SQL server readOnly

i am not able to write to a sql server db thru my vc++ application altho i can write to it w query analyzer.

my login is as user dbo, so i thought i had all permissions.

someone mentioned something about having to set up
permissions in database model before setting up the db.
could this be my problem? a TRACE statement in
my code indicates that the db connection is opened with
read/write permissions. the tables i am trying to write to
all have dbo as owner as User as Type.

any help or suggestions would be appreciated.

thanks
