There are application events that excel monitors that you can hook into.

Saved from a previous post:

Put this in the personal.xls project's ThisWorkbook module:

Option Explicit
Public WithEvents xlApp As Excel.Application
Private Sub Workbook_Open()
Set xlApp = Application
End Sub
Private Sub Workbook_Close()
Set xlApp = Nothing
End Sub
Private Sub xlApp_WorkbookOpen(ByVal Wb As Workbook)

'msgbox "Welcome..."

'this autofit columns if the opening workbook was text
Select Case LCase(Right(Wb.Name, 4))
Case Is = ".txt", ".prn", ".csv"
Wb.Worksheets(1).UsedRange.Columns.AutoFit
End Select
End Sub

Save your personal.xls.
Close excel and reopen it. Your personal.xls workbook show open and set up this
application event.

Is there a way of doing it. I have setup this macro in personal.xlsb
file, but it does not get applied when I create a new workbook or open
an existing workbook. It seems to apply only to personal.xlsb file.


Thanks.
