Software methods and COM Support Based on Component Reuse Zhang YuComputer College, Huazhong University of Science and Technology SummaryAs a hot topic of research, component models have emerged in an endless stream in recent years. For the interoperability between them, a public component must be available.The underlying framework analyzes various practical factors. com is a feasible choice. This article d

COM component program: module, which can be a dynamic connection library (DLL) executable program (exe), called in-process component) External process component (out-of-process component ). COM Object: it is based on binary executable code. Therefore, COM objects are language-independent. This feature makes it possible to interact with Component Objects develop

PHP can operate COM and DCOM objects on Win32 platforms. 1. I have created a DLL to calculate something. Is there any way to run this DLL in PHP? 2. What does 'unsupported variant type: xxxx (0 XXXXX) 'mean? 3. Is it possible to operate on visual objects in PHP? 4. Can I store COM objects in the session? 5. How can I capture com errors? 6. How can I generate DLL

The previous article said how to design a pseudo-com, now let's see how the real COM library is modular.First of all, the previous section of our implementation of pseudo-com there is nothing to make you uncomfortable place? Yes, I believe a lot of people are very uncomfortable with the need to load DLLs and export interfaces themselves , Microsoft is also very u

　　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. [Guid ("0bb13346-7e9d-4aba-9ff2-862e0105489a")] public interface Imyservice { Defines an interface method or attribute, each of which has a DispID property for use by VBScript, etc. [DispId (1)] void Method1 (args

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,

Differences: (1) Static Connection Library as the targetCodeIs linked (2) the dynamic Connection Library and the target code are two parts. (3) The COM component is called by registering the location and interface of the dynamic library in the registry. Advantages and disadvantages: (1) Static disadvantage: Make the targetProgramIncreased volume, not flexible(2) Advantages of Dynamic Link Library: to modularize the program, as long as the in

What is a COM component?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-Oriented Programming is obviously a revolutionary change. Using an object-oriented

Computer" security settings here, by modifying the registry to open this option, you can give us more choices when dealing with ActiveX controls, and have a greater impact on local computer security.Here's how to do this: open "Run" from the Start menu, enter Regedit.exe in the "Run" dialog box, open the Registry Editor, and click the "" "number in the previous page to expand to: Hkey_curre-nt_user\software\microsoft \windows\currentversion\internetsettings\zones\0, find the DWORD value "flags"

Overview] This article starts with a basic concept, and clearly demonstrates COM in terms of COM interfaces, type libraries, GUIDs, and so on. At the same time, this article also introduces the creation of COM objects, what is MTS, how to use MTS to manage COM objects, his advantages and programmatic implementation, an

problem of COM Object running under CLR. First, compare COM Object and. Net object.1. The customer of COM object must manage the life time of COM object by themselves;. Net object is managed by CLR (GC)2. The customer of COM ojbect calls QueryInterface to query whether

First, I declare that I am not a master of COM/ATL. Although I have been in contact with them for four years, I have not been able to conduct in-depth research and use them extensively for some reasons at work. However, it is a bit difficult to look back at their painful experiences. Here, I would like to share with you how to learn them, so as to reduce the detours for later users. I personally think it is not easy to learn

Mutual operations between the. NET component and the COM component // (convert) . 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 share, we can easily imagine that in the next year or two. NET technology is bound to become a mainstream technology pl

If you change the SingleCall property of the wellknown element to Singleton, the activa

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. The purpose of COM is to
