I'm searching for an ORM framework for .NET 2.0 (has to run on Windows 2000, so 3.0/3.5 is out) that is entirely code configured, and does not require XML. I need this to be "hard coded" in the app so that the app can be stand-alone and copied without any support files. I've looked at most of the common ones like nHibernate and the XML...

Can I write a general purpose method to call other methods with a timeout?

I have a problem that is surely familiar to many: I'm making a call (to be specific it is Forest.GetCurrentForest()) which, in some circumstances, will fail to work and throw an exception.

.Net 2.0: Help troubleshooting a System.AccessViolationException. 100% managed code.

RichTextBox links don't do anything

I have a RichTextBox control on a form with some text, some of which are URLs. The DetectUrls property is set to true. The control properly detects my URLs (they're blue, underlined and the cursor changes to a hand when I hover them). However, when I click on them nothing happens (double-click and ctrl+click are similarly ineffective)...

How to SELECT data from SQL Server using .Net 2.0 -- as simple as possible.

Easy question: I have an app that needs to make a half dozen SELECT requests to SQL Server 2005 and write the results to a flat file. That's it. If I could use .Net 3.5, I'd create a LINQ-To-SQL model, write the LINQ expressions and be done in an hour. What is the next best approach given that I can't use .Net 3.0 or 3.5? Are ADO.NE...
