required in almost all GIS systems, and its core implementation is based on GIS components. Therefore, during the development process, developers often need to implement similar functions over and over again. This article describes how to encapsulate similar functions into a COM Component Based on VB event mechanism and object delegation. 2. Visual Basic event mechanism

What do we need? When we have traveled in a wonderful game world, or are amazed by the small and exquisite tools and software, there will always be some programming impulse. Programming? In the past, if you were a layman in the computer, it was really impossible. If you use a DOS-based programming language, such as C, Qbasic, Pascal, and so on, I do not know how many months can be achieved.
Programming requires talent. You must have a clear outline and an efficient process for the entire program
