Application variable inside trigger

Hi,

my application use some COM objects and each of them own TADOConnection
component.
Objects are connected to MS SQL Server, where is located database with some
tables and
stored procedures. Some of the tables has triggers. I need access some
specific variables
from application inside trigger.

Is this possible ?

Thanks
