请问如何监听IE的动作，用BHO能监听前进，后退吗？

问题： 请问如何监听IE的动作，用BHO能监听前进，后退吗？
描述:

如下程序中的Invoke是根据dispidMember来进行操作的，我想知道
这些对应的宏是那里定义的，比如DISPID_BEFORENAVIGATE2，能否
监听到前进，后退的动作吗？
STDMETHODIMP CIEWebGuard::Invoke(DISPID      dispidMember, 
REFIID      riid,   LCID        lcid,  WORD        wFlags,
DISPPARAMS* pDispParams,   VARIANT*    pvarResult,                                 EXCEPINFO*  pExcepInfo,    UINT*       puArgErr)
{
CComBSTR bstrURL(szURL);
        switch(dispidMember)
{
    case DISPID_BEFORENAVIGATE2: // Before Naigation
        // IEBeforeNavigate2(pDispParams);
//MessageBox(NULL,"NC","OK",0);
//IENC(pDispParams);
//MessageBox(NULL,"BEFORENAVIGATE2","OK",0);
IEBeforeNavigate22(pDispParams);
//fprintf(fp,"BeforeNavigate2\n");
 break;
case DISPID_BEFORENAVIGATE: // Before Naigation
        // IEBeforeNavigate2(pDispParams);
//MessageBox(NULL,"NC","OK",0);
//IENC(pDispParams);
//fprintf(fp,"BeforeNavigate\n");
 break;
case DISPID_NAVIGATECOMPLETE:
//IENavigateComplete22(pDispParams);
//MessageBox(NULL,"NAVIGATECOMPLETE","OK",1);
//IENC(pDispParams);
//fprintf(fp,"NavigateComplete\n");
break;
        case DISPID_COMMANDSTATECHANGE:// Command state change
        // IECommandStateChange(pDispParams);
//fprintf(fp,"CommandStateChange\n");
 break;
         ...
 
}
//fclose(fp1);
    return S_OK;
