Disabling auto-recovery in word

I'm currently working on an add-in for word 2k3/2k7. I am currently limiting access to documents for users that do not use my add-in. So basically I decrypt the file using my add-in when the doc is opened and encrypt it on document close. The problem I have now is that word has this auto recovery thing 开发者_运维知识库which will save temporary files unencrypted and so if word crashes the users will have access to the doc even if they dont use the add-in.

So my question is, is there a way to programmatically disable auto recovery in word? If not, could anyone suggest another solution for this problem?

I'm not 100% sure it would work, but you can try this:

Sub DisableAutoRecover()
  Options.SaveInterval = 0
End Sub

Note: I wrote a VBA example as I didn't work with C# and Word so far. It shouldn't be difficult to "port" it, though.

 public void getstyle(Word.Document doc) 
        {
            if (doc.Application.Options.SaveInterval==10)
            {
                doc.Application.Options.SaveInterval = 0;
            }

        }
