Service Orientated Architecture & Dynamics GP–the future is bright

Andrew Haywood of m-hance #DYNBC14

Andrew Hayward keynote the m-hance conference earlier in the year

It being late December I’m reflecting on the year, one of the highlights for me was when I got the pleasure of a long chat, one to one, with Chad Sogge & Daryl Anderson and then a quick chat to Errol Schoenfish. I came away having learnt many things that have really changed my whole opinion of the Dynamics GP product future.

The move to service orientated architecture in GP 2015 version is perfect for developers, as is the tighter integration with .NET from Dexterity. This really does open up the product to do virtually anything we can dream up. In my view, this is a really significant moment in the evolution of GP. Today it can now leverage the investment Microsoft has made with the .NET framework and the full Microsoft product stack, including cloud computing.

I also observe Microsoft handing back third party products to the original developers and simultaneously unzipping the core product for more developers to build awesome things upon it. To me this feels like a message that – hey, we can’t be everything to everyone and also keep it all maintained and yet still drive the product forward, it’s time to let you do that for us.  Microsoft have a growing ISV community around that can build great things for specific market verticals,  thus allowing  Microsoft to maintain the framework, core product, adding new features and performance… boy so many features have been delivered recently! The agile development burndown cadence MS have at the moment is really swelling the bullet points in the sales datasheets and giving us plenty of “new toys” to implement! Smile

I do think there are some amazing years ahead of us in the Dynamics world, presenting many opportunities for the ISV community to grow and build some great products on top of our Fargo friends hard work! I can’t wait to see what the next year brings on.

Convergence 2015–Atlanta USA


I just noticed tonight that there is a competition to win Convergence tickets, one has to sell one’s social media soul to enter though, but I’ve tried anyway. If I won, I’d have to find a sponsor pay for the airfare! – Perhaps someone would sponsor me presenting a session like, “.NET Microframework, GP & The Internet Of Things in a Service Orientated Architecture”, for example!

“Enter to win a FREE Up! Pass to Convergence 2015

Don’t miss your opportunity to win your way to Convergence 2015 in Atlanta! We are giving one lucky winner the ultimate Convergence experience with a FREE Up! Pass (valued at $2,145). We are also giving away five $100 gift cards to some of Atlanta's top restaurants. All you have to do is enter our giveaway on Facebook. But hurry, the giveaway ends December 22, 2014 at 11:59pm ET!”

For those of you who don’t know convergence – it is a massive conference in the USA and is packed full of more sessions than you can shake a stick at, on all kinds of subjects Dynamics related.

Buttons not persisting size in Dynamics GP add-in

Steve Endow, posted yesterday on Buttons mysteriously resize on VS Tools Dynamics GP Forms -- VST template bug?This could have a big impact as I’m now working against GP2013R2 and so I set about investigating the issue. Thanks to Steve for sending me a ZIP of his example, from that I confirmed the same buggy behaviour on my environment, what is more, I also confirmed it on my own projects in my environment.

A big thanks Steve for pointing this issue out, here are my findings.

Reproduce the issue

Start new Dynamics GP Add-in Project


Add a form into the project


Drag two buttons onto the form


Resize the buttons so one is significantly larger than standard and one is much smaller than standard.


Save the form Form

close the form down, then open it again in the designer view….


Yes the buttons have defaulted to “default” size.

I have tested this with Visual Studio 2012 & 2013 as I remembered running Dynamics GP Tools is not technically supported for VS2013.

This is an interesting behaviour!


None of the following testing helped:

  • Using Visual Studio 2012
  • Applications.Dynamics / Microsoft.Dexterity.Bridge / Microsoft.Dexterity.Shell dlls from other copies
  • Downloading and installing latest Visual Studio Tools for GP including GP2013R2
  • Trying class library projects

To track down what was going wrong I jumped into the designer file, thinking that the design time values were not being persisted in the DynamicsGPForm1.Designer.cs


From the above screen shot, the sizes are as expected, one button longer horizontally than the other. Clearly the designer is ok, so why this behaviour? Forms that inherit from the type DexUIForm (i.e. “Microsoft Dynamics GP Forms” from project >> Add New Item), have some extra goodness in the designer “tray area”, as shown below. One of those is the dexButtonProvider. This component grabs the buttons in the form and adds some extra properties to them, it allow the developer to give the users the same experience from the buttons in an add-in, as they would have from the native GP Dexterity buttons.

-so this component is overriding the drawing of the button, there we have a lead to the answer.


The DynamicsGPForm1.resx file holds the form resources. If you are “in the know”, then you will know that these providers are persisting design time state through the form resources file, as seen from a snippet below:

<metadata name="dexButtonProvider.TrayLocation" type="System.Drawing.Point, System.Drawing, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a">
<value>107, 17</value>
<metadata name="dexDefaultColorsProvider.TrayLocation" type="System.Drawing.Point, System.Drawing, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a">
<value>260, 17</value>
<metadata name="dexLabelProvider.TrayLocation" type="System.Drawing.Point, System.Drawing, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a">
<value>450, 17</value>

We would expect to be seeing a XML fragment for each button in here, but it is missing. The expected missing fragment would like this, for button1;

<metadata name="button1.DexDefaultsSet" type="System.Boolean, mscorlib, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089">

If you paste this code in before the final </root> element in the resource file, save and open the form again, amazingly the label size is displayed correctly.
The problem seems to be that at design time, when the button is added to the form, the button provider is not writing the information into the resource file that it needs to bind itself to the button correctly.


It turns out there is a work around that forces the form to emit this meta data into the resource file. Simply flip the “Button Type on DexButtonProvider” property of each button on the form. Do this by after creating the button, set the value other than “Standard” and back again to “Standard”.
Now save the form and check the form resource file. The XML that was missing has been generated for the buttons, and it is confirmed by re-opening the form, the buttons will now retain their designed sizes.




There is an issue with both Steve and My environments, or there is a bug in the button provider when used in GP2013R2 and .NET 4.5. I have a work around for now, but may come back to this out of curiosity, perhaps reflecting into the button provider to find the root cause.
