    This sample shows how to use DbDataTable. The routine accepts DbTable-compatible object, IDbCommand implementor object, and IDbConnection implementor object as parameters. After SQL query text has been set the data is retrieved from the table.
    public void UseDataTable(DbDataTable myDataTable, DbCommand myCommand, DbConnection myConnection)
    {
      myDataTable.Connection = myConnection;
      myCommand.CommandText = "SELECT * FROM Test.Dept";
      myDataTable.SelectCommand = myCommand;
      try
      {
        myDataTable.Active = true;
        foreach(DataRow myRow in myDataTable.Rows)
        {
          foreach(DataColumn myCol in myDataTable.Columns)
          {
            Console.Write(myRow[myCol]+"\t");
          }
          Console.WriteLine();
        }
      }
      finally
      {
        myDataTable.Active = false;
      }
    }
    Public Sub UseDataTable(ByVal myDataTable As DbDataTable, ByVal myCommand As DbCommand, ByVal myConnection As DbConnection)
      myDataTable.Connection = myConnection
      myCommand.CommandText = "SELECT * FROM Test.Dept"
      myDataTable.SelectCommand = myCommand
      Try
        myDataTable.Active = True
        Dim myRow As DataRow
        Dim myCol As DataColumn
        For Each myRow In myDataTable.Rows
          For Each myCol In myDataTable.Columns
            Console.Write(myRow(myCol) & Chr(9))
          Next myCol
          Console.WriteLine()
        Next myRow
      Finally
        myDataTable.Active = False
      End Try
    End Sub
