Well, before even going into the details, can you tell us why do you whant to do that? May be a alternative/simpler approach can help you.

I have 1 problem and i want to learn how to do that :(

[Manas Bhardwaj]

This might give you a little idea:

private void richTextBox1_MouseHover(object sender, EventArgs e)
{
Point _location = richTextBox1.GetPositionFromCharIndex(richTextBox1.Text.Length - 1);
MessageBox.Show(string.Format("{0}, {1}",
_location.X,
_location.Y));
}

Something like this would work but I doubt it is the best way to do it....

    private void richTextBox1\_KeyUp(object sender, KeyEventArgs e)
    {
        int totalLength = 0;
        int line = 0;
        int pos = 0;
        for (int i = 0; i < richTextBox1.Lines.Length; i++)
        {
            if(i != 0) totalLength++;
            totalLength += richTextBox1.Lines\[i\].Length;
            if (totalLength >= richTextBox1.SelectionStart)
            {
                line = i + 1;
                pos = richTextBox1.SelectionStart - (totalLength - richTextBox1.Lines\[i\].Length);
                break;
            }
        }
        label1.Text = "Line " + line.ToString() + "; Char " + pos.ToString();
    }

Hi, I haven't used it myself (I don't like RTB that much) but this looks like the right tool[^] for you. :)
