                data[ilen]='\0';

			case FD_ACCEPT:

                len = sizeof(client);

     		listen_socket = accept(Socket,(struct sockaddr*)&client, &len);

     			if(listen_socket == INVALID_SOCKET)

     			MessageBox(hwnd,"Verbindung fehlgeschlagen!","Hinweis!",MB_ICONINFORMATION);    
                 else      
                 MessageBox(hwnd,inet_ntoa(client.sin_addr),"Clientdaten",MB_ICONINFORMATION);          
				return 0;

			case FD_CLOSE:

                       closewinsock(hwnd);
				MessageBox(hwnd,"Verbindung beendet!","Hinweis!",MB_ICONINFORMATION);      

				return 0;
}

So der Server macht keine Probleme... Er bekommt das FD_ACCEPT Event gepostet und reagiert dementsprechend... aber wenn der Server die Verbindung eingeht...bekommt der Client kein FD_CONNECT WARUM

Client Teil

void initwinsock()
{

	WORD wVersionRequested;
	WSADATA wsaData;

	wVersionRequested = MAKEWORD( 2, 0 );

	WSAStartup( wVersionRequested, &wsaData );

	}

void winsockconnect(HWND hwnd)
{
	connect_socket = socket(AF_INET,SOCK_STREAM,0);

	struct sockaddr_in addy2;

	addy2.sin_family = AF_INET;
        addy2.sin_port = htons(1234);
	addy2.sin_addr.s_addr = inet_addr("127.0.0.1");

        if(connect(connect_socket,(struct sockaddr*)&addy2,sizeof(addy2))==SOCKET_ERROR){
	MessageBox(0,"Bei connect()","Socket Error",0);}

else {                        

     WSAAsyncSelect(connect_socket,hwnd,WM_SOCKET_NOTIFY,FD_CONNECT|FD_READ|FD_CLOSE); }

}

void closewinsock(HWND hwnd)
{
    bytes = send(connect_socket,data,strlen(data),0);

    if (bytes == -1)
	{
		 MessageBox(hwnd,"Zeichen konnten nicht gesendet werden!","Hinweis!",MB_ICONINFORMATION);    

	} 

	WSASendDisconnect(connect_socket, NULL);
	closesocket(connect_socket);
	WSACleanup();
}

...

	case WM_SOCKET_NOTIFY:

              SocketEvent = WSAGETSELECTEVENT(lParam);   

			switch(SocketEvent)
			{
			case FD_READ:
				ilen = recv(connect_socket,data,255,0);
                data[ilen]='\0';

                MessageBox(hwnd,data,"Nachricht vom Server :",MB_ICONINFORMATION);   

				return 0;

            case FD_CONNECT:

                 MessageBox(hwnd,"Verbindung hergestellt!","Hinweis!",MB_ICONINFORMATION);   <-- DIESE MESSAGE BOX EINFACH nicht! :(

                 return 0;

			case FD_CLOSE:
                closewinsock(hwnd); 
				MessageBox(hwnd,"Verbindung beendet!","Hinweis!",MB_ICONINFORMATION);   

				return 0;
			}

Also wo liegt der Fehler ?
