Software reuse is the goal pursued by the industry. People always hope to "Assemble" applications as they build blocks, and component objects act as building blocks. The so-called component object is actually a predefined service or interface that can complete certain functions. The question is, how do these component objects coexist with applications and other component objects and communicate and interact with each other? So what should I do? Standards, allowing these component objects to work
New Year's high trading continues. COM domain name again lead the coquettish
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
People familiar with object-oriented programming and network programming must be familiarActiveX,OleAndCOM/DCOMThese concepts are not unfamiliar, but many people are still vague about the relationship between them.
In the relationship between them, we should first clarify the components (Component) And object (Object. A component is a reusable module that consists of a set of processing processes, data encapsulation, and user interfaces (Rules object). The component looks like an object, but d

In-process COM server (in-process COM server) has been introduced briefly before, here, only some need to understand, understand the knowledge points, and then programming may be better; in-process servers are
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.

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
COM (Component Object Model, Component Object Model) is a binary and network standard created by Microsoft. It is also a component standard that Microsoft has vigorously promoted and widely recognized. In the com standard, the COM object is well encapsulated, and the customer cannot access the implementation details of the object. The only access channel provided

Both Microsoft Office XP and Microsoft Office 2003 support a new unified design structure used to generate applicationsProgramAdd-on programs to enhance and Control Office applications. These external programs are called com external programs. This article gradually discusses the Office com external program and describes how to use Microsoft Visual
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
Visual Java is a network-centric programming language, and many tasks that are difficult to accomplish with ASP scripts can be easily implemented in Java. At the same time, the best way to extend ASP applications is to join COM components. So, can you use Java to develop components for ASP? This paper illustrates the specific process of developing COM components in Visual J + + environment through examples.

1 Introduction
Advanced com projects often need to pass objects across threads to call these object methods in different threads to stimulate their events. The following article is intended for junior com developers who have basic com knowledge (such as understanding the iunkown

I. Create COM components with VC
1, VC new Project-> ATL project, enter name Comtest,comtest will be the name of the COM component.
2, to the ATL Project Wizard, do not need to change, complete the wizard. After the wizard completes, VC will automatically generate a series of programs.
