Overview
If you use ASP to do development, you may have used COM in your ASP page. However, before you develop a COM widget yourself or read a book detailing com, you probably don't fully understand COM, so you can't make the most of it to create your ASP page. Nor do you have a good understanding of the usage document
A typical scenario in COM is to have the client object instantiate the server object and then invoke the objects. However, without a special mechanism, these server objects will be difficult to turn to and callback to client objects. COM Connection points provide this special mechanism to achieve two-way communication between the server and the client. With connection points, the server can invoke clients w
This paper describes in detail the method of modifying the COM directory in the pseudo static address of Destoon member company, which has certain practical value. Share to everyone, I hope to help you destoon development.
Generally speaking, the pseudo static default of Destoon Enterprise website is com directory, want to change words first open the Include directory under Global.func.php file

Today is very happy, the project finally on-line use. Just the problems before the line tortured people exhausted ... But finally solved. In this problem to speak out, I hope to have the need to provide some help to friends ~ ~
Project: Dotnet project, C # Development, the main function is to access the remote interface through COM components.
Operating environment: Windows 2003 Server + IIS6.0 +. Net 1.1
Problem:
First, the preface
1, with the "COM Component design and application (V)" content is basically consistent. But this is explained in Vc.net 2003 use method, even if you no longer use vc6.0, also please and the previous back of the content, reference comparison.

ActiveX control is a powerful program design and development technology provided by Microsoft. ActiveX control is both an Automation object (and, of course, a standard COM object) and an interface element, as is common control in Windows.
ActiveX control is a comprehensive technology that involves many of the technical essences of COM and OLE, and is closely integrated with Windows oper

Windows lets share code at the binary level using DLLs. After all, that's how Windows apps function-reusing Kernel32.dll, User32.dll, etc. But since the DLLs is written to a C interface, they can is only is used by C or languages that understand the C calling con Vention. This puts the burden of sharing on the programming language implementer, instead of the DLL itself.MFC introduced another binary sharing mechanism with MFC extension DLLs. But these is even more restrictive-you can only u

The. NET framework has been in production for more than two years, and many companies have begun to adopt it. NET development application software. But many companies have developed a lot of COM, DCOM components in many years of project applications, now adopted. NET development components, making these components legacy code. Because of the large amount of manpower and resources invested in the development of COM
First, the question of the proposed: (Listed below I encountered the problem)
1, each request of end user, will read mapping file--can be solved by caching;
2, the XXX subsystem needs to write mapping files--can also be written to memory and then bulk write file to solve;
Second, the analysis solves the problem:
Since there are 2 or more subsystems that need to read and write to the same file, and the client has great concurrency, there is a high likelihood of read-write conflicts or errors, wh
This article uses VB6 as an example to introduce two simple examples of. NET referencing COM and COM referencing. NET.
In order to be simple, we use VB6, which is said to be an old antique about open source, to create a simple COM.

I have never been quite clear about the term "apartment", but they always like to answer the question in an attempt to ask people on the Forum: "You should read the" com essence "carefully." In fact, if some of the key parts do not understand it, it won't work even if we read it for ten times. What we need is a suitable teaching material.

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.
