Not sure what you are asking. The command is SQL specific - not VB.NET and should work. Given, for example, something like this (which assumes a SQL connection) then where does your problem lie:

Dim conn As New SqlConnection()
conn.ConnectionString = "The connection string"
conn.Open()

Dim text As String = "SELECT ItemCode,ItemName,Unit FROM tb_ItemList WHERE Itemcode NOT IN (SELECT Itemcode FROM SubList)"
Dim adapter As New SqlDataAdapter(text, conn)
Dim table As New DataTable()
adapter.Fill(table)
