菜单项被点击...没有反应

Question

这是一个完全新手的问题，因为我的领域是Java而不是C＃，但我得到了构建BHO的任务，并且达到了我需要菜单项的地步（在工具内部菜单）在我的代码中调用一个函数。

我读到我必须声明并实现IOleCommandTarget接口，我这样做了。现在我需要将这个类注册为一个COM对象。

显然要做到这一点，我需要用[ComRegisterFunction]声明几个函数，但即使如此，我也无法在regsvr32中注册它们。而uppon与DLL导出进一步检查查看器的功能似乎并不在那里:(

我在做什么错

预先感谢您

编辑：

好了，所以从我得到的评论我想，我的COM对象被正确注册，但仍然是我的问题依然存在：当我点击新创建的菜单项时，我没有任何反应或方式来调试真正发生的事情

这是我到目前为止的代码：

因为这是一个托管的DLL，您不能使用任何REGSVR32或“DLL导出查看器”。

要注册NET的DLL为COM互操作，使用Regasm
