This article will explain in detail what the principle of VB.NET calling API is. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

1.VB.NET calls API

The full name of API is Application Programming Interface, which can be called "application program interface" in literal translation. In a sense, API is a function provided by an operating system or a program itself for other programs to use. In the Windows operating system, there are thousands of Windows functions available to applications, and the API mentioned in this article refers to these functions.

2.VB and API

I wrote this article (instead of writing VC or other languages) because VB's support for API is not direct and incomplete; in use, Windows's API is written on the assumption that the caller is C or C++, so it is not convenient for VB to call API, and there are often unnecessary errors or do not understand how to use the situation. The object of this article is mainly the reading of API which has not been deeply studied.

If you don't want to know too many details, you can move to an appropriate function usage, either you don't know API at all, or you only know a few, and you don't know how to use many functions, or you want to go from this literature to more techniques for using API or even VB (I hope I can let you learn), I think you should read this article. But there is still a major premise, you must be a reader who already knows how to use VB, because there will not be a complete project to teach you to do from beginning to end, it may be a short declaration and calling code, or it may be a combination of several functions, if necessary, it will also describe the relevant content of VB skills, but there must not be a complete example demonstration.

3. Principles and agreements of this article

Because some of the uses of API are simple and complex, some can be used alone, and some can not be used alone, and the main uses of each API are different, it is difficult to judge which can be understood more easily, so this article tries to start with the more commonly used ones and those that can have a greater effect on the program. In order for most people to understand, if other aspects of knowledge are needed, they will also try to talk about it, so that readers can learn to use API and be able to use the knowledge in this article to deal with the new API.

This is the end of the article on "what is the principle of VB.NET calling API". I hope the above content can be of some help to you, so that you can learn more knowledge. if you think the article is good, please share it for more people to see.
