I agree with David that using GetTextExtent() would be the way to go. You
can change the font by setting the font for the control and resize the
control using either MoveWindow():

Or SetWindowPos():

When you create a font for the CEdit control make sure it exists for the
life of the control (like make it a member variable in the edit control
class).

You can use a function like:

http://msdn.microsoft.com/en-us/library/aa279839(VS.60).aspx

To create the font, but use a monospaced typestyle like "Courier" instead of
Arial (as David suggests).

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
Surjit

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.
