Interop

With .NET Interoperability around, it’s very likely you’ll be synchronously calling external web services from C/AL, to exchange data. I won’t go into discussing whether or not this kind of architecture is good (my own position is that it isn’t), you may end up having situations where your C/AL code simply makes a synchronous call to external systems, such as web services.

Web services in NAV have an interesting feature: they are stateless. For a system which is pretty stateful otherwise, this feature can be outright annoying. You must get used to it, and then make sure you never ever write code as if there was any state preserved on the other end.

.NET Framework is full of programming conceptual gems, that are now at the fingertips of us poor C/AL folks. One of those is generics . However, the C/AL support for generics at the first glance seems rather limited, and the help file says that you can’t specify data types, and that all generics will be instantiated with System.Object as their type.

Passing strongly-typed data to NAV Web services can be trickier than it seems. If you are lucky, you can make your method accept strongly-typed parameters, and you are good to go. However, if you just can’t avoid sending text data, your text must be encoded in EN-US format, otherwise it will cause problems (see this ).

If there wasn’t one already, someone should have invented Belgium. There are two things in this world that I love, and probably shouldn’t (and an oversized red speaker’s shirt I got from Luc today did a darned god job at concealing the unlucky consequences of overly indulging in both of them): beer and chocolate.

If you are a follower of Mibuso.com you may already know that they are organizing NAV TechDays in Antwerp, Belgium, on September 29 and 30, a conference dedicated to all NAV developers, solution architects and technical folks in general.

I’m growing increasingly impatient as the progress bar on my File Transfer Manager is approaching 100%. Behind the cryptical download title—Dynamics.NAV60R2.HR.1097366.DVD.zip—hides the much awaited Microsoft Dynamics 2009 R2 HR (Croatian) release of Microsoft Dynamics NAV.
