Subject Re: [firebird-support] Post_Event with 2 parameters
Author Kamlesh
dear friend

i've not tried and i m not sure how it will work but u can try following
till fb2 (i hope)

u will have to register 37+ events i.e.'A' to 'Z', '0' to '9' and
terminator character(';') and some special characters if u need and then u
can prepare a message out of those chatacter

prepare and post such event
something like following if u want to send 'TableUpdate', 'Customers-12345'


POST_EVENT 'T'
POST_EVENT 'A'
POST_EVENT 'B'
POST_EVENT 'L'
POST_EVENT 'E'
POST_EVENT 'U'
POST_EVENT 'P'
POST_EVENT 'D'
POST_EVENT 'A'
POST_EVENT 'T'
POST_EVENT 'E'

POST_EVENT 'C'
POST_EVENT 'U'
POST_EVENT 'S'
POST_EVENT 'T'
POST_EVENT 'O'
POST_EVENT 'M'
POST_EVENT 'E'
POST_EVENT '-'
POST_EVENT '1'
POST_EVENT '2'
POST_EVENT '3'
POST_EVENT '4'
POST_EVENT '5'

POST_EVENT ';' // --- terminator at the end of message


at client application u can reprepare this message and analyze
its better to use short form message like 'TUCUS12345' rather than
'TableUpdate', 'Customers-12345';

well, u can prepare from such message only if u receive those event in there
posted sequence ( i m not sure of that and i think such operation may affect
performance)

well, its just a kids way , u should use tcp sockets for such communication
or that kind of third party components.
