We now have the ability to set the page title and breadcrumb trail for all pages in our web application, so we must update the AccountController class we created in 3 to use these features. First, we want all action handlers in this controller to have a base breadcrumb trail of Home: Account , with additional steps depending on the action. To add the Account breadcrumb step automatically, we will define the init() method in this class, which calls the Breadcrumbs::addStep() method. We must also call parent::init(), because the init() method in CustomControllerAction sets up other important data. In fact, this parent method instantiates Breadcrumbs, so it must be called before adding the breadcrumbs step. By automatically adding the Account step for all actions in this controller, we are effectively naming the index action for this controller Account. This means that in the indexAction() function we don t need to set a title, as Breadcrumbs::getTitle() will work this out for us automatically. Listing 6-5 shows the changes we must make to the AccountController class to set up the trail for the register and registercomplete actions. No change is required for the index action. Note that we also set the base URL for the controller in the init() method and change the redirect URL upon successful registration. Listing 6-5. Defining the Page Titles and Trails for the Index and Registration Actions (AccountController.php) < php

PDF Viewer ASP . Net : Embed PDF file on Web Page in ASP . Net ...
19 Sep 2018 ... In this article I will explain with an example, how to implement PDF Viewer in ASP . Net by embedding PDF file on Web Page using C# and VB.

When a DBUtil object is created, the constructor automatically retrieves the connection string from the web.config file, using the technique described in 5. However, it s important to note that this is the web.config file of the web application (as the component doesn t have a configuration file). This is a good design, because it allows a website to use the database component with any database server. However, if the client web application doesn t have the appropriate configuration setting, the database component won t work. The code includes methods for retrieving data (those methods that start with Get) and methods for updating data (those methods that start with Add). This class includes an overloaded method named GetItems(). This means the client can call GetItems() with no parameters to return the full list or with a parameter indicating the appropriate category. ( 2 provides an introduction to overloaded methods.) Each method that accesses the database opens and closes the connection. This is a far better approach than trying to hold a connection open over the lifetime of the class, which is sure to result in performance degradation in multiuser scenarios.

You should already be familiar with the try..catch..finally syntax for handling errors, so you ll now see how to use this syntax to handle any errors that may occur within a page. If an error occurs, you ll write the error to a log file and close the open database connection. 1. Open Select.aspx from the root of the 04 Web site and switch to the Source view of the page. 2. Add the following Import statement to the top of the page after the existing Import statements: <%@ Import Namespace="System.IO" %> 3. Change the Page_Load event as follows (the changed lines of code are shown in bold, and note that the name of the table is deliberately incorrect, with an s at the end): protected void Page_Load(object sender, EventArgs e) { if (Page.IsPostBack == false) { // create the connection SqlConnection myConnection = new SqlConnection(); try { // configure the connection string strConnectionString = ConfigurationManager. ConnectionStrings["SqlConnectionString"].ConnectionString; myConnection.ConnectionString = strConnectionString;

because ADO.NET uses connection pooling to keep a small set of open connections ready to use. As long as you don t change the connection string, every time you call SqlConnection.Open() you receive one of these already-open connections, thereby avoiding the overhead of setting up a new connection.

The code uses its own private FillDataSet() function to make the code more concise. This isn t made available to clients. Instead, the GetItems() and GetCategories() methods use the FillDataSet() function.

// create the command string strCommandText = "SELECT ManufacturerID, ManufacturerName FROM Manufacturers ORDER BY ManufacturerName"; SqlCommand myCommand = new SqlCommand(strCommandText, myConnection); // open the database connection myConnection.Open(); // show the data DropDownList1.DataSource = myCommand.ExecuteReader(); DropDownList1.DataTextField = "ManufacturerName"; DropDownList1.DataValueField = "ManufacturerID"; DropDownList1.DataBind(); // force the first data bind DropDownList1_SelectedIndexChanged(null, null); } catch (Exception ex) { // write the error to file StreamWriter sw = File.AppendText(Server.MapPath("~/error.log")); sw.WriteLine(ex.Message); sw.Close(); // now rethrow the error throw (ex); } finally { // close the database connection myConnection.Close(); } } } 4. Execute the page. You should immediately be presented with the error shown in Figure 4-9. 5. In Windows Explorer, navigate to the C:\BAND\04 folder, and you ll see that a file called error.log has been created. Open that file. You ll see the error has been logged, as shown in Figure 4-10.
