This happens transparently and automatically, provided you always use the same connection string (even a minor difference such as the order of settings will prevent a connection from being reused) To ensure that the connection string is the same, centralize it in the webconfig file Use data binding: The fastest way to get information out of a database and into a page is to use a DataReader or DataSet and bind it directly to a data control This approach may involve a little more work with custom templates, but it s better than moving through the rows manually and writing to the page yourself Use caching: If a certain set of data is frequently requested and changes infrequently, it s an ideal candidate for caching. c# barcode 128 generator Code 128 Barcode Generator for Microsoft Visual C# .NET

Inline binding to values stored in a DataSet works in much the same way as the previous example with a DataReader. The main difference is that the binding expression is slightly different to accommodate the syntax used to identify tables, rows, and columns inside a DataSet. To see it in action, you ll adapt the previous example to do the same job using a DataSet instead of a DataReader. 1. In Visual Web Developer open Inline_DataReader.aspx and resave it as Inline_DataSet. aspx. Change the <title> tag of the page to be Inline Binding to a DataSet. 2. Add the System.Data Import statement to the top of the page: <%@ Page Language="C#" %> <%@ Import Namespace="System.Data" %> <%@ Import Namespace="System.Data.SqlClient" %> 3. Switch to the Source view. Rather than a DataReader, you need to alter Page_Load to use a DataSet.

Caution Yes, it s just that simple to manufacture an Add to Cart link! The drawback of this simplicity is that it can be potentially used against you. After PayPal confirms the payment, you can ship the products to your customer. On each payment, you need to carefully check that the product prices correspond to the correct amounts, because it s very easy for anyone to add a fake product to the shopping cart, or an existing product with a modified price. This can be done so simply by fabricating one of those PayPal Add to Cart links and navigating to it. You can read a detailed article about this problem at http://www.alphabetware.com/ pptamper.asp. With caching, the information will be read from the database and loaded into temporary memory the first time a client requests it, and it will be made directly available to future requests without any database access required Output caching and data caching are discussed in detail throughout the second half of this chapter.. Session state was the single greatest restriction on performance in traditional ASP development. Although ASP .NET introduces some features that make session state more scalable, it still needs to be used carefully. code 128 checksum c# Make a code128 barcode with C# and iTextSharp - JPHellemons

DataSet myDataSet = new DataSet(); void Page_Load(object sender, EventArgs e) { // set up connection string and SQL query string ConnectionString = ConfigurationManager. ConnectionStrings["SqlConnectionString"].ConnectionString; string CommandText = "SELECT ManufacturerName, ManufacturerCountry, ManufacturerEmail, ManufacturerWebsite FROM Manufacturer"; // create SqlConnection and SqlCommand objects SqlConnection myConnection = new SqlConnection(ConnectionString); SqlCommand myCommand = new SqlCommand(CommandText, myConnection); // create a new DataAdapter SqlDataAdapter myAdapter = new SqlDataAdapter(); myAdapter.SelectCommand = myCommand; // use try finally clauses when the connection is open. try { // open the database connection myConnection.Open(); // use the DataAdapter to fill the DataSet myAdapter.Fill(myDataSet, "Manufacturer"); } finally { // always close the database connection myConnection.Close(); } // bind the data Page.DataBind(); } 4. Now you set which property is bound to which column in the DataTable. Scroll to the bottom of the page to the <body> tag, and change the HTML to the following: <body> <form id="form1" runat="server"> <div> <asp:Label ID="lblName" runat="server"> Name: DataBinder.Eval (myDataSet.Tables["Manufacturer"].Rows[0], "[ManufacturerName]") </asp:Label> You need to make sure this HTML code gets added to each product, so you ll have Add to Cart buttons for each product. To do this, you must modify the ItemTemplate of the DataList control in the ProductsList user control. Then, you ll add the View Cart button somewhere on default.aspx, so it s accessible at any time for the visitor. In BalloonShop, you need to add links such as the one shown previously (Add to Cart links) in the product details pages (Product.aspx), and you need to add the View Cart link on the main web page (so you ll update BalloonShop.master as well). code 128 barcode render c# Packages matching Tags:"Code128" - NuGet Gallery
