Getting Images from Microsoft Office Document Imaging (MODI) with vb.net

Hello! It has been a long time since my last blog post and I am happy to be getting back to this. I have missed writing this blog more than you have missed me I guarantee it!

That being said, now that this blog has resumed there will be a few changes. The landscape has changed a bit since my last blog entry. While I will still focus primarily on vb.net code I will also be including what I am working on that is WPF and C# related as well as other .NET related topics. Why? Simply because as my skillset has expanded I wanted to share what I have learned and am learning with you as well. I hope you won’t mind!

Today’s topic revolves around getting images from Microsoft Office Document Imaging (MODI). As you recall I have done a lot of Office automation over the years and I was asked to do this for a friend. As I said, it is good to be back!
