Unless you have a fixed-pitch font, you must set the width for the widest
possible line
you might get. Typically, in the Roman alphabet, this would be the width
of 70 W
characters, but for other fonts, Your Mileage Will Definitely Vary; for
example, in some
languages three "characters" might actually overlap each other. This gets
into deep
complexities.
Or, you can dynamically resize it on the fly, although I would think this
might be
visually disturbing if the user typed in 70 letter i characters on one
line, then 70 A
characters on the second line, and 70 W characters on the third line. But
there is NO WAY
to predict how wide "70 characters" is going to be in a variable-pitch
font! So either
you keep doing dynamic adjustments or you size to
maximum-possible-worst-case.

Hello,
Thank you for replying to the post.
but my actual query is to 'I want to set the width of this cedit control
and correspondingly update the width of parent dialog and the 2 buttons.
based on the number of characters i want to in each line' , I believe this
approach might be helpful as my cedit control is multiline, and horizontal
scroll is disabled. and cedit will automatically take care of max text
when user has reached the width end.
Only logic needed here is to calculate the width based on characters and
font size of the system and correspondingly resize the cedit and parent
dialog
Thanks and Regards

Ah I misread the question. Thanks for the clarification. I guess I did
not
think that someone would want to limit the characters to the length of the
box showing so I just read the 70 and went with that. You are right that
a
lot depends on the character font, size, etc. which is often changeable by
the user if the programmer does not force it. I have often resized
controls to
fit the screen or limited the number of characters (of any type or size),
but never tried to fit it to what is only showing on the screen so I just
did not think of that.
I think you are right. This is a more difficult design challenge than I
originally thought and I do not think the designers of Window or MFC
thought
about this eventuality.
