Sorry, what do you mean by replacing text part? If you want to copy document as a plain text (without all text and paragraph attributes, images, tables, etc.) use this code: var Stream: TStringStream; begin Stream := TStringStream.Create(''); RichViewEdit1.SaveTextToStream('', Stream, 80, False, Fal...

Yes, it does.
I opened access to the member section for your account.

Units DLines and CRVFData must still be added in "uses" of the unit where these functions are defined, otherwise the compiler will report error on lines with .Item2DrawItem and .Top. There is nothing wrong with using these units, they are already used by trichview code. Without the line rv...

Well, if you need I can post code for for fast splitting text item (not as an editing operation).

But all stored positions become invalid after editing...

uses CRVFData, DLines; procedure GetCaretY(rve: TCustomRichViewEdit): Integer; var DItemNo, DItemOffs, X, Y: Integer; begin rve := rve.TopLevelEditor; rve.RVData.Item2DrawItem(rve.CurItemNo, rve.OffsetInCurItem, DItemNo, DItemOffs); rve.RVData.GetOriginEx(X, Y); Result := rve.RVData.DrawItems[DItemN...

The method InsertCheckpoint inserts the checkpoint at the caret position. If it is in the middle of the item, the item will be splitted.

The methods GetFirstCheckpoint and GetNextCheckpoint allow to enumerate checkpoints without enumerating all items. But they ignore checkpoints in table cells.

The site moving procedure is started. After transferring is complete (1-2 days), I believe the site will be available in China.

May be it makes sense to mark these places with Checkpoints?

First, in trichview itself, these characters are not stored. They are converted to internal flag "this item starts a paragraph". As for using them in methods like InsertText or AddTextNL, it does not matter. TRichView understands line breaks defined as #13, or as #10, or as #13#10, or as #...

How do you fill this listbox initially? Do each paragraph in ScaleRichView correspond to one listbox item, or how?

RichViewEditIn.InsertText('This is line 1'#13'This is line 2', False);

Update 2017-Dec-4 ] TRichView setup now includes better version of this demo in <TRichViewDir>\ThirdParty\Export\LLPDFLib\Demos\RV2PDF\ folder. This better version reads all page properties from source RTF (or RVF) files and applies them to PDF, supports headers, footers, footnotes and endnotes, di...

I do not understand the first questions. All these lines (header, item text, image class, etc.) represents one item in RVF. The link for detailed RVF specification is http://www.trichview.com/help/index.html?rvf_specification.html If you use TMemoryStream, you can access data as Stream.Memory. The c...

You can do field replacement much faster without SearchText method.
See http://www.trichview.com/forums/viewtopic.php?t=8 , it had example with fields defined by {} characters.

Do you want to move caret to the specified Y position?
