XL97: Open Event Macro May Not Activate a Worksheet

ID: Q174319

The information in this article applies to:

Microsoft Excel 97 for Windows

SYMPTOMS

If you have an Open event macro for your workbook and this macro has code to activate a worksheet, the macro will run, but the worksheet may not be activated.

CAUSE

Your Open event macro may not activate a worksheet if both of the following are true:

You have a custom function, either in the workbook with the Open event macro, or another workbook in memory.
```
    -and-
```
Your custom function uses the Volatile method.

To work around this problem, use either of the following methods:

Remove the line of code containing the Volatile method from your custom function.
```
    -or-
```
Use an Auto_Open macro instead of an Open event macro for the workbook.

For example, if your Open event macro is as follows:

   Private Sub Workbook_Open()

      Sheet2.Activate

   End Sub

use the following macro code (on a general module) instead:

   Sub Auto_Open()

      Sheet2.Activate

   End Sub

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.
