Prior to starting development of a suite of test cases I will analyse the test cases and verify those that are suitable for automation and those that aren't. The Test manager will also have an oppinion on this as I do not know the business importance of all test cases.
IMHO this is one where I would say probably not automate if I had a choice. Not sure how long you have spent researching how to do this in QTP but I bet you could have done it manually 100 times in the same amount of time.
I'm baffled why a small minority of test automators try to automate everything, ROI is a factor in most automators analysis and I personally think that it a good thing.
