In many of the topic's i have read about CSO library.
1. What kind of functions are there or what advance features it has.
2. How can i get access to it.
I am using evaluation copy of winrunner can some one help.
There's a solution for every problem, it depends how quick you want it
If it is critical for your evaluation of WinRunner, then you can request the item from your Mercury Interactive Sales Engineer or Mercury VAR with whom you are working during your evaluation. During a proper evaluation sponsored by Mercury or a Mercury VAR you should have access to support for any questions. Be sure and aks your primary contact for information on the identity to use when calling in or signing onto the support website.
And a quick note, there is no such thing as an evaluation copy, only an evaluation key. The product itself is absolutely the same. Also, if you did not receive the copy directly from Mercury or a Mercury VAR, then you are a software pirate. Yep, that even holds true if Orange or Pear from down the hall shared install media with you from their legitimate installation of WinRunner.
