n this chapter, you ll learn how the Enterprise Library can facilitate the implementation of domain (business) rules within an application. With Enterprise Library 2.0, you were on your own when figuring out how to implement this kind of functionality, but Enterprise Library 3.0 has a solution to help complete the puzzle for you. The Validation Application Block allows you to provide validators for .NET Framework data types. These validators apply specific validation rules to objects and determine whether the objects pass validation. This can be useful in many parts of any application, such as validating a tax identification number entered into a text box or validating data passed into a web service. The Validation Application Block also targets the following technologies: ASP .NET, for validating data in web controls Windows forms, for validating data in windows controls Windows Communication Foundation (WCF), for validating data passed into a WCF service This chapter covers the design of the Validation Application Block, using the built-in validators, and creating a custom validator.

we ll need to push one circle to the left and the other to the right. The collision vector that we calculated in step 2 will be the correct direction for one of the circles, but not the other. However, we know that the directions the circles need to move in will be the polar opposites of each other. That means we can use the xSide and ySide variables (which will be 1 or -1) to correctly invert one of the vectors. //Move _c1 out of the collision _c1.setX = _c1.xPos + (collision_Vx * xSide); _c1.setY = _c1.yPos + (collision_Vy * ySide); //Move _c2 out of the collision _c2.setX = _c2.xPos + (collision_Vx * -xSide); _c2.setY = _c2.yPos + (collision_Vy * -ySide); The orientation of the circles will always be changing, so we can never know which circle s overlap vector to invert. Luckily, the xSide and ySide variables take care of keeping track of that for us automatically. Figure 3-23 shows how the circles new positions are found.

To access the position values, you first need to locate the array in which they re stored, and then the specific x and y values. This is what the syntax looks like: _ positions[containingArray][subArray]; or, if you prefer: _ positions[bigFish][smallFish]; In the context of a loop, it looks like this: _ positions[i][0]; _ positions[i][1]; On the first loop, the preceding code will be read like this: _ positions[position1][969]; _ positions[position1][378]; On the second loop, it will look like this: _ positions[position2][1298]; _ positions[position2][1045]; Neat, huh This is called a two-dimensional array. It s an array that contains other arrays. There s a short form for creating two-dimensional arrays. You can create both the containing array and the subarrays in one step, like this: private var _orbPositions:Array =[[969,378],[1298,1045],[2109,1696],[2301,700]]; But it s much easier to read if you format it like this: private var _orbPositions:Array = [ [969,378], [1298,1045], [2109,1696], [2301,700] ]; Can you see why it s called a two-dimensional array When you format it in this way, you can clearly see that the data creates a grid. It has height and width, just like a two-dimensional shape. This is conceptually an extremely important thing to understand. If you can see the shape of this data grid, it makes certain calculations in your games much easier for you to understand. You ll see how useful this is in s 8 and 9, where two-dimensional arrays actually become the visual representation of the game level. But even in this example, a quick glance at that array reveals where the pairs of x and y values are. You could also think of them as two columns. This makes it very easy to edit and debug the data.

The Validation Application Block provides the functionality necessary to validate .NET Framework data types. The data type validation is performed by a series of classes called validators.

There is a disjoint in that the client has two parallel tasks running, and this means the logic used to send the structure is not the logic used to receive the result structure In a nutshell, the left hand has no idea what the right hand is doing The problem relates to two queries running on behalf of a single client When the client receives a E B V N result, how does the client know which query the result belongs to Putting this practically, imagine an HTML page with two text boxes Each text box represents an instance of the same task, but different task data Each text box starts the same task, resulting in two task instances executing with different data The problems begin when the client retrieves a result The receiving algorithm does not know which text box a result belongs to.

Two-dimensional arrays offer a great solution to our problem. Figure 5-18 helps you to visualize how they work.

The core component of the Validation Application Block is the Validator class. This class is the base class from which all validators inherit. The Validator class provides functionality for logging the results so the appropriate action(s) can take place. The Validator class diagram is shown in Figure 12-1.
