Thanks for staying with me when i was ready to give up. Here's what the Solution Explorer looks like in my little test project:
Solution 'TestPDFProject'(1 project)
My code looks like this:
MessageBox.Show("Operations Guide.pdf exists: " & System.IO.File.Exists("Operations Guide.pdf"))
Catch nullreference As NullReferenceException
In my first test the reference to the PDF was shown in the top(Solution) section, in the second test it was added to the bottom test. It was not shown in both sections.
The results were the same in both tests, The message box indicate that the file did not exist . The program throws an error before it gets to "Catch".
Thanks again, Rod for trying to help.
