As we all know, the main tools used for secondary development of AutoCAD are ObjectARX, VBA, and vlisp. But their advantages and disadvantages are obvious: ObjectARX has powerful functions and high programming efficiency, but its disadvantage is

An array is an ordered set of items of the same data type. To access an item in the array, you must use the array name and the offset between the item and the array start point. In C #, there are some important differences between the declaration

We should use Union according to convention in C. This is my article.ArticlePoints to be given. Although C ++ allows us to expand some new things, I suggest you do not do that. After reading this article, I think you probably think so too.C. Because

I recently received a project about C ++ that requires cross-platform functionality. Therefore, I have reposted a configuration blog. This post reposted the link: Http://henrya2.blog.163.com/blog/static/754514192008102342642940 1.
