COM objects are encapsulated entities that provide services to users. This should be similar to the Class Object in C ++. But sometimes the COM object is treated as the class that provides services. The COM Object also encapsulates the data and provides interfaces. But there are some differences with the class. The data in the class can be declared as public, and

-registration. Generally, the com library is implemented by the operating system, so programmers do not have to worry about its implementation details. [Note] DirectX technology To develop games on Windows, you must understand two heavyweight game APIs: DirectX and OpenGL. DirectX is an API developed by Microsoft to optimize game production. DirectX consists o

This digest from: http://www.job168.com/info/read_100394.htmlMany of Microsoft's technologies, such as OLE, ActiveX, and DirectX, are built on COM technology. Microsoft itself also uses a lot of COM components to customize their applications and operating systems. So, what is COM?The so-called

This article provides a programming guide to the programmers who just contacted COM, explaining the inside of the COM server and how to write your own interface in C + +. Following the introduction of previous COM programming, this article discusses the content of COM servers, explains the steps and knowledge needed t

Difference Author: Sunwen translation All the best programmers do their best to make their written programs more reusable, because it allows you to quickly write more robust and scalable programs. There are two choices to make code reusable: 1. White box: The simplest one is to copy your program to another file. 2. Black box: It involves connecting a compiled piece of the program. So the compiled black box class library that the client can invoke is called a component. . NET also provides dev

Part of this section requires the reader to be familiar with the message invocation principle of COM, and the principle of this is as shown in Mr. Yang's column. Previous content: COM Server--> COM client ... COM server-->. NET Client 1, P/invoke 2, COM Interop (conten

Just now I went online and found another beautiful article with all the images. That's great... What theoretical knowledge of COM must be mastered when using VC for COM programming? I have seen a lot of people learn about com. After reading a book, I feel that I have a better understanding of the principles of COM, but

From Com to com -- Hou Jie Abstract: This document introduces the basic concepts of C ++ object model and component object model, and introducesFour Books: 1. Inside the C ++ Object Model 2.

felt like I was playing jigsaw puzzles. Beginning with a programming language, the system eventually includes C, C + +, Java, SDK, MFC, VxD, Win32 OS, multithreading, C + + STL, Internet Protocol .... I looked at this puzzle and felt that all the changes in the world were almost in my hands. No matter what new things are being exhibited to the language, what application the framework, or what the new driver model, the new protocol, I feel that because I have mastered the basic knowledge, I have

1, the object-oriented system of the three most basic characteristics Encapsulation, polymorphism, reusability. 2, COM characteristics of the overview The encapsulation characteristics of COM objects are very thorough, all object state information must be accessible through an interface, while COM polymorphism is fully represented by the interface, and

Delphi object-oriented Learning Article 7: COMAuthor: banhamtHttp://www.cnpack.org(Please indicate the source and keep it complete)In the previous article, we introduced interfaces. If you have never touched the COM object, you will find the interface really troublesome. You may have the idea of "It is better to define a class directly for convenience.Indeed, interfaces without com encapsulation are really
