What are 'Classes' and 'Client Application'?

[VBNubcake]

Classes (in the OOP sense) is a datatype that has methods and/or variables attached to it.
Example:
var.dosomething()
var.var.
Afaik, they do NOT exist in VB6. However, they are in VB .Net.
However, I do believe VB6 has the ability to declare structs. Structs are just definitions for a datatype.
Example:
(C++ example)

struct pos {
int x;
int y;
};
pos coord;
coord.x = 5;

My computer science professor defined classes as structs on steroids.
Client application is just the people who use your application on your computer (ie as a client).

thx for that post - helped
