Hello !
I'm having problems to obtain the HTML source from webpages that refresh its 
content dynamically by javascript functions.
in example:
http://articulo.mercadolibre.com.ar/MLA-25012974-notebook-hp-nx-6325-con-micro-sempron-3400-y-gtia-real-_JM

If I use this code (which works very well most of the times):
//----------------------------------
AnsiString TInternetExplorer::SourceCodeHTML(TCppWebBrowser* CppWebBrowser1)
{
  AnsiString Source = "";

  IHTMLDocument2 *htm = NULL;     // #include <mshtml.h>


if(CppWebBrowser1->Document&&SUCCEEDED(CppWebBrowser1->Document->QueryInterface(IID_IHTMLDocument2,
(LPVOID*)&htm)))
    {
    IPersistStreamInit *spPsi = NULL;    // ocidl.h


if(SUCCEEDED(htm->QueryInterface(IID_IPersistStreamInit,(LPVOID*)&spPsi)) && 
spPsi)
       {
            IStream *spStream = NULL;            // objidl.h
            OleCheck(CreateStreamOnHGlobal(NULL, true, &spStream));
            if(spStream)
            {
                __int64 nSize = 0;
                STATSTG ss;
                LARGE_INTEGER nMove;
                nMove.QuadPart = 0;
                OleCheck(spPsi->Save(spStream, true));
                OleCheck(spStream->Seek(nMove,STREAM_SEEK_SET,(ULARGE_INTEGER 
*)&nSize));
                OleCheck(spStream->Stat(&ss, STATFLAG_NONAME));
                nSize = ss.cbSize.QuadPart;

                Source.SetLength(nSize);
                OleCheck(spStream->Read((void *)Source.data(), 
nSize,(ULONG*)&nSize));
                OleCheck(spStream->Release());
            }

            spPsi->Release();
        }
    htm->Release();
    }
   return Source;
}
//------------------------------------------------------------------------

I can't find the data that I'm seeing in my screen.
My solution (very inefficient) was to wait for the page loads completly, 
then select all, copy to clipboard and then "paste" it to an AnsiString... 
it works, but it has many problems, for example, I loss the content of the 
clipboard, it's very imprecise, requieres a lot of extra code and resources, 
etc.
Can somebody post a better solution? (if it's possible... I think yes, that 
is, if the TCppWebBrowser can show the content then, the content is in 
somewhere...)

Thanks !
enrique.
