    Unhappy Activity timer with RS232 out

    Hello everyone
    i'm looking for help on writing C program that when started, it's counting time (like 10 seconds) and when any key is pressed (shoul'd be any key - all keys), start to count again. when the timer reached the 10 seconds and no key is pressed, the program send out data via the serial port (rs232) or even a beep to the speaker.

    any help will be appreciate

    TNX

    Thanks for answering so fast...
    i learned C many years ago, so i don't remember even where to begin...
    the real help i need is that someone will write the code for me. i belive that if i need to change something later i will manage by myself, but if not - you are here...

    Due to all of the homework-related requests on these kinds of sites, you will generally not get help here until you help yourself first.

    If it is not homework, what is it? What do you need it for? Maybe there's a freely available program to solve your problem. For instance, depending on your purpose, a keylogger might be what you need.

    Hey, I wish i coul'd help... i don't know much and what i did learned i forgot !
    it's not homework. i need it for triggering an alarm when the computer (user) stop typing after a certain time. i need it for a test i'm doing at my work. (not C programming related...)

    i just thought that for you guys is a five minutes work... i thought that's what forums all about, helping others.
    Thanks

    It is. That's why we're not just posting a solution.

    So, where is the user typing into? Is it "any" application, or a very particular application? What OS is this running on? Does it need to be tamper proof, or just "work most of the time"?

    The solution is different if the user has to type into a particular application.

    And by the way, what's going to prevent the user from putting a weight of some sort on the spacebar to make it seem like the user is typing?

    When it comes to "Helping others", the best help is usually to help others to understand, not to help them do it for them. Do you think my 3.5year old son prefers me dressing him or him doing it himself? Which is best for him later in life?

    If you want someone to professionally do this for you, pay for it.

    I believe the pair of bowls is ' Give a man a fish, you feed him for a day, Teach a man to fish and you feed him for a lifetime'. or in cynical terms, 'Give a man a fish and you lose a sale, Teach a man to fish and you lose a customer'.
