• Add the following namespace inclusion to the list of namespaces at the top of the file:Using Microsoft.Practices.EnterpriseLibrary.Data;• Add the code below to the Count menu item handler (inserted code in bold):private void mnuCount_Click(object sender, System.EventArgs e){Database db =DatabaseFactory.CreateDatabase("QuickStarts Instance");int count =(int) db.ExecuteScalar(CommandType.Text, "SELECT COUNT(*) FROMCustomers");MessageBox.Show("There are " + count.ToString() + " customers in thedatabase");}Note: The code above first obtains an Enterprise Library database instance using the data accessconfiguration for the database instance name "QuickStarts Instance" within the configurationfile. The real database connection is not opened at this point.The db.ExecuteScalar command hasmultiple overloads. The selected overload allows specifying some literal SQL to execute, andreturns the result in a similar manner to the SqlCommand .ExecuteScalar method.Thedb.ExecuteScalar method call is responsible for opening and closing the connection to the realdatabase defined in the configuration file, as well as performing any instrumentation required.• Double click on MainForm.cs in the solution explorer to re-open the form in design view.• Double click on the Customers | Load menu item, to add an empty menu click event handler, andinsert the following code:private void mnuLoad_Click(object sender, System.EventArgs e){Database db =DatabaseFactory.CreateDatabase("QuickStarts Instance");DataSet ds =db.ExecuteDataSet(CommandType.Text, "SELECT * From Customers");}dataGrid1.DataSource = ds.Tables[0];Note: The db.ExecuteDataSet method is responsible for opening and closing the connection, aswell as returning a new dataset filled with the results of the SQL Query, which may include multipletables.Task 4 – Configure the application• Add a new Application configuration file (App.config) to the CustomerManagement project.
