This testing collects the application performance and stability data in different scenarios, and is used for analyzing this data in order to scale the application for better performance.http://www.developerhell.com/out/Storing_User_Profileshttp://www.developerhell.com/out/Storing_User_ProfilesUser Profiles - The profile feature in ASP.NET 2.0 allows you to define and store per-user settings to be used throughout your application. Settings can also be stored in an anonymous profile while users are not logged in, and then migrated to a logged-in user profile at a later time.http://www.developerhell.com/out/Creating_Multiple_Choice_Exam_Application_Part_Ihttp://www.developerhell.com/out/Creating_Multiple_Choice_Exam_Application_Part_IThis is the first part of a multi-part series. In this series we will cover the scenario of creating a multiple choice exam for the user. In the first part I will cover the design of the application. This will include unit tests, domain objects and NHibernate mapping fileshttp://www.developerhell.com/out/Globalization_and_Localizationhttp://www.developerhell.com/out/Globalization_and_LocalizationExplains how to make international applications customizable to users belonging to different nations, cultures, or regions.http://www.developerhell.com/out/Building_a_Gmail_Style_File_Uploading_System_using_ASP_NET_2_0http://www.developerhell.com/out/Building_a_Gmail_Style_File_Uploading_System_using_ASP_NET_2_0This article examines how to upload files to a web server using ASP.NET 2.0 with a different approach. With a click of a hyperlink you can show the "Choose File" dialog box and immediately once the user clicks the OK button from the File Choose dialog box, a file can be uploaded to the server.http://www.developerhell.com/out/Creating_a_Data_Access_Layerhttp://www.developerhell.com/out/Creating_a_Data_Access_LayerIn this tutorial we'll start from the very beginning and create the Data Access Layer (DAL), using typed DataSets, to access the information in a database.http://www.developerhell.com/out/Read_Asp_net_Request_Param_and_Session_dynamically_into_propertieshttp://www.developerhell.com/out/Read_Asp_net_Request_Param_and_Session_dynamically_into_propertiesArticle shows how you can use Attributes and Reflection to dynamically populate property with value from param, session or context without writing any addition code. I have used this technique in past and I hope you will also find it useful.http://www.developerhell.com/out/Data_Visualization_Using_ASP_NET_2_0http://www.developerhell.com/out/Data_Visualization_Using_ASP_NET_2_0Explains how to analyse and graphically visualise numeric data from dataset (iris).http://www.developerhell.com/out/An_Architectural_View_of_the_ASP_NET_MVC_Frameworkhttp://www.developerhell.com/out/An_Architectural_View_of_the_ASP_NET_MVC_FrameworkAt DevConnections Fall and TechEd Europe, Microsoft recently unveiled the ASP.NET MVC Framework. MVC stands for Model-View-Controller and is one of the most popular design patterns for decoupling data access and business logic from data presentation and user interaction. At the time of this writing, the framework is not available yet, not even as a CTP. However, the first CTP is expected to ship in just a few weeks.http://www.developerhell.com/out/Delegates_and_Events_in_Chttp://www.developerhell.com/out/Delegates_and_Events_in_CThis C# tutorial will teach you how to create delegates and events in C# using a practical example of creating two applications, a client and a multi-threaded server. You will learn how to fire your own custom event from a class and handle it in a different class.http://www.developerhell.com/out/An_Introduction_to_AJAX_and_Atlas_with_ASP_NET_2_0http://www.developerhell.com/out/An_Introduction_to_AJAX_and_Atlas_with_ASP_NET_2_0Traditionally, web applications have left a lot to be desired from a user experience standpoint, due primarily to the "request/response" lifecycle. Any interaction with a page typically requires a postback to the web server (a "request"), which then performs any server-side tasks needed and returns the updated page's markup (the "response"). Outside of intranet-based applications, such behavior adds a bit of a lag when interacting with a page. One approach to improving the end user's experience is to use AJAX. AJAX-enabled pages provide a slick, responsive user experience, making web-based applications function more like desktop-based ones.http://www.developerhell.com/out/Recordset_Paging_with_ADO_2_0http://www.developerhell.com/out/Recordset_Paging_with_ADO_2_0Recordset paging is the process of breaking up a recordset into multiple "pages" of information for display. You've probably noticed that most well designed sites implement this feature, allowing you to navigate through a recordset to view a certain number of records at a time.http://www.developerhell.com/out/ASP_NET_2_0_Cachinghttp://www.developerhell.com/out/ASP_NET_2_0_CachingProbably one of the coolest features with ASP.NET is caching, ASP.NET 2.0 has new caching features that I will explore in this article.
