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
made Microsoft decide to let COM workgroups add performance equivalent to VBX on an automated basis. The result of this development process is the OCX control (a special Automation DLL server) that uses COM technology to support all the features of the VBX control, and it is upgraded to a 32-bit control from this point. Unfortunately, the advent of the Internet and Java has enabled them to be re-engineered
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
This article provides a programming guide to the programmers who just contacted COM, explaining the inside of the COM server and how to write your own interface in C + +.

languages in the world, there will be no idispatch. :-) We know that the COM component is a C ++ class and uses a virtual function table to call functions. For VC, there is no problem. This was originally designed for C ++, in the past, VB did not work. Now VB can use pointers, or vtable to call functions. VJ also works, but some languages still do not work, that is, the script language, typical examples include VBScript and JavaScript. The reason is

normal use, not NULL. The internal object implements two IUnknown, respectively, of the delegate IUnknown and the non-delegate IUnknown (delegating unknown and nondelgating unknown). IUnknown that are implemented in the usual way are IUnknown, and the delegate IUnknown has different behaviors in different situations: when the object is used normally, the delegate IUnknown passes the call to the delegate IUnknown of the object, and when the object is
program can normally call the function in the DLL. This information is also the function export information. There are many ways to generate the exported information. You can use define XXX extern "C" _ declspec (dllexport) to generate the information. For details about this method, see Windows core programming (fifth edition) ), but the COM component generally does not use this method. Another method is to write the def file and clearly specify the

If you have never touched the COM object, you will find the interface really troublesome. You may have the idea of "It is better to define a class directly for convenience.Indeed, interfaces without com encapsulation are really

In addition, the load balancing feature of COM + applications does not need to be supported by coding, both client programs and component programs can be implemented in the usual
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
