Personal Experiences with Live Mesh

This post is not going to be about Dynamics AX. It will be about a software product I was thrilled by so much I would like to share it with all of you.

I won't post a detailed description of the product here. You can read that yourself at www.mesh.com. But here is a brief introduction, just to give you a basic idea of what the software can bring into your life.

WHAT IS LIVE MESH?

With Live Mesh, you can synchronize files with all of your PCs (and soon your WM6 phone and Mac as well), so you always have the latest versions handy. Access your files from any device or from the web, easily share them with others, and get notified whenever someone changes a file. Working on one computer, but need a program from another? No problem. Use Live Mesh to connect to your other computer and access its desktop as if you were sitting right in front of it.

Here is a screenshot of the web interface for managing your devices in the mesh:


What I would like to share with you is the personal experiences I had using this software for a month now. In 1 word - fantastic. Live Mesh is still in Beta, but already I can tell you - simplicity is the word. You set it up (takes 5 minutes and is very simple, all you need is a LiveID, which I hope all of you already have). And that's it, you are done. And from then on - it just works. Great!

And here are 2 screenshots of how I use Live Mesh in my everyday life.
Obviously, I have all of my computers meshed, available to me when I need them (they need to be turned on, and have access to internet, of course).



And so far I have 4 folders in the mesh, and I would like to discuss each of them separately:


Personal - I store a backup of my personal data in this folder, which is synced across all my PCs, so that I have it at hand in case I need it. Plus, I have my Personal OneNote workbook in there, with all info I need.
Favorites - Favorites are not synced accross all my PCs, providing the same list on all of them in IE. This is great. This was a feature most of the browsers tried to implement throughout multiple releases. And here it is, as easy as it gets. Any time I bookmark a page, all my other browsers get this page bookmarked as well.
Incoming - this is the folder for file transfer between PCs. Now I don't have to send it to my e-mail every time I need a document scan or something. And, I invite other people as members of this folder, sharing pictures and other documents with them. That easy. And, they get updates every time I add a file, without me having to notify them.
Work - This is my work folder, which I don't sync to my home PC (you can see it is a ghost folder on the screenshot). Any file I work on is automatically synced between my work PCs, so I have an up to date file any time I access it. Extremely efficient.

Well, that's about it. Now, all you have to do is go and try it out yourself.
Have fun!

TableBrowser.NET (a small .NET BC tutorial)

Here is a Visual Studio solution, demonstrating how the Dynamics AX database can be queried through the .NET Business Connector, and how the results of this can be presented to the user in a user-friendly manner.

Here is a screenshot of how it looks:


You can download the solution on axaptapedia.com.

The class to investigate in the solution is the DynamicsAX class. It provides a pretty good interface for reading data out of Dynamics AX.

After opening the solution, make sure to replace the BusinessConnectorNet.dll, pointing it to your AX installation path (if it is not in GAC)

The future of programming languages or Anders Hejlsberg/Steve Ballmer Tech-Pep-Talk

Sunday, September 28, more than 350 IT-professionals from the entire country (Denmark) came to MDCC (Microsoft Development Center Copenhagen) to get a 90-minute TechTalk from Anders Hejlsberg and a 15-minute PepTalk from Steve Ballmer.

Microsoft Dynamics AX 4.0 data model overview

I have great news for you, readers :)
Recently, on an internal Microsoft discussion group, I received a nice document with an overview of the data model for Dynamics AX 4.0.
After permission was received to publish this document to an external audience, I uploaded it to my personal web-site, so that all of you can download it at a convenient time.

The link is below. Enjoy!

SysMultiTableLoookup - dynamic lookups based on multiple tables

Wow! MSDN for Microsoft Dynamics AX is getting better every day. This is terrific news!! I still remember the days, when all the information was extremely hard to find. It had its own charm though :)
Anyway, this topic is really not about MSDN. It is about lookup forms.

First of all, for the record: I (and the Best Practices document as well) recommend creating custom lookup forms in AOT instead of dynamically coding them in the overridden lookup methods on controls/datasource fields.
But, in reality, this is true only for lookup forms with very large complexity. I won't go into a discussion of why that is the way it is here. :)

Now, back to what I was planning to write about:
In order to build a lookup form from code, developers use the SysTableLookup class.
You can go to MSDN (mentioned above) to read a How-to article on creating a run-time lookup form, as well as take a quick look at the SysTableLookup method descriptions.

SysTableLookup class has evolved over the multiple releases, providing more and more flexibility and control to the application developers.
I would like to publish another extension to this class, SysMultiTableLookup, which I hope will prove useful to members of the AX community.

Short list of features:
- Backward compatible, should cover everything that is present in AX 2009 version of SysTableLookup class
- Allows including multiple tables into lookups with different join types
- Completely based on the Query that you build, no extra parameters (except for the control) are needed to initialize the class
- Allows adding aggregated fields to the lookup
- Displays fields based on Boolean Enum as check boxes
- Allows to specify alternative labels when adding fields to the lookup

New download link, as Axaptapedia seemed to mess up the file

You can download the project from axaptapedia.com.


It has (to some extent) been tested on Axapta 3.0 SP3, AX 4.0 and AX 2009.

Also included in the project is a tutorial form, showing 4 examples of dynamic lookups using the new class. After importing the project, make sure to try out the form, and use it for future reference for code examples and other inspiration.
