ArcGIS flex API provides several common geometric figures, such as points, lines, and surfaces. When more geometric figures are needed, you need to expand the geometry in ArcGIS flex API. The general idea is to expand the polygon and the polyline of the linear ry. Polygon consists of an array of rings, while polyline consists of a path. Both ring and path are essentially an array of mappoint. Take a star as an example: Package gispace. arcgisapiex. ge

This article describes how to use an asynchronous method to eliminate the performance problems of web service calls using Microsoft ASP. NET and the consumption of thread pool resources. Situation: Performance damage when Web services are called from ASP. NET pages When we discuss web services in this article, we hope to enjoy web services in various situations. One major case is to access the Web service from an intermediate layer environment (such as an ASP. NET web page. People who provide s
