Routine Description:

    This will load the given string from the applications string table.  If
    it is longer than MAX_STR_LEN it is truncated.  lpBuffer should be at least
    MAX_STR_LEN characters long.  If the string does not exist we return 0
    and set the buffer to IDS_STRINGMISSING, if that failes then we set it to the
    hard coded STR_RES_MISSING.

Arguments:

    uID - Id of the resource to load.

    lpBuffer - Buffer of MAX_STR_LEN to hold the string

Return value:
    
    0 - String resource could not be loaded.

    postive integer - length of the string loaded.
