Hi, I can think of 3 possible ways:
1. Create a form based on your table where your .pdf files are kept(Record Source = TableName).
Create a Bound Object Frame (Control Source = OLE Field Name).
In Form View, double click on the Bound Object Frame, will open Acrobat with .pdf file in the current record.
2. Paste this behind a button:
Dim MyAppID
MyAppID = Shell("C:\Program Files\Adobe\Acrobat 4.0\Reader\AcroRd32.exe", 1) 'edit this to location of your Adobe
3. Paste this behind a button:
Dim objAdobe As Object, strFile As String
strFile = "C:\My Documents\Test.pdf" 'this could reference a control
Set objAdobe = GetObject(strFile)
objAdobe.Application.Visible = True
Set objAdobe = Nothing
For option 3 to work I think you will have to have the Full Version of Reader installed
