Today’s column has caused quite a stir within the SQL Server community. I’m not a DBA by any stretch of the imagination but there are many DBA’s who hit the panic button as soon as they found out that Microsoft was integrating the CLR into SQL Server 2005. For them, this meant anywhere from T-SQL being replaced to giving the application developers free reign to the database and everything in between. Fortunately, none of this is true. This article will discuss the integration of the CLR in SQL Server 2005 and what that means for both DBA’s and .NET developers alike. Read More..
The purpose of this article is to demonstrate how to create a simple composite server control for ASP.Net 2.0. Just as important, or more importantly, it demonstrates the benefits of creating your own custom server controls. I will demonstrate these points by walking through a simple example scenario where the task is accomplished without the use of a custom control. We will then turn the solution into a custom server control that can be reused throughout our sites and across various other projects where such functionality would be useful. Read More..

Frequently with applications many of the operations they perform are dynamic depending on several factors. Think about a common scenario, sales tax. Tax amounts are based off the place where you live. There are many different tax rates in each country. A good method of implementing dynamic patterns like taxes is needed. The strategy pattern covers this gap for us. Read More..

The Proxy design pattern shows a way to do just in time loading of objects that would consume too much memory to keep around, or takes a lot of time to load. This can be a very useful pattern for many applications. A good example of this pattern is in Microsoft Office. When you open a large Word document that has lots of embedded pictures, Office doesn’t load them all at the time you open the document. As you scroll down, Office will pull the pictures from the disk file and insert them into the document. You can see this by scrolling very fast down the document. It takes a second or so for the document to “catch up” to you and show the visible images. Read More..

This functionality is accomplished with the command pattern. The GOF book says to use a command pattern when: Read More..

The visitor design pattern is very useful in situations where normal polymorphism won’t work because we have fundamentally different objects, with different interfaces, that you want to work on your concrete main object. The pattern is used to give us a way to do these different operations on the object. According to the GOF book, you use the visitor pattern when: Read More..

Dot Net has an interesting and very useful concept called Reflection. Since your compiled programs in Dot Net are compiled to IL and not machine code, it is very easy to query an EXE or DLL for what information it exposes in the form of classes, methods and properties, etc. In this article I will show you how to create a very simple and easy method for ”plug-in” type architectures.
