代码说明：

  //有机会下载安装了mapwingis，试图利用MFC对其二次开发利用，可惜网上能够查到的资料多为C#，VC资料太少。 //经过几天的研究，参考了网上网友的资料，利用VC实现了mapwingis部分功能的开发，为了和我有相同需求的码农们着想， //少走弯路，特开发部分示例代码，以抛砖引玉。 // 禾呈 && 博士 2019-5-30(After several days of research, referring to the information of netizens on the internet, the development of some functions of mapwingis has been realized by VC, for the sake of farmers who have the same needs as me.)
