Re: [Tutor] How would I make a program that password protects on aninactivity timer?
> (This is on Windows, on something called novell, > or something close which acts as a logon service) Hmm, Novell, the second biggest networking company in the world might not be too pleased with that description... :-) Novell provides a comprehensive network resource and inventory management service as well as a directory service and shared storage and alarm management. If you are not on Win2K or XP its probably pretty fundamental to your entire network operation. It also provides logon services including such features as password history protection, password timeouts, password composition rules etc. But it primarily operates at the network level, it will prevent you accessing the network rather than the PC (although it can do the latter if you have the appropriate client installed). > I noticed that there's no way to activate password > protection on inactivity, or no way to secure the > computer at all without logging off This will depend on the OS. If it is Windows NT, Win 2000 or XP you can do a lot of this from Windows. On older Windows versions the protection is still there but not as strong. Simply activate the Screen saver and set up a password. > creating a program, that ran a timer that reset > when you move the mouse or hit a key, This is possible by detecting Windows events and resetting the time, but its not that easy and not really necessary.

Hi Conrad, Welcome to the tutor list. >I am just wondering if I would be able to hire a tutor to learn >Python or We come free. > not, I know there is a tutorial, but I dont seem to be learning > throught > tuturials, OK, The way this list works is you pick one (or more!) tutorials and try to work through them. When you hit something you don't understand you ask a question on the list and whoever thinks they know the answer will send a reply. The questions can be specific to code: "here's what I wrote but it doesn't work - Here is the error message I got" - it's very important to include the error messages! or conceptual, eg: "I don't understand how parameters work with functions..." > my questions is there any tutors Online This list operates online only > i reside in Canada , Ontario , Brampton.

I always to do it the the hard way :-) Using ideas from eariler posts (regarding Windows events and ctypes), here's my attempt. Warning: This is an initial start that you can fix-up and build upon. Suggestions welcome. Bill """ Locks a Windows WorkStation if a user is idle for a specific amount of time. My definition of idle is: 1). No keys have been pressed. 2). The mouse has not been moved. To run this, you will need to install: pywin32 -> http://sourceforge.net/projects/pywin32/ ctypes -> http://sourceforge.net/projects/ctypes/ pyHook -> http://www.cs.unc.edu/Research/assist/developer.shtml This works for me on Windows 2000 Pro SP4 using: Python 2.4.3 pywin32 Build 208 ctypes-0.9.6 pyHook-1.4 Things that should probably be fixed: 1). This only runs once. When we hit the limit in idleTimer(), we break out of the loop and never go back. Ideally, it should reset / restart when we logon again... 2). Do we need a method to stop the message pump? Right now, it just runs indefinitely.

[Tutor] Unicode problems
I've been having unicode problems in python on Mac OS 10.4.

UnicodeEncodeError: 'ascii' codec can't encode character u'\xf1' in position 5: ordinal not in range(128) >>> As I understand it, that should work. I tried using different character sets (like latin-1, etc), but none of them work. The main problem I am having is in getting python not to give an error when it encounters a sterling currency sign (£, pound sign here in UK), which I suspect might be some wider problem on the mac as when I type that character in the terminal it shows a # (but in Python it shows a £).
