The closest thing to stored procedures in access are queries. You can follow the access help and tutorials for information on how to create one.

Once you have it created, you can access it from VB as follows:

    Using conn As New OleDbConnection()
        conn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\myaccess.mdb"
        conn.Open()
        Using cmd As New OleDbCommand()
            cmd.CommandText = "NameOfTheQuery"
            cmd.CommandType = CommandType.StoredProcedure
            ' Note: You can also use CommandType.TableDirect
            cmd.Connection = conn
            cmd.ExecuteNonQuery()
            conn.Close()
        End Using
    End Using

The above assumes that you have the following imports statement at the top of your code:

Imports System.Data.OleDb
