Application targets – PB Docs 2018

There are three wizards for creating application targets:

Application Target
wizard

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.

Template Application
Target wizard

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
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:

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 a Single Document Interface (SDI) application. An SDI
application has only one main window with a menu and an about
window. If the application requires a connection to a SQL database,
the wizard automatically creates a Connection object.

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

Existing Application
Target wizard

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 information about building standard PowerBuilder
applications, see the rest of this book and Application Techniques.
