Program Structure and Code Conventions
This section introduces the typical Visual Basic program structure, provides a simple Visual Basic program, "Hello World", and discusses Visual Basic code conventions. Code conventions are suggestions that focus not on a program's logic but on its physical structure and appearance. Following them makes your code easier to read, understand, and maintain. Code conventions can include, among others:
- Standardized formats for labeling and commenting code.
- Guidelines for spacing, formatting, and indenting code.
- Naming conventions for objects, variables, and procedures.
The following topics present a set of programming guidelines for Visual Basic programs, along with examples of good usage.
