Topic: How can I copy one line of RichEdit component

Please, anyone can give me advice on how to make a copy full of one first line of RichEdit component to TextBox?
For example, here I can Copy 30 letters of the first line but not a full line.

frmNewNote.EdTitle.Text := Copy(frmNewNote.RichEdit1.Text,0,30);    ///Copy 30 letters

What I should change in my script? Thank you very much in advance

Re: How can I copy one line of RichEdit component

Clarification required. If you want to copy a line that ends with a CR, then it is possible: just find the position of this character and copy the fragment. 


copy( Form3.RichEdit1.Text, 1, pos(chr(13), Form3.RichEdit1.Text ))

But if we are talking about the displayed line, which was formed as a result of the text wrapping algorithm, then nothing will come of it.
