Hi Geoff,
It is not possible to extract text from a string based on its original
screen color as the color information is not stored in the string.
It is only possible to extract text directly from the screen based on its
color, as the functions that do this assess the color of each character
before determining whether to add that character to the string that will be
the result of the function such as GetTextRect when using the color options.
To do what you want with the substituation of the commas may be possible,
but would take a lot of work, as somehow you would need to pick up the
section of the screen to retain the tabs, then pick up the text based on
color, and mainipulate the result by comparing the 2 strings. Not a
straightforward task.
Regards,
Paul

Hey mighty scripters.
I think I sent this one late last week, but didn't get any nibbles on it so
am trying again. if any kind soul could give me a hand instituting this one,
it'd be heaps appreciated.
Also, may I add one more queery to the top?
What's the bestest function for announcing only the text of a certain color,
from a string?
i.e. I do a couple of getLines() and concatinate them into a string, in
order to retain tab Characters which I need to remain so I can replace them
with commas for pauses,
and then I wanna say, let that string only equal text that's xx on YY color.
and then just speak that data out of the string?
I know you can use special optional color parameters on GetTextInRects, but
in this case I can't use that, because it strips out the Tab Characters
automatically, and I need functions that don't do that?
Thanks for any tips ASAP on that one, and if I may, here comes the repeat of
last weeks post, which I'm still very keen to implement on the last day of
the job! ah, feature creep. gotta love it!

I have never made jaws pop up boxes for reception of user input before?
