There are generally three methods to create a COM object. You can create an object normally and use the cocreateinstance function. If you create an object in a remote system, use the cocreateinstanceex funct

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 problem starts with this: I need to write a COM + to connect to different databases. Some friends might say that you should build a COM + for each database, but not in my system. We are doing an education-assisted system, the user is a school (including school teachers, students, parents), we build a database for each school, these databases are the same structure. Of course, we also have a management d

COM functions built into PHP4 are quite attractive for us to develop programs in the Win32 environment, but there is still not much relevant technical documentation. This article will deal with MS office Word, Excel, and Adobe Distiller in three examples to illustrate how to use COM functions in PHP.

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

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
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.

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
