Good coding practices are required to build applications. I suggest you check out: http://www.ssw.com.au/ssw/CodeAuditor/
The Code Auditor is an awesome product from my buddy Adam's company SSW.
I found it to be a really great tool. I ran the Code Auditor against our Access 2 .NET product (built with VS.NET 2003) and the Code Auditor helped me find things and get them done post haste. I think I fixed most things in 2 or 3 hours while watching tv. That’s pretty sweet for an application thats very large and complex. The Code Auditor also works with VS 2005.
