I am trying to force closure of an Excel 2003 workbook via VBA behind a user
form rather than with the normal File | Close or X and have tried several
different approaches; none of which solves the problem. When the user form
is hidden, the File | Save and X close options are available and if selected
cause a fatal crash. I want to retain the ability to save and close normally
for program maintenance, but want to present a normal user with a message and
process to exit the program via the user form. I have tried code in
Workbook_BeforeClose, but it seems that the routine gets called twice. It
works as expected the second time through. The code I'm using is:

Private Sub Workbook_BeforeClose(Cancel As Boolean)
'Check to see if frmEntry is loaded
If isFormLoaded(frmEntry) Then
MsgBox "You must close the application via the Exit button on the
Entry form."
'Restore form
frmEntry.Show
End If

End Sub

It calls the function below:

Function isFormLoaded(frmName As Object) As Boolean
Dim intI As Integer

'initialize the return value to false
isFormLoaded = False

'loop through all open forms
For intI = 0 To UserForms.Count - 1
'test to see if the current form has the
'same name as the frmName
If UserForms(intI) Is frmName Then
'return true
isFormLoaded = True
'exit the loop
Exit For
End If
Next
End Function

Any help you can provide with this code or any other options will be
sincerely appreciated.

Thanks...
