SYMPTOMS
When you close a workbook in Microsoft Excel for Windows, the program may stop responding, or you may receive the following error message:

This program has performed an illegal operation and will be shut down.

If the problem persists, contact the program vendor.

If you click Details, you receive an error message similar to the following:

EXCEL caused an invalid page fault in module EXCEL.EXE at 0137:3013a71b.

In Microsoft Excel 98 Macintosh Edition, the program may stop responding, or it may shut down unexpectedly without any error message.



CAUSE
This problem may occur when the following conditions are true:

  The workbook contains a BeforeClose macro, a macro that runs automatically when you close the workbook.

Example: Private Sub Workbook_BeforeClose(Cancel As Boolean) '  End Sub -and-

  The BeforeClose macro contains code that deletes a worksheet in the workbook.

Example: Worksheets("Sheet2").Delete -and-

 When you close the workbook, the active worksheet (Sheet2, in this example) is deleted by the BeforeClose macro.



WORKAROUND
Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. To prevent this problem from occurring, modify your BeforeClose macro so it does not attempt to delete the active worksheet, as demonstrated by the following sample macro: Private Sub Workbook_BeforeClose(Cancel As Boolean)

' If Sheet2, the sheet you want to delete, is the active ' worksheet, then... If ActiveSheet.Name = "Sheet2" Then

' ...activate a different worksheet. Worksheets("Sheet1").Activate

End If

' It is now safe to delete Sheet2. Worksheets("Sheet2").Delete

End Sub



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