Actually, it's not very difficult. It was not implemented only because in TRichView checkpoint may appear only as a result of scrolling or resizing (and resizing usually causes scrolling), but in TRichViewEdit it may also appear as a result of editing. So the code used in TRichView will not always ...

Do you use RichViewXML to store XML data?
Please send me this XML doc.

No, not in near future.
You can try to implement it yourself - in OnVScrolled and OnChange events, check items starting from FirstItemVisible, using GetItemCheckpoint.

Not yet, but this will be the next feature to implement.

How the text was created initially? Loaded from file?

In your code, I do not understand the statement Why do you need to process the last item specially? This item is not necessary starts a paragraph.

Sorry, what do you think IsFromNewLine means? Probably, you misunderstand it, and so there is a confusion.

Actually, it means "this item starts a paragraph" (or a line inside paragraph, added with Shift+Enter).
In your example, there are 2 paragraphs, so there are must be only 2 items having ...

I created an ActiveX, and I can confirm the problem. Unfortunately, it's difficult to debug ActiveX, so it may take some time.

Sorry, I do not understand what's wrong.
In your example:
Item[0] = 'LETHAL' IsFromNewLine = True , because the document starts from a new line, IsFromNewLine(0) is always true.
Item[1] = character IsFromNewLine = False , because the character contunues the same paragraph as the previous item ...

Sorry, do you need to implement this as an editing operation (that can be undone by user) or not?
For an editing operation, your code is correct: select the proper cells and call ApplyParaStyleConversion.

1) About pasting from web pages. Which browser do you use, and which web page do you copy?

2) About copying to email composers.That means that Outlook Express ignores images in pasted RTF content, and Thunderbird email composer does not paste RTF at all (pastes plain text). There is nothing I can ...

If there are two paragraph, each containing 1 item, both IsFromNewLine(0) and IsFromNewLine(1) are True.
text := '';
for i := 0 to Editor.ItemCount-1 do
begin
if (i>0) and Editor.IsFromNewLine(i) then
text := text + #13#10;
if Editor.GetItemStyle(i)=rvsTab then
text := text + #9
else if ...

IsFromNewLine(0) is always true (because any document starts from a new line). If you use your own function getting text from RichView, do not add #13#10 for the 0th item.

There are several possible reasons why images are not inserted.
1) Images have formats unsupported by Delphi by default, for example gif and png. You need to use thirdparty graphic classes to support them (see http://www.trichview.com/forums/viewtopic.php?t=89)
2) Images are on a web server. They ...
