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

Software reuse is the goal pursued by the industry. People always hope to "Assemble" applications as they build blocks, and component objects act as building blocks. The so-called component object is actually a predefined service or interface that can complete certain functions. The question is, how do these component objects coexist with applications and other component objects and communicate and interact with each other? So what should I do? Standards, allowing these component objects to work
is COM technology out of date? That's not true either. Technically, it is true that COM usage is declining, but intellectually, the idea of COM's interface-oriented is being carried forward by Java and. Net. So we still need to deal with COM. It depends on the area of your work. Although now Microsoft's platform is slowly toward. Net migration,
The. NET Framework reusable software is not a new concept. For eight of years, people have been using various forms of Component object models (COM). It turns out that it is the most successful reusable software model. COM introduces the concept of "component"-a reusable block of code that can be combined to combine the functions of multiple independent functions to extend to applications such as Microsoft

Advanced com projects often need to pass objects across threads to call these object methods in different threads to stimulate their events. The following article is intended for junior com developers who have basic com knowledge (such as understanding the iunkown
The T-SQL programming language of SQL Server is powerful in data storage and recovery, but is less functional in terms of interaction with systems outside of the SQL Server database. However, we can overcome this limitation with SQL Server's built-in COM automation environment, which enables users to automate COM objects in stored procedures.

In my daily work, I have seen many COM codes written by different developers. I was amazed by the many creative ways of working with COM, and some of the clever code that made COM work might not even have occurred to Microsoft. Also, seeing some mistakes repeated again and again made me frustrated. Many of these errors are related to thread and security, and this

One of the purposes of the. NET Remoting is to provide a rich, distributed environment in which developers can combine and match serialization protocols (formatters) and network protocols (channels) in this environment.

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

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 problem starts with this: I need to write a COM + to connect to different databases. Some friends might say that you should build a COM + for each database, but not in my system. We are doing an education-assisted system, the user is a school (including school teachers, students, parents), we build a database for each school, these databases are the same structure. Of course, we also have a management d
