To execute an Update, an Insert, or a Delete statement, you need to create a Command object. You can then execute the command with the ExecuteNonQuery() method. This method returns the number of rows that were affected, which allows you to check your assumptions. For example, if you attempt to update or delete a record and are informed that no records were affected, you probably have an error in your Where clause that is preventing any records from being selected. (If, on the other hand, your SQL command has a syntax error or attempts to retrieve information from a nonexistent table, an exception will occur.) asp.net upc-a Barcode UPC-A - CodeProject

Arguments are passed to the controller as keys and values in this array unless it is bypassed in the routes.php configuration file. One important use for arguments is as Cake s way of passing variables to the actions. Notice that because the router has found arguments in the URL string, it does not pass them as variables in the action: http://localhost/blog/posts/view/5/comments:false The previous URL would not result in the second parameter (comments:false) being passed in the action, like the first parameter: function view($id=null) { $displayComments = $this->passedArgs['comments']; This distinction between typical action parameters and passed arguments can make a difference when constructing methods in the controller. The action can still execute without any passed arguments, which can be an important option depending on the specific needs of the action. The record selection code is identical from an ADO.NET perspective, but it now uses the individual text boxes: Protected Sub lstAuthor_SelectedIndexChanged(ByVal sender As Object, _ ByVal e As EventArgs) Handles lstAuthor.SelectedIndexChanged ' Create a Select statement that searches for a record ' matching the specific author ID from the Value property. Dim selectSQL As String selectSQL = "SELECT * FROM Authors " selectSQL &= "WHERE au_id='" & lstAuthor.SelectedItem.Value & "'" ' Define the ADO.NET objects. Dim con As New SqlConnection(connectionString) Dim cmd As New SqlCommand(selectSQL, con) Dim reader As SqlDataReader ' Try to open database and read information. Try con.Open() reader = cmd.ExecuteReader() reader.Read() ' Fill the controls. txtID.Text = reader("au_id").ToString() txtFirstName.Text = reader("au_fname").ToString() txtLastName.Text = reader("au_lname").ToString() txtPhone.Text = reader("phone").ToString() txtAddress.Text = reader("address").ToString() txtCity.Text = reader("city").ToString() txtState.Text = reader("state").ToString() txtZip.Text = reader("zip").ToString() chkContract.Checked = CType(reader("contract"), Boolean) reader.Close() lblResults.Text = "" Catch err As Exception lblResults.Text = "Error getting author. " lblResults.Text &= err.Message Finally con.Close() End Try End Sub To see the full code, refer to the online samples for this chapter. If you play with the example at length, you ll notice that it lacks a few niceties that would be needed in a professional website. For example, when creating a new record, the name of the last selected user is still visible, and the Update and Delete buttons are still active, which can lead to confusion or errors. A more sophisticated user interface could prevent these problems by disabling inapplicable controls (perhaps by grouping them in a Panel control) or by using separate pages. In this case, however, the page is useful as a quick way to test some basic data access code.
