I'm tasked with building a UI testing library for our application. It will allow testers to write simple programs (using VB or C#) to test our application. Instead of referencing controls via pixel position or resource ID, it will use GUIDs or names so that tests don't break everytime a minor change is made to the GUI.

1) Should I use Active Accessibility 2.0 or Vista UI Automation?

2) Is UI Automation available yet? If so, how do I access it?

3) Will it ever be supported on XP?

Thanks in advance,

John
