I want to open up a report in acrobat reader using VB. I dont want to add any more references or components, so I am trying to use the Shell command, but cant get it to work.

The line of code is Shell ("start c:\1.pdf"). I get the error file not found. If I try it in a command prompt it works OK e.g start c:\1.pdf. Is it possible to use the start command in shell??, if so how??
