CHTMLView, View Source

I am using VC++6.0, Created a SDI App based on CHTMLVIEW

I use the following code to get & set the HTML source in the browser...


#include "mshtml.h"

CString CMyBrowserView::GetHTML()
{
     IHTMLDocument2* pDoc = (IHTMLDocument2*)GetHtmlDocument();
     IHTMLElement* pBody;
     pDoc->get_body ( &pBody );
     
     BSTR Body;
     pBody->get_outerHTML ( &Body );
     
     CString Page ( Body );
     ::SysFreeString (Body );

     return Page;
}

void CMyBrowserView::SetHTML(CString html)
{
     IHTMLDocument2* pDoc = (IHTMLDocument2*)GetHtmlDocument();
     
     IHTMLElement* pBody;
     pDoc->get_body ( &pBody );
     
     BSTR what = html.AllocSysString();
     pBody->put_innerHTML(what);
     ::SysFreeString (what);
}

But the above code only gets the body HTML and sets the body HTML.

What I need is a new function which gets the correct source.  Something that would get
the same source as when I would right click and go view source and it would open in notepad.. also like The IE->View Source

Also a fix on the setHTML function would be appreciated but not needed

// Get document.
IHTMLDocument2* pDoc = (IHTMLDocument2*)GetHtmlDocument();

// Get element collection.
CComPtr<IHTMLElementCollection> p2;
   
VERIFY(SUCCEEDED(pDoc->get_all(&p2)));

// First element.
CComPtr<IDispatch>      p3;
CComQIPtr<IHTMLElement> p4;
CComBSTR                bstr;
CComVariant             var1(0);
CComVariant             var2(0);
long                    lLength = 0;

VERIFY(SUCCEEDED(p2->get_length(&lLength)));
VERIFY(SUCCEEDED(p2->item(var1, var2, &p3)));
VERIFY((p4 = p3) != NULL);
VERIFY(SUCCEEDED(p4->get_tagName(&bstr)));
VERIFY(bstr == "HTML");
VERIFY(SUCCEEDED(p4->get_outerHTML(&bstr)));

bstr contains your "View Source".
