void CMyWebBrwoser2Event::WindowStateChanged(DWORD dwFlags, DWORD dwValidFlagsMask){return;}


然后自定义CMyWebBrwoser2Event brwoser2event;对象时仍然提示

DWebBrowserEvents2可以看作为IDispatch接口，得通过Invoke来完成事件的处理

原来还需要再实现这几个方法
c#制作的扩展浏览器源码
本扩展浏览器以原.net自带的WebBrowser为基类扩展，实现了以下功能： 1、实现了IDocHostShowUI接口，可以截获弹出对话框事件 2、实现了DWebBrowserEvents2接口，可以在本窗口显示弹出窗口 3、实现了其他的一些接口，以实现浏览器的高级功能
