    read your help files or refer to msdn for examples on creating a window. Store lines in a linked list. Again refer to msdn for information on trapping keyboard messages. See what you can come up with some research. Post some code of your own if you want further help.
    Free the weed!! Class B to class C is not good enough!!
    And the FAQ is here :- http://faq.cprogramming.com/cgi-bin/smartfaq.cgi

    hm... you could just place a CEdit element on the window.
    You wouldn't have to do anything yourself.

    It's very hard for us to guess what you already know, or
    how you want to do this, as there are many different ways.
    So if you could provide us with an example of what you did
    so far, I'm sure we can show you how to proceed.

    She was so Blonde, she spent 20 minutes looking at the orange juice can because it said "Concentrate."

    When in doubt, read the FAQ.
    Then ask a smart question.

    I don't quite get what you want, but you could try the following:

    you can poll any key (check if it's pressed or not) using the following fuction:

    SHORT GetKeyState(int nVirtKey);

    where nVirtKey is the virtual key code of the key you want to poll, you can replace it with

    VK_LEFT
    VK_RIGHT
    VK_UP
    VK_DOWN
    VK_BACK_SPACE
    VK_HOME
    VK_END
    VK_DELETE

    check the high order bit, if it's 1, the key is pressed.

    if you don't know how to check the high order bit, you can do it with a function like this:

    int CheckHighBit(SHORT c)
    {
    SHORT mask=(0 (1<<(sizeof(SHORT)-1)));
    if(c & mask)
    {
    return 1; //The high bit is on (The key is pressed)
    }
    else
    {
    return 0;
    }
    }


    good luck
