XL98: Referenced Workbooks and Add-Ins Are Automatically Opened (181464)

MORE INFORMATION

In Microsoft Excel 98 Macintosh Edition, you can create a reference from one workbook to another workbook or to an add-in by following these steps:

1. Switch to the workbook from which you want to create the reference.
2. On the Tools menu, point to Macro, and then click Visual Basic Editor.
3. On the Tools menu, click References.
4. In the References dialog box, select the check box to the left of the file for which you want to create the reference. If the file is not listed, click Browse, select the file in the Add Reference dialog box, and then click Open.
5. When you are done, click OK.

A workbook that contains a reference to another workbook or to an add-in is a "referencing" workbook. A workbook or add-in that is referred to by another workbook is a "referenced" workbook.

   On Error Resume Next                   ' Prevents the error message.
   Workbooks.Open FileName:="Book2.xls"   ' Opens the workbook or add-in.
   On Error GoTo 0                        ' Restores normal error handling.
				

Errors Closing Referenced Workbooks or Add-Ins

In Microsoft Excel 98 Macintosh Edition, you cannot close a referenced workbook or add-in if the referencing workbook is open. If you attempt to do so, you receive one of the following error messages: For more information about this problem, please see the following article in the Microsoft Knowledge Base:

Errors When Multiple Users Reference the Same Workbook or Add-In

Because Microsoft Excel 98 Macintosh Edition automatically opens referenced workbooks and add-ins, you may experience problems if multiple users reference the same copy of a workbook or an add-in. This problem may occur if you create a reference to a workbook or to an add-in that is stored on a network server, or if you open a workbook that contains this kind of reference.

The first user who creates the reference does not receive an error message. However, all users who subsequently create a reference or open a workbook that contains this kind of reference may receive the following error message: If you click Cancel in the File Reservation dialog box, you may also receive the following error message: If you use a Visual Basic macro to open the referencing workbook, the previous error message may not appear immediately, and the workbook is opened without any problems. When the error message does appear, click Read-Only or Notify.

If multiple users share the same copy of an add-in, you may want to give each user a copy of the add-in, and then ask each user to change the reference to refer to each copy of the add-in. By doing this, you can prevent this problem from occurring.
