focus and select

[nadim khemir <nadim khemir net>]

given a dialog that looks like this:

.-------------------------.
|.-------.-------.-------.|
|| Table | Table | Table ||
|.-------.-------.-------.|
|| Table | Table | Table ||
|'-------'-------'-------'|
|.-----------------------.|
|| Text box 1            ||
|'-----------------------'|
|.-----------------------.|
|| Text box 2            ||
||                       ||
|'-----------------------'|
'-------------------------'

How can I focuse "Text box 2" and select its text so the user can start 
modifying it directly?

Cheers, Nadim
