There are three wizards for creating PowerScript 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.
MDI Application The wizard automatically generates the shell and scripts for a basic Multiple Document Interface (MDI) application that includes these objects:
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.
SDI Application In the Template Application wizard, you can also choose to create an SDI application. An SDI application has only one main window with a menu and an about window. If the application requires a connection to EAServer or a SQL database, the wizard automatically creates a Connection object.
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.
Before you migrate Always make a backup copy of all the PBLs used in an application before you migrate it to a new version of PowerBuilder.
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.
For more information about migrating targets, see “Migrating targets”.
