    <p>I have a problem with receiving messages from a queue i have set up in azure. I have done this successfully using the same code before but now i just get null when i try to fetch messages. When i view the queue in azure management console i clearly see that the queue contains 5 messages.</p> <p>Here is the code:</p> <pre><code>ServiceBus SB = new ServiceBus(); Microsoft.ServiceBus.Messaging.BrokeredMessage message; while (true) { message = SB.ReceiveMessage("orders"); if (message == null) { break; } Procurement.Order order = message.GetBody&lt;Procurement.Order&gt;(); order.id = Guid.NewGuid().ToString(); order.remindercount = 0; using (DbManager db = new DbManager()) { if (db.SetSpCommand("CreateOrderHead", db.Parameter("@companyId", order.companyId), db.Parameter("@orderId", order.orderId), db.Parameter("@suppliercode", order.suppliercode), db.Parameter("@supplierorderId", order.supplierorderId), db.Parameter("@orderdate", order.orderdate), db.Parameter("@desireddate", order.desireddate), db.Parameter("@ordertext", order.ordertext), db.Parameter("@name", order.name), db.Parameter("@street", order.street), db.Parameter("@zip", order.zip), db.Parameter("@city", order.city), db.Parameter("@country", order.country), db.Parameter("@countrycode", order.countrycode), db.Parameter("@deliveryterms", order.deliveryterms), db.Parameter("@reference", order.reference), db.Parameter("@deliveryinstruction", order.deliveryinstruction), db.Parameter("@id", order.id), db.Parameter("@partycode", order.partyCode) ).ExecuteNonQuery() == 1) { message.Complete(); message = null; } db.SetSpCommand("DeleteOrderRows", db.Parameter("@orderid", order.orderId), db.Parameter("@companyId", order.companyId) ).ExecuteNonQuery(); foreach (Procurement.Orderrow r in order.Orderrows) { db.SetSpCommand("CreateOrderRow", db.Parameter("@companyId", r.companyId), db.Parameter("@orderId", r.orderId), db.Parameter("@orderrowId", r.orderrowId), db.Parameter("@itemId", r.itemId), db.Parameter("@itemdesc", r.itemdesc), db.Parameter("@orderqty", r.orderqty), db.Parameter("@desireddate", r.desireddate), db.Parameter("@rowtext", r.rowtext), db.Parameter("@supplieritemId", r.supplieritemId), db.Parameter("@unit", r.unit), db.Parameter("@id", order.id), db.Parameter("@unitprice", r.unitprice), db.Parameter("@rowprice", r.rowprice) ).ExecuteNonQuery(); } } } Thread.Sleep(new TimeSpan(0, 1, 0)); </code></pre> <p>And this is the ServiceBus-class:</p> <pre><code>public class ServiceBus { TokenProvider TokenProvider; MessagingFactory Factory; public ServiceBus() { TokenProvider = TokenProvider.CreateSharedSecretTokenProvider(GetIssuerName(), GetSecret()); Factory = MessagingFactory.Create( GetURINameSpace(), TokenProvider ); } public void SendMessage(string queue, BrokeredMessage message) { var client = Factory.CreateQueueClient(queue); client.Send(message); } public BrokeredMessage ReceiveMessage(string queue) { var client = Factory.CreateQueueClient(queue, ReceiveMode.ReceiveAndDelete); BrokeredMessage message = client.Receive(); return message; } private static Uri GetURINameSpace() { return ServiceBusEnvironment.CreateServiceUri("sb", GetNamespace(), string.Empty); } private static string GetNamespace() { return "Namespace i have verified its the right one"; } private static string GetIssuerName() { return "Issuer i have verified its the right one"; } private static string GetSecret() { return "Key i have verified its the right one"; } } </code></pre> <p>I think this should be pretty straight forward but i cant find out what im doing wrong. Its probably something small that im missing...</p> <p>Anyways, thanks in advance!</p>

    1. COSolved it myself! Either azure management-portal showed the wrong number of messages on the queue or the messages where still on the queue but marked as "Done" or something.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
