Okay I have the folowing code.
VB Code:
  1. Private Sub Timer1_Elapsed(ByVal sender As System.Object, ByVal e As System.Timers.ElapsedEventArgs) Handles Timer1.Elapsed

  2.         mescounter = mescounter + 1

  3.  
  4.         Me.txtmescount.Text = 60 - mescounter

  5.  
  6.         If mescounter = 60 Then

  7.  
  8.  
  9.             processall() ' process all waiting message and e-mails

  10.             mescounter = 0

  11.  
  12.  
  13.         End If

  14.  
  15.         If doweb Then

  16.  
  17.             If curday <> 1 And curday <> 7 Then

  18.                 If curhour > 7 And curhour < 18 Then

  19.                     webcounter = webcounter + 1

  20.  
  21.                     Me.txtwebcount.Text = 60 - webcounter

  22.                     If webcounter = 60 Then

  23.  
  24.                         processweb() ' exports call data to website

  25.  
  26.                         webcounter = 0

  27.                     End If

  28.                 Else

  29.                     webcounter = webcounter + 1

  30.                     If webcounter = 60 Then

  31.                         webcounter = 0

  32.                     End If

  33.                     Me.txtwebcount.Text = "Paused OOH"

  34.                 End If

  35.             Else

  36.                 webcounter = webcounter + 1

  37.                 If webcounter = 60 Then

  38.                     webcounter = 0

  39.                 End If

  40.                 Me.txtwebcount.Text = "Paused W/E"

  41.             End If

  42.  
  43.  
  44.         End If

  45.  
  46.     End Sub

  47.  
  48.     Private Sub processweb()

  49.         If processingweb = False Then

  50.             processingweb = True

  51.  
  52.             Me.Pbweb.Value = 10

  53.             Me.txtwebcall.Text = CStr(CLng(Me.txtwebcall.Text) + upwebsite.getupcalldata())

  54.             Me.Pbweb.Value = 20

  55.             Me.txtwebcomp.Text = CStr(CLng(Me.txtwebcomp.Text) + upwebsite.getupcompdata())

  56.             Me.Pbweb.Value = 50

  57.             Me.txtwebemp.Text = CStr(CLng(Me.txtwebemp.Text) + upwebsite.getupempdata())

  58.             Me.Pbweb.Value = 70

  59.             Me.txtwebcon.Text = CStr(CLng(Me.txtwebcon.Text) + upwebsite.getupcondata())

  60.  
  61.             Me.Pbweb.Value = 90

  62.             Me.txtremwebemp.Text = CStr(CLng(Me.txtremwebemp.Text) + upwebsite.getwebchanges())

  63.  
  64.             Me.Pbweb.Value = 100

  65.             Me.Pbweb.Value = 0

  66.  
  67.             processingweb = False

  68.         End If

  69.      

  70.  
  71.     End Sub

Now my problem is that the processweb() sub can sometimes freeze for minutes on end if our Internet conection is down or running very slowly, currently when this happens the other sub processall() doesn't get run. I'm assuming the whole application is locking up until the processweb() task completes.
To solve this problem would you use threads? and how easy would it be to convert the above to threading, basically I know nothing about threading or even if this is what I need, so perhaps some general pointers would be useful.
