About HTML import:

The components can load HTML files using RvHtmlImporter component.

You can test how it work in the demo from

http://www.trichview.com/resources/actions/

(menu Insert | File).

It has some limitations, for example it does not understand CSS.

There are no methods for loading MHT files. You need to disasseble them on

html and images before loading (I think you can use Indy methods working

with MIME for this).

Important note: HTML import is HTML import. HTML features that cannot be

understanded by the component are lost on import.

Frames are not supported.

There are no built-in support for videos. You can insert any Delphi

component in TRichView, but RvHtmlImporter does not support loading video.

Yes, there are dataaware versions of components

If you'll be able to load documents, you'll be able to print them.

Besides, TRichView objects can be inserted in ReportBuilder reports.

> 3. Is there anything RV does NOT support that MS RichEdit does?

- Ole objects can be inserted in TRichView only via TOleContainer and cannot

be saved/loaded in RTF like MS RichEdit does

- New version of MS RichEdit has better support for Asian languages

(TRichView supports IME, but not on the level of MS RichEdit)

In any case, I recommend to test beforehand :)

Note: I just uploaded new version (1.9)
