实现了自己布置节点，布置路径，移动节点，并且能够查询两点间的最短路径，并用红色标出来。-Disposed node and, disposed path, the mobile node, and can query the shortest path between two points, and with red marked out.

VC++/MFC绘制图形，实现会制读取，鼠标移动可以捕捉节点，大家可以看看！ -VC++/MFC graphics rendering, implementation of reading, mobile mouse can capture node, you can have a look!
