All outstanding programmers will do their best to make their programs more reusable, because it allows you to quickly write more robust and scalable programs.
There are two options for code reuse:
1. white box: the simplest one is to copy your program to another file.2. Black Box: it includes connecting compiled program slices. Therefore, the compiled black box class library that can be called by the client is called a component.

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

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

I. In-process components and out-of-process Components
As mentioned above, COM components support both in-process components and out-of-process components. The advantage of in-process components is fast and convenient. However, if any component crashes, the main process will crash. Components outside the process are slow but stable. If a component crashes somewhere, at most there is no result and the main process will not crash (for example, if the

Because COM originated in the Microsoft Windows platform, the COM implementation part (that is, the COM library) uses some of the features of the Windows system directly, such as the system registry, the dynamic Connection library, and so on

is MTS and COM
First fewArticleSummary of the Application of COM. COM + cannot be mentioned for applications involving COM.
COM + is no longer limited to the COM component technology. It focuses more on the design and implementation of distributed network applications.
For beginners, COM is not a very clear definition. It represents both a component specification and an implementation. In short, COM is a component model at the language layer, because different development environments often need to cooperate with each other to complete a certain function, thus promoting the emergence of COM.
Through the previous study and practice, we have learned how com is and how to call COM components.
To sum up, COM is the component object model, which means that the COM Object and COM class are different from the objects and classes in C ++, VB, or Delphi,

What is COM?The so-called COM (Componet Object Model, Component Object Model) is a specification that describes how to establish dynamically changing components. This SPECIFICATION provides a way to ensure interoperability, some binary and network standards that customers and components should follow.
