An application may direct a multiline edit control to add or remove a soft linebreak character — two carriage returns and a linefeed — automatically at the end of wrapped text lines. An application can turn this feature on or off by sending the edit control an EM_FMTLINES message. This message applies only to multiline edit controls and does not affect a line that ends with a hard linebreak — one carriage return and a linefeed typed by the user.
