title: Autocomplete [contains instead of starting with] in winform TextBox
body: <pre><code>// [in designer] textBoxInContext.AutoCompleteMode = Suggest
  // [in designer] textBoxInContext.AutoCompleteSource = CustomSource
  AutoCompleteStringCollection autoComplete = new AutoCompleteStringCollection();
  autoComplete.AddRange(myArrayofStrings);
  textBoxInContext.AutoCompleteCustomSource = autoComplete;
  </code></pre>
  
  <p>I have this code which works well as documented in MSDN. <br/> <br/> Problem: if user types "PS" it shows all the string starting with "PS"; I would like to display all the strings containing "PS"</p>
  
  <p>Any pointers ?</p>
