Some of the most interesting HTTP handlers don t generate HTML. Instead, they render different types of content, such as images. This approach gives you the flexibility to retrieve or generate your content programmatically, rather than relying on fixed files. For example, you could read the content for a large ZIP file from a database record and use Response.BinaryWrite() to send it to the client. Or, you could get even more ambitious and use your HTTP handler to dynamically create a ZIP archive that combines several smaller files. Either way, to the client who is using your HTTP handler, it seems as though the browser is downloading an ordinary file. But in actuality, the content is being served using ASP.NET code. The following example demonstrates an HTTP handler that deals with image files. This handler doesn t create the image content dynamically (for that trick, refer to 29), but it does use code to perform another important task. Whenever an image is requested, this HTTP handler checks the referrer header of the request. The referrer header provides the host name, which indicates whether the link to the image originates from one of the pages on your site, or whether it stems from a page on someone else s site. If the page that s using the image is on another site, you have a potential problem. Not only is this page stealing your image, it s also creating more work for your web server. That s because every time someone views the third-party site, the image is requested from your server. If the stolen image appears on a popular site, this could generate a significant amount of extra work and reduce the bandwidth you have available to serve your own pages.

generate code39 barcode data in java? - Stack Overflow
According to Wikipedia Code 39 is restricted to 43 characters.In order to generate it's encoding data I've used the following code:

The first step is to add two parameters to the SqlDataSource.UpdateParameters collection. Unfortunately, you can t create these while the update is in progress. Instead, you need to add them to the SqlDataSource tag: <asp:SqlDataSource ID="sourceEmployees" runat="server" ProviderName="System.Data.SqlClient" ConnectionString="<%$ ConnectionStrings:Northwind %>" SelectCommand= "SELECT EmployeeID, FirstName, LastName, TitleOfCourtesy FROM Employees" UpdateCommand="UpdateEmployee" UpdateCommandType="StoredProcedure" OnUpdating="sourceEmployees_Updating" > <UpdateParameters> <asp:Parameter Name="First" Type="String" /> <asp:Parameter Name="Last" Type="String" /> </UpdateParameters> </asp:SqlDataSource> Note that the parameter names don t include the @ symbol when you define them in the SqlDataSource tag. The next step is to react to the SqlDataSource.Updating event, which fires immediately before the update is committed. You can then set the value for the @First and @Last parameters and remove the @FirstName and @LastName parameters from site. Here s the code you need: Protected Sub sourceEmployees_Updating(ByVal sender As Object, ByVal e As SqlDataSourceCommandEventArgs) e.Command.Parameters("@First").Value = e.Command.Parameters("@FirstName").Value e.Command.Parameters("@Last").Value = e.Command.Parameters("@LastName").Value e.Command.Parameters.Remove(e.Command.Parameters("@FirstName")) e.Command.Parameters.Remove(e.Command.Parameters("@LastName")) End Sub This represents a fairly typical scenario in which the no-code data binding won t work. Overall, if you can design your stored procedures and classes to work with the data source controls, you ll avoid writing a great deal of code. On the other hand, if you introduce the data source controls to an existing application with a fixed database schema and database components, it may take a fair bit of extra code to fit these pieces together.

This problem sites that steal bandwidth by linking to resources on your server is known informally as leeching. It s a common headache for popular websites that serve large amounts of non-HTML content (for example, photo-sharing sites such as Flickr). Many websites combat this problem using the same technique as the HTTP handler described previously namely, they refuse to serve the image or they substitute a dummy image if the referrer header indicates a request originates from another site. Here s an HTTP handler that implements this solution in ASP.NET: public class ImageGuardHandler : IHttpHandler { public void ProcessRequest(System.Web.HttpContext context) { HttpResponse response = context.Response; HttpRequest request = context.Request; string imagePath = null; // Check whether the page requesting the image is from your site. if (request.UrlReferrer != null) { // Perform a case-insensitive comparison of the referrer. if (String.Compare(request.Url.Host, request.UrlReferrer.Host, true, CultureInfo.InvariantCulture) == 0) { // The requesting host is correct. // Allow the image to be served (if it exists). imagePath = request.PhysicalPath; if (!File.Exists(imagePath)) { response.Status = "Image not found"; response.StatusCode = 404; return; } } } if (imagePath == null) { // No valid image was allowed. // Return the warning image instead of the requested image. // Rather than hard-code this image, you could // retrieve it from the web.config file // (using the <appSettings> section or a custom // section). imagePath = context.Server.MapPath("~/Images/notAllowed.gif"); } // Set the content type to the appropriate image type. response.ContentType = "image/" + Path.GetExtension(imagePath).ToLower(); // Serve the image. response.WriteFile(imagePath); }

As you ve seen, when you use the SqlDataSource, you can often avoid writing any data access code. However, you also sacrifice a fair bit of flexibility. Here are the most significant disadvantages: Data access logic embedded in the page: To create a SqlDataSource control, you need to hardcode the SQL statements in your web page. This means you can t fine-tune your query without modifying your web page. In an enterprise application, this limitation isn t acceptable, as it s common to revise the queries after the application is deployed in response to profiling, indexes, and expected loads.
