Fractals are one of the diamonds of mathematics. They show the beauty of mathematical structures visually, which allows non-experts to see something that is often hidden by formulas that few really appreciate. The Mandelbrot set is one of the most famous fractals. This section shows how to develop an application to browse this set. The result is shown in Figure 11-7. This application adopts the delegation programming style, subscribing to events rather than using inheritance to override the behavior of a component. This allows you to develop the application interactively using fsi.exe. This is a good example of how effectively you can use F# to develop an application interactively while retaining the performance of a compiled language, which is extremely important in such CPU-intensive tasks as computing the points of the Mandelbrot set. generate barcode crystal reports 2008 using barcode creation for .net vs 2010 crystal report control to generate, create barcodes image in .net vs 2010 crystal report applications. developed BusinessRefinery.com/barcodebarcode .net tutorial use .net framework barcode integrating to produce bar code on .net reference BusinessRefinery.com/ barcodesFigure 3 38.

And before you can take advantage of the location service, you must enable the location service on the phone by going to Settings Location turn on Location Services option. You can detect whether the phone s location service is enabled using the StatusChanged event of GeoCoordinateWatcher, as seen in the following code. GeoCoordinateWatcher geoCoordinateWatcher; geoCoordinateWatcher = new GeoCoordinateWatcher(GeoPositionAccuracy.High); geoCoordinateWatcher.MovementThreshold = 100; // in Meters geoCoordinateWatcher.StatusChanged += (s, e) => { if (e.Status == GeoPositionStatus.Disabled) { MessageBox.Show("Please enable your location service by going to Settings -> Location -> Turn on Location Services option."); } }; Another way to check if the location service is enabled is to use TryStart to see if the GeoCoordinateWatcher can be started. if (!_geoCoordinateWatcher.TryStart(true, TimeSpan.FromSeconds(5))) { MessageBox.Show("Please enable Location Service on the Phone.", "Warning", MessageBoxButton.OK); } Next you have to set DesiredAccuracy and provide MovementThreshold in GeoCoordinateWatcher as seen in the foregoing code. GeoPositionAccuracy.Default will use Wi-Fi or the cell phone towers and depends on the availability of the sources. Windows Phone will automatically choose one to use, and GeoPositionAccuracy.High will use the GPS receiver built into the phone device. MovementThreshold is a very important property to set because MovementThreshold specifies the change in distance in meters before the PositionChanged event notifies the application that new coordinates are available; the lower the value of MovementThreshold, the more accurately the position will be tracked, but you will pay a price in higher power consumption. Microsoft recommends that you set MovementThreshold to at least 20 meters to filter out this noise. In the following sections, you will learn how to use the Windows Phone Location Service by simulating the behavior of the GPS receiver. This simulation allows you to test location-aware applications, like the ones you ll build in this chapter, in the emulator, which lacks a real GPS receiver. to integrate qrcode and qr-code data, size, image with visual basic barcode sdk position BusinessRefinery.com/QR-Codeto connect qrcode and qr-code data, size, image with word barcode sdk assembly BusinessRefinery.com/Quick Response CodeTesting Localization
