When I was working on a project a while ago, I encountered the call and use of the COM component. At that time, I had a good research, so I had to get through the intermediate link. Now I wrote it to help you, there are four types:
1. In vs2005, C # compiles a DLL and calls it using C ++.
2. Use vc6.0 to call the COM component written in C # In vs2005
3. Compile COM

3. Create a COM component manually1. From Project Creation to registrationIn this process, we will complete three steps: Create the DLL entry function, define the interface file, and implement the registration function.1

Microsoft has tightly integrated the capabilities of IIS and COM +, which makes it very easy to leverage transactional applications in the process of programming the transaction Web page. There are many different ways to integrate the transaction characteristics of COM + and IIS, including the following:? Transactional ASP.? The ObjectContext in ASP.? Transactional events.Developers can use one or more

Well, I used to ask this question, no one said, or do it yourself better.
Generally, when a COM object is provided, it usually provides a type library in which all the method names, parameter names, property names, and so on of the COM object are defined. All we have to do is ta

Debug COM + in Delphi7
The biggest headache for Developing COM + application systems is how to debug COM + components. Because COM + is executed in the execution environment of COM +, therefore, Delphi programmers cannot directly set the breakpoint of the application server
Use C # to do WinForm programs, long time will inevitably encounter and COM components to deal with the place, how to create COM objects also become a problem we must face. As far as I know, there are several ways to create COM objects:

1. com, the component object model, is a standard on how to build components and how to build applications through components.2. Advantages of components: applications can develop and change over time, custom applications, Component Libraries, and distributed components.3. Requirements for components: components must be dynamically connected; internal implementation details must be hidden.4. the
1. Defining interfaces
COM is called by an external application by throwing an interface, and each interface, component has a GUID, and developing COM components in. NET is no exception.

Defines an interface method or attribute, each of which has a DispID property for use by VBScript, etc.

What is an interface?
When it comes to COM, you have to say interface; In the process of COM development, it can be said that I have been dealing with a variety of interfaces. What's the interface? For COM, an interface is a memory structure that contains an array of function pointers, each containing an address of a function implemented by the component, so for
As the saying goes, the rainbow after the storm, but after the financial turmoil, the rainbow in all walks of life need their own to create. In the economic stability but lack of growth momentum of the situation, each industry is a surprise, want to in the post-crisis era to create a better future for themselves, so as to keep pace with the times to maintain steady growth. In the face of such an economic environment, the domain name industry has also been frequent moves, set off a wave of waves,

The so-called "external mechanism" refers to the process in which an application creates an atl com Object factory. The application does not care whether the COM object is implemented by MFC or by ATL. It always uses API functions such as cocreateinstance to create COM objects through the class factory. In ATL, how does an application call cocreateinstance to the
Navisworks provides three APIs for. NET, COM, and nwcreate. And usually we say that the Navisworks API actually refers to COM or. NET, because the Nwcreate function is more special. Wait for me one by one way:

The COM (ComponentObjectModel) Component Object Model is a way to share binary code across applications and languages. COM can be loaded as a DLL by a local program or called by a remote process in PHP 4.2.0 to 4.2.3 through DCOM. you can use the w32api_register_function function to call an external DLL. open the extended php_w32api.dll in ini.

Component Object Models (Component object model, hereinafter referred to as COM) is a specification of the interface between component objects, and objects that follow COM interface specifications can communicate and interact with each other, even if these objects are made by different vendors, in different languages, Written and built on different versions of Windows and even on different machines.

Say in front
I remember the first time I contacted COM component programming, there is the question: there is no good way to pass the dataset. We know that Visual FoxPro is the most powerful data processing system, and its cursor strong, flexible support is unmatched. Since Visual FoxPro is so powerful at data set processing, COM programming, how to simply in various types of client programs and Visual Fox
Fortunately, we can use COM components to maximize the functionality of the ASP. You know, anything that can be written in a language such as VB,VC and VJ and other programming languages can be applied to the development of your Web site, which is COM (Component Object model). COM can be used to write objects that can be invoked by ASP. When the programming envir
Recently a collaborative 973 project that needs to call someone else's interface. The other side gave a DLL file and function interface description, and then I looked through the traditional generated dll,loadlibrary to find function pointers, through function pointers to call, failed. Later found that the DLL is not a general DLL but a COM interface, need to register AH and so on.
