Connecting Access table to read/ create/delete table using .NET in multi user environment

I am connecting to acces table  to read some info from tbl_Test and will fill the dataset using command object.

I have few concern on this method...

1) The .NET will be used by multiple user so what will be the  best approach i should follow to avoid the common issues like he Microsoft Jet Database Engine cannot open the file ''\\svrPDM\master.mdb". It is opened in exclusive mode by another users. I do have some function which will
create and delete tables in master.mdb  

2) Client user network domain account will not have privileges to access the master.mdb file as it is parked in secured server, what i best way i can code the domain username
and password while perform reading, creating,deleting tables.  If possible ,how do i code in the connection string

Please share your thoughts.


       Dim conn As New OleDb.OleDbConnection
        Dim cmd As New OleDb.OleDbCommand
        Dim oleDBAdapter As New OleDb.OleDbDataAdapter
        Dim dsData As New DataSet
     
       conn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0; Data     Source=\\svrPDM\master.mdb;Mode=read;", "test", "1111")
        cmd.Connection = conn
        cmd.CommandText = "SELECT * FROM tbl_Test"
        oleDBAdapter.SelectCommand = cmd
        oleDBAdapter.Fill(dsData)

Set the connection string to
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\mydatabase.mdb;Jet OLEDB:Database Password=MyDbPassword;Exclusive=0;

You may want to consider using something other than Access as your backend database.

If cost is a concern, SQL Server Express may be worth considering.

You can also force Access to open in non-exclusive mode, but specifying "Exclusive = 0" as part of the JET engine connection string.

Hi,

I  have no choice, have to use access 2000.

How do i connect to the access database using domain user name and password. , default windows login domain act doesnt have the privileges to  access the mdb, in other words i need to code this username/password along with connection string.

Not sure whether writen down my question correctly.

Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\mydatabase.mdb;Jet OLEDB:Database Password=MyDbPassword;Exclusive=0;

Assume MyDbPassword is the password for mdb file.

How do i add domain username/password to access mdb file.

Okay... so you need to impersonate another domain account.

Here's a lionk that explains how using Windows API calls. Not sure if there's a better way in .NET.
