title: Drawing a blinking caret in Winforms
body: <p>I'm developing a custom control, which most resembles a text area. I am drawing text, which works correctly, and accepting input which also works.. But I (the user) am left guessing where the caret is while I type, since I'm doing everything manually.
  How do I draw a blinking caret to show where I am currently typing? Is there a standard way to do this?</p>
