title: How to make an auto-complete textbox in a winforms desktop application
body: <p>I have a list of words. The list contains about 100-200 text strings (it's names of metro stations actually).</p>
  
  <p>I want to make an auto-complete textbox. For an example, user press 'N' letter, then an (ending of) appropriate option appear (only one option). The ending must be selected.</p>
  
  <p>How to do that?</p>
  
  <p>PS1: I guess, there is a textbox control with a Property something like this:</p>
  
  <pre><code>List&lt;string&gt; AppropriateOptions{/* ... */}
  </code></pre>
  
  <p>PS2: sorry for my english. If you didn't understand -> ask me and I will try to explain!</p>
