Abstract This article describes a powerful technique that exploits my previously outlined innovation – Function Pointers in VB Script – to build a generic mechanism having the capacity of executing components repeatedly: the generic iterator. Introduction Executing processes repeatedly is a common theme in software development, one that is at the core of

This article describes a powerful technique that exploits Object Oriented Design Patterns, QTP descriptive programming (DP) and the Dictionary object to pack together GUI objects with their corresponding business oriented functions. The article includes a valuable bonus: a highly effective tip that enables to exit a test smoothly, preventing QTP from getting stuck when it fails to identify GUI objects during runtime.
Abstract Function pointers are used in C and C++ to enable callbacks and as a result, more generic and parsimonious coding. This article shows how to implement function pointers in VB Script using the Scripting.Dictionary object and the Command Wrapper design pattern. It is also shown how to implement “constructor” functions, callbacks land event handlers.

In a previous article, I’ve discussed (among other things) the possibility of adding COM objects to the QTP reserved objects pool, thereby enabling some limited sort of intellisense for them (i.e. Syntax auto-complete). This is all very nice, but what happens when we want to do something similar with our custom classes and objects? It

Possible ByRef catastrophes The example from part 1 (regarding passing objects as ByVal parameters) might lead us to believe that when passing an object to a function, we shouldn’t care less if it’s passed ByVal or ByRef, as we’re passing the object’s reference in any case. Any change to the object within the function’s scope

A very refreshing debate at SQAForums has really opened my eyes on the small details involved with Objects, Scopes and Procedure calls. I thought it was a good idea to write a summary of what went on there, and I took the opportunity and added a very detailed background about many basic terms that may

This 14-page article by Meir Bar-Tal explains in details the benefits and inherent possibilities in wrapping our functions with classes. It further explores the meaning and logical structure of classes, and shows how we can easily implement constructors, event handlers and callback by using class composition and function wrapping. The different techniques are well illustrated
