ACC97: Compilation Error After Converting NWIND.MDB in Access 97

ID: Q160500

The information in this article applies to:

SYMPTOMS

Moderate: Requires basic macro, coding, and interoperability skills.

When you convert the Microsoft Access 2.0 sample database NWIND.MDB to Microsoft Access 97, you receive the following error message:

There were compilation errors during the conversion or enabling of this database.


CAUSE

Microsoft Access 97 supports some new Visual Basic keywords, and you cannot use those keywords as identifiers in your database. The keywords are: AddressOf, Decimal, DefDec, Enum, Event, Friend, Implements, RaiseEvent, WithEvents. When you convert a database from an earlier version of Microsoft Access to Microsoft Access 97, existing identifiers that are the same as new Visual Basic keywords cause a compile error.

In this example, NWIND.MDB uses an identifier called Event in the ShowEvent procedure of the Utility Functions module.


RESOLUTION

After you convert NWIND.MDB to Microsoft Access 97, do the following to fully compile the project:

  1. Start Microsoft Access and open the converted NWIND.MDB.


  2. Open the Utility Functions module in Design view.


  3. On the Debug menu, click Compile Loaded Modules.


  4. Click OK when you receive the compile error message.


  5. Modify the ShowEvent procedure to read as follows: 
    
      Sub ShowEvent (Event_var As String)
      ' Accepts: a text value, the type or name of an object and the name
      ' of an event.
      ' Purpose: displays an event history list in the Event History form.

         If IsNull(Forms![Event History]![History]) Then
            Forms![Event History]![History] = Event_var
         Else
            Forms![Event History]![History] = Event_var & Chr(13) & _
               Chr(10) & Forms![Event History]![History]
         End If
      End Sub


  6. On the Debug menu, click Compile and Save All Modules.
