From: surjit on 7 Jan 2010 00:13 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 Tom Serface wrote: Ah I misread the question. Thanks for the clarification. 06-Jan-10 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.

You need to use a fixed spaced font (like Courier New) so that each character takes the same width as any other. Otherwise, in proportional spaced fonts, characters like '1' take less space than fat characters like '8'. You can use the SetFont() method to set a proportional spaced font. -- David
From: Tom Serface on 7 Jan 2010 02:28 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(): http://msdn.microsoft.com/en-us/library/5bc5w1zz(VS.80).aspx Or SetWindowPos(): http://msdn.microsoft.com/en-us/library/a1yzfz6d(VS.80).aspx 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).

From: Joseph M. Newcomer on 7 Jan 2010 10:47 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. joe On Wed, 06 Jan 2010 21:13:33 -0800, surjit bawa wrote: >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 > > > > >Tom Serface wrote: > >Ah I misread the question.

Yikes, resizing the control as the person types would be a nightmare and a lot more ugly than a monospaced font. Tom "Joseph M.
