Strcmp is used to compare two strings, however, you might first want to check if 'inputtext' is NULL, and if it has numeric characters only.
'isnull' from the zcmd include:

PHP код:

#if !defined isnull
    #define isnull(%1) \
                ((!(%1[0])) || (((%1[0]) == '\1') && (!(%1[1]))))
#endif 


'IsNumeric' you have already been given.
The code should look something like this:

PHP код:

#define YOUR_SUPER_SECRET_CODE "1234567890"
if (dialogid == DIALOG_ACTIVATION)
{
    if (!response) return Kick(playerid);
    if (!isnull(inputtext))
    {
        if (!strcmp(inputtext, YOUR_SUPER_SECRET_CODE))
        {
            PlayerInfo[playerid][pActivated] = true;
            return 1;
        }
    }
    ShowPlayerDialog(playerid, DIALOG_ACTIVATION, DIALOG_STYLE_INPUT, "Oops! Something went wrong.", "You have entered an incorrect code. Please Try again.", "Activate", "Quit");
    return 1;
}
