Com is the abbreviation of Component Object Model. What kind of software products do users need? This is a multi-choice question, but it is highly efficient and robust. How can a software developer meet users' needs? Upgrade is requiredThe application does not compromise the backward compatibility with previous versions. System services must be extended without a specific operating system. Object-orientedProgramDesign is obviously a revolutionary ch

Say in front COM This word we listen to a lot of, it is what it is, whether it has practical value. If it works for us, then how to write COM components in Visual FoxPro. The author will stand on the position of Visual FoxPro developers, with you to discuss the above issues, I hope to help you. Perhaps this is a domestic difficult to see the article about Visual FoxPro and

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

This time I was thinking about how to use a small program with COM components. I suddenly remembered why I used com during the last interview, instead of using a common DLL? After checking it on Google, many people also asked the same question: using COM to write a program is more troublesome than using a common DLL, but it brings a lot of benefits, especially wh

COM (formerly known as OLE) represents Microsoft's "Component Object Model" (Component object models), which is the basis for all ActiveX technologies, including ActiveX controls, automation, and ActiveX documents. But COM also contains more stuff. It is a special specification that the component objects that it develops can be "interoperable" through the specialized features of the operating system. In pra

From: http://blog.163.com/junby2004@126/blog/static/9714233120091105308843/ People familiar with object-oriented programming and network programming must be familiar with ActiveX, Ole, and COM/DCOM concepts, but the relationship between them is still vague to many. The difference between components and objects should be clarified first. A component is a reusable module that consists of a set of processing

Thursday, March 15,200 1 By ish Singh Introduction: Com is sometimes referenced as common object model but Microsoft officially callit Component Object Model. microsoft also developed DCOM as an extension of COM. DCOM was designed with Distributed Computing in perspective. CORBA stands for Common Object Request Broker Architecture and developed by Object Management Group (OMG ).

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: Installed on the same machine The COM component used is of different versions. In this way, if you use a common registered

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.
