You are creating a Windows Forms application by using the .NET Framework 3.5.
You write the following code segment to bind a list of categories to a drop-down list. (Line numbers are included for reference only.)

01 OleDbConnection cnnNorthwind = new OleDbConnection(connectionString);
02 OleDbCommand cmdCategory = new OleDbCommand( "SELECT CategoryID, CategoryName FROM Categories ORDER BY CategoryName", cnnNorthwind);
03 OleDbDataAdapter daCategory = new OleDbDataAdapter(cmdCategory);
04 DataSet dsCategory = new DataSet();
05 daCategory.Fill(dsCategory);
