Good afternoon I am trying to insert data from a datagridview in a database of slq server I have it by classes, here the classes if you could help me:

'Insertar quejas 
    Function Insertar_Queja2(ByRef NUM_RECLAMO As String, PRODUCTO As String, ByVal NUM_ORDEN As String,
                    ByVal CANTIDAD As String, ByVal UNID_MEDIDA As String, ByVal FACTURA As String,
                    ByVal PRECIO_UNI As String, ByVal PRECIO_TOTAL As String, ByVal DESCRIPCION As String) As String

        Dim salida As String = "Se genero el Reclamo"

        Dim fila As DataGridViewRow = New DataGridViewRow()
        Try
            For Each fila In frmQuejas.DataGridView1.Rows

            Next
            cmd = New SqlCommand("Sp_InsertarQUeja_Producto", cn)
            cmd.CommandType = CommandType.StoredProcedure
            With cmd.Parameters
                .AddWithValue("@Num_Reclamo", NUM_RECLAMO)
                .AddWithValue("@Producto", PRODUCTO)
                .AddWithValue("@Num_Orden", NUM_ORDEN)


            End With
            cmd.ExecuteNonQuery()
        Catch ex As Exception
            salida = "No se genero debido a: " + ex.ToString
        End Try
        Return salida
