New T-SQL Capabilities in SQL Server 2005 - Part 3 of 3

Thu, 26 Apr 2007 12:16:01 GMT

In last month's article, I covered the new APPLY operator, Ranking functions, and the new TRY...CATCH capabilties in T-SQL 2005. This month I'll talk about two of the largest enhancements in the SQL 2005 language - Common Table Expressions (CTEs) and Recursive Queries. Both fo these are part of the SQL-99 standard. CTEs allow developers to more expressively identify a temporary result set (similar to a derived table or temporary view). Recursive Queries allow developers to more easily query hierarchies of data, by permitting developers (in a single SQL statement) to recursively query into a CTE that's also being populated). CTEs and Recursive queries can be a little difficult to initially grasp, so I'm going to show several code examples to demonstrate their value.

The Power of Anonymous Methods in C#

Fri, 27 Apr 2007 17:31:01 GMT

Anonymous methods are a new feature in C# 2.0 that allow you to hook an action directly to an event as opposed to having a separate event handler. For example, when a user clicks a button and you need to pop-up a MessageBox, you could handle it the standard way with a delegate and an event handler, or you could hook the action to perform directly to the Click event using an anonymous method as shown next

Scripting in C#

Wed, 24 Jan 2007 20:31:02 GMT

CS-Script allows you to run C# files as scripts. You can either write straight C# or classless C# files. It also allows you to embed the scripting engine in your own application. It gives you shell integration on Windows so you right click on a .cs file and select "Run as Script". Anyway, very cool stuff, I've used it in a number of my applications.

How Deep are your Defenses?

Fri, 10 Nov 2006 14:31:02 GMT

So, you have built your secured web application. You have enabled ASP.NET's handy authentication and authorization features. But have you done enough? No, not at all. What happens if you forget to deploy the web.config controlling access to the application's administrative folder? Or if an attacker gains access to the box by exploting your database and references your business logic layers? Or if an attacker finds a SQL injection and starts writing directly to the database? In many cases, the short answer is "bad things" oftentimes leading to unemployment. But it need not be so easy for an attacker. There are a number of tactics one can use to extend security beyond the web interface. Like a good army, you must practice defense in depth in order to protect the application.

In this post I will simply show you how to change the mode of the GridView from view to edit.

Simple method to avoid comment spam

Wed, 08 Nov 2006 22:01:01 GMT

It works by adding a small JavaScript to the page that adds a hidden form field when the form is submitted. The value of the hidden field must be the same as a server-side variable to validate. There must also be a property that returns a Boolean value that indicates whether or not the user is human.
