Hi,

Im writing a little webclient for http-sites. I want to use the cookies from InternetExplorer(6.0) since that is used as the main browser...
I need to get the cookies somehow. I tried it with InternetGetCookie, but it alwys fails. (returns false, but no errorcode). I also played with CInternetSession::GetCookie() but the same.

So how do I get all the cookies on site may have set from the InternetExplorers cache without knowing the name of the cookie?
And a second question, if i want to get subdomains, do i have to send the cookie from the topdomain too?

Thanks for any help :)

You can try searching the cookie directory - it is different in Win9x/NT - and retrieving the names from there.It can be a somehow complicated - you must check OS version, logged user etc. and then construct your path.After you get the names InternetGetCookie() seems to be working fine with them.

I tried it with the function InternetGetCookie(url,cookiename,cookiedata,size);

when I used it from VisualBasic it worked (was some years ago though) now it doesnt from c++.
And I dont think I need the cookie name (didnt need it under VB either)  since the msdn says  lpszCookieName : [in] Not implemented. So this function should actually get me all cookies from this site (did so in VB). So now Im wondering why it worked at that time but now fails under c++?

           LPTSTR lpData = new char[512];
            ZeroMemory(lpData,sizeof(lpData));
            DWORD dwSize = 512;
            BOOL bResult;
            bResult = InternetGetCookie("http://www.experts-exchange.com",NULL,lpData,&dwSize);
            if (!bResult)
            {
                  DWORD errCode = GetLastError();
                  printf("An error occured: %d", errCode);
            }
            else
            {
                  printf("Cookie data: %s\n",lpData);
            }
            getch();
            delete[] lpData;

The code above works well for me and retrieves the cookie.
