Overview
If you use ASP for development, you may have used com on your ASP page. however, before you develop a com part or read a book about com, you may not fully understand COM, so you cannot use it to create your ASP page. at the same time, you cannot understand the usage documents that come with
Differences between components and objects
First, identify the differences between components and objects. 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 does not conform to the academic Definition of the object. Their main differences are:
A component can be used in another application called a container (sometimes called a container or host) or as an independent
Today I went to SQL Server 2005 and installed it for research.
The installation process was not very smooth, mainly due to COM + errors. I searched the internet and solved the problem as follows:
The installation is successful as follows.

In the previous blog, we used Visual Studio to convert the. NET Component (managed component) into a COM server. This topic continues to show you how to use the. NET toolkit to complete relevant functions.
First, let's take a look at the relationship between today's topic and CLR InterOP. In our group, th
Introduction
This article is intended to explain the concept behind connection points with a clear practical example, which will demonstrate an in-process COM server and an MFC client that uses the server.What exactly is it?
It is a method used by a COM object to call back to the client. In other words, clients get call back notification from the COM object.

When I was working on a project a while ago, I encountered the call and use of the COM component. At that time, I had a good research, so I had to get through the intermediate link. Now I wrote it to help you, there are four types:
1. In vs2005, C # compiles a DLL and calls it using C ++.
2. Use vc6.0 to call the COM component written in C # In vs2005
3. Compile COM

Microsoft has tightly integrated the capabilities of IIS and COM +, which makes it very easy to leverage transactional applications in the process of programming the transaction Web page. There are many different ways to integrate the transaction characteristics of COM + and IIS, including the following:? Transactional ASP.? The ObjectContext in ASP.?

Well, I used to ask this question, no one said, or do it yourself better.
Generally, when a COM object is provided, it usually provides a type library in which all the method names, parameter names, property names, and so on of the COM object are defined. All we have to do is ta
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
Go to Windows Service series-add COM and Windows interfaces to windows Services
When running a Windows service, we usually choose to run it in Non-window or non-Console mode. In this way, it is just a background program, there is no interface for interaction.
So what should we do when we want to interact with the Windows Service in real time?Quick Solution for adding real-time interaction to Windows Services

-- The method parameter types are cruntimeclass * and void *.
I often see questions on the Forum about how to pass void * or a custom class, such as class Ca and Ca. This article describes how to pass a pointer to a custom Class Object and clarify the role of midl, so that it is not necessary. Note that the transfer of custom types mentioned in this article is not the same concept as the transfer of custom structure
The services|web|xml| check box compiles and runs this Visual Basic. NET application, producing the same output as the previous two VBScript samples.
Because the server application publishes components as CAO and Wko two forms, the remote client chooses the activation method. Although it may only make sense for academic research, a single client computer can indeed use two remote activation methods of the same component to access the virtual root of the same SOAP publication on a remote server.
