Does anyone know how to get the line number that the currsor is on in a TRichEdit.  In a TMemo you can do a
iLine := Memo1.Perform(em_LineFromChar, $FFFF, 0);
but the RichEdit will always return the total number of lines instead of the current line.  
Thanks

Hi Greedy,

Try:

     iLine := RichEdit1.Perform(em_LineFromChar,-1, 0);

It worked fine to me.

Cool...that works, The reason I want the current line is so I can indent the line (paragraph) with the \li tag but how can I tell if this line is actually part of a paragraph.  Currently I have to open the file as a File of Char and then parse backwords until I hit a \li and if that line doesn't already have a \li then I have to go until I hit a \par  or a } plus I have to account for the posibility that the user has actually typed in \par or something so I have to look if the \ isn't really a \\ this is really a pain to have to code so much low level parsing plus doing the insert of the \li and then redisplaying it will get really slow on a big file.  The current input into these RichEdits is only about 5 lines so it's no big deal now but I was wondering how I could speed this up.  If there was a easy way to get all the text that is associated with a paragraph (every thing between one \par and the next) then I could do this parse really fast and insert it back without haveing to close the file, rewrite it and then load it again.
Thanks...

Well,  after a bit of a total crap day tring to do low level formating of this file I decided to just use the WPTools that I got with LMD component kit.  Well worth the $120 bucks now that I have figured out how to work them.  Thanks, I'll give you the points because you did after all answer the question that I asked...
Thanks again.
