COM object createdAnd then how to call the COM component. Here is the method for calling the COM Object in C ++.
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
Although COM technology has not been recommended by Microsoft, I still have a simple record of how to debug a COM component.
It's almost like debugging a normal DLL, a little different.
1. Creating COM components
Now use vs to create COM components is very easy, can use c++/vc++ or C #, indifferent C # to write
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

2009 out of the sight of people, ushered in 2010 years, in this old year, the domain name transaction also brought good luck. Digital Domain name 1199.com in Christmas Eve to 230,000 sold, the world's tallest high-rise caliph sent a high 160828.com domain name 160,000 of the price, and
In this article, we will discuss the following questions:
• Create a simple COM object using C # (using COM's interop attributes).
• Access COM from VC + + client software. The client software uses the TypeLibrary (. tlb file).
For simplicity and convenience for developers to use and test, we used the Northwind database in the default installation of SQL Server database software.
• Modify the name of SQ
What kind of software products do users need? This is a multiple-choice, but efficient, robust is sure to be selected. What does a software developer do to satisfy a user's needs? You must ensure that the upgrade application does not break backward compatibility with previous versions. You must extend the system service without relying on a specific operating system. Object-oriented programming is clearly a revolutionary change. Using object-oriented design method, we can easily abstract the pro

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
event handling in native C + + when handling native C + + events, you set the event source and event sink separately using the event_source and event_receiver attributes, and specify Type=native. These attributes allow classes that apply them to fire and handle events in a native non-COM context. declaring an event in the event source class, you can declare the method as an event by using the __event keyword for a method declaration. Make sure tha

1. How to create COM objects
Clients can create COM through the CoCreateInstance function, and must know some basic things about the object before it is created, such as the CLSID of the object or the ProgID of the object.
Another object creation method is created by a moniker (moniker), which is the use of object naming and binding techniques (i.e., name technology).
2, the status of the name technology
Microsoft Java compilers, virtual machines, and a wide variety of tools greatly simplify the work of java/com programmers compared to c++/com programmers. The compiler has special boot commands and packages that can treat Java classes as COM classes. In most cases, however, we simply rely on the support provided by the Microsoft JVM for
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

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
