MakeConnection Method [Excel 2003 VBA Language Reference]

Establishes a connection for the specified PivotTable cache.


expression Required. An expression that returns a PivotCache object.


The MakeConnection method can be used after the cache drops a connection and the user wants to re-establish the connection.

Various objects and methods might return a run-time error if the cache is not connected. Use of this method assures a connection before executing other objects or methods.

This method will result in a run-time error if the MaintainConnection property of the specified PivotTable cache has been set to False, the SourceType property of the specified PivotTable cache has not been set to xlExternal, or if the connection is not OLEDB.

Note  Microsoft Excel might drop a connection temporarily in the course of a session (unknown to the VBA programmer), so this method proves useful.


The following example determines if the cache is connected to its source and makes a connection to the source if necessary. This example assumes a PivotTable cache exists on the active worksheet.

Sub UseMakeConnection()

    Dim pvtCache As PivotCache

    Set pvtCache = Application.ActiveWorkbook.PivotCaches.Item(1)

    ' Handle run-time error if external source is not an OLEDB data source.
    On Error GoTo Not_OLEDB

    ' Check connection setting and make connection if necessary.
    If pvtCache.IsConnected = True Then
        MsgBox "The MakeConnection method is not needed."
        MsgBox "A connection has been made."
    End If
    Exit Sub

    MsgBox "The data source is not an OLEDB data source"

End Sub
