The first error, as I understand, in call of FRichViewEdit.RVData.Format_.
Just remove last boolean parameters (one or more, I do not remember)

The second error, use FRichViewEdit.RVData.MarkStylesInUse, not FRichViewEdit.MarkStylesInUse.

As for the first group of errors, as I understand, the following lines generate it:
if Assigned(rve.OnCurTextStyleChanged) then
rve.OnCurTextStyleChanged(rve);
if Assigned(rve.OnCurParaStyleChanged) then
rve.OnCurParaStyleChanged(rve);
Change them to:
if Assigned(TRichViewEdit(rve ...

Sorry, my mistake.
This version of ScaleRichView requires the new version of TRichView, v1.9.43.2
Please update your copy of TRichView.

May be paragraphs in your RTF file have negative left indents, overlapping the left margin?

It's strange, only one timer is used for all animations in TRichView.
Is the source code there complete? I cannot see where you insert these gifs

I tried exe file, it works ok for me.
What is wrong?

ScaleRichView trial is updated. Must be ok now.

Update 2007-Jul-28: ScaleRichView v1.2.7

This is mainly a bug-fix release. All known bugs are fixed.
New packages: for C++Builder 6 and 2007.

Not all new features are included in the help files yet, it will be fixed in the next update.

Sorry, I missed "r" - it must be not vespAlt but rvespAlt.

Load INI in another RVStyle, then copy styles:

No, sorry. Because it's rarely needed.

You can use this procedure (assuming that rvoTagsArePChars in rve.Options):
procedure InsertTextTag(rve: TCustomRichViewEdit; const Text, Tag: String);
var SL: TStringList;
i: Integer;
begin
SL := TStringList.Create;
SL.Text := Text;
rve.BeginUpdate;
for ...

...
rv.AddHotPictureTag(...);
rv.SetItemExtraStrProperty(rv.ItemCount-1, vespAlt, 'Image');
...

I think you need older version of RichViewActions for TRichView 1.9.21, but unfortunately I do not have it.
Please tell me what exactly errors the compiler generates while compiling RichViewActions. May be I will be able to suggest how to modify RichViewActions to compile them with TRichView 1.9.21 ...

In the current version, TRichViewEdit must have a parent:

TRichViewEdit *rve = new TRichViewEdit(NULL);
rve->Visible = false;
rve->Parent = Form1;
TRVStyle* style = new TRVStyle(NULL);
rve->Style = style;
rve->Format();
rve->InsertText("test");

Besides, initial values of TRichViewEdit created ...

Not, it was not started yet.
Currently I need to release a next major update, and it must be bug free, so adding new features is currently frozen, until the release.
