Access VBA Programming – 3 Advantages to Using VBA Over Macros

If you have been working in Access for some time and did not add much automation to your database you probably are not satisfied. Your database needs more. It is time to write some VBA code.

Not everything you need to do with your database should be accomplished via code. Access has a variety of built-in commands that can help automate your application without writing even one line of code.

As a beginner, usually you start with the creation of a macro. This is a saved series of commands, which enables you to perform different operations. It can be attached to a command button on a form. When you click on it, the commands are then executed. You can use macros for a variety of tasks.

While they are perfectly acceptable and even recommended in certain situations, VBA has some advantages over a macro. Here are 3 advantages you will enjoy:

Speed: A one-action macro will probably execute faster than code. However, a complex one with 10 or 12 actions takes significantly longer than the equivalent code. You definitely need to be concerned with speed. If your users see the hourglass for even more than 5 or 6 seconds, their perception will be that your program is slow.

Functionality: There are only a limited number of macro actions, but VBA provides much more functionality. Some of the key functionality is the ability to interact with other applications. Using VBA, you can open a Word template and insert data from your database. You can send an e-mail message from Outlook automatically to your customer, who is listed in a table, when you are finished making an invoice.

Control: When you execute a macro, you have no other choice than to let the actions perform their work. By using code, you control each step of the process. Macros can ‘t run a different set of actions for each user, VBA can do this easily.

A good programmer knows when to write code and when to let Access do all the work. Like with many things in live, experience is the best teacher.
