i am having problem while try to open Access 2000 database which is having password through ADO.

   cannot start your application. workgroup information file is missing  or opened exclusively by another user.

Connectin String:
     Con.Open "Provider=Microsoft.Jet.OLEDB.3.51;Password=te;Persist Security Info=True;Data Source=\\Maxnt\d\Test\test.mdb"

   if any knows the solution for this pls send me.  I want to open database through connection string only. I dont want to create DSN.

Make sure your database is not open exclusively > Close any form in Design Mode, see if the problem remain..

You are using the wrong password syntax, it should be:

Con.Open "Provider=Microsoft.Jet.OLEDB.3.51;Jet OLEDB:Database Password=te;Persist Security Info=True;Data Source=\\Maxnt\d\Test\test.mdb"

The Password parameter is for a user name/password combination whereas the database password requires the "Jet OLEDB:Database Password=" parameter in the connection string.

Dont use 3.51 Jet use 4.0

Since 3.51 cannot open the AccessDatabase 2000.

And also your password syntax is wrong as mentioned by TimCattee

use the below code

Con.Open "Provider=Microsoft.Jet.OLEDB.4.0;Jet OLEDB:Database Password=te;Persist Security Info=True;Data

I don't have the answer, but if the ones already posted don't work, maybe someone can help you with this idea:

Your error message specifies the "workgroup information file".  If you have implemented database security, you have created a custom .mdw file (at least that was the extension in Access97).  The .mdw file holds users, groups, passwords, and permissions.  In order to open the database in Access, you have to either use the wrkgpadm program to permanently join the workgroup (until you join another) or start access with a command line parameter indicating which workgroup to temporarily join.  You can only be in one workgroup at a time.

To test if this is the problem, on the machine you're running your program on, use the access wrkgpadm program (in the windows\system directory) to "join" the workgroup for this database.  This sets something in the registry to indicate the workgroup.  If your program now connects, this is your problem.  

I do not know how to pass the workgroup parameter through an ado connection string.
