Implements IDTExtensibility2的宿主程序如何开发

Implements IDTExtensibility2的宿主程序怎么开发？
IDTExtensibility2是个接口，实现插件连接到宿主程序。
比如OFFICE、VB等。它有几个接口事件：

VB code

Implements   IDTExtensibility2 Private   Sub   IDTExtensibility2_OnConnection(ByVal   Application   As   Object,   ByVal   ConnectMode   _         As   AddInDesignerObjects.ext_ConnectMode,   ByVal   AddInInst   As   Object,   custom()   As   Variant)         MsgBox   "You   connected   to   clsVBComTest " End   Sub Private   Sub   IDTExtensibility2_OnAddInsUpdate(custom()   As   Variant) 'End   Sub Private   Sub   IDTExtensibility2_OnBeginShutdown(custom()   As   Variant) ' End   Sub Private   Sub   IDTExtensibility2_OnDisconnection(ByVal   RemoveMode   As   AddInDesignerObjects.ext_DisconnectMode,   custom()   As   Variant) ' End   Sub Private   Sub   IDTExtensibility2_OnStartupComplete(custom()   As   Variant) ' End   Sub 

我们开发OFFICE插件时，就是这样写的。
现在的问题是我自己的程序怎么做成象WORD一样，
可以让别人通过这个接口做插件，插进来让我扩充软件的功能。

枕善居有一个VB编写的插件及调用示例，不知道这种方法对你有没有帮助：http://www.mndsoft.com/blog/VB6/Plugin.html
