Equivalent VB.Net stored procedures in Excel VBA?

The following are stored procedures used in a VB.Net program I have. Now, if I wanted to transfer it to Excel, what is the equivalent code to be used in VBA?

Dim ds As New DataSet()
Dim da As New OleDbDataAdapter()
Dim conn As New OleDbConnection()

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As system.EventArgs) Handles MyBase.Load

    conn.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=E:\ADODB\sample.accdb;"

    da.SelectCommand = New OleDbCommand("SELECT * FROM tbl_Master")
    da.SelectCommand.Connection = conn

    da.UpdateCommand = New OleDbCommand("UPDATE tbl_Master SET FirstName = @FirstName, LastName = @LastName, Location = @Location WHERE EmployeeID = @EmployeeID")
    da.UpdateCommand.Connection = conn

    With da.UpdateCommand.Parameters
        .Add("@FirstName", OleDbType.VarChar, 40, "FirstName")
        .Add("@LastName", OleDbType.VarChar, 40, "LastName")
        .Add("@Location", OleDbType.VarChar, 40, "Location")
        .Add("@EmployeeID", OleDbType.Integer, 5, "EmployeeID") 
    End With

    da.InsertCommand = New OleDbCommand("INSERT INTO tbl_Master(FirstName, LastName, Location) VALUES(@FirstName,@LastName,@Location)")
    da.InsertCommand.Connection = conn

    With da.InsertCommand.Parameters
        .Add("@FirstName", OleDbType.VarChar, 40, "FirstName")
        .Add("@LastName", OleDbType.VarChar, 40, "LastName")
        .Add("@Location", OleDbType.VarChar, 40, "Location")
    End With

    da.DeleteCommand = New OleDbCommand("DELETE FROM tbl_Master WHERE EmployeeID = @EmployeeID")
    da.DeleteCommand.Connection = conn

    da.DeleteCommand.Parameters.Add("@EmployeeID", OleDbType.Integer, 5, "EmployeeID")

    da.Fill(ds)

End Sub
