Thanks for your answer.
I didn't mean to post data with the event
but to post an event named after the data contained in a field.
If for example a field named 'personid' has value (in the new record
after an insert) 'P123' then to post an event with name
P123. Ofcource this is done. The problem is when the field data
contains greek letters it doesn't post. But as you
said the name of the identifiers can contain only US ASCII chars.
I should have thought of that.
Anyway IBPP is a C++ wrapper of the firebird API and its the
fastest way to work with firebird.
Thanks a lot
