16.2.3..Multiline Edit Boxes...........................................................................

By default, an edit box is used to display a single line of text. An edit box is referred to as

multiline when it can display its text on more than one line.

To create a multiline edit box, use the same Edit control as the above single line Edit box.

To make this a multiline edit box, set its Multiline property to True. To do this at run

time, add the ES_MULTILINE style to the CEdit. At design time, to make it obvious

that the control can display more than one line of text, heighten it:

If the user is typing text in an edit control and press Enter, the control, usually a button,

that is the default would be activated. This feature is valuable for a single line edit box. If

you are creating a multiline edit box, you should allow the user to press Enter while

entering text into the control. This would prevent the default button from being activated

and would transfer the caret to the next line. To provide this functionality, add the

ES_WANTRETURN style or, at design time, set the Want Return property to True.

If the text of the edit control is longer than the edit control can display at one time, you

should equip it with scroll bars. To do this, at design time, set the Horizontal and/or the

Vertical Scroll properties to True. At run time, add the WS_HSCROLL and/or the

WS_VSCROLL properties.
