Hi guyz. I am making a client-server application uysing CAnsySocket. A little history may help you assist. I made the application and was working just okay but the problem was that two client app. could not connect to the server. It always crashed. A viable solution to that was making a multi threaded server. Now, i have set worker threads for accepting the connection (For listening it is using the main thread). Below is the accepting code:

OnAccept()
{
    THREADPARAMS * pSocket; // THREADPARAMS is a structure defined in .h
    AfxBeginThread(AcceptFunc, pSocket);
}
UNIT AcceptFunc(LPARAM pParam)
{
    THREADPARAMS * pSocket;
    pSocket->m_sServerSocket.Accept(m_sClientSocket);
}
//in my .h
typedef struct THREADPARAMS
{
    CMySocket m_sServerSocket, m_sClientSocket;
}

the error is in line 9. The code is compiling just okay but when the client tries to connect the server crashes. Now, when i debug, it us taking me to line 9. Things to do with the parameters. I have trapped an error that i would expect if the client cannot locate the server but since that error is not popping, the server is listenning just okay, just the accepting part. Please assist me.

pSocket is not initialized. You need to assign a valid value first.
