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

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

Web| Program | Component Development If you are an active Server page (ASP) developer, I believe you may often use COM objects to create ASP pages. Even when you use it, you ignore that he is a COM object. For example: ADO. The only component with the highest call rate is the ability to extend unlimited functionality to your page. However, the ASP itself is an interpretative script that is not functional en

The easiest way to create COM objects is by using the

COM, a component object model, describes how to create components and how to use components to create applications. 1. advantages of using components: One advantage of component architecture is that applications can evolve over time. In addition, you can also use components to upgrade existing applications more conveniently and flexibly, such as application customization, Component Libraries, and distributed components. The advantages of using comp

A question left at the end of the last article come back and give me a answer. You can see the following figure is clear: The conclusion is that T1,T2,T3 is three different references, that is to say, in.
