Embedding OpenOffice in Visual Studio 2005

Is it possible to use an embedded OpenOffice in Visual c# or
vbasic ? If so,
is it possible to have access to the whole OpenOffice API ?

I'm asking this before starting coding my software so I
don't make a wrong
choice...

PS : does an application that uses the OpenOffice API or
embeds an Open
Office fall under the GPL or can you do a standard
commercial program with
these functions ?

OpenOffice.org licence is LGPL, not GPL. This difference
really matters.

As the term "embedding" is quite unsharp I'm not
sure if that helps: OOo
supports OLE embedding on Windows and you can embed it into
an OLE
container. If you can access the COM object in this
container via CLI
you can access the whole API with c#, but transferring COM
objects into
the world of managed code sometimes can be a hard job.

Accessing embedded OOo objects via OLE automation bridge in
C++ is
possible but not recommended. Accessing the OOo API in
Visual Basic
through that bridge is comparably easy but I lack the
knowledge about
how to get hands on the object in VB. I assume it's not
complicated also.

IANAL but as long as you don't modify the source code of OOo
the LGPL
allows you to use all OOo components in a closed source
program (I think
that's what you meant when you wrote "commercial"
program; commercial
programs can be under (L)GPL also).

Ciao,

I use it for the OOo lists and only rarely read other mails
sent to it.

Yes, what I meant was embedding an OpenOffice Writer or Calc
process in
another Windows form.

Thanks a lot Matthias & Hubert for the fast answer
