Control and Component

Question

Hi

I am beginner learning C#.

Can any one explain me what is the difference between User-Defined Component and User-Defined Control?

Answer 1

The term component in the software industry is often used to refer to a reusable object that exposes one or more interfaces to clients in a standardized way. A component may be implemented as a single class, or as a set of classes; the primary requirement is that the basic public interface be well-defined.

Answer 2

Use a Control if you want something visible at runtime.  Use a Component when you just want to take advantage of the Properties window in the designer.  Components can have a visible runtime presentation too, but that takes a *lot* of code.
