How to catch exception for File already in use "OleDbException (0x80004005)"

I have a .NET application that gets information from Access DB file, it connects to them using System.Data.OleDb.OleDbConnection, the thing is, those file are sometimes unavailable because of a .ldb file that comes and goes, when they're unavailable IIS throws me the message:

Exception Details: System.Data.OleDb.OleDbException: The Microsoft Jet database engine cannot open the file '\SMXH001ABAP05\Database\LeanSuite.mdb'. It is already opened exclusively by another user, or you need permission to view its data.

Wich makes sense to me, the thing is I want to catch that exception so I can redirect them to a "please wait" site, but I haven't manage to catch that type of exception, and right now I don't really know where my Try Catch should be (assuming that's what I have to use).

Here is the aspx.vb file code where the connection is made.

            Dim fila As DataRow

            'Reading Actual Value
            DS = New System.Data.DataSet()
            MyCommandActual.Fill(DS)
            fila = DS.Tables(0).Rows(0)
            lblActual.Text = fila("Value")
            Dim objetoAndon As New AndonDBClass
            'objetoAndon.insertProduction(fila("Value"), 1)
 MyConnection.Close()
End Sub

It looks like you are trying to only read the data with this connection.

See if opening the connection as read only will help here.

Change:

MyConnection = New System.Data.OleDb.OleDbConnection("provider=Microsoft.Jet.OLEDB.4.0; data source=\\SMXH001ABAP05\Database\LeanSuite.mdb")

To:

MyConnection = New System.Data.OleDb.OleDbConnection("provider=Microsoft.Jet.OLEDB.4.0; data source=\\SMXH001ABAP05\Database\LeanSuite.mdb; Mode=Read")

Also has others have suggest wrapping your requests in a try/catch would be helpful.
