Hi, I am just trying to find my way in interop and I just need a pointer as
to what I should be doing.

Reading the documentation tells me I need to use "tlbimp" to create an
interop DLL. However, when I do "add reference" and select the COM tab, I
can something fom the list (in this instance, "Microsoft Word 11 Object
Library"), and I can just use the com object straight away.

Am I using com interop by doing this? Is it running tlbimp automatically for
me?

Also I have heard about Primary Interop Assemblies but I don't see how they
fit into the picture.

As a final question, if there are various different ways of accessing word
from a .net application, which is the preferred one

many thanks

Andy

thanks for the reply, but I'm still confused. I have found this blog entry:

http://blogs.msdn.com/eric_carter/archive/2004/08/18/216838.aspx

which seems to state that when I select "Microsoft Word 11 Object Library"
from the list of com objects, I am actually selecting the PIA I presume I
would normally select a PIA from the ".Net" tab of the references dialog
(since it is already a .net assembly) so maybe there is some extra magic
going on behind the scenes.

If I look in the '.Net' tab there is an item called 'office' but there isn't
one called 'word'

See the last part of this doc. for info on the assemblies shown in the "Add
references" dialog

If you'd like to dive into possible explanations for your other question, I
suggest starting here ;)
