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

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.

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.
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. This standard allows communication between any two components without considering whether the operating env
Com -- Component Object Model (Component Object Model) is a set of software development methods and specifications proposed by Microsoft. It also represents a software development idea, that is, the idea of component-oriented programming.COM programming ideology-component-oriented programming ideology (COP)
As we all know, the transition from process-oriented programming to object-oriented programming is realized from C to C ++. The emergence of
1, the implementation of COM and operating system platform is closely related
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
All good programmers will do their best to make the program they write more reusable, because it allows you to quickly write more robust and upgradeable programs.There are two choices to make code reuse:1. White box: The simplest one is to copy your tablet to another file.2. Black box: It consists of connecting the compiled pieces of the program. So the compiled black box class library that the client can invoke is called a component.. NET also provides developers with a way to build and expand

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,

COM objects are similar to the concepts of classes in C + + language, each instance of a class represents a COM object, it also includes attributes (i.e., state) and methods (i.e., operations), and States reflect the existence of objects, the method being interfaces.
