Introduction to VB Functions

Functions are similar to normal procedures but the main purpose of the functions is to accept certain inputs and pass them on to the main program to finish the execution. They are two types of function, the built-in functions(or internal functions) and the functions created by the programmers.

The general format of a function is
functionName(arguments)
where arguments are values that are passed on to the functions.
In this lesson, we are going to learn two very basic but useful internal functions, i.e. the MsgBox( ) and InputBox ( ) functions.

MsgBox ( ) Function
The objective of MsgBox is to produce a pop-up message box and prompt the user to click on a command button before he /she can continues. This message box format is as follows:

yourMsg=MsgBox(Prompt, Style Value, Title)
The first argument, Prompt, will display the message in the message box. The Style Value will determine what type of command buttons appear on the message box, please refer Table 10.1 for types of command button displayed. The Title argument will display the title of the message board.
