Re: IHTMLDocument2->Write
Hi Igor,
How do I get URL's from HTML?
Can you suggest me?
When user click on anywhere of the Outlook mail, immediately it opens
webpage like ebay.com, benq.com... etc.
Now I have html body of that particular mail. Now I want to get that
particulat target link. How can I do?
Thanks in advance.
Rough code:
//pSA is html data from mail.
IHTMLDocument2* pDoc = NULL;
hr = CoCreateInstance(CLSID_HTMLDocument, NULL, CLSCTX_INPROC_SERVER,
IID_IHTMLDocument2, (void**)&pDoc);
hr = pDoc->write(pSA);
hr = pDoc->close();
IHTMLElementCollection* pECollection = NULL;
hr = pDoc->get_links(&pECollection);
LONG len;
hr = pECollection->get_length(&len);
for (LONG lIndex = 0; lIndex < len; lIndex ++)
{
BSTR bstrURL;
IHTMLElement* pHTMLElement = NULL;
pDisp->QueryInterface(IID_IHTMLElement,(void**)&pHTMLElement);
pHTMLElement->get_innerText(&bstrURL);
//HOW DO I GET LINKS from element?
}
Thanks in advance.
Regards,
Siri.

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly

Re: IHTMLDocument2->Write
Excellent.
It works fine.
1.)
Can I get charset value of HTML doc. like big5 or gb2312..etc?
BSTR htmlcharset;
I tried with pDoc->get_charset(&htmlcharset);
But, it is giving UNICODE always.
2.)
Can I get IP Address from the url?
Thanks in advance.

Siri.

Re: IHTMLDocument2->Write
Hi Igor,
Thank you for your cooperation.
IHTMLDocument2->write(); statement handles are increasing in task manager.
It is eating handles. How can I release handles?
obj.HrGetHTMLBody(lpMessage,&pszHTMLBody);//It returns HTML body in ascii
WCHAR* pbstrHTMLBody;
HrStrAToStrW(pHTMLBody,&pbstrHTMLBody);
SAFEARRAY *pSA;
SAFEARRAYBOUND aDim[1];
aDim[0].lLbound= 0;
aDim[0].cElements= 2;
pSA= SafeArrayCreate(VT_VARIANT,1,aDim);
VARIANT vOut;
VariantInit(&vOut);
vOut.vt= VT_BSTR;
vOut.bstrVal= SysAllocString(pbstrHTMLBody);
SafeArrayPutElement(pSA, &aLong, &vOut);
IHTMLDocument2* pDoc = NULL;
CoCreateInstance(CLSID_HTMLDocument, NULL, CLSCTX_INPROC_SERVER,
IID_IHTMLDocument2, (void**)&pDoc);
hr= pDoc->write(pSA);
if (pDoc != NULL){
pDoc->clear();
pDoc->Release();
}
VariantClear(&vOut);
SafeArrayDestroy(pSA);
MAPIFreeBuffer (pbstrHTMLBody);
Thanks in advance.

Siri.
