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

in the "Big talk design mode C + + version-abstract Factory mode", we save the world attempted, leaving little regret, in this article we will give a solution--com component technology, but also pull the factory model in the application of COM component technology.The root cause of the Factory mode violation of the open-closed principle is that the object generation cannot be controlled by the data outside

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

People familiar with object-oriented programming and network programming must be familiarActiveX,OleAndCOM/DCOMThese concepts are not unfamiliar, but many people are still vague about the relationship between them. In the relationship between them, we should first clarify the components (Component) And object (Object. A component is a reusable module that consists of a set of processing processes, data encapsulation, and user interfaces (Rules object). The component looks like an object, but d

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 programming In-process COM servers (in-process COM server) In-process COM server (in-process COM server) has been introduced briefly before, here, only some need to understand, understand the knowledge points, and then programming may be better; in-process servers are

the object-oriented idea is difficult to adapt to this distributed software model, so the componentized Program design idea has developed rapidly. According to the idea of componentized programming, complex applications are designed into small, single-functional component modules that can run on the same machine, it can also run on different machines. In order to implement such an application, some extremely detailed specifications are required between the build program and the build program.

COM (Component Object Model, Component Object Model) is a binary and network standard created by Microsoft. It is also a component standard that Microsoft has vigorously promoted and widely recognized. In the com standard, the COM object is well encapsulated, and the customer cannot access the implementation details of the object. The only access channel provided

COM component program: module, which can be a dynamic connection library (DLL) executable program (exe), called in-process component) External process component (out-of-process component ).
