Dim constring As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Users\bnp\Desktop\Servicios1.mdb"
Dim myconnection As New OleDbConnection(constring)
Dim sql As String = ""
Dim estado As String = "Saved"
myconnection.Open()
If ListView1.CheckedItems.Count > 0 Then
Dim x = ListView1.CheckedItems.ToString
sql = "UPDATE Pedidos SET Ped_est = #estado where x = #x"
Dim acscmd = New OleDb.OleDbCommand(sql, myconnection)
acscmd.Parameters.AddWithValue("#estado", estado)

For II As Integer = 0 To ListView1.SelectedItems.Count - 1

= '" & ListView1.SelectedItems.Item(II).SubItems(0).Text & "'"

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
For x As Integer = 0 To ListView1.Items.Count - 1
' For i = 0 To ListView1.Items.Count - 1
If ListView1.Items(x).Checked = True Then
Dim Stradd12 As String = "INSERT INTO `tbl_student_attendence` ([student_id],[Student_Name],[Activities],[pDate],[pDay],[Ptime]) VALUES (student_id,Student_Name,Activities,pDate,pDay,Ptime )"
'Dim Stradd12 As String = "INSERT INTO `tbl_student_attendence` ([student_id]) VALUES (student_id )"
Dim cm12 As OleDbCommand = New OleDbCommand(Stradd12, DBconnection)
cm12.Parameters.AddWithValue("student_id", CType(ListView1.Items(x).SubItems(0).Text, Integer))
