想要获取网页文本框控件内容(非密码文本框,比如论坛发帖子的文本框),试了一些方法,比如,用Spy++和GetWindowText,可以获取Eidt控件的内容,但这种发帖子的控件类型好像很特别,所以获取不到.
  我下载了一个软件源码,它可以获取网页文本框中的内容,但就是不能获取论坛发帖子的文本框的内容,是不是因为这种文本框的类型与其他的文本框不同呢??

部分关键源码:

    CComPtr<IDispatch> spDispatch;
    CComQIPtr<IHTMLDocument2, &IID_IHTMLDocument2> pDoc2;

    CComPtr<IHTMLElementCollection> pElementCol;
    CComPtr<IHTMLFormElement> pFormElement;
    CComPtr<IHTMLInputTextElement> pInputElement;
    // TODO: Add your control notification handler code here
    int n = m_ctrlIE.GetItemCount();//GetCount();
    
    for (int i = 0; i < n; i ++){
        IWebBrowser2 *pBrowser = (IWebBrowser2 *)m_ctrlIE.GetItemData(i);
        if (pBrowser){
            pBrowser->Release();
        }
    }
    
    m_ctrlIE.DeleteAllItems();

        int n = m_spSHWinds->GetCount();
        for (int i = 0; i < n; i++){

            IDispatchPtr spDisp = m_spSHWinds->Item(v);
            
            
            SHDocVw::IWebBrowser2Ptr spBrowser(spDisp);   //生成一个IE窗口的智能指针

想请问各位有什么高见???
