Microsoft Access - how to preview a pdf or word file in forms in access ?

Basically I want to preview a pdf or word file  attached to the record when the  record is selected in MS Acess .
Thanks in advance.

Launch it as a url.  The end user will need Adobe Acrobat Reader to view it.

I should be able to view it in the form itself. 

You'd need to see about purchasing an ActiveX control that will work in Access.  Or, use the web browser control to launch a url on the form.

There is nothing native in Access that will render a PDF document.

Thanks. Could u suggest some activeX controls.
