C++怎么获取网页元素的值？？？

[树上小蚂蚁]

我有VB写的获取网页元素值得源码 但是不知道C++怎么获取 麻烦各位大神帮忙解答一下

VB源码：
--------------------------------------------------------------------------------------------
Private Sub Timer1_Timer()
on error goto cw
dim jiesuoma as string
jiesuoma=Web.Document.getElementById("jiesuoma").Value
if len(jiesuoma)>=16 then
Web.Document.getElementById("jiesuoma").Value =""
调用第一个解锁码获取服务器参数
end if

cw:
End Sub
-----------------------------------------------------------------------------------------------

搜“CPP WebBrowser控件”

[lizhi5518]

UINT ElementClick::FrameElementInput(IDispatch *curDisp, CString csText, CString csID, UINT nFrame)
{
	CComQIPtr<IHTMLDocument2> pHtmlDoc2 = curDisp;
	HRESULT   hr;
	if(pHtmlDoc2)
	{
		CComPtr<IHTMLFramesCollection2> frame = NULL;
		hr = pHtmlDoc2->get_frames(&frame);//获取所有框架;
		if(SUCCEEDED(hr) && NULL != frame)
		{
			VARIANT var;
			var.vt = VT_I4;
			var.intVal = nFrame;
			CComVariant vDispWin2 = NULL;
			hr = frame->item(COleVariant((long)0),&vDispWin2);
			if(SUCCEEDED(hr))
			{
				CComQIPtr<IHTMLWindow2> spWin2 = vDispWin2.pdispVal;
				CComPtr <IHTMLDocument2> spDoc2;
				spDoc2 = HtmlWindowToHtmlDocument(spWin2);	//获取子框架Doc2;
				IHTMLElementCollection *spAllElement = NULL; 
				hr=spDoc2->get_all(&spAllElement);//获取子框架所有元素;
				if(SUCCEEDED(hr) && NULL != spAllElement)
				{
					IDispatch *pFrameDisp = NULL;
					VARIANT index;
					VARIANT varID;
					V_VT(&index) = VT_I4;
					V_I4(&index) = nFrame;			//我也不知道这里什么意思``暂时就这么写``出问题在说;
					varID = StringToVariant(csID);	//格式转换;

					hr = spAllElement->item(varID, index, &pFrameDisp);	//获取控件位置;
					if(SUCCEEDED(hr) && NULL != pFrameDisp)
					{
						IHTMLElement *pElement = NULL;
						hr = pFrameDisp->QueryInterface(IID_IHTMLElement, (void **)&pElement);	//获取元素接口;
						if(SUCCEEDED(hr) && NULL != pElement)
						{
							pElement->put_innerText(StringToBstr(csText));		//输入文字;
							pElement->Release();
							curDisp->Release();
							spAllElement->Release();
							pFrameDisp->Release();
							return ELEMENT_OK;
						}
						curDisp->Release();
						spAllElement->Release();
						pFrameDisp->Release();
						return FRAME_ELE_ERROR;
					}
					curDisp->Release();
					spAllElement->Release();
					return FRAME_FDISP_ERROR;
				}
				curDisp->Release();
				return FRAME_ALL_ERROR;
			}
			curDisp->Release();
			return FRAME_FDISP_ERROR;
		}
		curDisp->Release();
		return FRAME_FRAME_ERROR;
	}
	curDisp->Release();
	return FRAME_DOC_ERROR;
}

求结贴..赚点分.!!

取值的话...
CComVariant varAttribute;
CComBSTR bstrValue;
pElement->getAttribute(CComBSTR(_T("id"), 0, &varAttribute));
if (SUCCEEDED(varAttribute.ChangeType(VT_BSTR)))
{
bstrValue = varAttribute.bstrVal;
}

bstrValue 就只这个元素的id值``需要别的值``改getAttribute参数就行
