Of course, you can perform certain customizations using the various wizards provided by Access. When a wizard won't do, your next option is to write an Access macro. However, there are certain customizations that must be implemented by writing VBA procedures. As the text indicates, there are different types of procedures. The simplest is the event procedure , which is a collection of instructions, called a code block, which Access executes when a certain event occurs.
Events occur when a user clicks the mouse button, selects a field in a form, closes the form, etc.
Other procedures include functions and subroutines. For this tutorial, it is absolutely critical that you carefully read over the entire tutorial rather than simply following along with the gray instruction boxes. Otherwise, you won't really understand what you will be doing, and the case won' t make any sense to you. These procedures are usually stored in a module or modules. So, this week you will finally get to work with the Modules section of the Objects window.
