Answer 1

After performing the app.Quit(), you must do app = null; From my experiences, this will prevent leftover processes from hanging around. Just be sure to do the app.Quit() and app = null in your exception handler as well.

Answer 2

I am thinking close just handles the document open inside word. Remember you can have more than 1 word document open with 1 application. You may want to try either a dispose method, or look at the word objects quit/exit methods (can't remember its been a while).

Answer 3

If you want to end the process you need to call Quit on the Application object - see http://msdn.microsoft.com/en-us/library/microsoft.office.interop.word.applicationclass.quit%28v=office.14%29.aspx

Answer 4

Are you calling Application.Quit , additionally since you're doing Interop it may be worthwhile to release the RCW wrapper.

So basically something like:

yourWordAppObject.Quit();
System.Runtime.InteropServices.Marshal.FinalReleaseComObject(yourWordAppObject);

Note some folks use: ReleaseComObject but there are some potential pitfalls

Answer 5

You must quit the application instance using app.quit(). Document.close() will just close the document. I also suggest setting app.visible = true when you're done processing so your user can close it themselves if all else fails.
