hi..
I am newbie of nhibernate.
I build winform application using Nhibernate which has add/delete/edit/retrieve process, but I am not understand when to open session or close session or clear session.

I used open session on event Load Form and close when I unload form. but the effect ever time I retrieve data I should clear session first and then retrieved because if I did not clear session, system will retrieve not live data(after I updated or add new).


but I got example on google.they put open session and close session on process/function. like:
public sub retrieved_all()
Dim sessionfactory As ISessionFactory = New Configuration().Configure().BuildSessionFactory
session = sessionfactory.OpenSession
'....retrieved process
session.close()
end sub


could everyone help me when to use open/clear and close session

thanks for your helping
