  Reuse has been mentioned, but I'm not sure anyone
mentioned encapsulation. What makes it a class is that
the scoping renders it an object. I often use classes
in VBScript, where their role is more clear due to the
simplicity. It just involves adding the class at the end
of a script:

Class Something

End Something

  The public scope is visible from inside the class. The
class's private scope is not visible from outside. So
you can design an interface of your choice by creating
public methods in the class. And it's self-contained, so
you can reuse it without needing to adapt the rest of
the project. For instance, I can add a class to
encapsulate Registry operations, then create that
as an object in my script, then call very simple and
sensible functions of my own design from the script
code.

| Hello,
|
| I have tried, trust me, to learn what a class is in VB and in spite of
| many an attempt I remain baffled and I was wondering if you could help
| me out. In addition to reading I have watched YouTube videos.
| I know that fish is a class and so a trout is an instance of the class
| fish. I also know that a class contains a function and data. I better
| leave it at that because of how confused I am about the whole thing.
| I just want to add that when I posted recently about the Beep Function
| I went on to say a lot of things about M$ but I want you to understand
| it was not my intention to upset but it was my motivation to
| contribute to the life of this newsgroup. It was my rather camouflaged
| effort to thank, believe it or not, MIke Willams for helping me out
| with two great blocks of code. I realise you might not understand that
| but I didn't want to pop up out of nowhere to then disappear back into
| depths of cyberspace without making an effort to add something.
