DbBase::AssertQuery(const std::wstring & q)
there was a recurrence calling (the method called itself)
we don't need a method which get a wstring as an argument
added: DbBase::AssertQuery(const char * q, ExecStatusType t)
DbBase::AssertQuery(const DbTextStream & query, ExecStatusType t)
(AssertQuery with a second argument -- the same as to AssertResult)
we don't have to use AssertQuery and AssertResult
only one AssertQuery now
added: to plugins: two messages:
// preparing a current user to logout
// send from 'logout' winix function
// !! IMPROVE ME this message can be sent when winix is making the shutdown
// (for sessions which are not mark as 'remember me')
// and when the SessionManager deletes a session (from the special thread)
#define WINIX_PREPARE_USER_LOGGED_OUT 30610
// a user has been logged out
// send from 'logout' winix function
// in l1 you have the old user_id
// !! IMPROVE ME this message can be sent when winix is making the shutdown
// (for sessions which are not mark as 'remember me')
// and when the SessionManager deletes a session (from the special thread)
#define WINIX_USER_LOGGED_OUT 30620
