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 SESSION_TYPE.CTREE_SESSION.
// create a session object without dictionary support
CTSession ASession = new CTSession(SESSION_TYPE.CTREE_SESSION);
// Logon to a session
try
{
ASession.Logon("FAIRCOMS", "ADMIN", "ADMIN");
}
catch (CTException err)
{
Console.Write("Session logon failed with code {0}\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 SESSION_TYPE.CTDB_SESSION or SESSION_TYPE.SQL_SESSION session is allocated but the method CTSession.SetLogonOnly() is called before CTSession.Logon().
// create a session object without dictionary support
CTSession ASession = new CTSession();
// Logon to a session
try
{
ASession.SetLogonOnly();
ASession.Logon("FAIRCOMS", "ADMIN", "ADMIN");
}
catch (CTException err)
{
Console.Write("Session logon failed with code {0}\n", err.GetErrorCode());
}
