Although you can create the messaging server as a separate application, it s tidier to place it in the same application as the policy server Because the policy server does its listening and request-handling work on separate threads, the messaging server can do its work at the same time Like the policy server, the messaging server is broken into two classes: MessengerServer, which listens for requests and tracks clients, and MessengerConnection, which handles the interaction of a single client To see the full code, refer to the downloadable examples for this chapter In this section, you ll explore the differences between the policy server and messaging server First, the messaging server performs its listening on a different port As described earlier, Silverlight allows socket-based applications to use any port in a limited band from 4502 to 4534 The messaging server uses port 4530: listener = New TcpListener(IPAddress.

QuantityInBin smallint NOT NULL, QuantityOnOrder smallint NOT NULL, QuantityToPull smallint NOT NULL, PartialFillFlag nchar(1) NOT NULL, PRIMARY KEY (SalesOrderID, ProductID, LocationID, Shelf, Bin) ) You may notice that I ve defined a primary key on the table result. This also serves as the clustered index for the result set. Due to limitations in table variables, you can t explicitly specify other indexes on the result set. The body of the function begins with the INSERT INTO and SELECT clauses that follow: INSERT INTO @result ( SalesOrderID, ProductID, LocationID, Shelf, Bin, QuantityInBin, QuantityOnOrder, QuantityToPull, PartialFillFlag ) SELECT Order_Details.SalesOrderID, Order_Details.ProductID, Inventory_Details.LocationID, Inventory_Details.Shelf, Inventory_Details.Bin, Inventory_Details.Quantity, Order_Details.OrderQty, COUNT(*) AS PullQty, CASE WHEN COUNT(*) < Order_Details.OrderQty THEN N'Y' ELSE N'N' END AS PartialFillFlag These clauses establish population of the @result table variable. The most important point to notice here is that the return results of this multistatement TVF are created by manipulating the contents of the @result table variable. When the function ends, the @result table variable is returned to the caller. Some other important facts about this portion of the multistatement TVF are that the COUNT(*) AS PullQty aggregate function returns the total number of each item to pull from a given bin to fill a specific order detail row, and the CASE expression returns Y when an order detail item is partially filled from a single bin and N when an order detail item is completely filled from a single bin.

Visual Basic 2005 supports a specific programming construct termed a Module. For example, when you create a console application using Visual Studio 2005, you automatically receive a *.vb file that contains the following code: Module Module1 Sub Main() End Sub End Module Under the hood, a Module is actually nothing more than a class type, with a few notable exceptions. First and foremost, any public function, subroutine, or member variable defined within the scope of a module is exposed as a shared member that is directly accessible throughout an application. Simply put, shared members allow us to simulate a global scope within your application that is roughly analogous to the functionality of a VB 6.0 *.bas file (full details on shared members can be found in 5). Given that members in a Module type are directly accessible, you are not required to prefix the module s name when accessing its contents. To illustrate working with modules, create a new console application project (named FunWithModules) and update your initial Module type as follows: Module Module1 Sub Main() ' Show banner. DisplayBanner()

Any, 4530) When the messaging server receives a connection request, it performs an extra step As with the policy server, it creates an instance of a new class (in this case, MessengerConnection) to handle the communication Additionally, it adds the client to a collection so it can keep track of all the currently connected users This is the only way you can allow interaction between these clients for example, allowing messages to be sent from one user to another Here s the collection that performs the tracking, and a field that helps the server give each new client a different identifying number: Private clientNum As Integer Private clients As New List(Of MessengerConnection) When the client connects, this code creates the MessengerConnection and adds the client to the clients collection: clientNum += 1 ConsoleWriteLine("Messenger client #" & clientNumToString() & " connected.
