The Data control does a lot for you "behind the scenes" and you may be tempted to use it in your applications, but be advised that the Data control is rarely used in professional applications – the norm is to write your own database access code so that you have complete control over the process.These exercises are worthwhile in that you can see what data bound controls are all about, but again be advised that they should not be used for professional application development. On a default installation of VB6, these databases can be found in the folder: C:\Program Files\Microsoft Visual Studio\VB98.The Action argument tells you which particular action (Move First, Update, etc.) caused the Validate event to fire.

Database Name is the name of the database you want to use, and the Record Source is the name of the table in that database that you want to use.3.

On your form, create a text box for each field in the Authors table, with labels.

This means that any code contained in the Validate event procedure will be executed prior to the execution of a statement containing one of these methods.

For example, if somewhere in your program you code the statement dat Authors. Update, when VB encounters this statement, any code in the Validate event will be executed first.

In addition to being invoked automatically through the data control, the Update and Add New methods can also be invoked through code.
