PowerBuilder Knowledge Test

Twenty questions, 19 with one correct answer and 1 with several. The candidate does not write code; the test asks how the environment and its objects work.

Several questions focus on the DataWindow, the object that connects an application to the database, along with PowerBuilder-specific conventions. It is not a general programming test.

What it measures

• The PowerBar, the StyleBar and the Script views in the application painter

• DataWindow objects: retrieving data, deleting rows and the dropdown style that reads from the database

• Passing arguments by value or by reference, and which values can be changed

• Variable scope: values that persist and variables accessible from anywhere

• Reusable, inheritable components and window inheritance

• Naming prefixes such as li_ and where objects are stored

Ideal for

• PowerBuilder developers

• Teams that maintain existing PowerBuilder applications

• Candidates for roles that extend data-centric desktop applications
