I accidentally deleted an important piece of data the day before yesterday. I downloaded n more software on the Internet for a long time, but it was ineffective. Later, I found this piriform recuva in the software management tool released by a certain company. I used it in the free version, and the effect was good. I can restore it by directory. Supports shallow scanning and deep scanning. It is not easy to use words to describe it. (Figure 1) (

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

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

Yesterday saw the first chapter of "com Essence", "com is a better C + +", feel it is necessary to do some notes, so organized into this article, I believe you deserve to have.The main content of this article is: A class faststring that implements the fast lookup function, which slowly evolves into a COM component after a small requirement. Class Faststring imple

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

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
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
