SerialPort.DataReceived Event stops during PowerPoint Slideshow

Okay, so no idea why the program was behaving that way but a work around was indeed to put the "open and monitor" serial port code into a sub in the ThisAddIn class and call it as a new task when appropriate (clicking a button).

Clicking a button on my custom ribbon:

Public Class myribbon    
    Private Sub btn_Click(sender As Object, e As
RibbonControlEventArgs) _
        Handles btn.Click
        ' Define new task spTask (sub located in
        Dim spTask = New Task(Sub()
    End Sub
End Class

Public Class ThisAddIn
    ...' other stuff
    Dim mySP As New SerialPort
    Public Sub readToSP()
        ...' serial port params
            While (mySP.IsOpen)
                Dim analogV As String =
                ...' do something with analogV
            End While
        Catch ex as Exception 'appropriate
        End Try
    End Sub
End Class

How to use dataReceived in Twisted?
I have implemented a server program using Twisted. I am using basic.lineReceiver with the method dataReceived to receive data from multiple clients.

Serial Port DataReceived firing multiple times
You need a state machine to keep track of how far you've progressed in the reception of a message. That can look like this: private int state; private byte[] payload; private int payloadIndex; private void comPort_DataReceived(object sender, SerialDataReceivedEventArgs e) { while (comPort.BytesToRead > 0) { byte b = (byte)comPort.BaseStream.ReadByte(); switch (state) {

Jquery slideshow disable autoplay
It looks like the $counter_slideshow variable could be where your problem lies. If you set a condition to only increment it when you want it to go to the next slide then it should not advance to the next slide. Try setting a flag early on before the you increment the $counter_slideshow variable: //set flag to turn slide show on or off 1 = on 0 = off $slideShowOn = 0; Then you can
