I have a script that is 90% complete and working. I'm using the older code for getting LRS statements. It is the one that uses tincan.js. I am trying to pull down and parse the following: Actor, verb, object, timestamp and the id under contextActivities. It is the last one that is giving me fits. Could you please look at my last catch/try statement and tell me where I'm going wrong? Thank you.

You are trying to access a property that will never exist:
statements[i].target.contextActivities
The last portion of that will exist in statements[i].context when it exists, which is not always unless you know the statement ahead of time. Pretty much all of the properties should be checked for null before accessing them, doing so will allow you to remove your try/catch blocks. The property names themselves are very stable and the library explicitly assigns null values to known properties. Additionally the other property will hold an array of Activities (when it is populated) so you should access them by index, so contextActivities.other[0].id etc.
For the target property you should check that it is an instance of a particular class as it can contain multiple types of objects (so can actor but they effectively match). In general for this specific task you may also want to leverage the toString methods where possible, they do very similar work.

I am developing a tracking system for candidates
Attached a search button.
But I want a UI to pop up which will show the duplicates if present.
And when one of the duplicates is clicked, it will fill the required details in the form
I have made this.
But the results are the first row which matches the search text in B4
function Search()
{
var ss = SpreadsheetApp.getActiveSpreadsheet();
var formS = ss.getSheetByName("Form");
var dataS = ss.getSheetByName("Data");
var str = formS.getRange("B4").getValue();
var values = dataS.getDataRange().getValues();
var valuesFound = false;
for (var i = 0; i < values.length; i++)
{
var rowValue = values[i];
if (rowValue[0] == str) {
formS.getRange("B7").setValue(rowValue[0]) ;
formS.getRange("B9").setValue(rowValue[1]) ;
formS.getRange("B11").setValue(rowValue[2]) ;
formS.getRange("B13").setValue(rowValue[3]) ;
formS.getRange("E7").setValue(rowValue[4]) ;
formS.getRange("E9").setValue(rowValue[5]) ;
formS.getRange("E11").setValue(rowValue[6]) ;
formS.getRange("E13").setValue(rowValue[7]) ;
return;
}
}
if(valuesFound==false){
var ui = SpreadsheetApp.getUi();
ui.alert("No record found!");
}
}
Description
You could get all the first name matches and show them in a dialog, numbered so its easier to pick. Once the user picks the name you can fill out the form.
To use a dropdown and pick a name, that would require a custom dialog. Doable but more complex.
This script is executed from a menu item.

Description
So I decided to show how a custom dialog can be used to display a list of names to pick from. First a Ui dialog is displayed to use a filter name. If no name is specified all names will be listed.
Using HTMLService a custom dialog is build using the the pushed variable option for an HTM Template.
Once a name is picked from the list google.script.run is used to return the name to the server and the form can be built from there.

I started my first project with the ESP8266.
It's a Temperature Monitor which shows the data on a webserver.
Since I don't want to refresh the page manually to get the new data, I'm using HTTP requests to display it.
I'm sending 3 different requests, one for the current temperature, one for the highest and one for the lowest.
The problem i'm facing is, that the data won't refresh simultaneously, though I am sending all of those at the same time.
That's the code that's sending the requests:
<script>
function getCurrent() {
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
document.getElementById("current").innerHTML =
this.responseText;
}
};
xhttp.open("GET", "readCurrent", true);
xhttp.send();
}
function getHigh() {
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
document.getElementById("high").innerHTML =
this.responseText;
}
};
xhttp.open("GET", "readHigh", true);
xhttp.send();
}
function getLow() {
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
document.getElementById("low").innerHTML =
this.responseText;
}
};
xhttp.open("GET", "readLow", true);
xhttp.send();
}
setInterval(function() {
getHigh();
getLow();
getCurrent();
}, 2000);
</script>
And that's the code handling them:
float temp;
float hoechst;
float tiefst;
void handleRoot() {
String s = MAIN_page; //Read HTML contents
server.send(200, "text/html", s); //Send web page
}
void handleCurrent() {
float t = temp;
server.send(200, "text/plane", String(t));
}
void handleHigh() {
float high = hoechst;
server.send(200, "text/plane", String(high));
}
void handleLow() {
float low = tiefst;
server.send(200, "text/plane", String(low));
}
void setup() {
[...]
server.on("/", handleRoot);
server.on("/readCurrent", handleCurrent);
server.on("/readHigh", handleHigh);
server.on("/readLow", handleLow);
[...]
}
The Loop is just updating the Temperatures with this function:
void updateTemperatures() {
sensor.requestTemperatures();
yield();
float low = tiefst;
float high = hoechst;
float t = sensor.getTempCByIndex(0);
if(t < low) {
low = t;
} else if(t > high) {
high = t;
}
yield();
temp = t;
tiefst = low;
hoechst = high;
}
And handling the clients (server.handleClient())
So my Question: How can I update the data simultaneously, or is that even possible with the ESP8266?
You update the data simultaneously by returning all three values in one request.
That would be the way to do it with any web server, let alone one running on an extremely limited processor like the ESP8266.
You can return all three values at once with code that looks something like this:
void handleAll() {
String results_json = "{ \"temperature\": " + String(temp) + ",", +
"\"high\": " + String(hoechst) + "," +
"\"low\": " + String(tiefst) + " }";
server.send(200, "application/json", results_json);
}
This composes a JSON object with all three values in it. JSON is "JavaScript Object Notation" and is very easy for Javascript to put together and take apart.
You'd also need to update your ESP8266 web server code to add
server.on("/readAll", handleAll);
With this change you can eliminate the other three /read handlers.
And you'd need to update your Javascript. You'd just need to do one call in Javascript, convert the returned text to a Javascript object and read each of the three values from it to set the elements in the DOM. This is something jQuery can so trivially for you.
And, it's 'text/plain', not 'text/plane'.
You might also check out jQuery - it will greatly simplify your Javascript code.
Simply put: You can't update the data simultaneously because there's only one CPU core. Also, you should design with economy in mind, you wanted to have three transactions to get a few numbers... One of the simplest forms of database is CSV, or "Comma-Separated Values"; essentially: values separated by commas.
Knowing the order your temperatures are going to be in the list (low, current, high), you can simply create a new variable, or concatenate your variables in the statement that outputs the data, that's low "," current "," high and that would return you something like -1.23455,23.53556,37.23432 that you can easily split into three by looking for the commas, and using string operators.
Now you can get your three values from a single transaction from the low-spec device!
Good luck! : )
My script is entering into an infinite loop and I have no idea why. I am running this on validate field and I am preventing a change to the field if another vendor bill exists with the same reference number, forcing the user to change the "Reference Number" to be unique. Here is my code:
function validateField(type, name) {
if (uniqueReferenceNum(type, name) === false) {
return false;
}
return true;
}
function uniqueReferenceNum(type, name) {
if (name !== 'tranid') {
return true;
}
var tranID = nlapiGetFieldValue('tranid');
var vendor = nlapiGetFieldValue('entity');
var vendorName = nlapiGetFieldText('entity');
var filters = new Array();
var columns = new Array();
filters[0] = new nlobjSearchFilter('entity', null, 'is', vendor);
filters[1] = new nlobjSearchFilter('tranid', null, 'is', tranID);
filters[2] = new nlobjSearchFilter('mainline', null, 'is', 'T');
columns[0] = new nlobjSearchColumn('internalid');
results = nlapiSearchRecord('vendorbill', null, filters, columns);
if (!results) {
return true;
}
alert("There is already a vendor bill with reference # " + tranID + " for " + vendorName + ". Please verify and change the reference number before continuing.");
return false;
}
For those still facing this issue, you can set the field in question - in this case, Reference Number - to a 'falsy' value such as an empty string. Only return false after checking that the field contains a 'truthy' value. Then display the alert or dialog to the user. This should break the validation loop.
I am new to CRM and I have created a new AutoNumber plugin (actually modified an existing plugin).
I am having issues getting this plugin to work on the CRM side.
I have created the plugin, and I have created a CREATE step. I am confused with the IMAGE creation, and how I need to go about doing this.
Also, I am using the localContext.Trace and I am not sure where to view this information.
Can anyone help me with understanding the exact steps I need to follow to implement this plugin. I will include my code here in case I am doing something wrong. Again, this was a working plugin and I just modified it. I tried to follow the pattern used by the previous developer.
FYI -- I have purchased the CRM Solution Manager utility to help with the deployment process, but still not having any luck.
Thanks in advance for your time.

This is specifically to response to:
I am using the localContext.Trace and I am not sure where to view this
information
From the MSDN; Debug a Plug-In - Logging and Tracing
During execution and only when that plug-in passes an exception back
to the platform at run-time, tracing information is displayed to the
user. For a synchronous registered plug-in, the tracing information is
displayed in a dialog box of the Microsoft Dynamics CRM web
application. For an asynchronous registered plug-in, the tracing
information is shown in the Details area of the System Job form in the
web application.
Hey i have been able to write an nsIStreamListener listener to listen on responses and get the response text following tutorials at nsitraceablechannel-intercept-http-traffic .But i am unable to modify the response sent to browser.Actually if i return the reponse and sent back to chain it reflects in firebug but not in browser.
What i am guessing is we will have to replace default listener rather than listening in the chain.I cant get any docs anywhere which explains how to do this.
Could anyone give me some insight into this.This is mainly for education purposes.
Thanks in advance
Edit : As of now i have arrived at a little solutions i am able to do this
var old;

originalListener: null,
receivedData: null, //will be an array for incoming data.
//For the listener this is step 1.
onStartRequest: function (request, context) {
this.receivedData = []; //initialize the array
//Pass on the onStartRequest call to the next listener in the chain -- VERY IMPORTANT
//old.onStartRequest(request, context);
},
//This is step 2. This gets called every time additional data is available

This example works for me on Firefox 34 (current nightly): https://github.com/Noitidart/demo-nsITraceableChannel
I downloaded the xpi, edited bootstrap.js to modify the stream:
132 // Copy received data as they come.
133 var data = binaryInputStream.readBytes(count);
134 data = data.replace(/GitHub/g, "TEST");
135 this.receivedData.push(data);
installed the XPI then reloaded the github page. It read "TEST" in the footer.
The version of code you posted doesn't actually pass the results back to the old listener, so that's the first thing that ought to be changed.
It also may have interacted with Firebug or another extension badly. It's a good idea to try reproducing the problem in a clean profile (with only your extension installed).
