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

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.
