title: How do I hide the input caret in a System.Windows.Forms.TextBox?
body: <p>I need to display a variable-length message and allow the text to be selectable. I have made the TextBox ReadOnly which does not allow the text to be edited, but the input caret is still shown. </p>
  
  <p>The blinking input caret is confusing. How do I hide it?</p>
