Extract transaction logging

Hi,

Is it somehow possible to extract the transaction logging?
Once a day I want to get a report with:
- the insert,delete,update transactions;
- who (user) did the transaction;
- time and date of the transaction;

Secondly, how can I determine which user is locking a record?
Sometimes a user left his dialogbox open on an update transaction.
I want users who also wants to update that record, get a message
"record locked by .....(user)"

And last...
How can I present the errormessages in 'Dutch' to the users.


TIA

Willem
