EM_FMTLINES Overview  Group

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.
