What Is Control Itself And What Are Different Types Of Controls Available In Visual Basic 6.0?

A control is actually predefined object which has a visual appearance.
The user can interact with these controls/objects with mouse or keyboard.
These predefined components are reusable and are used in visual programming.
These controls act like building blocks that are combined to form an application in visual programming.

There are two types of controls in visual basic:
1. Intrinsic controls
2. ActiveX controls

Intrinsic controls are also called standard controls. These are default controls that are available at the tool box in the IDE of visual basic.For instance, check box, text box, command button, scrollbars, label, timer, option button, image, list box etc.ActiveX controls are the form of advanced controls that are actually extension of intrinsic controls.
These controls are added explicitly by the visual programmer in the project. These can be added through the project menu. Select "Components" from project menu. It will display Components dialog.

It will show a list of all ActiveX and other components that are not in the default tool box but can be added to an application.Check an ActiveX control option and press OK. An icon representing that newly selected control will be added to the tool box on the IDE of visual basic. We can add this control to our application simple as an intrinsic control.
