This is the one I wrote to achieve Polygon click the numerical algorithm, the algorithm specifically designed, very fast, points can be judged in the float over the deformation or polygons, can migrate to Linux or UNIX platform, as the two platforms of no CRect PtInRect (), and the CLASS PtInRgn () function, which is a very efficient algorithm
