[RESOLVED] How to stop my application in a loop.

Hello everyone... I have something to ask again.. I develop a program that will send bulk messages but the problem is that when I load at least 1000 emails then I want to stop the application I cannot stop it. Is there any way to stop this application without closing the form? So that i can save the file on my listview? Here is my code upon send bulk emails.

Code:

---


Private Sub frmStatus_Shown(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Shown
        Dim i As Integer
        Dim holder As String
        'Dim itemstring As String
        Dim LVITem As New ListViewItem
     

      Try
                For i = 0 To ListView1.Items.Count - 1
                    holder = ListView1.Items(i).SubItems(1).Text
                    sendHTMLmail()
                    ListView1.Items(i).SubItems(2).Text = carrier
                    lblCount.Text = i + 1
                    lblLvwCount.Text = ListView1.Items.Count
                    SmoothProgressBar2.Value = (i + 1) * 100 / ListView1.Items.Count
                    Label1.Text = ((i + 1) * 100 / ListView1.Items.Count).ToString("N", nfi) + "%"

                Next

                btnLog.Visible = True
                btnStop.Enabled = True

       

        Catch ex As Exception
            MsgBox(ex.Message)
        End Try

    End Sub

One problem I encountered also is that once the mail started to send and the user will click my listview my application will stop sending and I cannot stop the application anymore so if this happen I end up the application by using the stop in a task manager. Anyone can help me to this? Thanks in advance and have a nice day.

Hmm... you may find people reticent to help you with a program for automatically sending out thousands of e-mails .

I assume that you have a copy and paste error in your frmStatus.Shown event as you have an "Else If" statement without an "If" preceding it.

put a counter in your codes and increment it every time you send an email, then when counter >1000 you will stop sending, or do you want to stop by hitting a button?

:) I edited my code now paul. Is it the right place paul to put my code in my frmStatus.shown upon sending? Once I started the mail then it won't stop.:(

I want to stop by hitting the button.... How can I do that?

Have the stop button set i equal to whatever is necessary to stop the for loop?

Use a BackgroundWorker. Follow the CodeBank link in my signature and you'll find my submission on the subject, which demonstrates how to update the UI and also how to cancel the background operation.
