Incoporate qr codes in vb Scenarios for .NET Remoting

Summary

Note that values of type Map<string,string> are printed interactively as sequences of key/value pairs. Also, a type annotation is required when reading the data back in using readValue, and a runtime type error results if the types of the objects reconstructed from the binary data don t match this type annotation. The .NET Framework provides several other generic serializers that differ in output format and operational characteristics. The most important of these are based around the notion of DataContract serialization: System.Runtime.Serialization.Json.DataContractJsonSerializer: Used for serializing public data objects into the popular JavaScript Object Notation (JSON) format, using formats that aren t specifically tied to particular .NET types but are rather compatible with a range of types System.Runtime.Serialization.DataContractSerializer: Used for serializing public data objects into XML, using formats that aren t specifically tied to particular .NET types but are rather compatible with a range of types System.Runtime.Serialization.NetDataContractSerializer: Used for serializing arbitrary object graphs, including private data and closures, into XML using the same idioms as the other DataContract serializers

This example showed that the SqlException object carries detailed information about every SQL error in its Errors collection.

private void StartCapture(object sender, RoutedEventArgs e) { } private void StopCapture(object sender, RoutedEventArgs e) { } } 5. Now we ll add the logic to the StartCapture delegate. First check to see if there is already a capture source established; if so, we need to stop it. Next, create a new instance of the CaptureSource, then set VideoCaptureDevice to the system default video capture device and AudioCaptureDevice to the default audio capture device. private void StartCapture(object sender, RoutedEventArgs e) { if (source != null) { source.Stop(); } source = new CaptureSource(); source.VideoCaptureDevice = CaptureDeviceConfiguration.GetDefaultVideoCaptureDevice(); source.AudioCaptureDevice = CaptureDeviceConfiguration.GetDefaultAudioCaptureDevice(); } 6. With the capture devices set, we now need to create a VideoBrush, which will be used to fill our Rectangle control. Set the source of the VideoBrush to the capture source and set the Fill property to the VideoBrush. private void StartCapture(object sender, RoutedEventArgs e) { if (source != null) { source.Stop(); } source = new CaptureSource(); source.VideoCaptureDevice = CaptureDeviceConfiguration.GetDefaultVideoCaptureDevice(); source.AudioCaptureDevice = CaptureDeviceConfiguration.GetDefaultAudioCaptureDevice();

Click the Create button and you will see Figure 3 41. Now you are ready to deploy the WCF application that you created in the foregoing section. Notice here that you will be able to deploy first to staging to test your WCF and then deploy to production. This is a very nice feature in that you will be able to test the application running against a real cloud-based service without first deploying to production.

You retrieved all the rows in the result set by calling the data reader s Read method, which returns true if there are more rows and false otherwise. Note that the data reader is positioned immediately before the first row prior to the first call to Read.

To run the prefix.sh script on Windows, use a program such as Cygwin (http://www.cygwin.com/). Tip
