I'm guessing you have something resembling a "comments" table, with a foreign key to itself, pointing to the parent comment of each row. This makes the threaded comments into a tree structure with the thread starter as the tree root.
So we can rephrase the question as "What is the best way to select a tree structure... |
Changing ctrl+tab behavior for moving between document in Visual Studio |

Is it possible to change how **ctrl+tab** and **shift+ctrl+tab** work in Visual Studio? I have disabled the popup navigator window because I only want to switch between items in the tab control. My problem is the inconsistency of what switching to the next and previous document do.

I worked on a project last summer that required some pretty heavy modifications to .NET Remoting.

Issues using MS Access as a front-end to a MySQL database back-end? |

Two users wanted to share the same database, originally written in MS Access, without conflicting with one another over a single MDB file.

I know this doesn't answer your question directly, but it might be worth checking out the [SQL Server 2005 migration tool for Access][1]. I've never used the tool, but it might be worth using with SQL Server 2005 Express Edition to see if there are the same issues as you had with MySQL

Personally, I would store all of these different user classes in a single table. You can then either have a field which stores a 'Type' value, or you can imply what type of person you're dealing with by what fields are filled in. For example, if UserID is NULL, then this record isn't a User.

In the past I've done it exactly as you suggest -- have a Person table for common stuff, then SpecialPerson linked for the derived class.

If I'm reading your question right, I think you're looking for the [InputStream property][1] on the Request object. Keep in mind that this is a firehose stream, so you can't reset it.

Do you actually **need** to do this? If you're using some kind of pseudo factory pattern without a true design need for it, you're only going to make your code harder to understand, maintain and extend.

window.onload on IE waits for the binary information to load also. It isn't a strict definition of "when the DOM is loaded".
