Are you talking about the control itself changing, or the data the control is displaying? You need to be clearer on that point as what you have stated, when read, is that the control object is changing every second. You would be hard pressed to find any tool which can handle that scenario.
Now, why are you trying to automate a control that is changing every second? What is the control? What is the technology your application is built on?
With such vague first post, what is your experience with WinRunner? tutorial/training/mentoring? How many years, with the tool have you had? Some of us would have ideas, but without the fore-knowledge of your experience we might come off on the wrong footing.
