Alternatively, you can use Update(). For the example, the only real difference is that Update() can be called after the state of the item has been modified, which would be the case if the administrator made changes before approving the auction: public ApproveAuction(Item item, User admin) { item.Approve(admin); itemDAO.MakePersistent(item); } c# ean 13 reader .NET EAN-13 Barcode Reader for C#, VB.NET, ASP.NET Applications

There is a special rule disabled by default that you can select in the Report Model Wizard to create attributes only for columns that contain data. By enabling this rule, you won t have to perform an extra step to delete unnecessary attributes later. In this procedure, you ll use the Report Model Wizard to generate a report model from the rs2005sbs DW DSV you created in the previous procedure. Use the Report Model Wizard 1. Right-click the Report Models folder in Solution Explorer, and then click Add New Report Model. 2. Click Next on the welcome page of the wizard, ensure that Rs2005sbs DW.dsv is selected on the Available Data Source Views page, and then click Next.

Again, NHibernate performs a version check when updating the item. Is this implementation, using detached objects, any simpler than the load-objectson-every-request approach You still need an explicit call to the ItemDAO, so the point is arguable. In a more complex example involving associations, you ll see more benefit, because the call to Lock() or Update() may cascade to associated instances. And let s not forget that this implementation is more efficient, avoiding the unnecessary SELECTs. Nevertheless, we re not satisfied. Is there a way to avoid the need for explicit reassociation with a new session One way is to use the same NHibernate session for both database transactions, a pattern we described in chapter 5 as session-per-conversation or long session. c# ean 13 reader Creating EAN-13 Barcodes with C# - CodeProject

A long session is an NHibernate session that spans a whole conversation, allowing reuse of persistent instances across multiple database transactions. This approach avoids the need to reassociate detached instances created or retrieved in previous database transactions. A session contains two important kinds of state: a cache of persistent instances and an ADO.NET IDbConnection. We ve already stressed the importance of not holding database resources open across multiple requests. The session needs to release its connection between requests if you intend to reuse it in the many web requests that may span the conversation. As explained in section 5.1.4, NHibernate 1.2 keeps the connection open from the first time it s needed to the moment the transaction is committed. Committing the transaction at the end of each request is enough to close the connection. You don t want that, because a closed session is useless in subsequent transactions. Listing 10.5 used the web context to store the session. This strategy uses HttpContext, and the session lives only as long as the request. How do you make your session usable across multiple requests The simplest solution is to keep the NHibernate session in the ASP.NET session state, so that it s available from one request to another. You ll use this approach in the following example. Let s write a new web module called NHibernateConversationWebModule (see listing 10.6). It will store the NHibernate session between requests instead of discarding it. It will also handle the reattaching of the session to the new context. public class NHibernateConversationWebModule : IHttpModule { const string NHibernateSessionKey = "NHiA.NHibernateSession"; const string EndOfConversationKey = "NHiA.EndOfConversation"; public static void EndConversationAtTheEndOfThisRequest() { HttpContext.Current.Items[EndOfConversationKey] = true; } public void Init(HttpApplication context) { context.PreRequestHandlerExecute += new EventHandler(OnRequestBeginning); context.PostRequestHandlerExecute += new EventHandler(OnRequestEnding); } public void Dispose() { } private void OnRequestBeginning(object sender, EventArgs e) { As you can see here, there are many rules used to generate a report model. You can learn more about the purpose of each rule at http://msdn2.microsoft.com/en-us /library/ms183622.aspx. 3. Keep the default selections on the Select Report Model Generation Rules page, and then click Next. Since you just created a DSV, the statistics in that file are current. 4. On the Collect Model Statistics page, select Use Current Model Statistics Stored In The Data Source View. ISession currentSession = (ISession)HttpContext.Current.Session[NHibernateSessionKey]; if (currentSession == null) { currentSession = NHibernateHelper.OpenSession(); currentSession.FlushMode = FlushMode.Never; } CurrentSessionContext.Bind(currentSession); currentSession.BeginTransaction(); ] private void OnRequestEnding(object sender, EventArgs e) { c# ean 13 reader Read & Decode EAN-13 Barcode Using C# Class Code in .NET ...
