DataRecordset.DataConnection Property (Visio)
Returns the DataConnection object associated with the DataRecordset object. Read-only.
This Visio object or member is available only to licensed users of Visio Professional 2013.
You can get the connection string associated with a data recordset by first using the DataConnection property to get the DataConnection object associated with the data recordset and then getting the DataConnection.ConnectionString property value.
The DataConnection property returns Nothing for "connectionless" DataRecordset objects—those that are created by using the DataRecordsets.AddFromXML method.
