C++ winsock gives 10038 error on bind() - c++

Question

um, first post here, this place seems to be all over google and i can usally find my solution with having to acually ask a question my self in any site/forums; but if i sweat any more bullets over this ima hunt down whoever developed winsock and shoot them (sorry for the anger i think ive turned over every rock in every corrner of the net with no luck.... breeaatheee.... wheew)
Im new to network programming, but have been working with C++ for the last three years on a hobby level, and also been playing with AS3 recently.
Im trying to write a server (for the client with is the AS3 project im also working on) and as far as i can tell this SOCKET is perfectly fine. im not re-creating it, multi-threading with it, no re-assignment or anything. no funny bisuness. simply trying to set it all up and bind() is spitting out that nasty 10038 right in my face.
Ive looked on MSDN, and i know very well that 10038 means "attempted operation on an invalid socket"; for the life of me i cant see where its invalid.
but enough of my rambling, heres the code: (functions.h is empty, havnt got that far along yet)
//Server for Project7 - Client written in AS3 under FlashDevelop. Developed under and for the Windows Operating System Enviroment
//All connections handled under TCP/IP on port 3011
//Client is URL locked to www.cutdev.com

using namespace std;
int main()
{
const int iReqWinsockVer = 2; // Minimum winsock version required
WSADATA wsaData;
if (WSAStartup(MAKEWORD(iReqWinsockVer,0), &wsaData)==0)
{
// Check if major version is at least iReqWinsockVer
if (LOBYTE(wsaData.wVersion) >= iReqWinsockVer)
{
SOCKET SocketListen;
SocketListen = (AF_INET,SOCK_STREAM,IPPROTO_TCP);
if(SocketListen == INVALID_SOCKET)
{
cout << "ERROR - could not creaate listening socket." << endl;
system("pause");
return 4;
}
sockaddr_in Listener, Channel1;
Listener.sin_family = AF_INET;
Listener.sin_port = htons(3011);
Listener.sin_addr.S_un.S_addr = INADDR_ANY;
int err = bind(SocketListen,(sockaddr*)(&Listener),sizeof(Listener));
if (!err == 0)
{
cout << "Listener binding failed!" << endl;
cout << err << endl;
cout << WSAGetLastError();
return 3;
}
}
else
{
// Required version not available
cout <<"Required version of Winsock not installed." << endl;
}
// Cleanup winsock
if (!WSACleanup() == 0)
{
// cleanup failed
cout << "WSACleanup Failed!!" << endl;
system("pause");
}
}
else
{
cout << "WSA Startup failed!" << endl;
}
return 0;
}
Thanks in advance for any help!

Error 10038 is WSAENOTSOCK:
An operation was attempted on something that is not a socket.
This error is returned if the descriptor in the s parameter is not a socket.
This happens since you omitted the call to socket() and SocketListen contains the value of the IPPROTO_TCP constant instead of a socket descriptor:
SocketListen = (AF_INET,SOCK_STREAM,IPPROTO_TCP);
should become:
SocketListen = socket(AF_INET,SOCK_STREAM,IPPROTO_TCP);
