R – Word opens extra blank document

Here is the best way, for me, to add code inside word:

1. Go to Insert tab, Text section, click Object button (it's on the right)
2. Choose OpenDocument Text which will open a new embedded word document
3. Copy and paste your code from Visual Studio / Eclipse inside this embedded word page
4. Save and close

Advantages

The result looks very nice. Here are the advantages of this method:

• The code keeps its original layout and colors
• The code is separated from the rest of the document, as if it was a picture or a chart
• Spelling errors won't be highlighted in the code (this is cool !)

And it takes only few seconds.

The File -> SaveAs filetype is XML because that is what the file open in Word is. If you want it to say 'Word Document (*.doc) then you will need to create a real Word document on the server and not an XML. Just by putting a .doc extension on the filename doesn't change it's real contents. Word knows the file type that is loaded into it and suggests that as the file type when saving. I don't know of any way to override this behavior.
