Part 1–Create an Azure IoT Hub and Device

This is not AX but this was a nice experience. I worked through some labs to interact with Azure IoT Hub.

There is a lot of information out there on the web. So, I will focus on the the IoT Hub only here. On later dates, I may get into the other features of the IoT services in Azure.

Below are the steps to create a device in IoT Hub to get you started. After you have created your device, you can interact with the device in multiple ways.

Go to Azure and Create a new IoT Hub App.


Enter the required information.


Now you can Add Devices manually through the Azure Portal. Otherwise, you can use the SDK to add the device via code.


Now, I will show how to add the device via C#. Create a new Console project.

Add the reference via NuGet.


Search for Microsoft.Azure.Devices and Install it.



Below is the code to copy and paste. Make sure to change the connection string to point it to your IoT Hub.

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using Microsoft.Azure.Devices; using Microsoft.Azure.Devices.Common.Exceptions;

namespace CreateDeviceIdentity { class Program { static RegistryManager registryManager; static string connectionString = ";SharedAccessKeyName=iothubowner;SharedAccessKey=xxxxxxxx"; static void Main(string[] args) { registryManager = RegistryManager.CreateFromConnectionString(connectionString); AddDeviceAsync().Wait(); Console.ReadLine(); } private async static Task AddDeviceAsync() { string deviceId = "myFirstDevice"; Device device; try { device = await registryManager.AddDeviceAsync(new Device(deviceId)); } catch (DeviceAlreadyExistsException) { device = await registryManager.GetDeviceAsync(deviceId); } Console.WriteLine("Generated device key: {0}", device.Authentication.SymmetricKey.PrimaryKey); } } }

Credit to Microsoft for the Labs. Lab doc I found was a little old but most of the steps worked.

AX - How to use Map and MapEnumerator

Similar to Set class, Map class allows you to associate one value (the key) with another value. Both the key and value can be any valid X++ type, including objects. The types of the key and the value are specified in the declaration of the map. The way in which maps are implemented means that access to the values is very fast. Below is a sample code that sets and retrieves values from a map. static void checkItemNameAliasDuplicate(Args _args) { inventTable inventTable; Map map; MapEnumerator mapEnumerator; NameAlias nameAlias; int counter = 0; ; map = new Map(Types::String, Types::Integer); //store into map while select inventTable { nameAlias = inventTable.NameAlias; if (!map.exists(nameAlias)) { map.insert(nameAlias, 1); } else { map.insert(nameAlias, map.lookup(nameAlias) + 1); } } //retrieve fro

AX - How to use Set and SetEnumerator

The Set class is used for the storage and retrieval of data from a collection in which the values of the elements contained are unique and serve as the key values according to which the data is automatically ordered. You can create a set of primitive data types or complex data types such as a Class, Record or Container. Below is sample of a set of records. static void _Set(Args _args) {     CustTable       custTable;     Set             set = new Set(Types::Record);     SetEnumerator   setEnumerator;     ;     while select custTable     {         if (custTable && !         {             set.add(custTable);         }     }     if (!set.empty())     {         setEnumerator = set.getEnumerator();         setEnumerator.reset();         while (setEnumerator.moveNext())         {             custTable = setEnumerator.current();             info(strfmt("Customer: %1",custTable.AccountNum));         }     } } Common mistake when creating a set of recIds

Import document handling (attachment) files #MSDyn365FO

Out of the box you have limited data entities for migrating attachments. If you search what is already in the AOT, you will see a few various examples. I suggest you look at the LedgerJournalAttachmentsEntity as it is the simplest and cleans to copy from. I wont go into detail but I will give a quick run down of what it looks like. Use the DocuRefEntity as your main datasource. It does most of the work for you. Set your table you want to import for as the child datasource Add the Key You will need to add the postLoad method. There is minor code to update the virtual field FileContents. Below is an export I did for the general journal attachments. The import zip structure should be the same way. It will create the usual artifacts such as the excel, manifest and package header xml files. You will see a Resources folder under that. If you drill down to the resources you will see the attachments. This is an export and it used the document GUID for uniqueness. The other thing is the extensi
