Considered the joke icon on this, but no... I'm sure he's got at least one point, but I'm certainly not searching for it. Already seen too many haystacks, and I don't need another needle. ;P

The cases are listed alphabetically. But they forgot two of them: case "M" and case "V". Maybe that's the reason why their chemical facility burnt down...

I thought his subject line made it quite plain what he regarded as wrong here: Don't Repeat Yourself - There's a lot of copy-and-paste style repetition all over that method. Separation of Concerns - This one method seems to cover a lot of ground. Inversion of Control - This looks like classical procedural code to me. Keep It Simple Stupid - 'nuff said. Generally, any method over 20-30 lines should often be regarded as suspect. This is a true horror.

You're right, PIEBALDconsult. Excuse me for this, okay? (Sorry, guys!) I wanted to give a dramatic effect and, as a big fan of Tarantino, exaggerate the amount of blood. :) I have this code posted on a blog on wordpress. You think I should edit my post and replace the entire code for a link pointing to the post in wordpress?

Good idea! I hadn't thought of that... use CP as an offsite backup facility. Hmmm. I wonder if the hamsters will complain...

makumazan84, when PIEBALDconsult talked about blood, I thought that exact scene you described. Kill Bill is a masterpiece ... and the code, of a very particular way, it is also. As you get dizzy, I think in Visual Studio that could be solved with several sections #region. :cool:

hmmm...in VS2003 and in VS2008SP1, you can't define #regions within a function body

Yeah, I had the same reaction the first time I wanted to use it, some time about two years ago. I dislike large function bodies, but realistically there are a number of situation-specific algorithms that depend on a long sequence of unrepeated operations. To reduce the size, one is left with the option of breaking them into smaller chunks as subroutines, then calling each subroutine in sequence. I've seen differences in how well that approach works when maintenance is being performed by novices to the software. I've seen genuinely intense frustration expressed by some developers when they have to nest down through two or more levels of subroutine that were simply put in to eliminate very lengthy code sequences, where the developer in question felt it would have been much easier to follow the sequence in its original lengthy form. Allowing collapsible regions within a subroutine brings the best of both techniques to bear on the problem.
