Answer 1

Having struggled with this type of this a few times before, i would suggest a couple of things to look at.

The 1st is autoit which includes a dll you can reference from vb.net, and is very simple you use, and well documented. I tend to use that whenever i need to control a 3rd party program.

The other is the ui automation classes See this for an example:
