Winforms: Screen Location of Caret Position

How can I find the screen position of the caret for a standard Winforms TextBox?

From stackoverflow

• You can do it only with native interop: GetCaretPos

  [DllImport("user32.dll")]
  [return: MarshalAs(UnmanagedType.Bool)]
  static extern bool GetCaretPos(out Point lpPoint);
  

  bbqfrito : Worked like a charm. Thanks!

• I have been using the TextBox.GetPositionFromCharIndex function. It gives coordinates relative to the top left of the the TextBox.
