To add an component, right click on toolbox -Choose Items -Check a
component from .NET or COM tab then click OK. It should be added if
it's .a vaid NET or COM component.

Thanks,

A Class is primarily just a bundle of code.

A Component is a kind of Class.
A /Control/ is a kind of Class.

In this case, the important difference is between Component and Control.

A /Control/ can be seen by the user; a /Component/ cannot.

For Example:
Controls: TextBox, RadioButton, Label
All things the user can /see/.

Components: Timer, TooltipProvider, MainMenu
You might see the /effect/ of one of these, or another Control that
hangs off of them, but you can't actually get to see one on its own.

To create a Component, create a class that inherits from
System.ComponentModel.Component.

To add it into (/any/ section in) the ToolBox, right-click inside that
section and select Add/Remove.
