I need to implement a Diff algorithm in VB.NET to find the changes between two different versions of a piece of text. I've had a scout around the web and have found a couple of different algorithms.
Does anybody here know of a 'best' algorithm that I could implement?
Well I've used the c# version on codeproject and its really good for what I wanted...

You can probably get this translated into VB.net via an online converter if you can't do it yourself...
I like An O(ND) Difference Algorithm and Its Variations by Eugene Myers. I believe it's the algorithm that was used in GNU diff. For a good background see Wikipedia.
This is quite theoretical and you might wish to find source code, but I'm not aware of any in VB.
I don't know for sure if it's the best diff algorithms but you might want to check out those links that talks about SOCT4 and SOCT6

Is there some kind of obvious database should I use for a Bulletin Board if I wanted to code one? I think I know how to code the rest of it, I know the imperative code to handle the logic, but I don't really know much about databases yet. This I can learn of course, I'm just wondering if there is something obvious I should know in the beginning, or an obvious place to start learning, besides sql 101. Also, please don't suggest reading the code of an open source project. I know that option is there. It's hard to decipher code in a language you don't understand really well.
You can check out this place they've got tons of database sample you can use to jumpstart a project http://www.databaseanswers.org/data_models/

I am in need of an outline on teaching VB6/VBA to some co-workers. The material I am pretty confident I can fill in, just need a sense of how to order the class material. Its not going to be hard core programming [nix the VB6 jokes please :) ] but do want to touch the basics. Any free outlines or even entire presentations out there that I can use? I've been looking but nothing concrete so far.
thanks
If you mean VBA say VBA, not VB6. They differ a great deal based on the object models available, and the actual language syntax is a fairly simple thing to pick up.
Just look for some Dummies, O'Reilly, etc. books to use as a teaching guide. Maybe even go with self-study making yourself available for questions and general help, and to prod them along.
Well I went to the public library and found a book called "Visual Basic In Easy Steps". that seems to have a good outline and it covers VB6 and VBA. Straight and simple.

I've been learning PHP OOP for quite a while and I've loved getting to know the language, finding solutions to problems and so forth.
Although, quite often, people keep recommending different frameworks for me to start using. I can imagine using a framework is more efficient, time effective and so forth but It seems to take quite a lot of the fun out of things.
My next challenge is to create a fully functional tutorial website and blog.
My question is, do you use a PHP framework and should I really start using one?
I was also debating whether to use CodeIgniter or CakePHP...

I would like to know if there are any tutorial websites for learning PyObjC apart from the home page of the project itself. I'm enthusiastic about being able to use python to develop native code and be productive without learning how to program in some of the other more traditional compiled languages. Anywhere I could get a screencast or good beginner tuts would be excellent.
You could start with Will Larson's stuff. You could read the Apple docs and do the temperature conversion thingie. You could do what I did and get Hillegass's book and then do the examples using PyObjC. You could read my stuff. I have lots of simple examples, but I'm just an amateur. You don't need to worry about Objective-C yet, but if you stick with it, you probably will.
And you really must learn that case matters.

I am using WIX at the moment, but keep on running into limitations (such as ability to expand properties as the value of another property). Also not sure if I ran into a bug with the FileSearch element, because it is not working as expected (does not find a file that is definitely there). I can go the route of using custom actions built into a dll, but was just wondering if there is a beter way.
I think the best tool (maturity, features, documentation, easy-of-use) is currently AdvancedInstaller. I'm not usually recommending commercial tools but this one is really good value for money.
They also have freeware edition for basic needs.
I have been using Installshield almost a decade by now.
