The Enterprise Library Data Access Application Block simplifies development tasks that implement common data access functionality. Applications can use this application block in a variety of situations, such as reading data for display, passing data through application layers, and submitting changed data back to the database system. The application block includes support for both stored procedures and in-line SQL. Common housekeeping tasks, such as managing connections and creating and caching parameters, are encapsulated in the application block's methods. In other words, the Data Access Application Block provides access to the most often used features of ADO.NET in simple-to-use classes; this boosts developer productivity.
ADO.NET 2.0 provides classes such as the DbCommand class and the DbConnection class; these classes help to abstract the data provider from any particular database implementation. The Data Access Application Block provides the following benefits: Main Page - ScrewTurn Software. Disable Button On PostBack (ASP.NET) - also works with validation controls - Angus Logan.

In ASP.NET 1.x the primary code model is based on CodeBehind, which uses inheritance and code generation to manage the code that you as the developer work with. In V1 you create a base class into which the VS.NET Editor generates control definitions from the HTML markup – each control gets an instance field on the form and any explicit event hookups are stuck into the InitalizeComponent section of the page. The ASP.NET engine then generates a class from the HTML markup and inherit from your CodeBehind form, in effect providing the functionality you implemented in that class in addition to the generated code.
Some problems with the 1.1 model The concept’s pretty straight forward, but in VS.NET 2003 there are lots of problems with this approach that had to do with the code generation into the CodeBehind class. In many cases control declarations would not make it, or event declarations would get lost. How ASP.NET 2.0 addresses these issues How it works namespace Westwind.WebStore User Controls. Populating Menu Control in ASP.NET 2.0 - using different data sources - The Code Project - Menus & Toolbars.
Download source - 5.39 Kb Introduction ASP.NET 2.0 is coming at us at a very fast pace. I have to admit that ASP.NET 2.0 is very different from ASP.NET 1.x. From now on most of the articles that you will see on this site will target ASP.NET 2.0. What is a Menu Control? The Menu control is used to display menus. Horizontal Menu: Vertical Menu: For making a menu change its orientation you just need to change the Orientation property of the Menu control to Horizontal or Vertical. Now let's see the different approaches to populate a Menu control. Populating the Menu using SiteMapDataSource This is the preferred way of populating the Menu control.
Now let's see how we build our menu using the .sitemap file above. Populating the Menu using the Database Suppose that you have some data in the database tables using which you want to populate the Menu. Let's first look at the GetDataSetForMenu() since its being called from PopulateMenu(). Populating the Menu Control Using an XML File. Designing the Components of an Application or Service.

Structures and Classes. Visual Basic unifies the syntax for structures and classes, with the result that both entities support most of the same features. However, there are also important differences between structures and classes.
Classes have the advantage of being reference types — passing a reference is more efficient than passing a structure variable with all its data. On the other hand, structures do not require allocation of memory on the global heap. Because you cannot inherit from a structure, structures should be used only for objects that do not need to be extended. Use structures when the object you wish to create has a small instance size, and take into account the performance characteristics of classes versus structures. Structures and classes are similar in the following respects: Both are container types, meaning that they contain other types as members. Structures and classes differ in the following particulars: Structures are value types; classes are reference types.
