    Function problem (Winsock)

    I having a problem to start winsock2, check it out (It's dosn't connect):

    Code:
    #include <winsock2.h>
    #include <windows.h>
    #include <stdio.h>
    
    
    int connect()
    {
    
    	int sockfd;
    	struct sockaddr_in dest_addr;
    
    		WSADATA info;
    	    if (WSAStartup(MAKEWORD(1,1), &info) != 0)
      		  MessageBox(NULL, "Cannot initialize WinSock!", "WSAStartup", MB_OK);
    		else
    			{
    			MessageBox(NULL, "Cannot initialize WinSock!", "ERROR 216", MB_OK);
    			return(0);
    		}
    			
    	    sockfd = socket(AF_INET,SOCK_STREAM,0);
    		dest_addr.sin_family = AF_INET;
    		dest_addr.sin_port = htons(6667);
        		dest_addr.sin_addr.s_addr = inet_addr("bombers.no-ip.org");
    		if (connect(sockfd, (struct sockaddr *)&dest_addr, sizeof(struct sockaddr)) >= 0)
    			printf("\n%d", "Connected succesfully"); 
    		else
    		{
    			MessageBox(NULL, "Cannot initialize WinSock!", "ERROR 219", MB_OK);
    			return(0);
    		}
    }
    
    
    int main()
    {
    connect();
    }

    int IRCconnect()
    {
    	int sockfd;
    	struct sockaddr_in dest_addr;
    
    		WSADATA info;
    	    if (WSAStartup(MAKEWORD(1,1), &info) != 0)
      		  MessageBox(NULL, "Cannot initialize WinSock!", "WSAStartup", MB_OK);
    		else
    			{
    			//MessageBox(NULL, "Cannot initialize WinSock!", "ERROR 216", MB_OK);
    			return(0);
    		}
    			
    	    sockfd = socket(AF_INET,SOCK_STREAM,0);
    		dest_addr.sin_family = AF_INET;
    		dest_addr.sin_port = htons(6667);
        		dest_addr.sin_addr.s_addr = inet_addr("80.105.107.170");
    		if (connect(sockfd, (struct sockaddr *)&dest_addr, sizeof(struct sockaddr)) >= 0)
    			printf("\n%d", "Connected succesfully"); 
    		else
    		{
    			printf("%d",sockfd);
    			return(0);

    The source code, can you tell me if the

    and the else are correct?


    Source code:

    	return(1);
    	}
    		else
    			{
    			MessageBox(NULL, "Winsock started!", "OK", MB_OK);
    		}
    			
    	    sockfd = socket(AF_INET,SOCK_STREAM,0);

        		dest_addr.sin_addr.s_addr = inet_addr("80.105.107.170");
    		if (connect(sockfd, (struct sockaddr *)&dest_addr, sizeof(struct sockaddr)) >= 0)
    			printf("\n%d", "Connected succesfully"); 
    		else
    		{
    			//MessageBox(NULL, "Cannot initialize WinSock!", "ERROR 219", MB_OK);
    			printf("\n%d", "Connected...");
    		}
    }

    So, please, anyone can tell me if it's Ok?

    Just say if it's ok... :\

    Code:
    #include <stdio.h>
    #include <winsock2.h>
    #include <windows.h>
    
    int IRCconnect()
    {
    int sockfd;
    struct sockaddr_in dest_addr;
    
    WSADATA info;
    if (WSAStartup(MAKEWORD(1,1), &info) != 0) {
    MessageBox(NULL, "Cannot initialize WinSock!", "WSAStartup", MB_OK);
    return(1);
    }
    else
    {
    MessageBox(NULL, "Winsock started!", "OK", MB_OK);
    }
    
    sockfd = socket(AF_INET,SOCK_STREAM,0);
    dest_addr.sin_family = AF_INET;
    dest_addr.sin_port = htons(6667);
    dest_addr.sin_addr.s_addr = inet_addr("80.105.107.170");
    if (connect(sockfd, (struct sockaddr *)&dest_addr, sizeof(struct sockaddr)) >= 0)
    printf("\n%d", "Connected succesfully"); 
    else
    {
    //MessageBox(NULL, "Cannot initialize WinSock!", "ERROR 219", MB_OK);
    printf("\n%d", "Connected...");
    }
    }
    
    
    
    int main()
    {
    IRCconnect();
    }

    Shouldn't you tell your printf()'s to output strings instead of integers?
    Don't you dare hit me on the head, you know I'm not normal.

    >>printf("\n%d", "Connected succesfully");
    This should be
    >>printf("\n%s", "Connected succesfully");

    or better still

    >>printf("\nConnected succesfully");

    or maybe even

    >>puts("Connected succesfully");
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]

    >>> it's tell me that the winsock culd not start...

    Then it is also telling you why. From MSDN...

    >>>
    Code:
    Return Values
    The WSAStartup function returns zero if successful. Otherwise, it returns one of the error codes listed below.
    
    *** clipped ***
    
    Error Codes
    WSASYSNOTREADY Indicates that the underlying network subsystem is not ready for network communication. 
    WSAVERNOTSUPPORTED The version of Windows Sockets support requested is not provided by this particular Windows Sockets implementation. 
    WSAEINPROGRESS A blocking Windows Sockets 1.1 operation is in progress. 
    WSAEPROCLIM Limit on the number of tasks supported by the Windows Sockets implementation has been reached. 
    WSAEFAULT The lpWSAData is not a valid pointer.

    I didn't miss it, you did state that before, you said:
    It's dosn't connect
    Accurate questions get accurate answers (in most cases )
    When all else fails, read the instructions.
