Getting loaded web page HTML source document from PIE web browser in windows mobile

Question

We need to get web page HTML source document loaded on the PIE web browser in windows mobile. source code that we tried is listed below:

IDispatch* pHtmlDocDispatch;
IOleCommandTarget* pOleCommandTarget;
WEBVIEWLib::IPIEHTMLDocument2*         pHTMLDocument2;
WEBVIEWLib::IPIEHTMLWindow2*           pHTMLWindow;

IPIEHTMLElementCollection* pHTMLElementCollection;

hr = pWebBrowser->get_Document(&pHtmlDocDispatch);
CHR(hr);

if (pHtmlDocDispatch != NULL)
{

     hr = pHtmlDocDispatch->QueryInterface(IID_IPIEHTMLDocument2,   (void**)&pHTMLDocument2);
     CHR(hr);

hr = pHTMLDocument2->get_parentWindow(&pHTMLWindow);
CHR(hr);

pHTMLDocument2->get_innerHTML() ... oh. bugger.
}

We have found that getting innerHTML() method is missing in Windows Mobile version of web browser control(PIE).

Now how should we obtain a HTML document from the PIE control. Is their an possible solution?

Thanks, Ramanand

Well, I've never developed for PIE, but I know the IE activeX interfaces reasonably well. If you have an IDispatch* pointer for the document element, you should be able to just use the IDispatch interfaces to get the DISPID for "innerHTML" and then call Invoke with DISPATCH_PROPERTYGET to get the value.

Similarly DISPATCH_PROPERTYPUT should be able to set the value, though it bears mentioning that to do a propertyput you may need to also include a named arg with DISPID_PROPERTYPUT in it.
