I am planning to write an automatic testing program using Robot
class. I get a more information from your tutorials. I have one more
doubt in the Robot class. Is it possible to locate a component (for
example a button) by specifying the component name or some caption of
the button? I am not sure about it. Because currently I am accessing
a component only by getting the x and y coordinate of the component.

So can you please mail me about this? Expecting some replay from you.

Even if you give some links regarding this then it is ok for me.
