How to iterate over all the records of a block in a trigger

Hi,

Pleas consider the following situation:

I have a block, bounded to a DB-table, that contains some extra
unbounded fields (checkboxes). The user is allowed to alter the
contents of these extra fields (check the boxes). After the selection
is done, I would like to press a button and build a list containing
the records which where checked by the user.

I tried different ways of calling the getResultSet method,
first-/nextRecord and so on, on different objects (blokname, form,
etc. ) but always got an exception from __getattr__.

How can I do this?

Another question about Python. How can I see what kind of object
(which class it corresponds) a referenced object (like self) is? In
perl I just can put a "print $obj;"  and I get its class name, but in
python this seems not to work.

Regards

Andreas
