VC中修改IE网页滚动条的颜色和样式？

按照MSDN和网上搜集的资料我实现了如下的代码：

HRESULT STDMETHODCALLTYPE CWebCtrlInterFace::GetHostInfo(DOCHOSTUIINFO *pInfo)
{
	if (m_defaultDocHostUIHandler != NULL)
		return m_defaultDocHostUIHandler->GetHostInfo(pInfo);
	else
	{
		pInfo->cbSize = sizeof(DOCHOSTUIINFO);
		if (m_nStyle)
		{
			pInfo->dwFlags = DOCHOSTUIFLAG_NO3DBORDER|DOCHOSTUIFLAG_SCROLL_NO;
		}
		else
		{
			WCHAR* szCSS = L"<STYLE>\
							BODY{ \
							SCROLLBAR-FACE-COLOR: #00000;  \
							SCROLLBAR-HIGHLIGHT-COLOR: #FF0000;\
							SCROLLBAR-SHADOW-COLOR: #00FF00; \
							SCROLLBAR-3DLIGHT-COLOR:#53670D;    \
							SCROLLBAR-ARROW-COLOR: #53670D; \
							SCROLLBAR-TRACK-COLOR: #D4E597;      \
			                SCROLLBAR-DARKSHADOW-COLOR: #53670D; \
							SCROLLBAR-BASE-COLOR: #fcfcfc }\
							</STYLE>";

			size_t cchlengthCSs;
			HRESULT hr = StringCchLengthW(szCSS, CCHMAX, &cchlengthCSs);
			OLECHAR* pCSSBuffer = (OLECHAR*)CoTaskMemAlloc((cchlengthCSs+1)*sizeof(OLECHAR));

			hr = StringCchCopyW(pCSSBuffer, cchlengthCSs+1, szCSS);
			pInfo->pchHostCss = pCSSBuffer;
				 
			pInfo->dwFlags = DOCHOSTUIFLAG_NO3DBORDER;	                 
		}
		pInfo->dwDoubleClick = DOCHOSTUIDBLCLK_DEFAULT;
		return S_OK;
	}

但修改后还是没有效果，请教大神们应该怎样的修改网页中的颜色和样式

你的IE 浏览器用的是 那种， ActiveX 控件？还是别的？我不太懂，但你说出来可能有人明白
