Simple Sockets problem...

[SyntaxBubble]

I am creating a sockets program using Asynchronous sockets. Here's my problem. I do this:

WSAAsyncSelect(sockfd, hwnd, MY_MSG, FD_READ);

and I do:


WORD version=MAKEWORD(1, 1);
WSADATA data;

WSAStartup(version, &data);

And my program freezes and I have to do CTRL + ALT + DEL to end it. What do I do to stop this?

Could you provide a little bit more code? Are you calling those in that order?

WORD version=MAKEWORD(1, 1);
WSADATA data;

WSAAsyncSelect(sockfd, hwnd, MY_MSG, FD_READ);

switch (message) /* handle the messages */
{
case WM_CREATE:
WSAStartup(version, &data);

szRecvInfo=CreateWindowEx(
WS_EX_STATICEDGE,
"EDIT",
"",
ES_READONLY | ES_MULTILINE | WS_VSCROLL | WS_CHILD | WS_VISIBLE,
0,0,
400,200,
hwnd,
0,
hInst,
NULL
);

sockfd=socket(AF_INET, SOCK_STREAM, 0);

my_addr.sin_family=AF_INET;
my_addr.sin_port=htons(LSNPORT);
my_addr.sin_addr.s_addr=INADDR_ANY;

incoming=bind(sockfd, (LPSOCKADDR)&my_addr, sizeof(struct sockaddr));

incoming=listen(sockfd, 2);

.
. //Some code
.


case MY_MSG:
switch (WSAGETSELECTEVENT(lParam)) {
case FD_READ:
incoming=recv(con, szUsr, sizeof(szUsr), 0);

SetWindowText(szRecvInfo, szUsr);

GetWindowText(szRecvInfo, szInfo, 1000);

WSACleanup();
break;
}
break;
