Microsoft has built "blocks" for you to reuse as part of an application.

One of those is called the "Data Access Application Block" that hides some of this complexity.

>I have been playing around with getting data from SQL, and thinking about how I would go about designing a Data Layer Object. I have always worked with stored procedures, so I am very comfortable with setting up parameters. I do need to ask though .. the following code seems to be a lot of work to pull a single value from SQL? Is this code correct or have I over complicated things?
