Anyone knows if it is possible to make a database connection over TCP/IP to
an MS ACCESS database? If yes please give me an example or any documentation
please.

Best regards,

Nuno

MS Access is a desktop database management system. Access and the Jet
drivers do not support to use a port in the network. If you want to access
the database over the intranet or internet, you should use an other database
management system like MS SQL Server or MySQL.

Umm, I would say "No". Access is a file based database and does not have
any service or program running at the site of the database, whereas other
programs, such as SQL Server and Oracle do.

You *could* approach it in two ways:
1. Create a program that runs on the Access machine, listens for TCP
connections, accepts queries and returns recordsets or status flags in raw
binary or XML code. This, I suppose can also be accomplished using SOAP or
Remoting.
or
2. Use IIS to simplify it and just create 'post' pages that accept SQL
commands and return recordset in XML, then parse them in your own program.

Nuno,

Those who tell you that you can not do this have not fully explored the
alternatives, or they simply have not used Jet 4.0 this way. I have three
applications that use Access databases this way. One of them uses wireless
PDA devices to access Jet files. For small applications this is fine. You
have to make sure, though that you are not passing a great deal of data over
the network or it will be slow.
Using an IP address instead of a DNS name such as "\\MyNetComputer\MyData\"
is actually faster because the DNS name does not need to be resolved. There
are several things you can do.
1. If you have access to the data at the IP address you can use it in your
connection object just as if you had used the DNS name.
2. You can create a VPN tunnel to the data using the IP address if your
operating systems on both ends support them.
3. You can create a Network Place on your system using the IP address.

Assuming you are not trying to pass large datasets over the Internet it
doesn't matter where you are.

I think the wrong word is access the database, Everybode can access a
textfile over the Internet or a network.
I think you did you mean something as direct access (connection) to the
database?
Just one wrong word in English.
But people love to correct you, be proud.

Herfried,

Sorry you are incorrect. I do this everyday. If the client has large
datasets I put him on SQL 2000. IP addresses work to access ANYTHING just
as if I use a DNS name.

Regards

Nuno,

One thing to watch out for is the security system in Access. When I use
Access over the Internet I require the user to drop all Access security and
use Windows security to establish who can read/write the file. Access
security can get in the way when establishing connections.

Yes. That's what I wanted to write.

Thanks for the information. I am not really familiar with databases
(especially Access databases), but I read what I wrote somewhere some time
ago...

I don't think you are *directly* accessing the database over TCP/IP. On
which port should I or the Jet Engine connect? What's the protocol? What's
listening on the server for the client's requests?
