The code then uses the Microsoft.Office.InfoPath.ADOQueryConnection.Command property of the Microsoft.Office.InfoPath.ADOQueryConnection class to display the SQL command text in a message box.
AdoQueryConnection myConnection =
(AdoQueryConnection)(this.DataSources["CityList"].QueryConnection);
MessageBox.Show("SQL command text: " + myConnection.Command);
Dim myConnection As AdoQueryConnection = _
DirectCast(Me.DataSources("CityList").QueryConnection, _
AdoQueryConnection) ;
MessageBox.Show("SQL command text: " & myConnection.Command)
