基于VB+ArcObject组件进行的GIS二次开发，该软件源码是关于城市地下管网系统的。是相当成熟的市场软件，绝不是粗糙的个人毕业设计~~希望对GIS同行能够有所帮助。其实，对于一个GIS开发人员，二次开发能够读通或完成一个有难度的GIS项目就足矣啦~此例就能帮你完成由菜鸟到高手的进化~！-Based on VB+ ArcObject components of the secondary development of the GIS, the software source code is

在vb中用mapobjects添加图层，-Private Sub Form_Load() Dim dcnn As New MapObjects2.DataConnection Dim mlayer As New MapObjects2.MapLayer dcnn.Database = "G:\shape文件" dcnn.Connect Set mlayer.GeoDataset = dcnn.FindGeoDataset("bou2_4l") Map1.Layers.Ad
