Beyond that, I'm not fully experience with using that set of controls so I don't know specifics. The best advice I can give you is to start exploring the objects, looking for native methods and properties that will get you the node name. I believe you're going to want to find the "Caption" property.
So.... the question is:
Are you looking to find the caption of a node for which you don't already know the name?
Or are you looking to find the node that matches the captionyou already know?
The latter is easier... you loop through all the nodes using a for or while loop until you find a matching caption. The former.... not so easy.
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.
