In the previous chapters we have seen several run-time features that COM + provides that simplify the development of distributed components that can be used to create scalable, maintainable ASP applications. MTS introduced the transaction model first, and its design simplifies the development of component-based Distributed transaction processing system. As an inheritor of MTS, COM + enhances and exp

Perhaps this is a domestic difficult to see the article about Visual FoxPro and

COM component objects are completely different from. NET class objects, but to make a COM client call a. NET object like a COM component, the. NET program

The object-oriented idea is difficult to adapt to this distributed software model, so the idea of componentized programming 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. On
first, the basic knowledge of COM components introduction:
1, what is COM
COM is a Microsoft set up a component of the specification, the purpose is to achieve the reuse of components, whether you are in C, DELPHI, VB what language to write, as long as the observance of this specification is COM components, can be inv
. NET technology is the next-generation platform technology that Microsoft vigorously promotes. Since the formal release of. NET Technical Architecture Beta2, this technology has gradually become mature and stable. According to Microsoft's platform system occupancy rate, we can easily imagine that in the next year or two. NET technology is bound to become a mainstream technology platform, and the most important premise for a new technology platform to develop rapidly is: he will not abandon the

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? Ensure that the backward compatibility with previous versions is not damaged during application upgrade. System services must be extended without a specific operating system. Object-orientedProgramDesign is obviously a revolution

is COM technology out of date?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
". NET support COM? "
"How do COM + and MTS exist on. NET?" "
". What is the difference between a net component and a COM component? "
COM + is still present in. NET, and if the application does need to use COM + and MTS features, then you can choose the appropriate techn
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
