Hi Suren,

wow, great progress! For the editing, one easy way out would be to
use the SystemShellExecute service, which will pick an app
registered for the file type at hand. You can e.g. find a usage
example in sfx2/source/dialog/about.cxx:298 

A smallish nit regarding the move of lcl_GetPreferedExtension to a
header - better rename it GetPreferedExtension, remove the static,
have the declaration in the header - but keep the code inside a cxx.

Have a look at e.g. sw/source/ui/shells/grfsh.cxx:238

A rather blunt method is to call SwWrtShell::InvalidateWindows(),
that basically forces a repaint of the given rectangular area. Would
have to dig a bit for the Writer method du jour for this case, maybe
the code from grfsh.cxx above has the right call already, e.g.
UpdateFlyFrm() or somesuch.

Keep going, this starts to look *really* nice! :)

Cheers,
