Hi, i was wondering if someone could show me how to log into a website using c++ .net? I want to login to say megaupload.com for example, now i have to code in c++ but how could i do it in managed c++? A link or something would be great, i see many examples of this in c# but not in c++ =/. Thanks

#include <winsock2.h>
#include <windows.h>
#include <string.h>
#include <stdio.h>


#pragma comment(lib,"ws2_32.lib")

#define HOST "www.megaupload.com"
#define PORT 80

#define LEN 534 // Points to contenth length in http_req[]

int hconnect(char* host,int port);
int s=0;

char http_req[]=
"POST /?c=login HTTP/1.1\r\n"
"Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, application/xaml+xml, application/vnd.ms-xpsdocument, application/x-ms-xbap, application/x-ms-application, */* \r\n"

"Content-Length: 00\r\n" // LEN points here!!!
"Connection: Keep-Alive\r\n"
"Cache-Control: no-cache\r\n\r\n";

char http_line_req[]="login=1&redir=1&username=usernamehere&password=passhere\r\n\r\n"; // fill in here

char conn[1024];

int nLen=0;
char szLen[2];

void main()
{
nLen=strlen(http_line_req);
itoa(nLen,szLen,10);
memcpy(http_req+LEN,szLen,2);

s=hconnect(HOST,PORT);

send(s,http_req,strlen(http_req),NULL);
send(s,http_line_req,nLen,NULL);
recv(s,conn,1024,NULL);
//TODO: continue recv'ing, that 1KB buffer is not enough to recv all the data :)
}

int hconnect(char* host,int port)
{
WSAData wsa;
WSAStartup(MAKEWORD(1,1),&wsa);

struct sockaddr_in sai;
struct hostent *hp;

memset(&sai,0,sizeof(struct sockaddr_in));

hp=gethostbyname(host);

sai.sin_family=AF_INET;
sai.sin_addr=*((struct in_addr *)hp->h_addr);
sai.sin_port=htons(port);

SOCKET s;

s=socket(AF_INET,SOCK_STREAM,0);
connect(s,(struct sockaddr*)&sai,sizeof(sockaddr));
return s;
}

Use/Learn methods of HttpWebRequest class.

>i see many examples of this in c# but not in c++

You could write your managed HttpWebRequest code into a C#, and compile it as a DLL. Use RegAsm.exe to register it as a COM object.
