CypherDrive,
I would avoid Access for anything other than single-user, personal use.
You might also want to look into using one of the open source database
products like MySQL or PostGreSql.

Truly you are right.
Thanks so much.
I have instructed my colleague to ask for a quotation of MS SQL Standard to
solve our problem. There is a 25% Discount on SQL Server up to Sept this
year.
If it is still expensive. We will end up using Visual foxpro 7.0 or MS
Access 2003. In your opinion which among the two is better to use?
So sad to hear that it only functions locally.
Thanks again.
Regards,
Cypher...

Hello Cypher,
The issue of "The file *.mdf is on a network path that is not supported
for
database files" is caused by one of the SQL Express limits:
SQL Server 2005 Express Edition Overview
http://msdn.microsoft.com/en-us/library/ms345154.aspx
<quote>
SQL Server supports using multiple data and log files for a database and
these files can be distributed in multiple file groups. This is not
supported in the AttachDBFileName syntax. *Also the network share, HTTP
paths, or Universal Naming Conventional (UNC) remote databases are not
supported.*
</quote>
Because your mdf is located in a network share and our app accesses the
mdf
through the unc path, the error is thrown for lack of the UNC remote DB
support. Having another license of an SQL Server Express edition run on
that machine will not help either. In other words, if we have to use SQL
Server Expression edition, the DB must be local for it to work. For your
scenario, the possible solutions are:
1. Install SQL Server of Non-Express edition (e.g. Enterprise Edition) and
attach the mdf to the server.
(I can understand that you may not choose this solution according to our
communications in the past.)
2. If the mdf must stay remotely, you may consider building a data access
layer (DAL) on that remote machine (DAL stays with the mdf), and expose
the
interfaces of DAL to our application through the tech like web service. In
this way, our app calls the DAL to do the DB operations.
For more information about DAL, please refer to the articles:
