XL97: Cannot Stop Macro After Switching to Other ProgramLast reviewed: March 13, 1998Article ID: Q163497 |
The information in this article applies to:
SYMPTOMSWhen you run a Visual Basic for Applications macro in Microsoft Excel 97, the following problems may occur:
CAUSEThis problem may occur when the following conditions are true:
WORKAROUNDTo work around this problem, wait for the macro to finish running. After the macro is finished, Microsoft Excel 97 updates the screen. If you wait for a long time and the macro does not finish running, It may be necessary to end the instance of Microsoft Excel 97 by pressing CTRL+ALT+DEL. Microsoft provides examples of Visual Basic for Applications procedures for illustration only, without warranty either expressed or implied, including, but not limited to the implied warranties of merchantability and/or fitness for a particular purpose. The Visual Basic procedures in this article are provided 'as is' and Microsoft does not guarantee that they can be used in all situations. While Microsoft support engineers can help explain the functionality of a particular macro, they will not modify these examples to provide added functionality, nor will they help you construct macros to meet your specific needs. If you have limited programming experience, you may want to consult one of the Microsoft Solution Providers. Solution Providers offer a wide range of fee-based services, including creating custom macros. For more information about Microsoft Solution Providers, call Microsoft Customer Information Service at (800) 426-9400. Although it is not possible to prevent this problem from ever occurring, you can lessen its affects by adding MsgBox commands to the Visual Basic macro. For example, assume you are running the following Visual Basic macro:
Sub Test() For X = 1 To 4000 ThisWorkbook.Worksheets(1).Cells(1, 1).Value = X Next X For Y = 1 To 4000 ThisWorkbook.Worksheets(1).Cells(1, 2).Value = Y Next Y For Z = 1 To 4000 ThisWorkbook.Worksheets(1).Cells(1, 3).Value = Z Next Z End SubWhen you run this macro, switch to another program, and then switch back to Microsoft Excel 97, you may not be able to halt the macro by pressing ESC. Also, the screen may not be updated properly until the macro is finished. However, you can add message boxes that allow the screen to be updated. For example, type the following subroutine:
Sub Test() For X = 1 To 4000 ThisWorkbook.Worksheets(1).Cells(1, 1).Value = X Next X MsgBox "Stage one complete!" 'new line of code For Y = 1 To 4000 ThisWorkbook.Worksheets(1).Cells(1, 2).Value = Y Next Y MsgBox "Stage two complete!" 'new line of code For Z = 1 To 4000 ThisWorkbook.Worksheets(1).Cells(1, 3).Value = Z Next Z MsgBox "Stage three complete!" 'new line of code End SubWhen each loop is completed, the macro displays a message box. When you click OK, the screen is updated properly, and you can halt the macro by pressing ESC.
STATUSMicrosoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
MORE INFORMATIONThis problem occurs even if the Visual Basic macro contains one of the following lines of code:
Application.EnableCancelKey = xlInterrupt -or- Application.EnableCancelKey = xlErrorHandler |
