Hello.

I want to display html information made in memory.

Is there a problem in the usage of the program?

 LPDISPATCH lpDocDisp = NULL;
 HRESULT hr = m_HtmlCtrl.m_pBrowser->get_Document( &lpDocDisp );
 if( FAILED(hr) || lpDocDisp == NULL ){
  return ;
 }
 IHTMLDocument2 * lpHtmlDoc2 = NULL;
 hr = lpDocDisp->QueryInterface(
  IID_IHTMLDocument2,
  (void**)&lpHtmlDoc2
 );
 SAFEARRAY *sfArray;
 VARIANT *param;
 BSTR bstr = SysAllocString(OLESTR("<H1>TEST</H1>"));
 sfArray = SafeArrayCreateVector(VT_VARIANT, 0, 1);
 hr = SafeArrayAccessData(sfArray, (LPVOID*)&param);
 param->vt = VT_BSTR;
 param->bstrVal = bstr;
 hr = SafeArrayUnaccessData(sfArray);
 hr = lpHtmlDoc2->write(sfArray);
 lpHtmlDoc2->close();
 
 SafeArrayDestroy(sfArray);
 SysFreeString(bstr);
 
 lpDocDisp->Release();
 lpHtmlDoc2->Release();

Hello.

I want to display the html.

So I use WebBrowser2.

Thank you very much for your advice.

Looks like correct. But some errors are present. Please invoke the SafeArrayDestroy(sfArray); last and not invoke the SysFreeString(bstr); because the string handle is destroyed by the SafeArrayDestroy(sfArray); code.

If you need a log view window with colorized text output, then you can get it from the MthOutput sample application.
