This is a Dummies tutorial to implementing Azure Functions in Visual Studio Code. As part of a demo & presentation, I have started to create centrally available, .NET based functions, such as barcode or PDF recognition, in Azure Functions. Our consultants should get an opportunity to use central “Comsol Library / Microservices” to save time and effort instead of implementing those wide-spread functions again and again.
In a recent Business Central 16 OnPrem project, a colleague had the problem of having to detect whether a printer was online or offline. Based on this, he wanted to decide on which device the printout should land. After making sure that we were dealing exclusively with network printers, we decided to check whether a […]
Recently we faced an interesting support case with one of our addon customers migrating to Business Central v17. On the customers site, the REST Api calls of our server-side DotNet component constantly kept running into TLS/SSL errors. Since a non-transparent proxy is used in the customer environment it was obvious where the problem had its […]
In a recent project, I had the requirement to create barcodes in a simple and straightforward way. In this context I came across the Open-Source component ZXing. For this component, which is originally implemented in Java, there is fortunately also a C# port on GitHub available. With its help, you can read and write barcodes […]
In the last days I had the case that I worked in an older Business Central v13 customer database with the latest AL Language Extension. What normally works largely without problems, has cost me nerves at the example of the Enums. You get methods displayed that are only supported in more recent versions. So I […]
This is just an undocumented snipped of my KSORT (php) implementation in C/AL using .NET. Maybe someone of you also has the requirement to implement this sorting algorithm. I had to use it in combination with a HMAC calculation for a REST request call. Yes, this doesn’t cover all functions KSORT offers, but it might […]
Here you find a snippet to print to a socket directly in Business Central OnPrem or Dynamics NAV (as the DotNet could be run in C/AL as well). This could be helpful if you would like to print to e.g., Zebra Printers using ZPL. For testing purposes, I can recommend the ZPL Test App for […]
The other day I had a task where I had to do quite an elaborate calculation to be displayed on a Business Central page. Finally I was able to use the new page background task functionality. The idea behind these page background tasks ist as genius as it is simple. Let’s load intensive data in […]
Recently I’ve listened to a genuinely nice and interesting session at Directions EMEA concerning usage of webhooks in Azure Devops. The idea of Kamil Sacek was to create e.g., a docker container with a certain Business Central version for local development. If the developer is creating a new workitem and adding a new branch to […]
Since my colleagues ask me about this from time to time, I have created a small example for the creation of an XML with the new AL types in Business Central. It contains the creation of the document and some nodes, the appending of attributes and filling with text. This should be enough to master […]
