There may be situations where it is necessary to operate with a table that does not belong to a database, or where a session or database dictionary file is not required. For these situations the user may want to create a session object of type CTSESSION_CTREE.
// create a session object without dictionary support
CTSession ASession(CTSESSION_CTREE);
// Logon to a session
try
{
ASession.Logon("FAIRCOMS", "ADMIN", "ADMIN");
}
catch (CTException &err)
{
printf("Session logon failed with code %d\n", err.GetErrorCode());
}
The CTSession::Logon() call above will perform a c-tree logon but it will not attempt to open a session dictionary file. The same result is obtained if a normal CTSESSION_CTDB or CTSESSION_SQL session is allocated but the method CTSession::SetLogonOnly() is called before CTSession::Logon().
// create a session object without dictionary support
CTSession ASession;
// Logon to a session
try
{
ASession.SetLogonOnly();
ASession.Logon("FAIRCOMS", "ADMIN", "ADMIN");
}
catch (CTException &err)
{
printf("Session logon failed with code %d\n", err.GetErrorCode());
}
