An application sends an EM_FMTLINES message to set the inclusion flag of soft linebreak characters on or off within a multiline edit control. A soft linebreak consists of two carriage returns and a linefeed and is inserted at the end of a line that is broken because of wordwrapping.
EM_FMTLINES
wParam = (WPARAM) (BOOL) fAddEOL; // linebreak flag
lParam = 0; // not used; must be zero
Parameters
fAddEOL
Value of wParam. Specifies whether soft-linebreak characters are to be inserted. A value of TRUE inserts the characters; a value of FALSE removes them.
Return Values
The return value is identical to the fAddEOL parameter.
Remarks
This message affects only the buffer returned by the EM_GETHANDLE message and the text returned by the WM_GETTEXT message. It has no effect on the display of the text within the edit control.
The EM_FMTLINES message does not affect a line that ends with a hard linebreak. A hard linebreak consists of one carriage return and a linefeed.
Note that the size of the text changes when this message is processed.
