Some basic knowledge about com Basic knowledge of Component Object ModelComponent-based software development is becoming increasingly popular. Here I will give you some com-related things I have prepared at school for your reference.I. Components(COM) is a new software development technology developed by Microsoft to make software production in the computer indus

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

This article explains the various types of thread models proposed by COM, and explains how the com Runtime Library implements them. The thread model is a mathematical model provided specifically for multithreaded programming.AlgorithmBut it is only an algorithm, not an implementation. This article explains the various types of thread models proposed by COM, and

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

From: http://blog.163.com/junby2004@126/blog/static/9714233120091105308843/ 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

Thursday, March 15,200 1 By ish Singh 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 ).

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

Recently, this registry-free COM technology was used in our work, that is, free registration of COM. The COM component we provide will be used by multiple products, and these products may: Installed on the same machine The COM component used is of different versions. In this way, if you use a common registered

What kind of software products do users need? This is a multiple-choice, but efficient, robust is sure to be selected. What does a software developer do to satisfy a user's needs? You must ensure that the upgrade application does not break backward compatibility with previous versions. You must extend the system service without relying on a specific operating system. Object-oriented programming is clearly a revolutionary change. Using object-oriented design method, we can easily abstract the pro

People who are familiar with object-oriented programming and network programming must not be unfamiliar with the concepts of ActiveX, OLE, and com/dcom, but what is the relationship between them is rather vague for many people.Between the specific descriptions of their relationships, we will first identify the difference between the component (Component) and the object. A component is a reusable module that is a business object (Rules object) that con
