.

Tested in xl97 SR2, windows 98 SE
xl2000, Windows 2000
xl2000, Windows XP Pro (although it seemed to hang around
longer than 2 seconds)

My code includes the following.

Dim Message, Title, Response
Message = "Entry must be numeric."
Title = "Invalid Entry"
Response = MsgBox(Message, Style, Title, Help, Ctxt)

and, in a separate module,

Sub Auto_Open()
' bunch of code
Application.OnTime Now + TimeValue("00:00:30"), "Close_Workbook"
' more code
End Sub
Sub Close_Workbook()
Application.DisplayAlerts = False
ThisWorkbook.Close
End Sub

I want to guard against someone walking away without responding with an
"OK" to the message.
Is there a way I can get the workbook to automatically close while the
MsgBox is still open?

Thanks in advance.
