The problem still exists.
Please check your email for more detailed explanation and demo file.
rvActionsDemo raises error opening that file.
But my old EXE with RVE v.10 or v.11 compiled under D2007 works fine.

Any suggestions on how to scroll by line?

I cannot assign TIcon to TPNGImage.
This will not work:
PNGImage.Assign(TIcon)

but this will:
PNGImage.Assign(TBitmap)

But using bitmap loses transparency

Found a code inside PNGComponents on how to convert ICO to PNG...it's a big procedure. Should be easier for D2009/2010

Ok, thanks. It's working now.
Had to put some other checks to avoid selection bounds errors but now it works.

It worked before like a charm. Never got any errors.
So where I should move it? Where is better?

Commented UpdateEditorUI and got just one AccessViolation here (not infinite access violation loop as in the first case): procedure TCustomRVFormattedData.Item2DrawItem(ItemNo, ItemOffs: Integer; var DrawItemNo, DrawItemOffs: Integer); var item: TCustomRVItemInfo; i: Integer; begin DrawItemNo := -1;...

It happens when undo action moves cursor from one cell to another. I have this OnCaretMove implementation: procedure TMainForm.RichViewEdit1CaretMove(Sender: TObject); var line,linescount,col:Integer; begin UpdateEditorUI; RichViewEdit1.GetCurrentLineCol(line,col); with RichViewEdit1 do try linescou...

Will try to find the problem but I didn't change anything in my code before migrating to v.12.

But it's common for all Windows controls. If you open Windows Control Panel - Mouse - Wheel Tab you will see: ----------------------------------------- Vertical Scrolling Roll the wheel one notch to scroll: The following number of lines at a time. ----------------------------------------- So what is...

There is a problem with Access Violation when making undo inside table in RVE 12.0.4 Just create a table, enter something and press Alt+Backspace several times. Sometimes access violation fires on pressing Backspace only or changing cell background color. The problem appears here: function TRVEditRV...

But how wheel works for RVE when scrolls it for the fixed amount of lines?

Also line is a line even if it contains different font sizes you should measure line height by the highest symbol/picture and scroll is a just one line. I think.

Try to undo inside table in RVE 12.0.4 - you will get access violation.

Ok, thanks for the sample, will study it.
But how can I know if last image was processed and document is ready?

It scrolls a lot not by line.
How can I scroll by line using WheelDelta from OnMouseWheel?

I need to manually scroll RVE for some amount of lines (OnMouseWheel).
And this doesn't works for TRichView: RVE.ScrollBy works unexpectedly...
