Hello all,

just wanted to point out that the Ottawa Code Camp will be held on May 4th 2013 at Algonquin College.

My session will be on "Optimizing your 3 tiers apps with current technologies" and we'll take a look at WCF Threading, Tasks Parallel Library and Async-Await pattern.... all that in VS2012... Please note that all this can be done in VS2010 if you apply the Async CTP 3 in your environment.

Here are the details:

Exception handling when using Tasks

Tasks are very impressive once you manage to wrap your head around a few concepts. One subject I’d like to cover in this post is how to deal with exceptions in tasks. There are a few pitfalls one must not fall into when dealing with exception handling in tasks. First you must remember that each task is responsible for its own error checking or error handling. Tasks that do not handle their exceptions will crash your application. How can you avoid that? Continuations to the rescue! There is a concept called Continuations in Tasks and they can easily be implemented to help you deal with exactly that type of problem. All you have to do is “Continue” your task once it's done executing. The continuation code (typically an Action<Task>) is the right place to check if an exception happened during the execution of the original task. There comes the concept of “Observing” a task. A task is deemed “Observed” if you check for it’s Task.Exception property. For example, look at the code below where task1 is continued so that exceptions can be caught. Inside the continuation, you check to see if an exception occurred in task1 like follows:

var task1 = Task.Factory.StartNew(() =>

{

throw new MyCustomException("Task1 faulted.");

})

.ContinueWith( (originalTask) =>

{

if(originalTask.Exception != null)

{

Console.WriteLine("I have observed a " + originalTask.Exception.Tostring());

}

});

Task1 is now Observed and will not crash your application when it throws the exception. Would there be other alternatives to this? Yes, a better way of handling the above would be to pass in the OnlyOnFaulted option to the continuation task (and skip the null check) so the continuation would only happen when the original task is faulted. Another way would be to NOT use the Continuation at all and having previously hooked your code to the TaskScheduler.UnobservedTaskException global event hanler . This event is your last chance to log the exception before your application possibly crashes. Of course, for the application not to crash you'll need to call the SetObserved method on the UnobservedTaskExceptionEventArgs parameter of the event. Typically I recommand that you use Continuations on each tasks AND hook up to this "Global Task Handler" as an additionnal safety net.

Happy coding all !

How I got burned with Automation Ids and virtualized content in XAML controls...

Vincent Grondin — Sun, 06 Jan 2013 02:34:30 GMT

Originally posted on: http://geekswithblogs.net/vincentgrondin/archive/2013/01/05/how-i-got-burned-with-automation-ids-and-virtualized-content.aspx

Not so long ago on our project at work we had to create shared steps in Microsoft Test Manager
for playback later on. The screen we used contained 2 instances of the same custom made combobox
both displaying a list of countries. One was located at the top of the screen and the other one at the bottom.
The combobox already supported Automation IDs and could " auto-magically " generate the right
automation id for each entry to be displayed in the list portion of the combobox according
to the key of each element to display, in this case, the country name. Remember that this portion
of the control is VIRTUALIZED.

Now, the interesting part... We record our test in MTM and in this simple test, we pick a country from
the list of countries at the bottom of the screen. We had done enough recording and coded ui tests
on this control to know it worked great... When came the playback time, we saw our recording do exactly
what it was supposed to do, pick the country we had selected EXCEPT, it did in in the upper combobox instead
of the bottom one! HMMM.... How weird! Both controls had different Automation IDs but had the same automation
ids for the virtualized content because they both displayed the same kind of information being, countries...

OK so the solution was simple, concatenate the controls unique Automation ID with the
unique content for each virtualized row...

The code behind for the control overrides PrepareContainerForItemOverride like so:

//Declare this property inside your control and initialize it inside your constructor
public BindingBase BindingAutomationId { get; set; }

protected override void PrepareContainerForItemOverride(DependencyObject element, Object item)
        {
            base.PrepareContainerForItemOverride(element, item);

            DataGridRow row = element as DataGridRow;

            //Can't put these lines in the constructor because the GetAutomationId call returns NULL consistantly from inside it
            if(string.IsNullOrEmpty(this.BindingAutomationId.StringFormat))
            {
  //The magic is here
                this.BindingAutomationId.StringFormat = AutomationProperties.GetAutomationId(this) + "_{0}";
            }

            row.SetBinding(AutomationProperties.AutomationIdProperty, BindingAutomationId);
        }

So now each virtualized content inside this control has a unique automation id and the playback works perfectly.

Hope this saves you a ton of time trying to figure out why your playback won't pick the control you selected during the recording phase.

Learning the hard way: Uninstalling .NET Framework 4.5RC

Vincent Grondin — Wed, 18 Jul 2012 00:50:38 GMT

Originally posted on: http://geekswithblogs.net/vincentgrondin/archive/2012/07/17/learning-the-hard-way--uninstalling-.net-framework-4.5rc.aspx

Uninstalling the .NET Framework 4.5RC can be a real mess, let me explain…

I had a perfectly functional VM on which I tried to install the 4.5RC version of the .NET framework to test out some of the new features of EF. Since what I wanted to test didn’t work and since I THOUGHT 4.5 and 4 where side by side, I decided to go back to simply 4 and uninstall the 4.5RC from the VM. Big mistake…. Now my Visual Studio would not work at all and kept saying “Unknown Error” when I started it… After further investigation, I saw this post and as you can see in here http://msdn.microsoft.com/en-us/library/5a4x27ek(v=vs.110).aspx

when you uninstall the 4.5 framework it automatically uninstalls the 4.0 framework and ANYTHING related to it! D’oh !!!

I re-installed the 4.0 framework and SP1 and now Visual Studio 2010 started working again. But I wasn’t done fixing issues yet… My application was using EF4 and ODP.NET and now, when I open up the EDMX I would see the following error:

error 175 the specified store provider cannot be found in the configuration or is not valid

I was quite annoyed by this so I decided to simply try to regenerate a new EDMX file from database… but I couldn’t !!! In the drop down box where you choose your provider for the EF connection, Oracle ODP.NET had disappeared !!!! *me throws holy water all around* !!! After much digging around, I found out that the MACHINE.CONFIG file had been modified by the uninstall process and that a very important line had been removed…

If you have this error and you use EF with a particular provider other than SQL Server, check out your machine.config file and see if this section contains the reference to your provider:

<system.data>

</DbProviderFactories>

</system.data>

Mine needed to look like this:

<system.data>

</DbProviderFactories>

</system.data>

Restart your VS and your original EDMX will not complain about error 175 anymore…

But that wasn’t all, I ended up re-installing ODP.NET because my machine.config file was really messed up and missed many entries it previously had… So a word of wisdom (which I didn’t follow, stupid me) is take a snapshot of your VMs before “trying out” 4.5RC and maybe uninstall it later or backup your PC….

Hope this saves you some time…

Coded UI Test Builder Visual Cues Offset

Vincent Grondin — Tue, 17 Apr 2012 00:28:24 GMT

Originally posted on: http://geekswithblogs.net/vincentgrondin/archive/2012/04/16/coded-ui-test-builder-visual-cues-offset.aspx

Wow it's been a long time since I posted anything in here.....

Today I'll be very brief because the subject is quite easy to cover but can be quite puzzling when it happens to you... These days at work I'm exploring Coded UI Test in VS2010, Microsoft Test Manager 2010 and Microsoft Test Runner 2010 which is cool because I've been digging aroung VS2010 testing tools on my own since a year now and also started focusing on VNext's testing tools... So when you automate a test you will most likely end up having to use the Coded UI Test Builder shown here

When inspecting controls on your app with the little "Target" tool, you could be confronted to your controls being highlighted "in the wrong place" on your screen. Kind of like there would be some sort of offset between the control you are pointing to and the visual rectangle cue created by the tool to say "here's the control I think you're pointing to"... Looking at the picture here you can see it's pretty anoying to point at a control, see the tool inspecting the right object but highlighting it lower and to the right of where the control actually is... I have no clue if this only happens in WPF but here's the solution or at least what worked for me... In my case I was using the "Medium - 125%" display setting in the personalization of my Windows 7 laptop... The Coded UI Test Builder only works well when your display is set to 100% (smallest in my case). Change that option to 100% and everything will start being highlighted at the right place in the tool... I do think that this was intentionnal and that the tool was built to work only when using 100%... What a shame but now you know so stop reading and go back to work !

Happy automating :)

The long awaited Dev Teach conference approches FAST and will be held in Ottawa on nov the 2nd to nov the 4th!

Very interesting material both in the main event and in pre-conferences with 2 friends of mine, Laurent Duveau and Mario Cardinal both giving a pre-conference workshop ! For my part, I'll be giving a talk on Mocking and Mocking Frameworks as I really think people need to be more aware of their power and the fact that nowadays, effective, responsive, scalable unit testing inevitably equals mocking frameworks... There is a grand total of 48 sessions planned for the event: 12 sessions by ITProTeach for IT Professionals, 12 sessions by SQLTeach for DBAs and finally 24 sessions by DevTeach for developers.

If you are in the area, you should definitly try to attend the conference....

Bridging The Gap Between Developers And Testers With VS 2010

Vincent Grondin — Mon, 14 Feb 2011 15:31:02 GMT

Originally posted on: http://geekswithblogs.net/vincentgrondin/archive/2011/02/14/bridging-the-gap-between-developers-and-testers-with-vs-2010.aspx

On January 29th Etienne Tremblay and I presented infront of roughly 120 people in Ottawa a 7 hours "sketch" on how VS 2010 and TFS 2010 can help both devs and testers in their respective work. The presentation focused on how a testers' work can positively influence a developers' work and vice versa. The format was quite unusual as I said it's a "sketch" where Etienne and I "ignore" the audience and we do as if we were at work and the audience is sort of "spying" on us. In all I'm quite pleased with the content we presented and the format sure was alot of fun to render and I think the audience liked it too... The good news for you people reading this post is that it got RECORDED and it's now available for download in quick 25 to 35 minutes format on the dev teach web site:

http://www.devteach.com/ALM-TFS2010-Bridgingthegap.aspx

There were 2 cameras, one filming us and one capturing the screen for our demos. We switch from one to another in an intersting flow and Jean-René Roy made sure he kept all our goofs and didn't edit those funny "oups moments" where we screw-up in the scenario... Mostly educative but hilarious at times !!!

I encourage you all to download and watch the 13 episodes... Follow a day at work for a tester and a developper using VS 2010 and TFS 2010 to improve their chemistry !

Thanks to Jean-René Roy for all the work he's put into this event and to Microsoft and Pyxis for sponsoring the event.

Tips on debugging collections

The "Quick Watch" feature of Visual Studio is an awesome tool when debugging your stuff... I use it all the time and quite often I end up exploring hashtables or lists of all sorts... One thing I hate is when I have to explore Collections... Good god did I lose time trying to find the inner member that contains my stuff when exploring collections... Most collections have the inside member that you can search for and find and explore to see the list of things you wanted to look at. Something in the likes of this.

I've known a little trick for a while now and I give it to everyone I end up debugging something with so I figured that probably not many people know about this... Here's the tip... Send the collection into an ArrayList in the QuickWatch window! Yes, you heard me right, just type

new ArrayList(yourcollectionhere)

in my case: new ArrayList(this.Controls)

in the expresion textbox and here's the result when you hit reevaluate!

Pretty neat trick to make your debugging experience less of a pain when dealing with collections...

Happy debugging all !

Developing for 2005 using VS2008!

Vincent Grondin — Sat, 24 Apr 2010 22:43:08 GMT

Originally posted on: http://geekswithblogs.net/vincentgrondin/archive/2010/04/24/developing-for-2005-using-vs2008.aspx

I joined a fairly large project recently and it has a particularity… Once finished, everything has to be sent to the client under VS2005 using VB.Net and can target either framework 2.0 or 3.0… A long time ago, the decision to use VS2008 and to target framework 3.0 was taken but people knew they would need to establish a few rules to ensure that each dev would use VS2008 as if it was VS2005… Why is that so? Well simply because the compiler in VS2005 is different from the compiler inside VS2008… I thought it might be a good idea to note the things that you cannot use in VS2008 if you plan on going back to VS2005. Who knows, this might save someone the headache of going over all their code to fix errors…

- Do not use LinQ keywords (from, in, select, orderby…).

- Do not use LinQ standard operators under the form of extension methods.

- Do not use type inference (in VB.Net you can switch it OFF in each project properties).

o This means you cannot use VB.NET XML Literals.

- Do not use nullable types under the following declarative form: Dim myInt as Integer? But using: Dim myInt as Nullable(Of Integer) is perfectly fine.

- Do not test nullable types with Is Nothing use myInt.HasValue instead.

- Do not use Lambda expressions (there is no Lambda statements in VB9) so you cannot use the keyword “Function”.

- Pay attention not to use relaxed delegates because this one is easy to miss in VS2008

- Do not use Object Initializers

- Do not use the “ternary If operator” … not the IIf method but this one If(condition, truepart, falsepart).

As a side note, I talked about not using LinQ keyword nor the extension methods but, this doesn’t mean not to use LinQ in this scenario. LinQ is perfectly accessible from inside VS2005 if your client allows you to target framework 3.5. All you need to do is reference System.Core, use namespace System.Linq and use class “Enumerable” as a helper class… This is one of the many classes containing various methods that VS2008 sees as extensions. The trick is you can use them too! Simply remember that the first parameter of the method is the object you want to query on and then pass in the other parameters needed…

That’s pretty much all I see but I could have missed a few… If you know other things that are specific to the VS2008 compiler and which do not work under VS2005, feel free to leave a comment and I’ll modify my list accordingly (and notify our team here…) !

Happy coding all!

Using the “Settings.settings” functionalities in VB.NET can be tricky…

Vincent Grondin — Thu, 08 Apr 2010 01:22:49 GMT

Originally posted on: http://geekswithblogs.net/vincentgrondin/archive/2010/04/07/using-the-settings.settings-functionalities-in-vb.net-can-be-tricky.aspx

Sometime you’re searching for something forever and when you find it, you realize it was right under your nose. Maybe you were distracted by other things around… or maybe that thing right under your nose was so well hidden that it deserves a blog post… That happened to me a few days ago while using the “Settings.settings” functionalities in my VB.NET application… I thought it was a cool feature and I decided to use it…

So there I am adding new settings with “USER” scope and StringCollection as the data type, testing my application and everything works perfectly fine... That was before I decided to modify the “Value” of one of my settings… After changing the value of one of my settings, I start my application again and, to my surprise, my new values aren’t showing! Hmmm… That’s odd… My setting was a pretty long list of strings so I was rather angry at myself for not saving my work after I was done… So I open up the Settings.setting in the designer and click the ellipsis symbol to enter my string collection again, but to my great pleasure (and disbelief) my strings are there!!! Alright, you rock VB.NET! You’ve just save me a bunch of typing time and I’m thinking it’s just a simple Visual Studio glitch… I hit “Save” then “Save All” (just in case) and finally I rebuild everything and fire up my app once again. Huh? Where are my darn strings???????? Ok there’s a bug there… I open up the app.config and my new strings are there!!! Alright, let’s recap… My new strings are in the app.config, they show correctly in the Settings.settings designer UI but they aren’t showing at runtime… Hmmmm? Let’s try something else… Let’s start the application but outside Visual Studio this time… I fire up the exe and BAM! My strings where there! I “alt-tab” and hit “F5” and BOOM, no strings! So it’s a bug in the Visual Studio environment… or could it be a FEATURE? I must admit that I’m a little confused over what’s a bug and what’s a feature in Visual Studio… lol! Finally I found out there’s a “cache” for your Visual Studio located here:

C:\Users\<your username>\AppData\Local\Microsoft\<your app name and a very weird temp ID>\<your app version>\user.config

When using the “Settings.settings” with a setting of scope “user”, this file is out of sync with your app.config until you manually decide to update it… The button is right there… under your nose… at the top left corner of your screen in the settings designer… See the big “Synchronize” button there? Yep… Now that’s user friendly isn’t it? Oh, and wait until you see what it does when you click it… It prompts you and basically says: “Would you like your settings to start working inside Visual Studio now that you found out that I exist?” and of course the right answer is yes… or rather “OK”… Unfortunately, you have to do this every time you edit a value… On the other hand, adding and removing settings seem to work flawlessly without having to click this magical button… go figure! Oh and I almost forgot… this great “feature” is only available for VB.NET… A project in C# using Settings.settings will work perfectly EVEN when editing values…

Here’s a screenshot that shows this important button:

Button

Using other data types appears to work perfectly well… Maybe it’s simply related to the StringCollection data type? If you are a VB.NET programmer, you should pay attention to this when you plan on using the settings functionalities and your scope is “user” and your data type is StringCollection…

Happy coding all!

Steps to deploying on Windows Azure

Vincent Grondin — Tue, 16 Mar 2010 02:44:33 GMT

Originally posted on: http://geekswithblogs.net/vincentgrondin/archive/2010/03/15/steps-to-deploying-on-windows-azure.aspx

Alright, these steps might be a little detailed and of few might not be necessary but still it's a pretty accurate road map to deploying on azure...

This procedure assumes that you've created a solution with an Azure project into it.

1) Open your solution

2) Rebuild ALL

3) Right click on your Azure project and click "Publish"

4) It should open a windows explorer window with your package to be uploaded (.cspkg ) and its associated configuration (.cscfg) to be uploaded too. Keep it open, you'll need that path later on...

5) It should also open a browser asking you to login to your passport account, please do so.

6) After this you will be redirected to the Azure Portal where you will see your Azure Project Name below the « Projet Name » section. Click on it.

7) Then you should be redirected to a detailed view of your account on Azure where you will create a new service by clicking the hyperlink on the top right corner.

8) Choose the right service type for you, most likely the "Hosted Service" type

9) Choose a « Label » name and click « next »

10) Choose a name for your service and validate that the name is available in the cloud by clicking the "Check Availability" button

11) At the bottom of this same page, you can choose to create a group for your service, use no group or join an existing group. Creating a group means that all applications that belong to the same group will see no cost to exchanging data between other applications of the same group. Most of the time when you create a single application, creating a group is not necessary. You should choose a region that's close to your own region.

12) On the next window, you should see a "Production" environment and a "Staging" environment. Beware because "Staging" and "Production" are two different environments in the cloud and applications in "Staging" even when not runing do continue to rack in charges... Choose an environment and click "Deploy".

13) In the following window, browse to the path where your cspkg resides and then do the same thing with your cscfg file. Choose a name for your Label, and click "Deploy"...

14) From now on, the clock is ticking and unless you have free Azure hours, your credit card is being billed…

15) Click on the « Run » button to start your application

16) Be patient.... be very patient…

17) Once your application has finished starting, you should see a GREEN circle on the left side of the screen indicating that your application is READY. Click the URL to test your application and remember that if your application is a service, you have to hit the "svc" class behind the link you see there. Something in the likes of http://testvince2.cloudapp.net/service1.svc (this is a fictional link)

18) Hopefully your application will show up or in the case of a service, you will see your service's wsdl meaning that everything is working fine.

Happy cloud computing all!

A few things I learned regarding Azure billing policies

An hour of small computing time: 0,12$ per hour

A Gig of storage in the cloud: 0,15$ per hour

1 Gig of relational database using Azure SQL: 9,99$ per month

A Visual Studio Professional with MSDN Premium account: 2500$ per year

Winning an MSDN Professional account that comes preloaded with 750 free hours of Azure per month: PRICELESS !!!

But was it really free???? Hmmm… Let’s see.....

Here's a few things I learned regarding Azure billing policies when I attended a promotional training at Microsoft last week...

1) An instance deployed in the cloud really means whatever you upload in there... it doesn't matter if it's in STAGING OR PRODUCTION!!!! Your MSDN account comes with 750 free hours of small computing time per month which should be enough hours per month for one instance of one application deployed in the cloud... So we're cool, the application you run in the cloud doesn't cost you a penny.... BUT the one that's in staging is still consuming time!!! So if you don’t want to end up having to pay 42$ at the end of the month on your credit card like this happened to a friend of mine, DELETE them staging applications once you’ve put them in production! This also applies to the instance count you can modify in the configuration file… So stop and think before you decide you want to spawn 50 of those hello world apps .

2) If you have an MSDN account, then you have the promotional 750 hours of Azure credits per month and can use the Azure credits to explore the Cloud! But be aware, this promotion ends in 8 months (maybe more like 7 now) and then you will most likely go back to the standard 250 hours of Azure credits. If you do not delete your applications by then, you’ll get billed for the extra hours, believe me… There is a switch that you can toggle and which will STOP your automatic enrollment after the promotion and prevent you from renewing the Azure Account automatically. Yes the default setting is to automatically renew your account and remember, you entered your credit card information in the registration process so, yes, you WILL be billed… Go disable that ASAP Log into your account, go to “Windows Azure Platform” then click the “Subscriptions” tab and on the right side, you’ll see a drop down with different “Actions” into it… Choose “Opt out of auto renew” and, NOW you’re safe…

Still, this is a great offer by Microsoft and I think everyone that has a chance should play a bit with Azure to get to know this technology a bit more...

Happy Cloud Computing All

Yesterday I gave a conference on LinQ to Objects at the .NET Montreal Community. The format was not your typical conference, it was a coding dojo!

Everything went well and I think many people enjoyed to event. I'm posting a link to the solution that contains all the exercices the group did with the the answers included. Unfortunatly, it's in french :) If someone would like to have the exercices in english, about 20 of them, please post a reply and I'll put the english version here ASAP...
