Get raw data of application gui

Is there a way to access the internal data which a program (not matlab, running on my computer (Mac)) is sending to the prgrams gui? I want to use it for further analysis/calculations.

Can somebody point me in the right direction.

If not is there a slicker way than getting the data with ocr?

Are you trying to intercept data that another application (outside of MATLAB) is processing? Please provide more details...

Yes, thats exactly it. Didnt know how to phrase it as I dont know much about it in general.

[Geoff Hayes]

Well I don't think that you can intercept what is going from the device to the other app unless you connect to that device through MATLAB or that app allows the data to be exported...and if you do the former, that will depend upon the type of device you want to connect to and whether you need a MATLAB toolbox for support. YOu may need to provide more details surrounding the device that you are interested in connecting to....

Just as an example, this stock program:

Is there a way to pull out the numerical data which is displayed on the gui by ways of accessing the internal program data (or other ways (but not ocr))?

(I know there are api's to get the raw stock data, this is just as an example)

[Geoff Hayes]

Unless the application provides some mechanism to export the data then I suspect that you can't do what you want...
