You will want to look into this.

  Dim sql As String ="select empno from tbl_empinfo"
  Dim cmd As OleDb.OleDbCommand = New OleDb.OleDbCommand(sql, conn)
  Dim a As OleDbDataAdapter = New OleDbDataAdapter(cmd)
  Dim ds As New DataSet
  conn.Open()
  a.Fill(ds)
  conn.Close()
  For Each data_row In ds.Tables(0).Rows
  ComboBox2.Items.Add(data_row.ToString())
  Next
