Far, far easier solution:
Insert a webbrowser control on your screen, name it something (webControl in my example below), then just point to the pdf you want to display in your form like this...
webControl.object.navigate "c:\test.pdf"
OR
webControl.navigate "c:\test.pdf"
webControl.object.navigate only works for me... for some other people, webControl.navigate worked fine for them. Go figure. The cool thing about the web browser control is that you can display images, word documents, excel spreadsheets, pdfs, html pages, etc .. all in one control without having to change anything."
