Change TEXT color on line X in TrichEdit
I run Delphi 7 on XP sp3.
In my TrichEdit I have N lines like this:
TextLine 1
TextLine 2
..
TextLine N
...
If, for some reason the an error ocur, and the text changes to:
TextLine 1
TextLine 2
TextLine 2 (mark // my marking)
..
TextLine N
I want the first duplicate (= second line Textline 2 (mark) ) marked as RED.
I have tried to :
Text := RichEdit.Lines[second Textline 2];
Richedit.SelAttributes.Color := clRed;
RichEdit.SelText := Text;
It works but places the Text at the beginning (topline in the RichEdit).
I see the problem as moving the RichEdit-lineCounter to line (testline 2 (mark)) or something similar, but how do I do that (= mark the error-line in RED ) ?

You have to do this following:
- Find the character index of the first character whose formatting you want to change, and set
SelStartto that index. - Set
SelLengthto be the length of the text that you wish to format. - Modify
SelAttributesto apply the desired formatting.

See theEM_LINEINDEXandEM_LINELENGTHmessages (note, there is a typo in the latter doc. "This parameter can be 1" should say "This parameter can be -1" instead).
