VB.NET's Displaying total number in Checkbox.

This post discussed on how to display the total task when a checkbox control is checked.




This is the code:
----------------

Imports System.Windows.Forms.CheckBox
Imports MySql.Data.MySqlClient
Imports System.IO

Public Class Production_Sequence
Dim totaltask As Integer = 0

Dim Production_Sequence() As Integer = {13, 2, 2, 2, 2, 3, 4, 5, 2, 2, 2, 2, 3, 9, 4, _
2, 1, 4, 13, 10, 5, 4, 4, 1, 3, 3, 3, 1, 1, 5, 1, 3, 4, 4, 1, 2, 1}

Dim checkbox() As CheckBox = New CheckBox() {CheckBoxProductionSequence1, CheckBoxProductionSequence2, CheckBoxProductionSequence2_1, _
CheckBoxProductionSequence3, CheckBoxProductionSequence4, CheckBoxProductionSequence4_1, CheckBoxProductionSequence5, CheckBoxProductionSequence6, _
CheckBoxProductionSequence7, CheckBoxProductionSequence8, CheckBoxProductionSequence9, CheckBoxProductionSequence10, CheckBoxProductionSequence11, _
CheckBoxProductionSequence12, CheckBoxProductionSequence13, CheckBoxProductionSequence14, CheckBoxProductionSequence15, CheckBoxProductionSequence16, _

Public Function TotalProductionTask(ByVal x) As Short
Try
If checkbox(x).Checked = True Then

Else
totaltask = totaltask - Production_Sequence(x)
End If
