how can you read displayed values?

[changewebsite]

If for example, there is a java application that generates values such
as text and numbers, how can another application read the values that
the java application diplays? Does anyone have any idea? I am working
in Visual Basic.

Are you talking about how to parse the formatted data or how to gain access
to the device upon which the data is displayed?
