The following example demonstrates how to disable events in an Automation session that controls Excel.

Creating the Excel Macro

To create the macro, follow these steps:

1. Start Microsoft Excel, close all open workbooks, and then open a new workbook.
2. Start the Visual Basic Editor (ALT+F11).
3. On the Insert menu, click Module. In the new module, enter the following code:

   Sub Disable_Events()
      Application.EnableEvents = False
   End Sub
   					

4. In the Project Explorer, double-click ThisWorkbook.
   
   This step displays the code module for the workbook.
5. Enter the following code for the SheetDeactivate event of the workbook:

   Private Sub Workbook_SheetDeactivate(ByVal Sh As Object)
      MsgBox Sh.Name
   End Sub
   					

6. Quit the Visual Basic Editor and return to Microsoft Excel.
7. Select the sheet tab for any sheet other than the active sheet.
   
   A message box displays the name of the sheet that was deactivated.
8. Close and save this workbook as Test.xls on the root directory of drive C.
9. Quit Microsoft Excel.

Creating the Automation Macro

To create this macro, follow these steps:

1. Start Microsoft Word 2000, close all open documents, and then open a new document.
2. Start the Visual Basic Editor.
3. Insert a new module in the project and enter the following code in the module:

   Sub Automation_Example()
   
   Dim xlobj As Object
   Set xlobj = CreateObject("excel.application")
   
      xlobj.Visible = True
      xlobj.EnableEvents = False
      xlobj.Workbooks.Open FileName:="c:\Test.xls"
      'xlobj.Run "Disable_Events"
   
   Set xlobj = Nothing
   
   End Sub
   					

4. Run the Automation_Example macro.
   
   Excel is started and the Test.xls workbook is opened.
5. Select any sheet tab other than the active sheet.
   
   The message box is displayed because events were not disabled by EnableEvents property.
6. Quit Excel.
7. Change the Automation_Example macro to the following:

   Sub Automation_Example()
   
   Dim xlobj As Object
   Set xlobj = CreateObject("excel.application")
   
      xlobj.Visible = True
      'xlobj.EnableEvents = False
      xlobj.Workbooks.Open FileName:="c:\Test.xls"
      xlobj.Run "Disable_Events"
   
   Set xlobj = Nothing
   
   End Sub
   					

8. Run the Automation_Example macro.
9. Select any sheet tab other than the active sheet.
   
   The message box is not displayed because events were disabled by the Disable_Events macro in Test.xls.

NOTE: If the Test.xls workbook had contained a Workbook_Open event, it would not have been disabled because the Disable_Events macro in the workbook would have run after the workbook was opened. A workaround to this scenario is to use an Auto_Open macro in the workbook instead of a Workbook_Open event macro. Because Auto_Open macros are not automatically run when a workbook is opened by running a procedure, the macro does not run in this scenario.
