C#资源管理器树控菜单实例，虽然界面不怎么样，不过实现了一个资源管理器的基本功能，包括图标显示方式、树形菜单的应用等，对想学习C#基础界面知识的新手来说，程序可参考的地方还挺多。编译注意，窗体上的那些图片资源有的搞丢了，编译进会提示有错误，不理会就是了。

本算法使用分治法求解最近点对问题。事先用O(nlogn)时间对x坐标进行排序，使得所有的点是按x坐标从小到大排好序的（x坐标相同时y坐标小的排前），然后取下标小于n/2属于左边的点集PL，取下标大于n/2属于右边的点集PR，即用O(1)时间就可以将规模为n的问题分解为两个规模为n/2的、同类型的子问题。分割完毕之后就可以采用分治法，分别求出PL和PR中的最近点对，最终通过递归实现。-This algorithm uses divide and conquer to solve the problem closest point. Prior to use O (nlogn) time to sort the x coordinate so that all points are based on x coordinates from small to large sorted (x coordinates with the same y coordinates of the small, the top), and then remove the standard is less than n/2 the set of points belonging to the left PL, remove the standard is greater than n/2 set of points belonging to the right of PR, that is to use O (1) time can be the problem size n divided into two size n/2, the same type The sub-problems. Segmentation can be used after completion of sub-rule method, respectively, find the PL and PR in the last points and eventually through the recursion.
