INTRODUCTION The Windows 7 login script I inherited

Displays a login screenPerforms account authenticationChecks for blank usernames and

passwords less than 8 charactersAuto login capability does not work. Auto login implemented using

threading.

FLOW CHART

REQUIREMENTS: AUTO SHUTDOWN Shutdown the computer at any

scheduled time

REQUIREMENTS: AUTO LOGIN Create a 2 GB H: drive partition Run login.vbs Run LibraryDefaultPage.vbs Display desktop

UNIX TIMESTAMPS Number of seconds since 12 a.m. Jan. 1,

1970 E.g. 5/3/2013 5:54:17 PM 1362518657.85

DESIGN: AUTO SHUTDOWN Problem 1: time is not a Unix timestamp ['11:20', ''] 1362063000.0

DESIGN: AUTO SHUTDOWN Solution: Step 1: Get the month, day, year

now

datetime.datetime.now()

month

day

year

str(now.month)

str(now.day)

str(now.year)

DESIGN: AUTO SHUTDOWN Step 2: Get the hour, minute, second hour,minute =

shutdownTimeList[0].split(‘:’) 11:20

hour = 11minute = 20

second = “00”

DESIGN: AUTO SHUTDOWN Step 3: Make a date string

e.g. mm/dd/YYYY HH:MM:SS Step 4: Make a timestamp Time.mktime.datetime.datetime.strptim

e(date_string, “%m/%d/%Y %H:%M:%S”)

e.g. 1362063000.0

DESIGN: AUTO LOGIN Threading abandoned Therefore:

shutdown –a: cancels shutdown/restart shutdown –r –t xxx: sets restart for xxx seconds

['1358517600000', '1358523000000', '1358527500000', '']

time.time()

os.system(“shutdown –r –t xxx”)

• clear any restart/shutdown• create 2 GB partition for H: • call login.vbs with

auto login credentials• call LibraryDefaultPage.vbs

DESIGN: AUTO LOGINnow restart 60 sec. after

auto login period

• clear any restart/shutdown• create 2 GB partition for H: • call login.vbs with

auto login credentials• call LibraryDefaultPage.vbs

os.system(“shutdown –a”)

subprocess.call(“diskpart /s command.txt”)shell.Run(“wscript.exe [file path]”)

DESIGN: AUTO LOGIN Problem: Multiple auto login times

Auto Login Start TimeAuto Login PeriodAuto Login End TimeOutside Auto Login Period

DESIGN: AUTO LOGIN Solution: Boolean flag

DESIGN: AUTO LOGIN Problem: auto login after auto shutdown

Auto Login Start TimeAuto Login PeriodAuto Login End TimeOutside Auto Login Period

DESIGN: AUTO LOGIN Solution: global variable

IMPLEMENTATION hour, minute =

shutdownTimes[0].split(':') dateString = month + "/" + day + "/" +

year + " " + hour + ":" + minute + ":" + second

time.mktime(datetime.datetime.strptime(dateString, "%m/%d/%Y %H:%M:%S").timetuple())
