Hi all!
When working with Dynamics AX, you can get the following error when opening a form:
Too many forms are currently open, close some forms and try again.
Restarting the client fixes it… for a while.
In my case the problem was that there were too many User objects in use by the Ax32.exe process. You can check how many are used in the Task Manager on the Processes tab. Click View - Select Columns… and select USER Objects from the list, then click OK. There is also a GDI Objects column that you can enable which shows a counter for a similar property (see: Object Categories).
When this is done, you should see a new column. The maximum number of allowed objects is 10000, so when the combined count reaches this point, you will get this error in AX.
When you see an application with a very high number of USER Objects, there is most likely a leak in that application. In my case ,that application was Ax32.exe. Each time I opened and closed the VendEditInvoice form, the number of USER Objects rose with more or less the number of controls on that form. After closing the form, the count didn’t drop, which it did do for other forms. This allowed me to identify that the problem was with the VendEditInvoice form.
This may have many causes, but in my case the cause was in the close method of the VendEditInvoice form. This method is overwritten but the code that was on there throws an error in some cases. A consequence of this was that super() was not executed, which caused the leak.
Conclusion: make sure you call super() on the close method of a form. When you have code that might throw an error, enclose it with a try/catch.
When activation an integration port, you can receive the following error:
The service ‘YourService’ could not be generated.\n Error: ‘YourDataContract.aMethod’ is not a valid data member
The problem is with declaration of the data member YourDataContract.aMethod. This method declaration could look like this:
As you can see, the type of the return value is Description but the type of the parameter is str. These types should be the same as shown in the following example:
Compile CIL after your made the change and redeploy your integration port, and the error should be solved.
When running setup.exe to install Microsoft Dynamics AX 2012 you can run into the following error:
autorun.hta is not a valid win32 application
As seen in the following screenshot.
In my case, the problem was due to incorrect file associations.
To correct these, go to Control Panel – Programs – Default Programs – Associate a file type or protocol with a program.
Locate the .hta extension and make sure it is associated with the Microsoft (R) HTML Application host application. You can change this by clicking the Change program… button.
The following screenshot shows the correct setup for the .hta extension.
Hi All!
So you need to print some files from Dynamics AX? And it also has to work in batch?
Below are 2 methods that will help you do just that.
This was the first method I used, and it works flawlessly when using text files, such as .txt or .csv files. It also works great on .prn files.
To print such a file, you can simple copy the file to the printer. See example code below.
An easy method, but do not use it on binary file types. Doing this would result in and endless stream of pages with unreadable characters on it. Yes… I’ve tried.
A better way to print files is using the System.Diagnostics namespace. This example uses the “printto” verb to print the files to the server. This verb is visible in the context menu when you right click on a file, it will be listed as the option “Print”. Basically we are using Windows this functionality together with file extension associations to automatically print any file type.
A prerequisite is that an application is available that can open and print the files you want to print. If for example you want to print PDF files in batch using this method, you should install PDF reader software on the AOS server.
You can use the code above to do many other things .The functionality is similar to shellexecute, only neater. If you are interested in modifying the code for other purposes using other verbs, you can figure out what verbs you can use using the job below. You will notice that the verbs that are available depend on the extension the file is using.
It takes a while to figure out how to do these things so hopefully this will save someone the trouble of going through that.
Hi everyone :)
Packt Publishing has recently published 2 new book on Microsoft Dynamics AX 2012 SSRS: Developing SSRS Reports for Dynamics AX and Microsoft Dynamics AX 2012 Reporting Cookbook .
I have yet to read them, but Packt Publishing was kind enough to provide me with copies for review, so expect that in the coming weeks.
At first glance, Developing SSRS reports for Dynamics AX is a great book to get you started developing SSRS reports in AX, while the reporting Cookbook will provide you with must-know receipts you will use all the time when developing. One of the receipts came in handy on the very first day I got the book, so yeah, there is value in these books.
I will do my best to get a review out as soon as possible.
Thanks a lot to Packt Publishing and especially the authors Mukesh Hirwani and Kamalakannan Elangovan for writing and publishing these books.
This guest post is written by my colleague Kristof Meesens. Thank you Kristof for contributing.
Lately I was in a deep debugging mode and used the cross references to find out some stuff.
The cross reference is a great help, but if you want to set some breakpoints it can take a lot of work.
For example you want to set a breakpoint everywhere where a field will be written.
You use the cross reference from the table/field and filter on the reference ‘write’
If you want to set a breakpoint you have to edit each line and set a breakpoint.
I created a class KrMeeSysBreakpoints that will be used to add breakpoints from a container.
The container must contain a Path, a Line number and a Boolean to enable the breakpoint.
This container will be added to another container that the class will use to loop
To use this functionality, you can add a button to the form of the cross references.
You can also call this functionality from de search form
An example screenshot from the cross references screen:

Hi all,
My oh my I have a secret guys, I do not like reading very much :). I want to, but I don’t. The books I bought and didn’t read, I tell you…
But I promised you a review, so I read the book and here it is. I’m exaggerating a bit though, the book is very good, so I had fun reading it.
So below is my review (the same one I posted on Amazon, where I gave it 4 stars). Keep in mind that I got a free copy of the book from Packt Publising, so that might influence my score.
Review
As a Dynamics AX developer, you are mostly involved in the development phase of a project. When I get involved in other phases I tend to get confused about what’s going on, how stuff is decided, organized, planned, etc. If you’re a developer and you want to learn about how projects should be run like I do, than this book is exactly what you’re looking for.
That being said, I don’t think this book is really written for developers. I found it a bit hard to follow at some points, mostly because a lot of new concepts are introduced. I would need a second read-through to get it all. Luckily, this book is definitely worth that.
A lot of project managers and senior profiles would definitely benefit from reading this book. It contains a lot of do’s and don’ts that are so true. You’ll notice while ready this book saying to yourself “exactly!”. If some things are going wrong on your projects, and I bet they are, you’ll certainly be able to use this book to improve your project. Or better still, implement Sure Step completely.
The best thing about this book is that it’s about both Sure Step and Dynamics AX, so it’s all pre-processed for AX projects. You also notice that the authors are really knowledgeable on both subjects.
One thing I didn’t like is that although you are installing Sure Step client in the first chapter, it is not really used again in the rest of the book. It’s hard to know what documents are actually referred to in the book. I expected doing more with the client while reading through the book.
All in all, this is a great book and I would recommend it to everyone on the team.
Hi all,
When installing SSRS on a installation where the database was a backup of a customor’s setup, I got the following error:
An error occurred while adding users ‘CustomerDomain\SomeUser’,'Domain\SomeUser2′ to the SQL Server Reporting Services DynamicsAXBrowser role in the folder DynamicsAX. The error is: The user or group name ‘CustomerDomain\SomeUser’ is not recognized..
The solution was to remove all records in the SysServerSessions table.
I had to restart the AOS too for the wizard to be able to connect to the AOS again, but that could just be a glitch on my machine.
I lost some time because of this error, so thanks a lot to Paul A. Noakes for posting the solution here:

Hi all,
Packt publishing has released another book about Microsoft Dynamics AX 2012: Implementing Microsoft Dynamics AX 2012 with Sure Step 2012.
Packt was kind enough to give me a copy for review, so expect a review in the following weeks. If you’re as excited about the book as I am, you can order a copy from packtpub.com or amazon.com.
Thanks in advance to Keith Dunkinson and Andrew Birch for writing this book and sharing their knowledge.
Hi All,
This week, one of our customers got the following error when printing an SSRS report:
An item with the same key has already been added
Redeploying the report didn’t solve the issue. After restarting the AOS services and then redeploying the report, the issue was solved.
I’ve seen some forum/blog post about this, and I can confirm that this works.
This issue has popped up twice already, the previous time being a few months ago. No code was changed or anything, so I have no explanation for the error. Luckily, it’s easy to solve.
After a lot of hard work, the book Microsoft Dynamics AX 2012 Services is finally available for purchase.
Those who pre-ordered will probably have downloaded the e-book already. Others will have to wait for their paper copy to arrive.
I myself don’t have a copy yet, so I’m watching my mail box just like you :). I have received my copies on the 10 jan 2012, yours should arrive shortly!
If you have questions or remarks about the book, just add a comment below or send me an email.
Happy holidays!
Order from Packt Publishing,
from amazon.com,
or from amazon.co.uk.
I’m very proud to present my first book: Microsoft Dynamics AX 2012 Services, co-authored with Kenny Saelen and published by Packt Publishing.
As the title suggests, the book is about services in Microsoft Dynamics AX 2012. The book covers the service architecture, AIF document services, custom services, system services, consumption of web services, SysOperation and much more. A more elaborate description of the contents can be found on the website of Packt Publishing.
We are still working on finalizing the book but it is already available for preorder. I’m happy there is a discount for preorders, so if you want the book, it’s best to preorder it.
I would like to thank everyone that is involved in the making of this book, especially coauthor Kenny and the reviewers.
As we are still finalizing the book, you all have the opportunity to contribute. If you have ideas or things you would like to see covered, post them below and if possible, we will take that into account.
Preorder from Packt Publishing,

P.S. The cover is not final :-)
Hi all!
Tables contain many properties, one of which is the DeveloperDocumentation field. This field describes the purpose of the table, most of the time in the following format: “The [name of table] table contains [what the table contains]“.
When you don’t specify the developer documentation by creating a label, you will get the following best practice error:
Mandatory property DeveloperDocumentation not specified.
When you do create a label, you will get the following best practice warning:
DeveloperDocumentation label should not be marked to be translated.
Wait what?
The solution is to add {locked} in the description of the label using the label editor.
The developer documentation is aimed at developers and should not be translated, so create the label using the same value as the en-us label in all languages.
– This blog post is mostly a reminder to myself, I tend to forget this :)
