The client is written in vb.net.
The database is Access 2007 with an adp extension. I am trying to connect from vb.net directly to the access database with a adp file extension.
when the user opens the access database directly, he/she is required to enter a Logon name and password.



My vb.net code connection string looks like this:

      msAccessConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & txtFileIn.Text & ";Persist Security Info=True; Jet OLEDBatabase  User Id=xxxxxx; Password=yyyyy;"

      Dim conec As New OleDbConnection(msAccessConnectionString)
      conec.Open()

Error: Cannot start your application. The workgroup information file is missing or opened exclusively by another user.

The ADP files are project files only, they do not contain tables or any data.

As I open the database I enter the User ID and password.  When I click OK, I hold shift key at the same time.  When I do this I can see tables, queries, forms and reports.

The tables are linked from whatever the data source is for the project.

If this is an ADP, then those tables are hosted on a SQL Server. You can examine the ADP project to determine where that server is located, and then connect directly to that server from your VB.NET application.
