Visual Basic

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

If(IsPostBack)Then Return

Dim emp As DataTable=New DataTable("Employee")

Dim lname As DataColumn=New DataColumn("LastName",GetType(System.String))
Dim fname As DataColumn=New DataColumn("FirstName",GetType(System.String))

Dim id As DataColumn=emp.Columns.Add("ID",GetType(System.Int32))
id.AutoIncrement=True
Dim primarykey As DataColumn()=New DataColumn(){id}
