上面用handle的方法不知道是否正确？
以上就是代码了，问题就是：
1.需要鼠标moveleave到cad窗口，才能实现select实体。
2. autodesk.autocad.applicationservices.application.documentmanager.mdiactivedocument.sendstringtoexecute("zoom o ", true, false, false);
ed.setimpliedselection(ids);
找到这个方法缩放到实体对象，不知道有其他方法没，缩放到窗口呢？？？
若用"zoom w"缩放到窗口，可以传输一个参数给cad系统知道么？？？
3.不知道怎么把文件传到论坛，所以只有这样贴代码了。
大家看看，有什么问题？？？？？
劳驾！！！

如果你用的cad2007及以上的版本，可以使用autodesk.autocad.graphicssystem.view 类的有关函数：zoom\zoomextents\zoomwindow
c#最适合开发autocad，因为它拥有vb容易的特点，却具有vc++的强大功能。
才鸟，老大
你说得这个我找到了，但是不知道怎么用啊？？？？拜托举个例子。！ [ ]

同请教这个view类应该如何使用，通过什么方法可以得到当前的view，
老大的书里有这方面的内容。
还没开始用arx编程呢，刚想学习
