Actually I set the size of the form, and the RichEdit is alClient. First I get the number of lines (MyRichEdit.Lines.Count), and calculate a suitable width. I enlarge the form width appropriately. Then I get the number of lines again to calculate the height I need for the form. The number or lines, of course, has decrease because the control is wider. However, I still get the original number of lines from MyRichEdit.Lines.Count. Even if I clear the control and reassign the text. What do I need to do to get the correct number of lines for my height calculation? Or is there another way to determine the height of all the text? Note that the text never contains CR or LF.

Just handle the OnResizeRequest event, it tells you how high the control needs to be. -- Peter Below (TeamB) Use the newsgroup archives : http://www.mers.com/searchsite.html http://www.tamaracka.com/search.htm http://groups.google.com http://www.prolix.be Back to top Jon Jacobs Guest Posted: Sat Oct 25, 2003 2:26 am    Post subject: Re: Sizing a RichEdit Thank you, Jon "Peter Below (TeamB)" <100113.1101 (AT) compuXXserve (DOT) com> wrote Quote: In article <3f9841b1$1 (AT) newsgroups (DOT) borland.com>, Jon Jacobs wrote: I need to set the size of a RichEdit so that it is just large enough not to need scroll bars, unless the size reaches a predetermined max.
