XPCOMAs a component technology implemented by Microsoft, the component development technology COM in Linux plays an important role in the Windows platform and can be seen in module reuse and cross-language communication. But today I want to introduce the com implementation in Linux ---- XPCOM, which is the basic technology used in the Mozilla Browser project. We can use C ++ to create the XPCOM component, i

Here's the question: how deep is the. NET Framework related to com/com+.

32-bit COM components developed by. NET and C ++ are often included in a large application.ProgramGroup. However, after being deployed to a Windows 64-bit system, the error "retrieving CLSID 80040154 of com-class factory components" may occur.
The solution is as follows:
In the. NET project, right-click the project and choose Properties to open the project property configuration page:

Last night, I was so tired that I was so bored that I was always confused when I got the result for three or more nights: I was unable to create objects by calling C # exported class libraries using vc6, And I used VB to do the same. Re-examine the interface definition and consciously regulate it. How can this problem be solved?Looking at the framework design guide, I suddenly found the following sentence:
If there is no common default constructor (constructor without parameters), the

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

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
Like to use. NET objects using COM
is COM technology out of date?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

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.
