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
ThisAddIn)
        Dim spTask = New Task(Sub()
Globals.ThisAddIn.readToSP())   
    End Sub
End Class

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

How to disable click event in slideshow until animation is finished and then bind it again?
You can easilly make this with a flag. var animationRunning = false; function showSlideNext(idNext) { if (!animationRunning) { animationRunning = true; //do what ever //animation done animationRunning = false; } } This wait the click or next or prev will have no effect. I'm sure you get the idea.

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. This is a mistake - an unfortunately common one brought on by the mistaken use of inheritance in many of Twisted's protocol implementations as the mechanism for building up more and more sophisticated behaviors. When you use twisted.protocols.ba

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
