Re: What is the event sender parameter and what does one do with it?
There is an ActiveX component in TestComplete that generates the events. The "Sender" is that component... basically, it needs to be there, but you don't have anything you can really, usefully, do with it that I've found.
Why automate? I do automated testing because there's only so much a human being can do and remain healthy. Sleep is a requirement. So, while people sleep, automation that I create does what I've described above in order to make sure that nothing gets past the final defense of the testing group. I love good food, good books, good friends, and good fun.
