This posting is an overview document that provides examples of sending SMTP e-mail from .NET 1.1 and .NET 2.0. It covers the differences between each of the .NET versions as well as the methods needed to send SMTP messages using an authenticated SMTP server. Please see the full posting for detailed information

This follow-up post discusses the process to change a user account to a "host" account via SQL. This is a follow-up from my previous blog regarding creating a DNN Host account via SQL.

This posting provides a guide on how to create a new host account within DotNetNuke from your SQL Database. This is very helpful if you ever get locked out of your host account for any reason or for all of the new DotNetNuke users that have been having installation problems with the host and admin accounts. NOTE: This is provided for your use at your own risk!

I have been answering a large number of questions regarding upgrading from DotNetNuke 4.3.5 to 4.4.1 and have created this document to outline the process to complete the upgrade. Please note that I am not responsible for any data loss or corruption that might result from an unsuccessful upgrade of DotNetNuke. Also, even though this tutorial is guided towards users of 4.3.5 this should work for any 4.x version to upgrade to 4.4.1, the upgrade process for 3.x users is NOT the same.

At one time or another I think everyone has been locked out of a system and not been able to get back in. This can be especially troubling if you happen to be locked out of your administrator account. I have seen many people asking how to reset passwords for the host and admin accounts with DotNetNuke so I thought I would write up some simple instructions on how to change a password via the database for any ASP.NET 2.0 website.

One configuration setting that seems to be overlooked frequently with ASP.NET 2.0’s membership provider is the applicationName setting. This setting is very important if you ever want to move your application from one server to another or if you want to share users between multiple ASP.NET applications.

As I mentioned on my homepage I have upgraded this site to DotNetNuke 4.4.1. Overall this was a very smooth process as the actual upgrade went off without ANY problems!  For those of you not aware, when you are upgrading a DNN site you can place an app_offline.htm file in the root of your DNN Location and it will take your application offline.  This is a VERY important feature for those of us with slow upload speeds to our web hosts!!

This is the second part of my Regular Expression overview. In the first article I discussed the basics of creating Regular Expressions and provided a link to test expression patterns using the .NET Framework RegEx classes.  In this article I will discuss the various actions that can be taken to match values in a string using regular expressions.  I will also discuss how you can implement a SQL CLR UDF to allow regular expression validation from your database to provide a strong level of input validation at the database level.

I have created this two part article series to provide a quick and practical introduction to using regular expressions. Regular expressions can be used for many things; however, they are typically used for input validation or to perform advanced searches on text in supporting applications. This first article will explain how to create a regular expression pattern; the expression defines what is considered a match. The second article will provide details on how to implement regular expressions in .NET applications.
