title: keep track of richtext box text?
body: <p>I'm new to the VB applications.My basic background is C.I just installed VB and learning stuff from google and microsoft help center. and I'm having fun with the things I'm doing but I got stucked up at one point and thats at richtext box.Is there any way to keep track of Rich textbox text in VB? So that I can append some text when user hits new line (i.e enter ) and do some task when he hits backspace. How do i keep track of richtextbox.?</p>
  
  <p>I found </p>
  
  <pre><code>      stringer = RichTextBox1.Lines(0)  to read lines
        &amp; vbNewLine  for new line
  </code></pre>
  
  <p>How do i read that user hit the new line character or backspace in vb rich textbox? because as far in C i used to do like these</p>
  
  <pre><code>      if a = 13; \\ ascii for new line and 8 for backspace
  </code></pre>
  
  <p>I just want to do some task when user hits new line but I am unable to figure it out what the condition to be made.and  Any good links for vb and documents on VB or on its windows application would be appreciated Too. Thank you in advance </p>
