C++ builder中动态改变浏览器中的内容

先在浏览器中放一个浏览器控件，名字叫wb，然后用下面的代码来实现

 

void __fastcall TForm1::SpeedButton1Click(TObject *Sender)
{
    IDispatch *wdoc = static_cast<IDispatch *>(wb->Document);
    IHTMLDocument2* pHtmlDoc2 = static_cast<IHTMLDocument2 *>(wdoc);
    if(pHtmlDoc2){
        HRESULT hr = S_OK;
        IHTMLElement *pBodyElement;
        hr=pHtmlDoc2->get_body(&pBodyElement); 
        if(pBodyElement!=NULL)  
        {     
            BSTR pbBody = L"中文测试";
            hr=pBodyElement->put_innerHTML(pbBody);   //类似的还有put_innerTEXT
            pBodyElement->Release();  
        }     
        pHtmlDoc2->Release(); 
        //if( hr==S_FALSE) return FALSE;
        //else return TRUE;
    }
    //else return FALSE;

}

已经实验过的，在2009中中文UTF8是正常显示的，貌似先前加载的css和js也是可以使用的，如果浏览器没有先加载过网页这段代码是不能使用的，不会报错
