hi everyone...
i needed to make a script that could DISALLOW the "users" to operate computer more than 10 Minutes each day until a specific day.so after thinking alot i made a "freaky style" script... but am having some problem... THis part checks constantly for any CHANGES in the time (minutes)... and if it sees any .. it reverses the settings back to last SAVED:

[Laszlo]

Have you thought about the following approach?
- Start the script when the PC boots
- Save the time A_Now
- Check periodically (once a second) if the saved time + A_TickCount agrees with the date/time setting of the computer (within one second). If not, set the time back to what it has to be, and give the warning. This way you can trust the PC time. And using TickCount avoids the problem when the minute value wraps.

You will have problems at daylight saving changes and when the user really needs to adjust time. From the task list you could kill the script and make the changes. Hopefully, normal users won't know how to kill a task. Otherwise, you cannot do anything.

thanks Laszlo
i tried your approach.. but it doesnt work... maybe cause the A_TickCount is in float... and when i change it to seconds by dividing it to 1000 ...it always gives decimal places with it... and when compared with A_Now its always different...and let me tell you whole of my script... its purpose is to Stop every User (Every USER including ME) to use the Computer for more than 10 minutes a day ... and when June 8th comes.. this script must disable itsefl .,. and remove itself from registry/startup (computer back to normal)... now i know it sounds crazy to make a script that can DISALLOW/Stop everyone INCLUDING ITS PROGRAMMER to Alter its state by ANY MEANS (the 10 minute period is SPECIFIC from 1:05 to 1:15).. so to do that i made the script with these capabilities:
- After it will be complete... Once its RUN . It will Add itself to Startup
- It will Close INSTANTLY any windows that MUST BE USED to KILL IT (System Configuration, Task Manager etc)
- If it detects any change in Hour/Date/Month settings of the pc ... it reverts them (and those parts are working fine except for the MINUTE one)
- Every it exists.. it saves ALL TIME INFO (date, month, hour, TIME COMPUTER WAS USED) to a TXT file and then it COMPILES itself alongwith the FILE
- (In Case of if someone changed the date to June 8th i added this: )every time the window runs again it opens its EXE file (Obviously cause it is run through that exe) and extracts the TXT file and see's the Difference between the previous Date and todays date and if the difference is more than one DAY it sets the date back to previous(the computer is supposed to run everyday)
- and some more things and info... which i am leaving..
so U must be annoyed right now... but i am like that .. so Really sorry about that... anyways... so can you tell me how to Fix the Minute Problem PLEASE (And if you can give any other tips TOO)..sorry again Buddy for disturbing too much

You can use Transform Round to make the result integer:

Let's fix the time-check routine first. Because of the freaking Greek, we have base 60 and 24 number systems with time (sec, min; hour), so we cannot just add a number to a time value, but have to check if it became larger than allowed, and propagate a carry if it did. What I meant in my previous post is described in the following script.

[Laszlo]

The next problem is using third party utilities, like Startup Inspector for Windows. It can prevent loading any program started from the Startup folder or from the registry. We have to add another timer routine, which checks periodically if the startup entry has been removed, and add it back.

Other type of utilities, like Sysinternals' Process Explorer, can kill any process, including AHK. Closing the Windows Task Manger from the script works surprisingly well. (I was not able to change or remove the title of its window and so I could not prevent it be closed – maybe someone succeeds. Anybody to give it a try?) But what can we do about other utilities?

Maybe we have to imitate a virus: attach the AHK script to an important Windows file, which cannot be killed without crippling Windows. This would also help against booting into safe mode and removing the script.

But what happens if Microsoft releases an update, which replaces the file? Anyone has an idea how to attach automatically back our script?

[Laszlo]

Just collecting ideas. Do you have any suggestions, which could work? If a user can remove the restrictions easily, why bother writing those tamper resistant SW.

hi
thanks Laszlo
it works...(i just copy pasted it .. have to see what its doing:))
anyways..
the problem is that it keeps giving the message even if the time has been reversed (i did it manually..not through giving it a subroutine to change the time through cmd... and what about backup variables? :S (the Yday cant be used to set the month and the day of the month etc)...
anyways..i am going to read it it now..and see where to modify it (until then if u read this .. please reply)
thanks
(and we might not wanna go too far... but still i'll sendsome info onthis topic on how to make it (even securer) BUT AFTER 8th JUNE )
*nothing is useless
and other than that i took it as a challenge (but u r right corrupt... cause u r not gonna find many psychos like me )

hey Laszlo
u used functions in ur script ? :S (actually i've never used them before.. and saw them for the first time in a script.. )

Actually, the script can be simplified using AHK's time manipulations:

You can disable the Task Manager via the registry, and its also possible to disable editing the registry too.

(I was the last Guest with the simplifications, just forgot to log in.) I tried setting the date and time from an AHK script. I am stuck. Setting the date works perfectly with
