title: getting current line text is on
body: <p>I have a list of lines that looks like this:</p>
  
  <pre><code>textbox.text += "p"+b+" the rest\r\np"+b+" more text";
  </code></pre>
  
  <p>b is supposed to represent the current line number in the textbox that the line is on. I have tried using textbox.lines.count() but it only changes i into the last line number. </p>
  
  <p>Is there any other way about going with this, or do I have to switch to another method?</p>
