IShellBrowser接口问题
准备用C#写一个类似资源管理器的控件，我参考了

Implementing   IShellBrowser   to   host   IShellView
http://www.codeproject.com/shell/explorer.asp

实现方法简介
1、窗体实现IShellBrowser接口，IShellBrowser.GetWindow返回了这个窗体的句柄
      IShellBrowser中的其他方法只是简单的返回-1；
2、调用IShellFolder.CreateViewObject，得到IShellView指针
3、调用IShellView.CreateViewWindow，创建显示子控件
4、view.UIActivate(SVUIA_ACTIVATE_FOCUS)，显示改控件

运行后能在窗体上显示出来一个资源管理器的子窗口，   现在的问题是在这个窗口上操作有60%左右的几率会出现下面的错误

我怀疑我的IShellBrowser借口定义有问题
