Forms Timer and Thread problem

[Ranthalion]

Hi,

I have an application which contains a form with a Forms.Timer. For some reason, the tick event is not getting called... Somehow this is connected to the fact that I start a new thread...

Here are some code snippets.

 Private Sub tmrSchedule_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tmrSchedule.Tick

        Dim processor As New EDIProcessor


        AddHandler processor.ProcessingComplete, AddressOf EDIProcessor_ProcessingComplete


        If tmrSchedule.Enabled Then tmrSchedule.Stop()
        ediWorker = New Thread(AddressOf processor.Run)
        ediWorker.Start()
        last = 0

        'Call Me.EDIProcessor_ProcessingComplete("")
    End Sub


    Public Sub EDIProcessor_ProcessingComplete(ByVal msg As String)
        'Do we need to somehow remove handlers here?
        lstInfo.Items.Add("Process Complete " & msg)
            Call scroll()
            tmrSchedule.Enabled = True
            tmrSchedule.Start()
            pnlTransaction.Text = ""
    End Sub

I disable the timer in the timer tick and enable it again when the processing is complete. I don't understand it, but the timer never fires after that, even though tmrSchedule.Enabled = true, and the interval is set to 20000, so it should be called again 20 seconds after the thread calls the Processing_Complete Event. Processing_Complete event is fired, and everything executes, but tmrSchedule.Tick is never fired again.

tmrSchedule is a Forms timer and not a threading timer. Also, I commented out the creation and starting of the thread, and the timer worked... I do not reference the timer in any other code in the application...

Any clues on why this would happen?

Thanks,
