Pause Your Code

Look at post #5 for the updated code. :D

This is nice. This will help a lot on the future..

What exactly is the point of the demonstration? There's no pausing whatsoever - you can put 10 on the label instantly, or you can freeze the application. Yay.

Can you please explain more about the demonstration? What does it do, exactly? Am I not pressing the buttons in the right order?

Minitech, As this post is from Nov 19th, 2010 I have no idea what's wrong with code.
It must of worked because if it did not, I would of never posted the code.
I will upload another explain as soon as my replacement SSD will come back.
I lost VS2010 Pro, and all my other stuff when it failed.

Maybe by next Tuesday or Wednesday I will update the code.
RMA takes forever. :bigyello:

But, when you tried this code:

Code:

---

Imports System.Threading
Public Class Form1
    Private Pause As New ManualResetEvent(True)
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Pause.Reset() ' Pause the code
    End Sub
    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        Pause.Set() 'Remove the lock
    End Sub
    Dim i As Integer
    Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
        Pause.WaitOne()
        Do Until i = 10
            i = i + 1
            Label1.Text = i
        Loop
    End Sub

Does the Label text still count up even after you pressed Button1_Click?

Try pressing 3, 1, 2.
3) Starts the code.
1) Puts a lock on it.
2) Removes the lock.

I have updated the code.
I did provided minimum comments inside the code but it should not be that hard to understand.
Use the diagram below to name the elements correctly.
If you have any questions then ask them.

vb.net Code:

Imports System.Threading
 
Public Class Form1
    Private NewThread As Thread
    Private Pause As New ManualResetEvent(True)
    Dim Desideratum_Integer As Integer = 10000
    
    Dim i As Integer
    Private Sub SubThread()
        Try
            Do Until i = 10000
                Pause.WaitOne()
                i = i + 1
                lblProgress.Text = "Number Count: " & i & " out of: " & Desideratum_Integer
                lblPrecent.Text = i / Desideratum_Integer * 100 & " %"
                ProgressBar1.Value = i
            Loop
            lblProgress.Text = "Number Count: " & i & " out of: " & Desideratum_Integer
            lblPrecent.Text = i / Desideratum_Integer * 100 & " %"
            Count_Up.Text = "Start"
            i = 0
            ProgressBar1.Value = 0
            Curr.Text = "Current Task: Done!"
        Catch
        End Try
    End Sub
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        CheckForIllegalCrossThreadCalls = False
        ProgressBar1.Maximum = 10000
    End Sub
    Private Sub Count_Up_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Count_Up.Click
        NewThread = New Thread(AddressOf SubThread)
        NewThread.IsBackground = True
        NewThread.Start()
        Curr.Text = "Current Task: Calculating."
        If Count_Up.Text = "Pause" Then
            Pause.Reset() ' Pause the code 
            Count_Up.Text = "Resume"
            Curr.Text = "Current Task: Paused."
        ElseIf Count_Up.Text = "Resume" Then
            Pause.Set() 'Remove the lock 
            Count_Up.Text = "Pause"
            Curr.Text = "Current Task: Calculating."
        ElseIf Count_Up.Text = "Start" Then
            Count_Up.Text = "Pause"
        End If
    End Sub
End Class
