My code is below
Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
For i = 0 To RichTextBox1.Lines.Count - 1
Dim MessageThread As New System.Threading.Thread(AddressOf Checkpath)
MessageThread.Start(i)
Next
End Sub
Public Sub Checkpath(ByVal i As Integer)
Dim url As String
Try
url = RichTextBox1.Lines(i).ToString
Dim req As HttpWebRequest = DirectCast(HttpWebRequest.Create(url), HttpWebRequest)
Dim response As HttpWebResponse
Dim resUri As String
response = req.GetResponse
resUri = response.ResponseUri.AbsoluteUri
RichTextBox2.AppendText(resUri & vbNewLine)
Catch ex As Exception
unexpected += 1
MsgBox(ex.ToString)
Label6.Text = "Unexpected: " & unexpected
End Try
End Sub
When ever i do this i get error that
Richtextbox i is array outside of bound
but if i use msgbox(i) before the code,
Public Sub Checkpath(ByVal i As Integer)
MsgBox(i)
Dim url As String
Try
url = RichTextBox1.Lines(i).ToString
Dim req As HttpWebRequest = DirectCast(HttpWebRequest.Create(url), HttpWebRequest)
Dim response As HttpWebResponse
Dim resUri As String
response = req.GetResponse
resUri = response.ResponseUri.AbsoluteUri
RichTextBox2.AppendText(resUri & vbNewLine)
Catch ex As Exception
unexpected += 1
MsgBox(ex.ToString)
Label6.Text = "Unexpected: " & unexpected
End Try
End Sub
works fine or if i do like this
Public Sub Checkpath(ByVal i As Integer)
Dim url As String
Try
MsgBox(i)
url = RichTextBox1.Lines(i).ToString
Dim req As HttpWebRequest = DirectCast(HttpWebRequest.Create(url), HttpWebRequest)
Dim response As HttpWebResponse
Dim resUri As String
response = req.GetResponse
resUri = response.ResponseUri.AbsoluteUri
RichTextBox2.AppendText(resUri & vbNewLine)
Catch ex As Exception
unexpected += 1
MsgBox(ex.ToString)
Label6.Text = "Unexpected: " & unexpected
End Try
End Sub
it works fine but i don't want to display the msgbox
any solution without the msgbox thing?

In this program, the information of the Urls in the "G:\test.txt" are downloaded at the same time, and I want the information to be saved in its own address, in a file with its name(i.e name=t(0)).

I'm programming a tool that'll go through a lot of websites and see if they contain a text that's in a textbox.
Now I wan't to add multi threading so it goes quite a lot faster, most preferably I'd dynamically add threads.
This is my code now but it didn't work because it says index ouf of range. And I doubt it work anyways.
Dim clsThreads As New Generic.List(Of System.Threading.Thread)
Dim numberOfthreads As Integer = 1
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
For Each strLine1 As String In TextBox1.Text.Split({vbCr, vbLf}, StringSplitOptions.RemoveEmptyEntries)
For Each strLine2 As String In TextBox2.Text.Split({vbCr, vbLf}, StringSplitOptions.RemoveEmptyEntries)
clsThreads(numberOfthreads) = New Thread(Sub() Me.request(strLine1, strLine2))
clsThreads(numberOfthreads).Name = "Thread: " + numberOfthreads.ToString
clsThreads(numberOfthreads).IsBackground = True
clsThreads(numberOfthreads).Start()
numberOfthreads = numberOfthreads + 1
If (numberOfthreads.Equals(20)) Then
numberOfthreads = 0
End If
Next
Next
End Sub
So, how do I implement multi threading in a smart way?
This is my request sub:
Public Sub request(ByVal username, ByVal mail)
Dim req As WebRequest = WebRequest.Create("http://localhost/" + username)
req.Method = "GET"
Dim res As WebResponse = req.GetResponse()
Dim dataStream As Stream = res.GetResponseStream()
Dim reader As New StreamReader(dataStream)
Dim responseFromServer As String = reader.ReadToEnd()
If responseFromServer.Contains(mail) Then
TextBox3.Text = TextBox3.Text + vbNewLine + username
End If
End Sub
End Class
Something like this?
Option Strict On
Option Explicit On
Option Infer Off
Public Class Form1
Dim ActiveThreads As New List(Of System.Threading.Thread)
Delegate Sub delRemoveThread(thread As Threading.Thread)
Sub removeThread(thread As Threading.Thread)

End If
End Sub

For i As Integer = 1 To 20
Dim th As New Threading.Thread(New Threading.ParameterizedThreadStart(Sub()
request("username", "mail")
removeThread(Threading.Thread.CurrentThread)
End Sub))
th.Start()
Next
End Sub
Public Sub request(ByVal username As String, ByVal mail As String)
Dim req As Net.WebRequest = Net.WebRequest.Create("http://localhost/" + username)
req.Method = "GET"
Dim res As Net.WebResponse = req.GetResponse()
Dim dataStream As IO.Stream = res.GetResponseStream()
Dim reader As New IO.StreamReader(dataStream)
Dim responseFromServer As String = reader.ReadToEnd()
If responseFromServer.Contains(mail) Then
TextBox3.Text = TextBox3.Text + vbNewLine + username
End If
End Sub
End Class

Edit: I've made the following edit to the code but I'm not entirely sure it's doing what I think it's doing. Basically what I intended is for the ReportProgress to only run once every 2047 bytes read.

Do
If amcworker.CancellationPending = True Then

Return
End If
StopWatch.Start()
If cycle = True Then
amcworker.ReportProgress(CShort(count / Length * 100 + 0.5))
Else
End
End If
read = responseStream.Read(buffer, 0, buffer.Length)
fs.Write(buffer, 0, read)
count += read
Loop Until read = 0
StopWatch.Stop()
responseStream.Close()
fs.Flush()
fs.Close()
End Using
responseStream.Close()
End Using
response.Close()
Catch ex As Exception
MessageBox.Show("An error has occurred during the process:" & vbCrLf & vbCrLf & ex.Message & vbCrLf & vbCrLf & "Please close the application and try again." _

I didn't scrutinize the code carefully, but I don't see why you're using stopwatch, so I took out the references. I'm not sure what starting it multiple times inside the loop and ending it outside would do anyway.
The use of the word END in the second example will comletely end your app! Pretty sure that's what you want there.
Try this modification of your first code. The key is only updating if change is >= 5%:
Using fs As New IO.FileStream(localfileamc, IO.FileMode.Create)
Dim buffer(2047) As Byte
Dim read As Integer = 0
Dim count As Integer
dim LastPct as Short = -5
dim Pct as Short = 0
Do
If amcworker.CancellationPending = True Then
e.Cancel = True
Return
End If
Pct = CShort(count / Length * 100 + 0.5)
if Pct>= (LastPct + 5)
amcworker.ReportProgress(Pct)
LastPCT= Pct
EndIf
read = responseStream.Read(buffer, 0, buffer.Length)
fs.Write(buffer, 0, read)
count += read
Loop Until read = 0
amcworker.ReportProgress(100)
responseStream.Close()
fs.Flush()
fs.Close()
End Using
I am a bit of a noobie with vb.net and I made this application that does a lot of http requests and stream reading. But when it does this it always freezes my application.
So I did a little research and found that I could use background workers to solve this. But I have no idea where to start. So if you could look at my code and tell me where and how I can add background workers to prevent the freezing that would be awesome.

Here's a small sample how to use a worker..

Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
myWorker.RunWorkerAsync()
End Sub
Private Sub myWorker_DoWork(ByVal sender As System.Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles myWorker.DoWork
'do your stuff here...
End Sub
The best way to find bottle neck in your code is to put Timer.Start and Timer.Stop around your methods to find out which methods are taking the longest to excute.
Once you find the offending methods, you can use ThreadPool.QueueUserWorkItem to implement a basic background threading. Threading is by no means easy and it would take some time for you figure it out all the crazy and weird things that happen when you play with threads.
Hope this helps. If you have any more question, do ask.
