Hi, I've got a Method that gets a IDictionary as a parameter. Now I want to provide a method that retrieves the value from this dictionary, but it should be case-invariant.

In my project I have functionality that is being used as a web application and as a console application (to be started from the task scheduler). To do that I put the common code in a DLL that is being used by both the web application and the console application. This works fine. However, the console and web applications now have an App....
I need to convert Word binary documents (version 97 up to 2003) into HTML documents programatically. I have googled for 3rd party libraries but most results are junk built on top of System.IO.Package which, ofcourse, are useless for other word documents except Word 2007 - Office Open XML. Do you know a good tool / library for .NET to pr...
I don't want a discussion about when to and not to throw exceptions. I wish to resolve a simple issue. 99% of the time the argument for not throwing exceptions revolves around them being slow while the other side claims (with benchmark test) that the speed is not the issue. I've read numerous blogs, articles, and posts pertaining one sid...

Just how much slower are events? I have written a streaming XML parser (that can handle open-ended and incomplete documents) and by tearing out the events and using an interface instead I got a significant speed boost. Does any one else have any war stories? (Let's not open the GC can of worms here, we all know it's broken :)) ...
I have a process that reads an XML file. It uses the XMLTextReader class to do this as it is supposed to be a fast, forward only XML parser/reader. Works just great with a 1 megabyte test file but comes to a complete halt when working on a 12 meg file in the live system. Are there any solutions to this other than writing my own XML rea...

When using tooltips to show a detailed description of a TreeNode, the tooltip is drawn on top of the node, as if it was completing the node's text.
