The COM component has three basic interface classes: iunknown, iclassfactory, and idispatch.The COM specification specifies that all components and interfaces must be inherited from iunknown. iunknown contains three functions: QueryInterface, addref, and release. These three functions are extremely important, and their order cannot be changed. QueryInterface is used to query other interfaces implemented by
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:

What kind of software products do users need? This is a multiple-choice, but efficient, robust is sure to be selected. What does a software developer do to satisfy a user's needs? You must ensure that the upgrade application does not break backward compatibility with previous versions. You must extend the system service without relying on a specific operating system. Object-oriented programming is clearly a revolutionary change. Using object-oriented design method, we can easily abstract the pro
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

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

JavaScript would make copies of these variables and pass them by value when calling methods then take By-reference parameteRs. Thus, you cann
