By way of thanks to Tim (who helped with the flash code) and Mark (who
posted the CastTo clue last year) here's a working example that:
- opens a browser
- navigates to google
- finds the query tag
- flashes it
- finds the button tag
- flashes it
Thanks for your help.
If anyone wants to use it, know that I've not tested the code extensively.
The usual disclaimers about fitness definitely apply.
BTW, there's an interesting bit of fuss in getting the tag's screen
coordinates. It turned out to be a bit trickier than I'd expected.
Regards,
Richard
