TwwRichEdit & changing to TLMDRichText

rbuser

We have recently changed from using Infopower's RichEdit control to
LMD's TLMDRichText.

Previously we used ReportBuilder's TppWWRichEdit to deal with Rich Text
correctly when exported as outlines in the Report Builder tech tips
article : http://tinyurl.com/977uz

Do we need to do anything now that we are using TLMDRichText?

Thanks, Tom.

If TLMDRichText descends from Delphi's TCustomRichEdit then you can probably
use the same technique to register it with RB.

Thanks Nard. TLMDRichText descends from TCustomMemo, we tested the image
issue and it does nto seem to be a problem. I guess it's just a
TCustomRichEdit issue.

Just dotting all the i's for the delphi 10 upgrade.

Cheers, Tom.

Unfortunately testing tested the wrong version :-(

The image shows in the TLMDRichText but not in the report. How can we
register TLMDRichText with ReportBuilder...it descends from TCustomMemo?

Thanks, Tom.

You would need to develop a custom wrapper component for the TLMDRichText.

The TppRichText is a wrapper component for Delphi's TCustomRichEdit.
Therefore it is not going to be compatible. Below is an article with more
details. Note that the publishers of products such as WPTools and TRichView
have developed wrapper components that work with RB.

----------------------------------------------
Article: ReportBuilder's RichText architecture
----------------------------------------------


The RichText in ReportBuilder is a wrapper around Delphi's TRichEdit which
in turn relies on Windows. There are two versions of Windows richedit -
RichEd32.dll is the older one and RichEd20.dll is a newer one (RichEd32 is
being phased out). Delphi by default relies on RichEd32 - the older version.
To use some of the more advanced features of Windows RichEdit, see the topic
on InfoPower RichEdit Support below.

In general Windows RichEdit supports the type of formatting that you can do
using WordPad.

InfoPower RichEdit Support
---------------------------
InfoPower from Woll2Woll Software is a popular database add-on product for
Delphi. InfoPower's TwwRichEdit components support the Windows RichEdit2
format. This format allows the rich text data to contain embedded bitmaps
and OLE objects. For more information please see http:\\www.Woll2Woll.com.

ReportBuilder includes a component that enables the TppRichText and
TppDBRichText controls in ReportBuilder to use the formatting capabilities
of InfoPower's TwwRichEdit when rendering RTF data. The ppWWRichEd.pas unit
located in the ..\RBuilder\InfoPower directory defines a TwwDBRichEdit
descendant and then registers the class with ReportBuilder. This enables the
TppRichText and TppDBRichText controls in ReportBuilder to use the
formatting capabilities of TwwDBRichEidt when rendering data.


WPTools Support
----------------
WPTools is a collection of components used to edit and print formatted text.
With its own RTF engine, WPTools offers numerous features not supported by
the standard Windows RichEd20.dll. This control lets you use tables,
paragraph frames, headers and footers etc. Using the optional ReportBuilder
support units for WPTools 2.x, you can print the enhanced WPTools features
(justified text, tables, graphics...) within your ReportBuilder reports. For
more information please see http:\\www.wptools.de.

TRichView
----------
TRichView is a suite of native Delphi components for displaying, editing,
and printing hypertext documents. Documents can contain tables, pictures,
and images. TRichView is available from www.trichview.com. There is a
wrapper for available for using TRichView inside ReportBuilder, see
http://www.digital-metaphors.com/Subpages/Downloads/CompanionRCL.html or
http://www.trichview.com/resources/

Ok, that makes sense. I have tried to do one like with TwwDbRichEdit but
ppRegisterRichEditClass looks for a TCustomRichEdit descendant and
TLmdRichEdit descends from TCustomMemo.

Right now no images from out rich texts are showing in our reports.

I'm a bit lost what to do. Adding to ppRichTxDrwCmd or whatever is
currently over my head.

Is there anyway Digital Metaphors could work with LMD to get a solution
like you have done for Infopower?

Thanks a lot,

Tom.

We do not have the resources to pursue developing a wrapper component. I
would talk to the publishers of the LMD component about developing one.

TRichView and WPTools have each developed an RB wrapper for their
components.

TppRichText is a wrapper for TCustomRichEdit so any component that descends
from TCustomRichEdit can be registered to work as the rich edit engine for
that component. Examples are Delphi's TRichEdit and Infopower's
TwwRichEdit).

Sorry, but we simply do not have the resources to pursue this right now.
