Excel/Start macro when workbook is opened


Hi Tom,
Excel 2007 VBA

What's the best way to have a macro start automatically when the workbook is opened?

In the visual basic editor (VBE) look on the left side at the project explorer.  Your workbook should be shown there.  right click on the ThisWorkbook entry for that workbook.  Select view code.  In the left dropdown at the top of the resultant module, select Workbook.  In the Right dropdown, select Open (this may appear as soon as you click workbook).

Private Sub Workbook_Open()

End sub

This is the Open event for the workbook.  It will run whenever the workbook is opened and macros are not disabled.  Put the code in this event or call it from this event.

After you set up the code, make sure you save the workbook.
