[algogeeks] Re: Code to stop students from navigating during online examination
This is not an algorithm question. I suggest announcing that any student who uses any electronic device to do anything other than take the test will fail the class.

i agree it can be done but like in company training and GATE exam and even certification exams when the test starts everything else gets disabled till student either clicks QUIT TEST or time is over till then everything is limited to that screen a feature very common after 2006 to avoid cheating...the program goes to full screen mode and can't be minimized On Fri, Feb 24, 2012 at 7:27 PM, Don dondod...@gmail.com wrote: This is not an algorithm question.

[algogeeks] Re: Code to stop students from navigating during online examination
Yes, that would be a good thing to have. It's still not an algorithm question. It depends on the OS and the specific tools you are using. If it provides a full screen mode, use it. Without knowing more there's not much else we can tell you. And if someone has a smart phone or even a basic cell phone which can send and receive text messages there is still the potential to cheat.

Re: [algogeeks] Re: Code it...
I am not sure about the program to do it. But, 'strace' on linux would give the details of a program(parameters passed, retrun values, signals recieved etc). If you are looking for something similar then you can loot at strace source. mean while a.out does not not have information of stack pointer etc which will be built only at run time and it just tells what data goes to text, stack etc. it is dumb it does not do anything, the interpreter recollects all the info from a.out. - Azhar.

[algogeeks] Re: Code it...
It depends on the language. If is is a scripted or interpreted language then you can just change the source code. If it is a compiled language you would change the binary code where the output value is stored. I'm not saying that it is a recommended approach, but it is possible.

[algogeeks] Re: Code it...
Not really. Most executable formats have a way to include extra data that's not used by the loader. You could store a count in such data and have the program modify the executable every time it runs. Not recommended, though. A separate file is a much better idea. You could also play games by actually changing the BSS area (or equivalent) of the executable. You must assume the binary isn't compressed or encyrpted in any manner (a big assumption), then do something very ugly like: char magic[256] = run number is here --00; then open the program's own executable (argv[0] is helpful for this) in read-write mode, scan it to find the string run number is here -- , print the count stored after it, then write back the same bytes after incrementing the number. Back in the day this kind of trick was used for various things like copy protection. Today it's likely to cause some security program or the OS to get very upset. (Some OS's lock the executable of a running program (for paging purposes), so this won't work at all.)

[algogeeks] Re: Code it...
the only way to do this is to store in an external space like file. if its a function that is called, a static variable can be used to track count. Question: Can extern variables span accross processes? They cannot right. I mean two forked process share the same extern variable instance?? -- You received this message because you are subscribed to the Google Groups Algorithm Geeks group.
