The last of the NAV TechDays 2018 demo series comes with a little story.
And that was it! An amazingly cool demo that shows how you can do really cool stuff that falls beyond the visual realm.
Okay, I’ll calm down a bit. Keyboard shortcuts? Seriously? Well, unfortunately, yes. In NAV/BC web client (universal client included) there are almost no keyboard shortcuts. Microsoft is working on some improvements here, but the important thing, allowing developers to bind specific keyboard shortcuts to specific actions, is still conspicuously missing from NAV/BC.
So, I did this demo.

One of the more effective, and probably completely unexpected, demos at Waldo’s and mine NAV TechDays 2018
session was the user profile picture demo. I say “completely unexpected” is that it shows something that you normally don’t expect from control add-ins. When hearing “control add-in”, most developers (but also most Microsoft people) have in mind a visual control that visualizes some data from NAV/BC and possibly allows you to interact with (C/)AL through that piece of UI. However, there are many other things possible, like having a completely non-visual “controls” that tap into the functionality of the web client and extend its functionality beyond what it was originally designed to do.
One of these is the user profile picture.
If you didn’t attend (or watch) the session, this is what the demo is about: it makes use of the user silhouette icon in the upper-right corner (that actually doesn’t represent anything, just sits there) and allows you to take your selfie and then uses that selfie as your profile picture that’s showing there instead. Pretty neat and cool..
How did I do it?

Eric Sevareid famously said that the chief cause of problems is solutions. The same applies to the HTML trick I blogged about yesterday. As soon as you solve the problem of using HTML directly in your control add-ins, another problem arises: what do you do with actual images your control add-in includes?
This post explains how to solve that problem, and how to make it possible for your control add-in to both use HTML for defining UI and use relative control add-in paths to images.
Let’s dig in.

Where is the problem in the first place, and then what is the solution? Let’s dive in.
In my previous post, I’ve written about the situation when you (or somebody you trust) redeclares the $ variable, thus inadvertently breaking all your jQuery code. I’ve also explained how to remedy for it inside the code you write by applying the Immediately Invoked Function Expression (IIFE) or Self-Executing Anonymous Function pattern.
However, is there anything you can do to prevent anyone from trampling over $ or jQuery variables in the first place?
As I said in my last post, yes, and no.
Let’s take a closer look at it.
