I have been writing and testing my code on win xp, and today when I tested it on win 98 it allways fails at binding the socket. WSAGetLast error is returning 0 so i don't know what is wrong. Anyone had similar problems?
[CODE]
WSADATA wsaData3;
sockaddr_in service;
service.sin_family = AF_INET;
service.sin_addr.s_addr = INADDR_ANY;
service.sin_port = htons(1336);
char recvbufer[1000];
int bytes;
int err = WSAStartup( MAKEWORD(1,0), &wsaData3 );
if(err)
MessageBox(NULL, "couldnt start", "err", 0);
SOCKET m_socket3 = socket( AF_INET, SOCK_STREAM, IPPROTO_TCP );
if ( bind( m_socket3, (SOCKADDR*) &service, sizeof(service) ) == SOCKET_ERROR ) {
MessageBox(hwnd, "Error starting up. Is another server running on this port?\n", "Error", MB_ICONSTOP);
err = WSAGetLastError();
sprintf(recvbufer, "%i", err);
MessageBox(NULL, recvbufer, recvbufer, 0);
PostQuitMessage(0);
}
if ( listen( m_socket3, 1 ) == SOCKET_ERROR ){
MessageBox(hwnd, "Error listening on socket.\n", "Error", MB_ICONSTOP);
PostQuitMessage(0);
}

Seems like you want to create service in MFC? But i would like to let you know Visual Studio 6.0 don't provide any Wizard Support for Services in MFC.

Though there are some free third party service framework available in market that can help you create a service skeleton, here is some links :-

hello,

i m developed a simple client-server application.
now i want that in my server i don't accept connections from a list of IP addresses. how do i accomplish it. After accept() call i tried to check the IP of the connecting client and then used closesocket() to close the connection. But the problem is that the client gets connected as the connect() call from the client side works. i don't want that to happen. i want that the server should not accept connection from the list of IPs rather than accepting and then breaking. how do i achieve it?

thanx in advance

Not possible if you use socket api. What you have to do is to detect the first SYN packet from client IP's and filter on that.

1. Use a firewall (external to your prog).
2. Code raw sockets... i.e be prepared to write your own TCP protocol Frown | :(

Raw sockets: look at ping.c sample in MSDN..
Raw packet capture library: http://www.winpcap.org
The above two will help you detect a SYN pkt from clients.

But you'll be wasting your time trying to code a conventional client-server prog using the above two methods.. you'll have to write the the entire TCP protocol suite yourself at the server end. Why dont you simply use a packet filter firewall at the server?

I suppose that you have a good level on networking programming
then do this if not just forget about, sorry

Normaly with Socket API it is not possible, because while calling accept() the client get connect.
For that you need to use some firewall in your program for packet filter
here is am easy way to do that:

INTERFACE_HANDLE hInterface; // interface
PFFORWARD_ACTION defaultAction=PF_ACTION_DROP;
// create the interface
// I create the interface. Predefined acctions, forward all.
DWORD errorCode = PfCreateInterface(0,defaultAction,defaultAction,FALSE,TRUE,&hInterface);
if(errorCode != NO_ERROR)
{
return -1;
}

// Bind the Ip Address with the interface
PBYTE lIp = (PBYTE)&ip; //the ip address of your card
errorCode = PfBindInterfaceToIPAddress(hInterface, PF_IPV4, lIp);

if(errorCode != NO_ERROR)
{
PfDeleteInterface(hInterface);
hInterface = NULL;
return -1;
}
/////////////////////////////////////////////////////
now here do with the code
{
DWORD result;
PIP_ADAPTER_INFO pAdapterInfo = NULL, aux;
IP_ADDR_STRING *localIp;
unsigned long len = 0;
GetAdaptersInfo(pAdapterInfo, &len);

pAdapterInfo = (PIP_ADAPTER_INFO) malloc (len);

result = GetAdaptersInfo(pAdapterInfo, &len);

if(result != ERROR_SUCCESS)
{
AfxMessageBox("Error getting adapters info.");
return;
}
// Fill the real filter struct
PF_FILTER_DESCRIPTOR ipFlt;
ipFlt.dwFilterFlags = FD_FLAGS_NOSYN;
ipFlt.dwRule = 0;
ipFlt.pfatType = PF_IPV4;
ipFlt.dwProtocol = protocol; // value is : TCP =6;UDP=17 or ICMP=1
ipFlt.fLateBound = 0;
ipFlt.wSrcPort = srcPort; // source port
ipFlt.wSrcPortHighRange = srcPort; // source port range
ipFlt.wDstPort = dstPort; // destination port
ipFlt.wDstPortHighRange = dstPort; // destination port range

unsigned long lIpSrc = CharToIp(srcIp); //chartoIP convert (*.*.*.*) to long
unsigned long lIpDst = CharToIp(dstIp);
unsigned long lMaskSrc = CharToIp(srcMask);
unsigned long lMaskDst = CharToIp(dstMask);

ipFlt.SrcAddr = (PBYTE) &lIpSrc;
ipFlt.SrcMask = (PBYTE) &lMaskSrc;
ipFlt.DstAddr = (PBYTE) &lIpDst;
ipFlt.DstMask = (PBYTE) &lMaskDst;
DWORD errorCode;

// I add the filter
if(direction == IN_DIRECTION || direction == ANY_DIRECTION)
errorCode = PfAddFiltersToInterface(hInterface,1,&ipFlt,0,NULL,NULL);

if(direction == OUT_DIRECTION || direction == ANY_DIRECTION)
errorCode = PfAddFiltersToInterface(hInterface,0,NULL,1,&ipFlt,NULL);
}

Not that when stopping your server
call PfDeleteInterface(hInterface); to delete your interface

What about Extended MAPI? Since you are interacting with Outlook, there's also CDO.

So you use Outlook2003.. not Outlook express. I personally don't have Outlook2003. But you may be able to locate the correct key in the registry yourself. Do a Find on the registry using a known E-mail account e.g abc@xyz.com. The key should show up in the find results.
