To start off, add ValidationCallHandlerAttribute attributes under the ExceptionCallHandlerAttribute attributes to each of the two methods in the MyClass class, as shown in Listing 13-6. Listing 13-6. Adding ValidationCallHandlerAttribute Attributes using Microsoft.Practices.EnterpriseLibrary.PolicyInjection.CallHandlers; using Microsoft.Practices.EnterpriseLibrary.Validation.Validators; public class MyClass : MarshalByRefObject { //adds two numbers and returns a value [ExceptionCallHandler("MyExceptionPolicy")] [ValidationCallHandler] public int AddTwoNumbers(int firstNumber, int secondNumber) { return firstNumber + secondNumber; } //subtracts two numbers and returns a value [ExceptionCallHandler("MyExceptionPolicy")] [ValidationCallHandler] public int SubtractTwoNumbers(int firstNumber, int secondNumber) { return firstNumber - secondNumber; } } The next task is to add the actual validation attributes to the AddTwoNumbers and SubtractTwoNumbers method s parameters. The validation attributes will ensure the values of each parameter are above 0. Listing 13-7 shows these methods with their parameters decorated with the RangeValidatorAttribute attribute. Listing 13-7. Ensuring Parameter Values Are Above Zero public class MyClass : MarshalByRefObject { //adds two numbers and returns a value [ExceptionCallHandler("MyExceptionPolicy ")] [ValidationCallHandler] public int AddTwoNumbers( zxing.net qr code reader QrCode .

[RangeValidator(typeof(Int32), "0", RangeBoundaryType.Inclusive, "0", RangeBoundaryType.Ignore, MessageTemplate = "Value must be greater than zero." )] int firstNumber, [RangeValidator(typeof(Int32), "0", RangeBoundaryType.Inclusive, "0", RangeBoundaryType.Ignore, MessageTemplate = "Value must be greater than zero." )] int secondNumber) { return firstNumber + secondNumber; } //subtracts two numbers and returns a value [ExceptionCallHandler("MyExceptionPolicy ")] [ValidationCallHandler] public int SubtractTwoNumbers( [RangeValidator(typeof(Int32), "0", RangeBoundaryType.Inclusive, "0", RangeBoundaryType.Ignore, MessageTemplate = "Value must be greater than zero." )] int firstNumber, [RangeValidator(typeof(Int32), "0", RangeBoundaryType.Inclusive, "0", RangeBoundaryType.Ignore, MessageTemplate = "Value must be greater than zero." )] int secondNumber) { return firstNumber - secondNumber; } } Now that the MyClass class contains both exception handling and validation policies defined via attributes, it is time to configure the instrumentation. The Y value increases as you go down and not as you go up, which confused me a bit because it s the opposite of what I learned in math class, but I got used to it pretty quickly To find out how much room you have to paint on, use the getHeight() and getWidth() methods of the Canvas Using the point (0,0) as your top corner and drawing on a rectangle, whose size is given by the getHeight() and getWidth() methods, will automatically ensure that your drawing is correctly placed on the screen If you d like to do a larger drawing according to your own choice of coordinates and then specify which region is shown, you can do it with the clip methods (setClip(), and so on) But, again, I d use the javaxmicroeditionlcdui. Attach the body to the base and block it with two long pins with a stop bush and a 5-long axle in the back. With that said, this doesn t mean that commercial frameworks are all bad. I just urge you to at least evaluate them and determine that they will not hinder your application from a scalability and performance perspective; in addition, you should ensure that they incorporate the current industry best practices. Open source frameworks, or frameworks that provide the source with them, are, in my mind, the better choice. First, most open source frameworks tend to be created and contributed to by developers who listen, respond, and implement the design based on feedback from the development community. Second, the source code is provided with the framework, so if there is something you do not like about a particular framework component, you can change it to your liking. Lastly, these types of frameworks do not try to consider every possible scenario; thus, they typically don t force you to have to consider changing the way you develop your applications. The end result is that they are simple to use and easy to expand upon. Granted, you may have to expand on the open source framework features, but this allows you to gain a deeper knowledge while trying to tackle the specific features you need in order to make your particular implementation of the framework complete. vb.net qr code scanner Barcode Recognition and Generation API for C# and VB .
