    Auto Complete ?

    Hi all,
    I am doing a router simulator. and my programming skill is consider the basic of the basic
    I am just wondering, could anyone show me how do i do this,

    on line 1 of the console, i enter "ena"
    on line 1 of the console, i press tab button
    on line 1 of the console, the "ena" become "enable"
    text could still be enter after the enable and the story go on and on ...

    is there a way to do this in C/C++ or had to use MFC ???

    Thanks

    Read each keystroke. If tab is entered, search your list of commands for the current buffer. If there is a match, subsitute it for the command. If there is more than one match, subsitute the first. If tab is pressed again, subsitute the second. And so on.

    So all you need to do is:

    1) Have a list of commands.
    2) Read each keystroke as your input loop.
    3) Process input accordingly.

    it is something like the DOS/ UNIX-BASH auto complete. It help you complete the filename.
    let say in red-hat,
    i type adsl-set, press tab, it add "up" to "adsl-set", making it "adsl-setup".
    it is something like that ...

    thanks

    I think you need to be concentrating on the "I am doing a router simulator" part of the problem before wasting a lot of time on making the user interface just a bit more glossy than necessary.

    A program which does routing simulation with the minor inconvenience of having to type "enable" in full is far more preferable than a program which auto completes "ena" to "enable" and then fails to do anything.

    That is what i think, but then our ~!@#$%^&*( lecturer need us to include this function in it ....
    this is going to be a long long task ....

    Use strncmp() to compare the N letters you've typed in so far with an array of complete words which match your commands.
    If that results in a unique match, you can complete the command

    the problem is i do not have problem dealing with strncmp, however i did have problem dealing with how do i get the input from the buffer directly without pressing tab. i had look at the example in the faqs, but i still can not figure out... what function should i use on this? getchar or getch??

    What you want to do is entirely OS dependant. There is no standard way to read a keystroke, which is what you need to do. Thus, you'll have to use something like the curses library, if you're using a *nix variant, or some of the old dos routines if you're using DOS, or some of the Windows API functions if you're programming for windows, or ... You see the problem?
