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
The distinction between components (Component) and objects (object) is defined first:A component is a reusable module that is a business object (Rules object) that consists of a set of processes, data encapsulation, and user interfaces. The component looks like an object, but does not conform to the academic definition of the object.The main differences are:1) A component can be used in another application called a container (sometimes referred to as a bearer or host) or as an independent proces
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

The component object model com is composed of Execution Code published in the form of Win32 DLL or EXE. Com is composed of some objects and object interfaces. In COM, interfaces provide object operation mechanisms. Interfaces are composed of one or more related methods, attributes, and events. Here we develop a simple but fully functional
DeveloperI often want to talk about Microsoft's future strategies in the following aspects: COM, Microsoft Transaction Service (MTS), and its JIT engine and Object Buffer (ObjectPooling ),Microsoft Message Queue (MSMQ) and DCOM. What is the relationship between websites, application servers, ASP, and component integration? Since everyone is clamoring for answers, let's solve the problem once.These problems exist. First, let me explain the issues relat
In addition to providing back-compatible,. NET Framework also supports forward compatibility, which is meant to be exposed. NET assembly is possible for COM utilization. Now let's see how we can get COM to leverage. NET assembly.
Calling. NET assembly from COM
Now let's look at the principle of using. NET assembly from COM
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

. 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

The highlighted row added in the Web.config file changes the lifetime of the client-activated object in this IIS VRoot from 6 minutes to 30 seconds. If you change the SingleCall property of the wellknown element to Singleton, the activa
Bahamuthttp://www.cnpack.org(reproduced please specify the source and remain intact)In a previous article, we introduced the interface. If you do not have contact with the COM object, you will feel that the interface is really troublesome, there may be: "Rather than directly define a class more convenient" idea.Indeed, interfaces without COM encapsulation are really troublesome. In my opinion, an interface
Delphi programmers develop COM + applications very quickly, mainly because it encapsulates the windows of COM +S underlying functions, developers can avoid complicated COM + underlying technical details through simple class inheritance, so that developers canFocus on the functions of the application. Delphi adopts many trade-offs when encapsulating
