Advanced PowerBuilder

Debugging, Tracing & Profiling

Often applications don't work as you expect them to. You may come across unexpected loops, MessageBoxes that don't appear or simply when it refuses to display the correct message. As you write script for events, you probably will be able to follow the execution flow, as you would in traditional programming.

However, there may be cases where you lose the thread, especially when using inheritance or multiple instances of objects. As object oriented programs get complex, and when advanced language features are used more often, debugging becomes exponentially complicated. When it gets to this level, it becomes imperative to see how PowerBuilder executes the script.

This session explains program debugging in PowerBuilder and some common situations where you see 'remarkable' behaviors whilst running or debugging an application.

In this session you will learn:

• The debugging environment.
• Some common debugging problems.
• Some advanced debugging techniques.
