Application targets

There are three wizards for creating application targets:

You use the Application Target wizard to create a new PowerScript-based Application object and the library containing it. You must create any other objects you need from scratch.

You use the Template Application Target wizard to create a PowerScript-based application, the library containing it, and a set of basic objects and scripts. If the application requires a connection to EAServer or a SQL database, the wizard automatically creates a Connection object.

In the Template Application wizard, you can choose one of two application types: MDI Application and SDI Application.

• Application object

• Frame window

• Frame menu

• Base sheet window

• Sheet menu

• Sheet menu service object

• Sheet windows

• About window

• Toolbar window

• Connection service object (if database connection is needed)

• Project object (optional; can build later using a Project wizard)

You can run the MDI application immediately by clicking the Run button on the PowerBar. You can open sheets, display an About box, and select items from menus. The To-Do List can help you use the application as a starting point for continuing development of an MDI application.

For information about building MDI and SDI applications, see Application Techniques.

You use the Existing Application Target wizard to add a target to your workspace that uses an application you built in an earlier version of PowerBuilder. After you complete the wizard, the Migrate Application dialog box opens so you can migrate the application to this version.

You can use the Migration Assistant to check for obsolete syntax in your application before you migrate; then you can make changes in the earlier version of PowerBuilder and avoid some migration errors. The Migration Assistant is particularly useful if you are migrating from PowerBuilder 6 or earlier. Open the Migration Assistant from the Tool tab of the New dialog box, and press F1 if you need help in the wizard.

You should also check the release notes for the version of PowerBuilder that you are using to find out if there are any migration issues that might affect you.
