请教如何使自定义的选择事件在所有文档中有效

编译后的DLL通过注册表加入了CAD自启动
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Autodesk\\R18.0\ACAD-8001:804\Applications\包]
"LOADER"="C:\工具包\LAND.dll"
"MANAGED"=dword:0001c101
"LOADCTRLS"=dword:0001c102
启动CAD时自动初始化
public void Initialize()
  {
                  Document acDoc = Application.DocumentManager.MdiActiveDocument;
                  acDoc.ImpliedSelectionChanged += new EventHandler(doc_ImpliedSelectionChanged); //设定自定义选择事件
}
问题出在这个初始化只在CAD启动时执行一次，后续开图，都未执行，所以当新开图后，这个选择事件也就失效了，
请教如何能让这个选择事件对所有及后续新建的Document都有效？
恭请各位老大们指点

public void Initialize()
{
aApp.DocumentManager.DocumentCreated += new DocumentCollectionEventHandler(DocumentManager_DocumentCreated);
aApp.DocumentManager.DocumentActivated += new DocumentCollectionEventHandler(DocumentManager_DocumentActivated);
}

using aApp = Autodesk.AutoCAD.ApplicationServices.Application;

谢谢老大，不过好像不管用，鉴于我对老大的指点出现了2种理解，均未成功，恭请继续指点.....
理解一：（依然只是在新建文件时只执行了一次）
using Autodesk.AutoCAD.Runtime;
using System;
using Application = Autodesk.AutoCAD.ApplicationServices.Application;
using Document = Autodesk.AutoCAD.ApplicationServices.Document;
namespace ClassLibrary1
{
public class Main : IExtensionApplication
{
      Autodesk.AutoCAD.EditorInput.Editor ed = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.Editor;
      public void Initialize()
      {
         Application.DocumentManager.MdiActiveDocument.ImpliedSelectionChanged += new EventHandler(doc_ImpliedSelectionChanged);
         ed.WriteMessage("\n+++初始化成功+++");
      }
      public void Terminate() { } //释放初始化，即CAD退出时才会执行
      public void doc_ImpliedSelectionChanged(object sender, EventArgs e)
      {
         ed.WriteMessage("\n++选择模式++");
      }
}
}
理解二（只要新建或切换文档立马致命错误）
