I'm using this with WEB Core. I set up two of these side-by-side with a splitter in between to show differences in a file.
I noticed that there's a way to highlight lines:
DiagCompare1_memo.LineHighlight[n] := True;
DiagCompare2_memo.LineHighlight[n] := True;
I made a change in the 2nd line of my data where 'n' = 1 (it was in a TWebMemo, and Lines is 0-based.)
I loaded the data into the FNC Memo, and nothing was added or missing. But with n=1, the FIRST line was highlighted, while the actual difference was in the SECOND line. I had to add one to n to get the correct line to highlight, suggesting that this Lines property is 1-based.
I also found that the highlight color is a dark red, and with black font, it's nearly impossible to read the text. I wanted to change the highlight color, but couldn't find any way to do it. Please add this.
