Looking for experiences working with Qt
I had an idea for a plug-in for my favorite program runner Launchy, however after downloading the source code I found that it makes heavy use of the Qt library.

I would like to offer a database connection prompt to the user. I can build my own, but it would be nice if I can use something that somebody else has already built (maybe something built into Windows or a free library available on the Internet).

What are the disadvantages of Typed DataSets
I come from a world that favors building your own rather than rely on libraries and frameworks built by others. After escaping this world I have found the joy, and ease, of using such tools as Typed DataSets within Visual Studio. So besides the loss of flexibility what else do you lose?

Centralizing/controlling arbitrary builds of .NET projects and solutions.
Over the years I have created and tweaked a set of NAnt scripts to perform complete project builds. The main script takes a single application end point (a web application project for example) and does a complete, from source control, build of it.

Locate and add project reference for .Net assembly containing a given type?
I'm working with a large (270+ project) VS.Net solution. Yes, I know this is pushing the friendship with VS but it's inherited and blah blah. Anyway, to speed up the solution load and compile time I've removed all projects that I'm not currently working on... which in turn has removed those project references from the projects I want t...

How should I handle a situation where I need to store several unrelated types but provide specific types on demand?
I'm working on an editor for files that are used by an important internal testing tool we use. The tool itself is large, complicated, and refactoring or rewriting would take more resources than we are able to devote to it for the forseeable future, so my hands are tied when it comes to large modifications.
