Drag and Drop File Upload for Microsoft Dynamics NAV 2013 R2

Yesterday evening I spoke at Dutch Dynamics Community event, on invitation by my dear friend Luc van Vugt, and the topic was control add-ins for NAV 2013 R2. Of course, this automatically meant that the audience should see more JavaScript code than C# or C/AL, and that it should be something both fancy and useful. So how about this: you drag and drop a file onto an NAV page, and the file is automatically uploaded and stored in a BLOB field in the NAV database? And yes, it does the same no matter if you call it from the Windows or the Web client. And yes of course, no external components or dependencies needed. As I promised, I would make all the source components available for download after the sessions, and if you just want to take the components, here they are, ready to download, install and abuse:https://vjeko.com/wp-content/uploads/2014/03/DragDrop.zip If you want to know how this thing works and why, read on. Otherwise, just download the thingy, install it (the instructions are included with the file) and abuse it to your fancy.

DotNet Quick Tip: Accessing members with invalid names

A friend asked my by e-mail today about a problem he encountered with DotNet interop: how to access a property of an object, if the property name matches a reserved word in NAV. A simplest example is from the Microsoft.Dynamics.Nav.SMTP.SmtpMessage class that comes bundled with NAV 2013.

Consider this piece of code:

Mail := Mail.SmtpMessage;
Mail.To := 'john.doe@noname.no';

If you try to compile this, it will fail. It’s simple: the To property name is invalid in the C/AL context, because it is a reserved word.

So, how do you fix it?

.NET Tips & Tricks: Mediator Pattern (on steroids)

When I was writing my last post I had a distinct feeling that I was trampling over some boundaries of good NAV design. After all, you should not do stuff like that, NAV isn’t meant to do things like that, or at least that was how I felt.

And then two things happened.

First, I asked myself: what the heck, why not? What exactly is NAV meant to do, and why not things like that? If folks at Vedbæk didn’t provide an out-of-the-box solution for the problem, why should the problem stay unsolved?

Second, my dear friend and a fellow MVP, Hrvoje of Hudo’s Vibe, identified the thing as the mediator pattern. So, the thing I’ve done to NAV, civilized world has been doing to their programming environments for a long time.

And then I decided to take it all to a different level altogether, and expand the simple class which didn’t do much but raise events on itself when its method was called, into a full-scale framework. And here it is, the mediator pattern incarnated into a brand new Dispatcher class, adapted to NAV, and with features that make it truly flexible. I do not dare starting to think what are all the situations where you could put this thing to use in NAV.
