Problem killing a thread

Hello,

I am creating a DLL that creates another thread and does its work.
When I load the library, it calls CreateThread which spawns another
thread. I am having a hard time terminating the thread. For some
reason, when it runs DLL_PROCESS_DETACH, and executes TerminateThread,
the thread does not terminate.

Would anyone know what I could be doing wrong?

It seems fairly simple. Thanks

I have the following code:

////////////////////////////////////////////////////////////////
long WINAPI Temp(long lParam) {
    int result;
    for(;;) {
            // my new thread
    }

    return 0;
}
BOOL APIENTRY DllMain( HANDLE hModule, DWORD ul_reason_for_call,
LPVOID lpReserved ) {

    HANDLE hThread = new HANDLE();
    DWORD dwID;

    switch( ul_reason_for_call )
    {
        case DLL_PROCESS_ATTACH:
            hThread = CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)Temp, NULL,
0, &dwID);
            break;

        case DLL_PROCESS_DETACH:
            TerminateThread(hThread, 0);
            CloseHandle(hThread);
            delete(hThread);
            MessageBox(NULL, "Detaching Process", "Note", MB_OK);
            break;

        default:
            break;
    }

    return TRUE;
}
