ATTENTION: I've decided to put the upgrade on hold due to a compatibility issue of our server environment with the latest CS installer package. CS 2008 now requires SQL Server 2005 as the backend DB but our database server currenlty has SQL Server 2000 installed on it. I'll resume the upgrade once I figure out when Telligent is releasing a patch to the schema compatibility issue. For now, we will continue to use the old version of CS while waiting for the said patch. If you have any questions about this process, please don't hesitate to post them on our forums and I'll answer them as soon as I can. Thanks for your patience and support guys! I'll let you know as soon as this is resolved. - Keith Rull

HashTable and Dictionary Difference

So far, I have been using just two classes of the System.Collections.Generic namespace, List<T> and Dictionary<K,T>. At first I thought that Hashtable and Dictionary<string, T> are of the same fruit, the difference is the eliminated...

I'm working on a GridView and I'm databinding a List<BusinessObject> to it. All is well until I tweaked some code and suddenly, I got this System.Web.HttpException with message A data item was not found in the container. The container must...

Singleton usage

We currently have a Singleton class in our application which in the next phase of development will change to a multi-instance. The problem is every class which makes use of it accesses it directly through the exposed static interface. I believe this is...
