Code annotations in AL – Please, don’t!

  • Reading time:10 mins read

One of good practices of writing C/AL Code for Microsoft Dynamics NAV since the dawn of civilization was annotating (commenting) code changes. If you are not sure what I mean by that, this is what I am talking about:

While standards varied about > vs +, or < vs -, or what the annotations should include, there was absolute consensus that annotating changes is an absolute must.

And it was a must. It was such an important rule that everyone followed it without questions asked. In my career, I’ve seen one or two situations of somebody changing or deleting a line of code without leaving any comment, and I’ve seen quite a lot of code, believe you me. It was that important.

It was that important in fact that it was one of the first things developers learned when they signed up for the job, and it was one of the rules they all followed from their first day.

NAV TechDays 2019 Goodies

  • Reading time:2 mins read

NAV TechDays is simply the best NAV / Business Central conference there is. I can miss Directions, I can miss other events, but NAV TechDays – no way. There are few events which can match that energy, that community spirit, that enthusiasm, that top-notch deep-dive content. No, there are not few that can match it; there are none that can.

And then when you consider that they manage to attract ever more people to it, all that while publishing all conference content less than a week after conference is over – it just proves to you that the value of NAV TechDays is not in its content or its sessions. Being a part of NAV TechDays has always been an honor, and a pride, and a privilege.

No matter if you were there last week or not, you’ll want to access the conference materials, so here are the links:

Since this is my blog, I’ll also link directly to my Day 1 session about control add-ins development: https://www.youtube.com/watch?v=_IjppPvkmgE

I’ll post the direct link to Waldo’s and mine Day 2 session about APIs as soon as it is available.

Day 2 content is now also available, so here’s the link to Waldo’s and my session about Business Central custom APIs, {ConnectApps}²: https://www.youtube.com/watch?v=9yg-8tLNjzg

Enjoy the content – and see you again next year in Antwerp!

Better late than never: NAV TechDays 2016 goodies

This year my work got a better of me. For five years in a row I have posted all my demos and materials from NAV TechDays sessions right after them. However, this year, I failed. And I apologize for this.

But, as the saying goes, good things come to those who wait, and here it is – all the materials from my “JavaScript Architecture: Turning Pain into Gain” session are here.

Module Binder Pattern proposal

  • Reading time:17 mins read

Whoa! This has been quite an event, the Directions EMEA 2016 in Prague. There has never been this many people (1.700+) and it was quite a pleasure connecting again with old friends, and meeting new friends. Also, it has been quite a pleasure listening to many good sessions, and an even bigger pleasure delivering four of them.

And this is why I am blogging now – to follow up on my promise during my Polymorphic Event Patterns for C/AL. I promised you that I’d post my pattern proposal online, and here I am doing it.

Let’s get started.

Directions US 2016: Goodbye, Phoenix!

  • Reading time:3 mins read

Directions US. What more to say than: wow! This was an amazing conference, again. A lot of people, a lot of vibe, a lot of NAV. And this year, a lot to look forward to.

Microsoft didn’t disappoint with the news. Dynamics 365 is here with new paradigms, apps are the new big thing, and they really are. There are a lot of improvements in NAV 2017, in the technical stack and in the application alike, and there is a new code editor, something the geeky part of the NAV community has been waiting for a long time. All in all, quite something.

As always at Directions, I was busy. This year I got two sessions, and both of them went well. Thanks to all amazing people who participated and shared their thoughts and encouragement. The good tradition calls for me to post my content here on my blog, so here we go.

If you didn’t have a chance to attend NAV TechDays 2015 in Antwerp last month, don’t worry – you won’t miss much, at least as the conference content goes.

As always, Luc has published all the conference content on both Mibuso and YouTube, so you can download it for offline use or watch it online. Either way, it’s all must-see content.

Download from Mibuso: http://mibuso.com/downloads/category/navtechdays2015

Watch at YouTube:

Of course, the first session you’ll want to watch is mine, about client add-ins, so here’s the direct link:

As I said during the session, I plan to dig deeper into the concepts I explained there, when I find time. And time is so difficult to find, or maybe I am looking at all the wrong places?

If this was a joke, then it would be one of those good-news-bad-news jokes. So which one do you want first? To stay true to all jokes of this kind, I’ll start with good news first.

Good news is, you now have TryFunctions, that return true if no error happens, and false if an error happens inside them.

And the bad news? You’ll never want to use them.

Directions EMEA 2015 Session Content

  • Reading time:2 mins read

For me, Mannheim was always a yet another German city, one that beyond its name I knew nothing else about. When it was announced that Directions EMEA 2015 would be in Mannheim, my first reaction was “say what?” And yet, just as last year in Poznan, I was pleasantly surprised, and realized that every place has something to show, spirit to share, and energy to bring.

There are very few conferences that matter to me. One of them is Directions EMEA, and this year it’s the fourth time that I got a chance to speak and share my ideas and hacks with the community. As promised, and in line with my never-broken tradition, I’m publishing all my content on my blog for you to download.

First of all, thank you all who attended my session today. It was a lot of people in the room, and with the competition from Microsoft talking about a very hot topic in the other, bigger room, I really wouldn’t expect to see all of you there. I hope you found the things you saw useful, and that you’ll take advantage of all the free stuff that I am posting today here on Vjeko.com.

NAV TechDays 2014 Pre-conference goodies

  • Reading time:1 min read

So, NAV TechDays 2014 have started, again, with the pre-conference sessions that were all sold out and packed full.

Today I had an extraordinary pleasure to teach the advanced .NET Interoperability concepts to 15 people that came from all over the world, from Brazil to Australia. It was an interesting workshop, challenging – I must say (thanks to Rafael who made me improvise a solution to a typical DotNet limitation), and I am looking forward to delivering two more sessions about .NET and Control Add-ins tomorrow, and on Friday.

As promised, I am making the materials from the presentation available for the download, in case you want to learn the same stuff the attendees learned today.
