Actually, the method I know is similar with you. But I found a simple method with 3rd party component from a blog post.

Maybe method in this post is helpful for you.

I've recently looked at lot of free softwares to convert documents to PDF and I must admit that none of them were meeting my requirements. Some converters were not bad but the licenses were to restrictive. I think you will have to find a good non free converter.

You can take a look a this list of PDF converters: Converters

I'd recommend automating Open Office to do the conversion. It's free, and in my experience far more stable than Microsoft Office when being used for automated conversion tasks.

See my answer on similar question here, which includes a code sample.
