    					char outMessage[1] = "1";
    					nBytes = send(mySocket, outMessage, sizeof(outMessage), 0);

    >>char outMessage[1] = "1";
    The array size must be at least 2 to account for the null character implicit in string literals.

    So just say
    char outMessage[] = "1";
    and let the compiler do the counting for you
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
