How Do I: use Microsoft Flow with data from Microsoft Dynamics NAV 2017

Plataan and Microsoft has published last week my first “How Do I” video of this year.

In this video I will show you, how Microsoft Flow can use data from Microsoft Dynamics NAV 2017. Continue reading  

Change default printer from CAL

A while ago Waldo has posted a way to print any document from CAL. Here he showed us how easy it is to print any document with any extension by simple using .NET.
Recently I used this to print merged PDF’s from CAL, but I ran into an issue.

I want to print this PDF’s on a certain printer.
Some products like Adobe cleams to support this by passing some parameters like:

AcroRd32.exe /t path “printername” “drivername” “portname”

But then you are related to specific software and what with the other extensions.
Do you realy want to create separate statements for every extension.
I don’t think so.

Thereby I search for a better way, and here it is.
Why don’t use .NET again to solve this issue.
Instead of passing the printer as a parameter, I will switch my default printer from CAL.

Microsoft Flow Integration one way only

Last week I was preparing a new How Do I video about the integration of Microsoft Flow with Microsoft Dynamics NAV 2017. As you might know Microsoft Flow is a platform were you can easily integration between other systems like Twitter, Facebook, Mail, … . You can find some more information on

“OnAfterObjectsChanged” Event

I think the following scenario will sounds familiar to every developer.

You develop a nice new feature with a couple of tables, pages and codeunits. These new objects needs to be imported in the production environment.

You make a fob file of all your objects or create deltas, import it in the development environment and compiles the objects. And maybe you need to restore the NST, but this is questioned many times. Some are saying this is mandatory but I doubt it.

Before your solution will work, you need to do some setup in every company by opening the pages and provide the right parameters. A very time consuming (aka monkey task) to do and if your head isn’t clear you can forget something or make mistakes.

Would it be nice if the system itself will know when there are objects imported and auto configure your solution? That the system will raise an “OnAfterObjectsChanged” event the first time you open a client after you imported you objects.

That is what I’ve created and I will share it with you in a moment.

The first part is to determine if there are objects imported to the system. As you properly know these are created and updated in the system table “Object”.
Now I need to know when this table is changed from within NAV itself.

First, I thought to use “OnAfterInsert, OnAfterModify or OnAfterDelete¬†Events” on this table, but these will not be raised from within the development environment when you import objects.

But then I come up with the following idea.

As you might know there is a field called “Timestamp” in every NAV table. This is maintained by SQL on every insert and update.
So, if I make a sum of all the timestamps in the “Object” table and compare it with a previous saved value, I know that something has changed and even that there are records deleted!

To get the sum of the timestamps, I used the following SQL statement and executed from within NAV itself.

Avoid Factbox records on Empty pages

Factboxes are more then ever a powerfull way for presenting related information. Normally you link your Factbox through properties, but now and then you need to do this from code.

This works fine if your page has at least one record, because the filtering is set on the “OnAfterCurrRecord” trigger of the page. So when there is no records, no filter is set on you factbox and then all related records are shown. Continue reading
