怎样截获并处理IE的事件啊？

Question

我的程序是一个ActiveX文档服务器，当用IE打开特定类型的文档时会嵌入到IE并打开文档。就像用IE打开word文档的效果一样。我想在我得程序里处理IE的open file事件和鼠标拖曳事件（拖曳文档到IE并打开），该怎么办阿？

STDMETHODIMP CIEPlugCom::Invoke(DISPID dispidMember, REFIID riid, LCID lcid, WORD wFlags, DISPPARAMS *pDispParams, VARIANT *pvarResult, EXCEPINFO *pExcepInfo, UINT *puArgErr)
{

if(!pDispParams)
return E_INVALIDARG;

LPOLESTR lpURL=NULL;
m_spWebBrowser2->get_LocationURL(&lpURL);
switch(dispidMember)
{
case DISPID_BEFORENAVIGATE2:

if(pDispParams->cArgs >=5&&pDispParams->rgvarg[5].vt==(VT_BYREF|VT_VARIANT))
{
            CComVariant varURL(*pDispParams->rgvarg[5].pvarVal);
            varURL.ChangeType(VT_BSTR);
//转化要访问的网址为char *型
pURL=OLE2A(varURL.bstrVal);
}
//如果正要访问的网址为要被拦截的,则停止
//IDS_URL
if(strstr(pURL,"microsoft.com")!=NULL)
{
            *pDispParams->rgvarg[0].pboolVal=TRUE;
    MessageBox(NULL,"当前系统禁止浏览该页","警告",MB_ICONSTOP);

如何注册自己的协议，在IE中点击就能直接打开对应的可执行程序，类似于微软的mms协议那样的。  
是不是跟关联文件类型一样的？

是这样的，我想在我的程序里监视IE事件，比如当一个用户把一份文档拖到IE的地址栏时，我截获这个消息并为这份文档打开一个新的IE窗口。这样该怎么做啊？
