        Dim TABLE As New DataTable
        Dim i As Integer

        With sqlcmd
            .CommandText = sqlQuery
            .Connection = conn
        End With

        With sqlAdapter
            .SelectCommand = sqlcmd
        End With

        For i = 0 To TABLE.Rows.Count - 1
            With lvresult
                With .Items(.Items.Count - 1).SubItems

                End With
            End With
    End Sub

    '    Private Sub btn_search_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn_search.Click

    'Select Case Me.cmb_search.Text

    'Case "by Name"
    'Me.txb_search.Enabled = True
    'Dim comm_sender As New MySqlCommand("SELECT * FROM Name WHERE `Sender` LIKE '%" & Me.txb_search.Text & "%'", conn)
    'Dim rdr As MySqlDataReader = comm_sender.ExecuteReader

    'contact = rdr.Item("Phone")
    'guest = rdr.Item("NoGuest")
    'room = rdr.Item("NoRoom")
    'book = rdr.Item("BookingType")
    'payment = rdr.Item("Payment")
    'adate = rdr.Item("ADate")
    'ddate = rdr.Item("DDate")
    'messsage = rdr.Item("Message")

    'Me.lvresult.rows.Add(number, roomtype, pangalan, lugar, email, contact, guest, room, book, payment, adate, ddate, messsage)

    'count = Me.lvresult.Rows.Count
    '         If count = 0 Then
    '              Me.Label1.Text = "No document/s found."
    '           Else
    '                Me.Label1.Text = count - 1 & " " & "document/s found."
    '             End If
    '          End While

    '   End Select
    'End Sub
End Class

hope somebody can help me

You should have a different SQL clause depending on your search box. Procedure LoadPeople should start like this

Dim sqlQuery As String

Select Case ComboBox1.SelectedValue.ToString()
    Case "Name"
        sqlQuery = "SELECT * FROM reservation ORDER BY Name"
    Case "Room type"
        sqlQuery = "SELECT * FROM reservation GROUP BY RoomType"
End Select

Since you execute this code from the form's load event, you have to fill search combo in there and set a proper combobox index in order to load "default view" (which could be empty too).
