[HELP]WinINet login to facebook.com!

I need to login to facebook, but my code doesnt work:

#include <windows.h>
#include <wininet.h>
#include <string>
#include <iostream.h>

using namespace std;

void main()
{

string m_strURL;

HINTERNET hSession, hDownload, hRequest;

hSession = InternetOpen("MFFS", INTERNET_OPEN_TYPE_DIRECT, NULL, NULL, 0);

hDownload = InternetConnect(hSession, "login.facebook.com", INTERNET_DEFAULT_HTTPS_PORT, NULL, NULL, INTERNET_SERVICE_HTTP, 0, 0);

hRequest = HttpOpenRequest(hDownload, "POST", "/login.php?login_attempt=1", NULL, NULL, NULL, INTERNET_FLAG_SECURE, 0);

HttpSendRequest(hRequest, NULL, 0, "[email protected]&pass=123123123", 401);

if ( hRequest )
{
CHAR buffer[1024];
DWORD dwRead;
while ( InternetReadFile( hRequest, buffer, 1023, &dwRead ) )
{
if ( dwRead == 0 )
break;

buffer[dwRead] = 0;
m_strURL += buffer;
cout << buffer << endl;
}
}
}

Any idea whats wrong?
Thanks!

Websites these days don't simply rely on the form fields data, there may be a host of other security measures implemented against people like you :) The form itself may have hidden data fields, it may use cookies and reloading of the page for repeated authentication. I'm sure, facebook uses all that as well.

Facebook doesn't have a lot of security in the way you login... I made a script in php with curl to login to facebook, it was very easy... But with WinINet idk what is the problem:
I dont get a msg like:
Cookies Required

or

You are using an incompatible web browser.

or

Incorrect Email/Password Combination

So i fink I'm not even sending POST data....
I used tamper data to see what is necessary to login to facebook and you only need the pass and the email (there are 4 more hidden fields like char_set passholder etc...)
But i still cant find where is the problem :*(

Here is the new code:
#include <windows.h>
#include <wininet.h>
#include <string>
#include <iostream.h>

using namespace std;

void main()
{

static char hdrs[] = ("Content-Type: application/x-www-form-urlencoded");
static char frmdata[] = ("[email protected]&pass=qwertyasdf");
static LPSTR accept = ("*/*", NULL);

string m_strURL, url;

HINTERNET hSession, hDownload, hRequest;

hSession = InternetOpen("MFFS", INTERNET_OPEN_TYPE_DIRECT, NULL, NULL, 0);

hDownload = InternetConnect(hSession, "login.facebook.com", INTERNET_DEFAULT_HTTPS_PORT, NULL, NULL, INTERNET_SERVICE_HTTP, 0, 0);

hRequest = HttpOpenRequest(hDownload, "POST", "/login.php?login_attempt=1", "HTTP/1.1", NULL, NULL, INTERNET_FLAG_SECURE, 0);

HttpSendRequest(hRequest, hdrs, strlen(hdrs), frmdata, strlen(frmdata));

if ( hRequest )
{
CHAR buffer[1024];
DWORD dwRead;
while ( InternetReadFile( hRequest, buffer, 1023, &dwRead ) )
{
if ( dwRead == 0 )
break;

buffer[dwRead] = 0;
m_strURL += buffer;
cout << buffer << endl;
}
}
}


Now the problem are cookies :P
