Search a specific directory on a specific drive

P: n/a
I have been trying to edit the Explorer example by Dev Ashish I found
on www.msvp.org (I think). I have been all over the net so I am not
quite sure where the file came from.
I like the way it works but I can not find a way to tell it to display
a certain directory. I want it to display a folder on our share drive.
I know the path for the directory. I want users to be able to open any
files below the parent directory I tell it to start in.
So, I don't want to to search for all the drives on the user's
computer.
I am very new to programming in VB and need detailed instructions if
possible.
There are 4 modules and a form. I know it is best to post the code but
since it is so long I tought I would ask which module I should post
instead of posting them all.
Oh, I am using MS Access 2002. The files I want to access are on the
shared drive with the database (different directory).
Let me know if more information is required. I will look for the web
site where I downloaded the files and post it here. Until then, any
help would be appreciated.
Thanks in advance.

I use AK2 and have a table "Paths" that holds paths to various things that
might be of interest in that database such as where the backend is stores,
where the photos are stored, where the help file is etc.

The routine for looking for a file or directory starts from the location
found in paths and opens the directory open dialogue box.
Nicked from various sources

Can probably send something if you are interested

Thanks. I would like to try that. It sounds like a good solution to my
problem since I think there will be more instances when I will need to
have users open a file on the shared drive. Please send a URL to the
download site. Is it free? Are there any known problems in setting it
up?

OK. I did not understand that AK2 was Access 2002.

I am very interested in anything you can send. I will try to create a
table with the paths now.

OK. I found another script and got the module to start in the
directory I want BUT it does not open the file once I double click on
the name. It just closes the browsing window. I have pasted the code I
am using below.
Where and how do I set it to open the file I select using its default
application?

Thanks in advance.
