I have an application that needs to:

1) Open a URL.
2) Do a File>Save As of type TEXT
3) Open the text file and do some processing on it for a report.

I know how to do everything but #2, i.e. get the HTML document currently open in IE to be saved in the TXT format.

See http://support.microsoft.com/support/kb/articles/Q292/4/85.ASP ('HOWTO: Programmatically Save an HTML Page to Disk'). The scoop is:

Accomplishing this task from a Visual C++ host is very straightforward. You can use an IWebBrowser2
interface to call the QueryInterface method for the IHTMLDocument2 interface. After you obtain a pointer
to the document, then call QueryInterface for the IPersistFile interface. After you obtain this interface
pointer, you can call the save method to save the file to disk.

   HRESULT          hr    = E_FAIL;
   IDispatch*       pDisp = NULL;
   IHTMLDocument2*  pDoc  = NULL;
   
   pDisp                  = m_webOC.GetDocument();

  if(SUCCEEDED(hr = pDisp->QueryInterface(IID_IHTMLDocument2,(void**)&pDoc)))
  {
      IPersistFile*     pFile     =     NULL;
      if(SUCCEEDED(pDoc->QueryInterface(IID_IPersistFile,(void**)&pFile)))
      {
    LPCOLESTR     file = L"c:\\test1.htm";
    pFile->Save(file,TRUE);
      }
  }

Am I just dumb or are all these IE related COM interfaces poorly documented and arcane?

I suppose they make perfect sense to those folks at Microsoft but I can never find what I need...
