Console events...?!

I posted this topic regarding the same problem. Now I am trying to do it in C#, but cannot get much further!

The thing is that I would like to have a console dialog, in which the dialog continues after only one key press, and not after a whole string has been entered and the 'Enter' key has been pressed. Is this possible and how?

Thanks

Jacob.

Not to split hairs but here you speak of a 'console dialog'. But in [u]your</u> other posting your code sample was:

Code:

String s;
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
while(true)
{
    showDialog(); 
    s = br.readLine();
    switch(s.charAt(0))
    {
        case '1':

A console dialog, to me, says you have created a console app but your Java code says you are creating a dialog window yourself. Assuming the latter have you considered replacing your Readline() approach, which requires an Enter with a method within your dialog that monitors the keyboard for the press of a key and exits the dialog when the appropriate ones are pressed:

Code:

protected override void OnKeyDown(KeyEventArgs keyg) {
   switch(keyg.KeyData) {
      case Keys.1:
         //...   processing - send event/keycode to parent window & exit?
   }
}

OK, sorry... I may have been unclear on this. I am not doing a windowed dialog in Java. I didn't show the showDialog method since it is irrelevant for the problem; I thought. The showDialog only shows some lines of text output on the standard out stream!

Code:

    public static void showDialog()
    {
        System.out.println("Choose one of the following options...\n");
 
        System.out.println("1. Make new user");
        ...
        System.out.println("7. Identify user");
        System.out.println("9. Exit");

        System.out.println();
        System.out.print("Enter option number: ");
    }
}

I will tell you the full story! The thing is that I am currently working on a small project where I am trying to identify users from the way they press the keyboard. For this I am using a program called xlisten, and which runs on Linux. I pipe the output from xlisten into my Java program so I can analyze the xlisten output! Part of the Java program require the user to enter som data from which typing patterns are retrieved, and this is why I use a console dialog etc.

By the way... The reason for my C# question was that I am primerily a Windows user, so I am mostly developing on this platform, and some C# help might have helped me!

Thanks anyway.
