how to capture dynamic images

in my application i hv to capture a dynamic images

You’re going to have to provide more details on what it is that you are trying to do. You can capture images from the SUT using the CaptureScreen command, but if you’re going to try to use the captured image later in your script then there’s more to it.

Thanks for this EggplantMatt.
If I may add a question along these lines.

I’d like to be able to check whether my ‘clear’ action actually clears up all texts in the field in a screen.

Can I use the CaptureScreen to capture a ‘clean’ screen before I populate it with text. After populating, i would then do the clear action. Here, I want to compare if after the clear action, I still have a ‘clean’ screen.
