The value validators are designed to assess the value of an object and determine if the object s value is valid based on the validator s rules and parameters. The three types of value validators are NotNullValidator, DomainValidator, and ContainsCharactersValidator. NotNullValidator The NotNullValidator class tests to see whether the value of a particular object is null. The constructor has four overloaded versions that allow for message templates and the option to negate the results of the test. Figure 12-15 shows a class diagram with these overloaded constructors. zxing c# create qr code C# QR Code Generator Tutorial | Iron Barcode - Iron Software

You doesn't fully initialize the BarcodeWriter. You have to set the barcode format. Try the following code snippet: IBarcodeWriter writer = new ... So far, so good, but there are a few more details we need to figure out before we have a complete working system. We re going to look at how to project the shapes onto each axis in detail in the pages ahead, as this varies in complexity depending on the kinds of polygons you re using. Here, I ll show you how to determine whether the projections are overlapping, and how to calculate the amount of overlap. We need a vector that runs between the centers of both squares. This is the distance vector. The distance vector also needs to be projected onto each axis, as shown in Figure 4-5. The NotNullValidator class also has a corresponding class to support attribute-based validation, called NotNullValidatorAttribute. Figure 12-16 shows its public constructors. zxing c# create qr code QR Code Generator In ASP.NET Core Using ZXING .NET - C# Corner

NET MVC applications. else if( reference == "2" && valIdentifier == transactionIdentifier2Counter) { return true; } else { return false; } } In the implementation of IsActiveTransactionIdentifier, the parameter transactionIdentifier is from the result, where an example would be 1_101 The transaction identifier parameter is encoded and needs to be separated into two pieces; the first piece is the destination span element, and the second piece is the transaction identifier (transactionIdentifier1Counter or transactionIdentifier2Counter) The two pieces are verified, and if the destination span element references an active transaction identifier, a true is returned; otherwise, a false is returned Returning true allows a result to be processed If the result is processed, the destination of the result needs to be extracted by using the function GetResultField, which is implemented as follows: function GetResultField( transactionIdentifier) { var reference = transactionIdentifier. Figure 4-5. Plot a distance vector between the shapes and project it onto the x and y axes. Use the distance vector s projections like a measuring stick to measure the distance between the centers of the projections of the squares on each axis, as illustrated in Figure 4-6. zxing qr code encoder example c# How to Generate QR Code in C# Windows Application Tutorial

NotNullValidatorAttribute class diagram Using the constructor with the negated parameter will allow you to test to see if the parameter is null, as opposed to being not null. Listing 12-7 shows an example of this usage of NotNullValidator. Listing 12-7. Using NotNullValidator to Test for Nulls public class MyClass { private string m_MyValue; [NotNullValidator(true)] public string MyValue { get { return m_MyValue; } set { m_MyValue = value; } } } Figure 4-6. Measure the distance between the projections of the shapes to find out whether they overlap. Follow these steps to find out whether there s any overlap: charAt( 0); if( reference == "1") { return "result1"; } EBVN else if( reference == "2") { return "result2"; } throw new Error("Invalid transaction identifier value"); } In the implementation of GetResultField, the code used to extract the field reference is identical to the code used in the function IsActiveTransactionIdentifier, and this is done for illustration purposes only The decision block tests to see if the variable reference has the value 1 or 2, and if so returns the appropriate HTML identifier If the variable reference is neither 1 or 2, an exception is thrown to indicate an incorrectly formatted transactionIdentifier parameter Earlier it was mentioned that on the client side there is no reusable code because the implementation of the pattern is specific to the problem being solved This is not entirely correct, because some pieces of the HTML client code could have been combined into a small library. DomainValidator The DomainValidator class checks to see that a value is contained within a specific set of values. For instance, you could check to see if an integer is 1, 5, 7, or 11, or that a string is either "yes" or "no". This class can also be used for determining equality by simply specifying one value to compare against. Figure 12-17 shows the available public constructors. 1. Add the projections of the shapes together, and divide that number in half. In Figure 4-5, zxing c# qr code example How To Generate QR Code Using ASP . NET
