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
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

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

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

Translated from https://www.cnblogs.com/manors/archive/2010/05/17/COM_Initialize_STA_MTA.htmlWhen dealing with devices, we often use COM components, such as audio and video devices (microphones, players, cameras, etc.).Before calling any COM component, you must first initialize the COM suite environment, which is called CoInitialize or CoInitializeEx.

Even when you use it, you ignore that he is a COM object. For example: ADO. The only component with the highest call rate is the ability to extend unlimited functionality to your page. However, the ASP itself is an interpretative script that is not functional en

One advantage of component architecture is that applications can evolve over time. In addition, you can also use components to upgrade existing applications more conveniently and flexibly, such as application customization, Component Libraries, and distributed components.
