To support this concept, child collections implement an internal method named Update(). Child objects within a collection implement internal methods, named Insert(), Update(), and DeleteSelf(), that can be called by the collection during the update process. It is helpful for related root, child, and child collection classes to be placed in the same project (assembly) so that they can use internal scope in this manner. The sequence of events to add, edit, or delete a child object is as follows: 1. The root object s DataPortal_XYZ method calls the child collection s Update() method; the parent object is passed as a parameter so that child objects can use root object property values as needed (such as for foreign key values). 2. The child collection s Update() method loops through all the deleted child objects in the collection, calling each deleted object s DeleteSelf() method. 3. The child collection s Update() method loops through all its active child objects, calling each child object s Insert() or Update() method based on the child object s IsNew property value. 4. At this point, all the child object data has been inserted, updated, or deleted as required. to incoporate qr code jis x 0510 and qr bidimensional barcode data, size, image with microsoft word barcode sdk coding BusinessRefinery.com/Denso QR Bar Codegenerate qr code crystal reports use visual studio .net crystal report qr code iso/iec18004 encoding to deploy qr barcode in .net websites BusinessRefinery.com/QR Code ISO/IEC18004This doesn t sound that hard, until you read the fine print in the documentation and start using the interface and then discover the even finer print that isn t actually in the documentation at all. qr-code image developer with word BusinessRefinery.com/Denso QR Bar Codeqr code 2d barcode size per for .net BusinessRefinery.com/qr-codesName ThreadState

Even the term application has become increasingly blurry due to all the hype around service-oriented architecture (SOA). If you aren t careful, you can end up building applications by combining several applications, which is obviously confusing. When I use the term application in this book, I m referring to a set of code, objects, or components that s considered to be part of a single, logical unit. Even if parts of the application are in different .NET assemblies or installed on different machines, all the code will be viewed as being part of a singular application. pdf 417 barcode reading .net using barcode implement for vs .net control to generate, create pdf417 image in vs .net applications. preview BusinessRefinery.com/barcode pdf417barcode 39 crystal reports vb.net using machine .net crystal report to display uss code 39 in asp.net web,windows application BusinessRefinery.com/3 of 9 barcodeFigure 13-8.

It is used to avoid stepping through code since it prevents the method from being stepped into. Here s an example usage to mark a validation function that is called often. Make sure you use it in a situation like this when you re sure the method isn t the source of any bugs. The following code is the same as in the previous section, but this time, the methods are labeled virtual and override. This produces a result that is very different from that of the previous example. In this version, calling the method through the base class invokes the method in the derived class. class MyBaseClass { virtual public void Print() { Console.WriteLine("This is the base class."); } } class MyDerivedClass : MyBaseClass { override public void Print() { Console.WriteLine("This is the derived class."); } } class Program { static void Main() { MyDerivedClass derived = new MyDerivedClass(); MyBaseClass mybc = (MyBaseClass)derived; derived.Print(); Cast to base class mybc.Print(); } } This code produces the following output: This is the derived class. This is the derived class. Other important information about the virtual and override modifiers is the following: The overriding and overridden methods must have the same accessibility. In other words, the overridden method cannot be, for example, private, and the overriding method public. You cannot override a method that is static or is non-virtual. Methods, properties, and indexers (which I covered in the preceding chapter), and another member type, called events (which I will cover later in the text), can all be declared virtual and override.
