ACC: How to Find Out If Replica Is the Design Master (138845)

SUMMARY

Microsoft Jet Replication does not have a property that specifies whether a replica is the Design Master of a replica set. However, this article demonstrates how you can use Visual Basic for Applications to determine if a database is the Design Master.

This article assumes that you are familiar with Visual Basic for Applications and with creating Microsoft Access applications using the programming tools provided with Microsoft Access. For more information about Visual Basic for Applications, please refer to your version of the "Building Applications with Microsoft Access" manual.

To determine if a database is the Design Master, follow these steps:

Create a module and type the following line in the Declarations section if it is not already there:
```
Option Explicit
```

Type the following procedure:

      Function IsDesignMaster()

      ' This function determines if the current database is
      ' the Design Master and returns True if the current
      ' database is the Design Master and returns False if
      ' the current database is not the Design Master. The
      ' function returns Null if the database is not a
      ' replicable database.

      Dim db As DATABASE

      Set db = CurrentDb()

        If db.DesignMasterID = db.ReplicaID Then
          If db.ReplicaID = "" Then ' Check to see if db is replicable.
            IsDesignMaster = Null
          Else
            IsDesignMaster = True
          End If
        Else
          IsDesignMaster = False
        End If

      End Function

To test this function, type the following line in the Debug window, and then press ENTER.
? IsDesignMaster()
Note that either Null, True, or False is returned.
