Question

I’ve been searching the reason why the maximum length of String in a TMemo.Lines is 1024, but not found yet.

I have a text file which contains delimited / csv data which length is around 2000 characters.
I use a memo to preview it before I process the file.

memo.Lines.LoadFromFile(textFile);

I have set the WordWrap to FALSE, and scrollBar to ssHorizontal. So any record will not be wrapped to the next line.

But when I iterate the memo.Lines, I found that the maximum String hold in each index is 1KB or 1024 characters. The rest is truncated to the next line.

But if I use TStringList to load the file, the row is not truncated to the next index when it reaches more than 1024 characters. This is not happen when I use TRichEdit.

1. Anyone can explain this phenomena?
2. Is it the default behavior of TMemo?

I use D2006 to try this.

As the great Peter Below says :

…This has nothing to do with the
appearend line length limit. This
limit is really just visual, caused by
the way the control renders its text.
