Which RVActions version are you using? (RV)Ruler uses a CompVers.inc with compiler defines. If you use an older version the D2007 compiler (VER185) define might be missing in that inc file.

Have you considered using tabstops?

In the application I'm updating this file is been shown in a RichviewEdit. I have debugged an came to a point where I got this error message:
"Poject ef33.exe raised exception Class EJEG with message 'JPEG error #68'."

This error comes in the RVItem.pas in the Procedure DrawImage at the line ...

Would you be so kind to tell us what it was?

True, most of the time I look them up in the source, usually that will give you a hint to look elsewhere or sometimes a comment why it was deprecated and what the new function is (thinking of FileAge at the moment but that one is documented in the help also).
Are you using any deprecated function ...

So if I use StrNew, that's ok?
No problem and even NewStr is not a direct problem if you can live with some compiler hints (these can be switched as well).
It usually means that it will not be maintained in future versions, but also quite often that there is a (sometimes better) replacement in ...

This is a little stange AFAIK StrNew is not deprecated but NewStr is. But NewStr is not used in RichView.

The following is what I use to determine the colwidths of the current row (see RVRuler.pas in UpdateTableEditor for more).

if RulerType = rtHorizontal then
begin
// Setup columns
RVCellLast := nil;
for C := 0 to RVTable.Rows[Row].Count - 1 do
begin
RVCell := RVTable.Cells[Row, C];
if ...

Please send me compiled exe to richview at gmail dot com
(zipped with password protection, otherwise it will be rejected by gmail)

Just for information:
The last time I checked this, it didn't work. The filenames inside a password protected zipfile are still visible and gmail rejects .exe files ...

PS: In Peter's Demo 'unit uSimpleDemo' taDecimalAlign also doesn't work. taDecimalAlign changes to taLeftAlign.
That demo is using Delphi's (read Windows) standard TRichEdit v1.0 this one does not support it and that's why it is off by default.
Maybe it would have been better to not show this ...

What I sometimes use for testing is PDFCreator http://sourceforge.net/projects/pdfcreator/. Maybe an option when you're unable to get to a printer (or just to save some paper).

The ruler component contains two units. 1st is a general unit called ruler.pas this one contains all the basic functionality like drawing, etc. 2nd is rvruler.pas this is specialized unit which does all the specific handling for a richview component like changing the tabs, indents and margins of a ...

Hello Jürgen,

The last time I checked, TRichView did not support decimal tabs (Sergey, correct me if I'm wrong).
What you can do is use a fixed number of decimals with a font having a fixed pitch and then use taRightAlign.

Identifying the tab is not that difficult, the problem is that as soon as you change the alignment of the tab a part of the ruler becomes empty and a new tab will be added on the second MouseDown. To prevent the extra tab, Ruler.pas needs to be changed.

But first identifying the tab, this can be ...

Jürgen,

WM stands for Window Message.
