和ArcGis辅助编号（半自动）功能的插件式实现类似的工具，用于辅助精细化作业。
该工具同样使用了Windows API以摆放提示窗口，不同的是，本工具采用了“贴膜”的方式在ArcMap地图窗口上嵌入了一层透明窗体展示提示信息，并使用hook窗体消息的方法在ArcMap窗体调整时动态对“膜”的大小进行调整。
操作Windows窗口的API类在上面的“编号”博文里有说明，本文最后只附上Hook、处理窗体消息的API类。
一、工具功能
工具启用后，先选择目标图斑，然后开始按“北->东->南->西”的顺序依次点击邻斑，拾取其QLR字段的信息（显示到ArcMap地图窗口右上角），拾取完毕，按空格键（space）将拾取的四至信息写入目标图斑的四至字段（BZ、DZ、NZ、XZ）。
如果中途拾取错误，需重新拾取，按Esc键重新开始；
如果目标图斑不存在邻斑，可以使用数字键0-9键入预设地物信息（如果不是需要的，可以后面自行批量替换）：
1=>"空地",
2=>"道路",
3=>"河流",
4=>"小巷",
5 => "林地",
6 => "居民地",
7 => "园地",
8 => "湖泊",
9 => "水库",
0 => "池塘",
后面或许会把预设地物信息改为由外部文件获取。
二、Windows Hook API
使用嵌入窗体的方法在窗口上方展示四至信息，窗体的调整需要hook 窗口消息，hook API类如下：
using System; using System.Runtime.InteropServices; namespace YToolsforArcMap.Utils.WinAPI { public class HookAPI { /// <summary> /// 函数功能:该函数将一个应用程序定义的挂钩处理过程安装到挂钩链中去,您可以通过安装挂钩处理过程来对系统的某些类型事件进行监控,这些事件与某个特定的线程或系统中的所有事件相关。 /// 函数原形:HHOOK SetWindowsHookEx(int idHook, HOOKPROC lpfn, HINSTANCEhMod, DWORD dwThreadId); ///
