I wrote an Excel vba function that will take a string argument and return a string that is legal for naming a range. Upon looking through this, if you're wondering what I've been smoking, I should add a disclaimer that I'm new to vba and I have not yet come across a less restrictive way to obtai...
A while ago I implemented .net's string.Format() method in VB6; it works amazingly well, but I'm sure there has to be a way to make it more efficient.

Even though it's the first time I'm writing something this "big", it feels like I know C# quite good. It's been nice to learn LINQ also and I am very impressed by the features, and perhaps I have overused it here (if it's possible to do that).
