VB.NET Programming. Intermediate Lesson 4. Built in Functions

This is the fourth in a series of computer science video tutorials for intermediate Visual Basic programmers who have completed the beginner’s series of video tutorials or are already familiar with the VB.NET syntax for the fundamental programming constructs. In this lesson you will learn about a number of built in functions that come with VB.NET. You will see how a function can be called, either by assigning the function’s return value to a variable, or by incorporating the function call in the condition part of an if statement. You will also how multiple functions can be called at once by means of nested function calls. It is important to understand how built in functions can be called before attempting to write your own functions. You will meet several different built in functions in this video; some for handling strings, some for numbers and other for performing data type conversions.
