Retrieving rows from a MS Access Database View using Vb.Net

I've managed to get the following code...

            con.ConnectionString = My.Settings.dbConnection
        Dim sqlCmd As System.Data.OleDb.OleDbCommand = New System.Data.OleDb.OleDbCommand()
        con.Open()
        sqlCmd.Connection = con

        Dim schemaTable As DataTable
        schemaTable = con.GetOleDbSchemaTable(System.Data.OleDb.OleDbSchemaGuid.Views, Nothing)

To retrieve a list of Views in my Access database, but now I want to retrieve the results based on a selected View.

Is there a correct method in doing this, or do I take the SQL Statement from the DataTable returned for each row?

Suppose you have Query1 (View) in your Access database (Database1.accdb file). The following code will output each row of the query to the console (for demo purposes):

    Dim con As OleDbConnection = New OleDbConnection()

    con.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Database1.accdb;Persist Security Info=False;"
    Dim sqlCmd As OleDbCommand = New System.Data.OleDb.OleDbCommand()

    sqlCmd.CommandType = CommandType.StoredProcedure
    sqlCmd.CommandText = "Query1"
    sqlCmd.Connection = con

    con.Open()

    Dim reader As OleDbDataReader

    reader = sqlCmd.ExecuteReader()

    If reader.HasRows Then
        While reader.Read()
            Console.WriteLine(reader("Column1")) 'output specific column
        End While
    End If

    Console.ReadLine()

Hope this helps
