Are you trying to bring up the files? Or actually stor them in access. <BR>If you are not trying to bring them actually into access then just list the file name in access(eg. C:/autocad/myautocadfile.dwg) then use that as a varible in your program that brings it up. As for actually having it in access I can't help you. I always use the address method.
I'm assuming someone needs to have this volviewer.exe installed on their puter for them to see the file. With Software Artisans FileManager you could send the file to the browser in binary stream for display...assuming they visitor has the viewer. softwareartisans.com has code samples of the FileManager object if this seems like what you need.
I can;t supply you with code(I do VBscript) but this is what I would do. set the form window to a varible. this varible is then set by the field in access. <BR>SO you have to some VB. If you have a VB compiler try puting a picture on a form and set the file name to a varible. once you can change it like that your all set. <BR>I could tell you how to do it from a web interface:) hope this helps <BR>
