Visual Basic Concepts

Working with Objects

When you create an application in Visual Basic, you work with objects. You can use objects provided by Visual Basic — such as controls, forms, and data access objects. You can also control other applications' objects from within your Visual Basic application. You can even create your own objects, and define additional properties and methods for them.

The following topics discuss objects in detail:
