hi... I have written the following code in my BHO's
onDocumentComplete. What i want to do is that after my page gets
loaded i need to submit the form. Since there was no useful reference
on the net i wrote this thing myself.
can anyone cross-verify?? I managed to get to the IPIEHTMLFormElement*
pElement; line successfully. For www.gmail.com. The number of forms
returned was 1. So i got that element. But when I try to
queryinterface the
IPIEHTMLFormElement it fails. Please advice me to get past this line.
Below is my code sample

void __stdcall CBHOObj::OnDocumentComplete(IDispatch * pDisp, VARIANT
* pvtURL)
{
CComPtr<IDispatch> spDispDoc;

// Getting the current webpage from the browser
HRESULT res = m_spWebBrowser2->get_Document(&spDispDoc);

if(SUCCEEDED(res))
{
IPIEHTMLDocument2 *pHTMLDocument;
IPIEHTMLWindow2 *pHTMLWindow;
IPIEHTMLElementCollection *pHTMLElementCollection;
spDispDoc->QueryInterface( __uuidof(IPIEHTMLDocument2),
(void**)&pHTMLDocument);
if (pHTMLDocument)
{
pHTMLDocument->get_forms(&pHTMLElementCollection);
long pHTMLElementCollectionLength = 0;
if (pHTMLElementCollection)
{
pHTMLElementCollection->get_length(&pHTMLElementCollectionLength);
CString abc;
abc.Format(L"%ld",pHTMLElementCollectionLength);
MessageBox (NULL, abc,L"BHO", MB_OK);
for (int i = 0; i < (int)pHTMLElementCollectionLength ; i++)
{
VARIANT vtIndex,vtName;
vtIndex.vt = VT_UINT;
vtIndex.lVal = i;
vtName.vt = VT_UINT;
vtName.lVal = i;

IDispatch* pItem = NULL;

HRESULT hr = pHTMLElementCollection->item(vtName, vtIndex ,
&pItem);
if(SUCCEEDED(hr))
{
IPIEHTMLFormElement* pElement;
hr = pItem->QueryInterface(__uuidof(IPIEHTMLFormElement) , (void
**)&pElement );

if(SUCCEEDED(hr)) //E_NOINTERFACE
{
pElement->submit();
}
}
}
}
}
}
}
