Programming is one of them. VB is vertical and more manageable number of programming languages, and understanding one door computer language. VB as a programming language doors, and it has many advantages, such as : visualization design platform, object-oriented design methodology, and so on. The symbols on the map as an important element. Specifically, symbols can be divided into point symbols, symbols and noodle-shaped symbols developed. Noodle-shaped symbols refers to a two-dimensional plane, according to a certain scale that features spread symbols for objects or geographic distribution of warrants that face the phenomenon. Filling is often encountered in real life, a map of the region must demonstrate a community belonging to Ho, Ho objects that regional recharge. Regional recharge refers border region in a certain colour or fill pictorial. To the pentagon filling small circle, for example, face-shaped symbols to explore the filling. Inspired the design of specific programmes to fill in the programme design superiority and shortcomings analysis, thus improving the design of programmes. In the design process to achieve a face-shaped symbols add to the filling. Keywords: face warrants symbol; filling; Programming; Algorithm 目 录 摘 要 i Abs
