Implement DataMatrix in Objective-C INDEXES

CHAPTER 7 USING THE ASP.NET AJAX CONTROL TOOLKIT (PART 1)

Each data item is separated by a comma, and each line is separated by a carriage return. To make this data easier to consume by the data retrieval and business logic tiers, a web service consumes this HTTP service and exposes it as a structured DataTable. You ll see this in the next section.

Let s create a Hello World (or Hi yo Silver) application: 1. 2. Open the file ~\MainPage.xaml. By default, MainPage.xaml will contain a Grid tag like the following: <Grid x:Name="LayoutRoot" Background="White"> </Grid> Silverlight and WPF allow you to nest tags inside one another. Enter the following between the Grid tags: <TextBlock>Hi yo Silver</TextBlock> You should now have something like the following: <UserControl x:Class="14.HelloSilverlight.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="400"> <Grid x:Name="LayoutRoot" Background="White"> <TextBlock>Hi yo Silver</TextBlock> </Grid> </UserControl> 3. Press F5 to run your application. You should see the text Hi yo Silver displayed on a page.

The statistics type is one of the possible ways for telling the CBO the truth about the selectivity and the cost of a function s execution during SQL statement processing. Unfortunately, developing a statistics type is very time-consuming. Fortunately, we have a shortcut of simply specifying default selectivity and cost values.

float up = +f; // use the unary minus operator float um = -f; // print out the results Console.WriteLine("Unary plus result: {0}", up); Console.WriteLine("Unary minus result: {0}", um); // wait for input before exiting Console.WriteLine("Press enter to finish"); Console.ReadLine(); } } Compiling and running the code in Listing 5-16 produces the following results: Unary plus result: 26.765 Unary minus result: -26.765 Press enter to finish The prefix and postfix increment and decrement operators are used widely, especially in for loops; see 4 for more information about for loops. These operators are a convenience that allow you to simplify your code. We start with a numeric type; let s use an int:

With your vertices defined, you re ready to render your triangles. The second part of this chapter explains how you can code your own HLSL effects, but in the first recipes you ll simply use the BasicEffect. The BasicEffect is a predefined effect that can be used to render stuff using basic lighting effects. Make sure you have one BasicEffect variable you recycle each frame, because it is too costly to create a new BasicEffect object each frame. Add this variable to the top of your class: BasicEffect basicEffect; And instantiate it in your LoadContent method: basicEffect = new BasicEffect(device, null); The following settings will render your 3D scene lit from one directional light, like the sun: basicEffect.World = Matrix.Identity; basicEffect.View = fpsCam.ViewMatrix; basicEffect.Projection = fpsCam.ProjectionMatrix; basicEffect.Texture = myTexture; basicEffect.TextureEnabled = true; basicEffect.LightingEnabled = true; basicEffect.AmbientLightColor = new Vector3(0.1f, 0.1f, 0.1f); basicEffect.PreferPerPixelLighting = true; basicEffect.DirectionalLight0.Direction = new Vector3(1, -1, 0); basicEffect.DirectionalLight0.DiffuseColor = Color.White.ToVector3(); basicEffect.DirectionalLight0.Enabled = true; basicEffect.DirectionalLight1.Enabled = false; basicEffect.DirectionalLight2.Enabled = false; The upper part sets the World, View, and Projection matrices, which are required to transform your 3D scene to your 2D screen. See recipes 2-1 and 4-2 for more information on them. Because you have stored texture coordinates inside each vertex, you can pass a texture to your graphics card and enable texturing so your triangles will get the colors from the image. See recipe 5-2 for more information on textures.

Be careful it's as easy to delete an icon as it is to move it, but when you delete an icon on the iPod touch, you are actually deleting the program it represents. This means you won t be able to use the program again without reinstalling it or downloading it again. Depending on your Application Sync settings in iTunes, the program may still reside in your Applications folder in iTunes. In that case, you would be able to easily reinstall the deleted app if you wanted to by checking that application in the list of apps to sync in iTunes. If not, you can always download it again onto your device, from the same account, at no charge As Figure 6 3 shows, the deleting process is similar to the moving process. Touch and hold any icon to initiate deleting. Just as before, touching and holding makes the icons shake and allows you to move or delete them. NOTE: You can delete only programs you have downloaded to your iPod touch; the preinstalled icons and their associated programs can t be deleted. You can tell which programs can be deleted because the icons contain a small black x in the upper left corner. Just tap the x on the icon you d like to delete. You'll be prompted to either delete, or cancel the delete request. If you select Delete, the icon and its related app are removed from your iPod touch.
