I actually do have rvoTagsArePChars set true, and virtually the same code

you provide.

Everything works well for links in my standard TDBRichViewEdit usage.

Where it goes wrong, is where I use LoadRVFFromStream to load a standard

TRichView from a TStringStream, and then use SaveHTMLToStream. The content

is the same content also used in TDBRichViewEdit controls, where the links

work well.

As indicated, multiple URLs in the single document (from TStringStream) always

come through with an id of 0 in URLNeeded, so there's never a chance to get

the correct ItemNo from id anyway.

I'm now wondering if loading from an OleString (instead of a binary storage

may be a problem, except that everything (including tables and graphics)

come out correctly. Even the URLs appear with there blue underlined style

in the resulting HTML document - just no actual URL link capability.

Unfortunately, I use C++Builder, where the debugging capabilites don't show

much useful for Delphi variables, so I can't track down the internals myself

very well.
