General Procedures and DLLS

A procedure is a collection of program statements that behave as a unit. In Visual Basic the procedures that deal with the events that happen, such as buttons being clicked or text being typed, are called event procedures. All other procedures are called general procedures. Procedures are defined as either SUB or FUNCTION, which behave in slightly different ways. In this chapter you will learn about: Event and general procedures. SUB procedures. FUNCTION procedures. Naming conventions. How to declare DLLs. How to call DLLs.
