HttpRequest creates an HTTP message by appending an HTTP header to the request to send. Note the SequenceNumber field in the header. I ll show you how to use this field later, when a response is detected, to match the response with the right request. HttpService uses a listener thread to handle responses. The code is contained in class Receiver, whose C# and VB .NET implementations are shown in Listing 12-11 and Listing 12-12. Listing 12-11. The C# Implementation of the Receiver Class public class Receiver { bool stopRequested; Socket socket; public Receiver(Socket theSocket) { socket = theSocket; } public void Stop() { stopRequested = true; } public void Run() { stopRequested = false; while (!stopRequested) CheckForIncomingTraffic(); } void CheckForIncomingTraffic() { if (socket.Available == 0) FireIdle(); else FireResponse(socket); } public delegate void ResponseHandler(Socket theSocket); public event ResponseHandler OnResponse; void FireResponse(Socket theSocket) { if (OnResponse != null) OnResponse(theSocket); } public delegate void IdleHandler(); public event IdleHandler OnIdle; void FireIdle() { if (OnIdle != null) OnIdle(); } } asp.net mvc qr code How to generate QR codes with ASP .

Whereas rows of data in a heap table are stored in an unorganized fashion (data goes wherever there is available space), data in an IOT is stored and sorted by primary key IOTs behave just like regular tables as far as your application is concerned; you use SQL to access them as normal IOTs are especially useful for information retrieval, spatial, and OLAP applications We discussed IOTs in some detail in the previous chapter B*Tree cluster indexes: These are a slight variation of conventional B*Tree indexes They are used to index the cluster keys (see the section Index Clustered Tables in 10) and will not be discussed again in this chapter Rather than having a key that points to a row, as for a conventional B*Tree, a B*Tree cluster has a cluster key that points to the block that contains the rows related to that cluster key. word data matrix font,asp.net barcode control,birt upc-a,java barcode scanner library,how to generate and print barcode in c# windows application,crystal reports data matrix barcode qr code generator in asp.net c# How To Generate QR Code Using ASP .

The VB .NET Implementation of the Receiver Class Public Class Receiver Private _stopRequested As Boolean Private _socket As Socket Public Sub New(ByVal theSocket As Socket) _socket = theSocket End Sub Public Sub [Stop]() _stopRequested = True End Sub Public Sub Run() _stopRequested = False While Not _stopRequested CheckForIncomingTraffic() End While End Sub Sub CheckForIncomingTraffic() If _socket.Available = 0 Then FireIdle() Else FireResponse(_socket) End If End Sub Public Event OnResponse(ByVal theSocket As Socket) Sub FireResponse(ByVal theSocket As Socket) RaiseEvent OnResponse(theSocket) End Sub Public Event OnIdle() Sub FireIdle() RaiseEvent OnIdle() End Sub End Class Receiver runs a loop in its Run method. To avoid using too much CPU time, the class idles after each iteration through the loop. The idle is accomplished by firing an event, which the Coordinator handles by putting the thread to sleep for a while. As soon as incoming data is detected on the receiver s socket, an event is fired. The Coordinator handles the event with the method HandleResponse. To read the response, the Coordinator creates an HttpResponse object and calls its Get method. Listing 12-13 and Listing 12-14 show C# and VB .NET implementations of HttpResponse. qr code generator in asp.net c# How To Generate QR Code Using ASP . NET - C# Corner 24 Nov 2018 ...

However, the CancelRate for All is incorrect. It s a sum of the CancelRate for the individual regions, instead of a calculation of the CancelRate, based on the All totals. You d prefer to have the CancelRate for All be calculated like the CancelRate for the individual regions. Descending indexes: Descending indexes allow for data to be sorted from big to small (descending) instead of small to big (ascending) in the index structure We ll take a look at why that might be important and how they work Reverse key indexes: These are B*Tree indexes whereby the bytes in the key are reversed Reverse key indexes can be used to obtain a more even distribution of index entries throughout an index that is populated with increasing values For example, if I am using a sequence to generate a primary key, the sequence will generate values like 987500, 987501, 987502, and so on These values are sequential, so if I were using a conventional B*Tree index, they would all tend to go the same right-hand-side block, thus increasing contention for that block With a reverse key index, Oracle will logically index 205789, 105789, 005789, and so on instead. Listing 12-13. The C# Implementation of the HttpResponse Class public class HttpResponse { Socket socket; HttpResponseHeader header; public HttpResponseHeader Header { get {return header;} } byte[] body; public byte[] Body { get {return body;} } public int SequenceNumber { get {return header.SequenceNumber;} } public HttpResponse(Socket theSocket) { socket = theSocket; } public void Get() { NetworkStream networkStream = new NetworkStream(socket); // read the response header header = new HttpResponseHeader(networkStream); // read the response body (if any) if (header.ContentLength == 0) return; byte[] buffer = new byte[header.ContentLength]; networkStream.Read(buffer, 0, buffer.Length); body = buffer; } } asp.net vb qr code ASP .
