Creating a Window Using the Windows API

The Windows API is used to create windows for forms in Visual Basic. These forms have properties such as title, custom text and other features such as forecolor and backcolor. Users can create and destroy windows on forms. API functions are declared before being used or implemented. You must declare functions as private to use on forms.
