[C#] Weird RTB Problem

[Nuklear]

I have a problem. This worked for me all the time, but not this time I really don't know why. I tried experimenting with it and no luck.

public void AddLine(Font font, Color color, string text, bool Timestamp)
        {
            logbox.SelectionColor = color;
            logbox.SelectionFont = font;
            string timestamp = "";
            if (Timestamp)
                timestamp = "[" + DateTime.Now.Hour.ToString() + ":" + DateTime.Now.Minute.ToString() + ":" + DateTime.Now.Second.ToString() + ":" + DateTime.Now.Millisecond.ToString() + "] ";
            logbox.AppendText(timestamp + text);
            logbox.SelectionColor = Color.Black;
            logbox.SelectionFont = enhance;
        }

That's my log code for a richtextbox. It works, but I can't make it work when it's called outside of a class. I even tried using static, and putting in Form1 frm = new Form1(); and replaced logbox with frm.logbox

It doesn't even append any text to the rtb. I even tried changing the rtb's modifier to public.

No error messages are produced and do anyone know why?

Did I delete your msn ?

Anyway, you have to supply more code, as in:

Full class
Class it's called from
Threading information (if any)

And define precisely what is NOT working.

possible that you are trying to do this across 2 threads? that would be a problem

The problem is that when I call this function, nothing happens.

Provide more code. What you have given is not enough to get an answer.

If you have

public class Foo
{
  private object logbox;

  // Some code here (logbox can't be null when AddLine is called)

  public void AddLine(Font font, Color color, string text, bool Timestamp)
  {
    // Some code here that uses logbox
  }
}

Then you should be able to call

Foo foo = new Foo( ... );
foo.AddLine(somefont, somecolor, "Some Text", true);

And it should do something.

Make sure you are not swallowing up any exceptions thrown with an empty catch block.
