The power and flexibility of validation controls are demonstrated using the CustomValidator control to connect to a Web Service that verifies addresses. A shopping cart is then implemented in ASP.NET using the DataGrid, and finally, credit card authorization and billing are performed.
-
.NET Reflection: Dynamically Bind Your Data Layer to Stored Procedures and SQL Commands Using .NET Metadata and Reflection
Atif Aziz - August 2002
One major inconvenience of using SQL stored procedures from code is having to match type information. You have to write long wrapper functions around the procedures just to expose the data types. In the .NET Framework, however, the reflection services of the System.Reflection namespace allow you to query rich metadata that describe data types. This article explains how to use reflection in .NET to end your stored procedure nightmares. The author creates four custom classes, including one that generates a SQLCommand object based on the metadata of a method. Using this library, you'll be on your way to automating the generation of stored procedures.
