I'm going to be blunt:

Screw all this transition crap! It's a different language! Get used to it! We programmers are a tough species. If need be, we can adapt to using MessageBox.Show instead of using MsgBox. Hell, if you still want to be using MsgBox and all those VB6 written functions, then go back to VB6! Is it so hard to use MessageBox.Show instead of MsgBox? Intellisense does all the typing for you either way if you know how to use the IDE at all.

I can understand if you are using MsgBox instead of MessageBox.Show if you learned it from a crappy tutorial, teacher, or text, but if you know that MessageBox.Show exists and your small brain can't handle typing an extra 9 characters for an object oriented, well-written, undeprecated, updated function, maybe you shouldn't be programming or using anything above VB6 to begin with.

Blowing off steam is fun!
