I'm trying to write a program that replies to user inputs with generic responses. I tried debugging it, but I can't figure out what's wrong.





    public partial class FormMain : Form

    {

        public FormMain()

        {

            InitializeComponent();

            ActiveControl = userInput;

        }



        public void userInput_TextChanged(object sender, EventArgs e)

        {



        }



        public void chatOutput_TextChanged(object sender, EventArgs e)

        {



        }



        public void btnSend_Click(object sender, EventArgs e)

        {

            SendMessage();

            ActiveControl = userInput;

        }



        public void SendMessage()

        {

            Process process = new Process();

            process.Processing();

        }

    }





    public class Process

    {

        FormMain main = new FormMain();

        Analyze analyze = new Analyze();



        public void Processing()

        {

            if (main.userInput.Lines.Length >= 1)

            {

                main.chatOutput.AppendText(main.userInput.Text);

                main.chatOutput.AppendText(Environment.NewLine);

            }

            main.userInput.Text = "";

        }

    }

We don't know either since you didn't say what the actual problem is.

Well that's not true... The issue is that you're checking a new instance rather than the one with the actual input. But in the future it might not be so obvious.

Sorry I'm still a bit new to programming. How can I reference userInput so I can use it instead of creating a new instance of it?

Something like:

[source lang="csharp"]
public void SendMessage()
{
this.chatOutput.AppendText(Process.UserInput(this.userInput.Text));
this.userInput.Text = string.Empty;
}

public static class Process
{
private static Analyze analyze = new Analyze();

public static string UserInput(string input)
{
return input;
}
}
[/source]

How can I use userInput in my Analyze class so I can see if userInput contains certain text?
I have something like this:



        FormMain main;



        public void Analysis()

        {

            if (main.userInput.Text.Contains("asdf"))

            {



            }

        }

But how can I reference userInput then analyze it and then modify chatOutput?

Something like that, but the errors you're making show a fundamental lack of understanding about how objects are instantiated. Don't try to do too much. I can't help too much without giving code essentially to copy. You need to learn how to construct your program to do what you need.
