The Data Block Wizard enables you to quickly and easily create or modify data blocks for use in your application. When you use the wizard to create or modify a data block, the wizard can automatically generate code to enforce integrity constraints in the database, and modify various properties and settings for you, giving you more time to concentrate on other aspects of developing your application.
Use the Data Block Wizard to complete the following tasks:
A powerful quality of the Data Block Wizard is its ability to operate in re-entrant mode. You can use the Data Block Wizard to modify an existing data block, even if the block was not originally created with the wizard.
To invoke the Data Block Wizard in re-entrant mode, select the existing data block in the Object Navigator (or select any item in the block in the Object Navigator or Layout Editor), then choose Tools | Data Block Wizard from the menu.
The Data Block Wizard provides six buttons to help you navigate your way through its pages:
Note: If you click Next or Back before you have entered all necessary information for a particular wizard page, the wizard prevents you from navigating to the next (or previous) page. Similarly, if you have not entered all necessary information into the wizard when you click Apply or Finish, the wizard automatically places you onto the page where you can finish entering the required data.
