Scan Images And Combine To A Single Multipage Tif File?

I had a related question running on this in a different thread,but I was told to start a new thread since the original had gotten off the original topic. I am trying to scan multiple pages from an Automatic Document Feeder Scanner and combine them to a singlemulti-page tif file. I am using two different third party libraries to do this.The first library I am using is to scan the documents. It saves the files to the local hard drive as single page tif files. This library returns the file-names as they were saved on the hard drive. This part seems to be working as advertised. The sourcefor this including a video on how to use it is at:

Dim FileNames As Collection
Dim FileArray As New List(Of String)
Dim Mergename as String
