    NAME:       ALERTS_DIALOG

    SYNOPSIS:   This class allows the user to set which computers will
                recieve alerts generated by NT.  The list is stored in
                the registry.

    INTERFACE:  Constructor

        GetComputerListFromRegistry
        SetComputerListInRegistry
            Read and write (and lock and unlock) the list of computer names
            stored in the registry.

        LockServicesDatabase
        UnlockServicesDatabase
            Attempts to take the lock on the services database.


    PARENT:     DIALOG_WINDOW

    USES:       PUSH_BUTTON, STRING_LISTBOX, SLE, SLE_STRLB_GROUP

    CAVEATS:    If ERROR_LOCK_FAILED is returned from construction then we
                were unable to lock the services database.  Note that the
                user will already have been notified of this.


    NOTES:      The lock on the services database is not maintained while the
                dialog is displayed (i.e., we relock the database when we
                go to write the computer names).

        KeithMo 03-Aug-1992     Now handles downlevel case.
