» Workbook events using VBA in Microsoft Excel

VBA macro tip contributed by Erlandsen Data Consulting offering Microsoft Excel Application development, template customization, support and training solutions Events for the Workbook object occurs when the workbook is changed or a sheet in the workbook is changed.
Events in workbooks are activated by default, but can be deactivated by a macro. To display the event
procedures for a workbook you use the Visual Basic editor. Select the desired project in the Project-window
and activate the object ThisWorkbook by doubleclicking it. Any event procedures in the workbook will now be
displayed in the Code-window on the right side of the screen. You can create a new event procedure by selecting
Workbook in the Object dropdown, and then select an event in the Procedure dropdown.
Macros can be attached to the following events in a workbook :

• Activate
• AddinInstall
