the object-oriented idea is difficult to adapt to this distributed software model, so the componentized Program design idea has developed rapidly. According to the idea of componentized programming, complex applications are designed into small, single-functional component modules that can run on the same machine, it can also run on different machines. In order to implement such an application, some extremely detailed specifications are required between the build program and the build program.

One of the purposes of the. NET Remoting is to provide a rich, distributed environment in which developers can combine and match serialization protocols (formatters) and network protocols (channels) in this environment. COM + WEB Services in the. NET Framework version 1.0 support only one formatter (SOAP) and a channel (HTTP). This is not to say that other ch

COM (formerly known as OLE) represents Microsoft's "Component Object Model" (Component object models), which is the basis for all ActiveX technologies, including ActiveX controls, automation, and ActiveX documents. But COM also contains more stuff. It is a special specification that the component objects that it develops can be "interoperable" through the specialized features of the operating system. In pra

People familiar with object-oriented programming and network programming must be familiar with ActiveX, Ole, and COM/DCOM concepts, but the relationship between them is still vague to many.
The difference between components and objects should be clarified first.
A component is a reusable module that consists of a set of processing

Introduction:
Com is sometimes referenced as common object model but Microsoft officially callit Component Object Model. microsoft also developed DCOM as an extension of COM. DCOM was designed with Distributed Computing in perspective. CORBA stands for Common Object Request Broker Architecture and developed by Object Management Group (OMG ).
Chapter 4 components
1. com, the component object model, is a standard on how to build components and how to build applications through components.2. Advantages of components: applications can develop and change over time, custom applications, Component Libraries, and distributed components.3. Requirements for components: components must be dynamically connected; internal implementation details must be hidden.4. the
is COM technology out of date? That's not true either. Technically, it is true that COM usage is declining, but intellectually, the idea of COM's interface-oriented is being carried forward by Java and. Net. So we still need to deal with COM. It depends on the area of your work. Although now Microsoft's platform is slowly toward. Net migration,
The. NET Framework reusable software is not a new concept. For eight of years, people have been using various forms of Component object models (COM). It turns out that it is the most successful reusable software model. COM introduces the concept of "component"-a reusable block of code that can be combined to combine the functions of multiple independent functions to extend to applications such as Microsoft

The COM component has three basic interface classes: iunknown, iclassfactory, and idispatch.The COM specification specifies that all components and interfaces must be inherited from iunknown. iunknown contains three functions: QueryInterface, addref, and release. These three functions are extremely important, and their order cannot be changed. QueryInterface is used to query other interfaces implemented by

The T-SQL programming language of SQL Server is powerful in data storage and recovery, but is less functional in terms of interaction with systems outside of the SQL Server database. However, we can overcome this limitation with SQL Server's built-in COM automation environment, which enables users to automate COM objects in stored procedures.
With 7 extended stored procedures in SQL Server 7.0 and SQL Serve
