I just have the MSDN subscription Azure and I have just signed up to the

Except that after billing my credit card the sign up process dumped me with

Specifying a chat interface as a way of getting clarity on a UI design

[kirsten greed]

Hello

I was with a team of designers yesterday, as the api contact person.

We seemed to be talking in circles a bit, sort of particles vs waves ( as I
recall in Physics)

My client and I once tried BDD but we found talking in cucumber did not
come naturally (Although there were some benefits)

It occurs to me that specifying a chat interface would be helpful in the
application design phase even if we do not implement it.

For example

"Computer
Find the order we did for Harry around September Last Year
Create a quote from it
Add 10 widgets with the blue thingame"

Does anyone have experience or thoughts about this concept?

Thanks
Kirsten

Thoughts on Web Assembly and Blazer

[kirsten greed]

Hello

Is anyone out there using Web Assembly and Blazer for real projects?

I just spent a couple of days trying to get the code generated by Visual
Studio's AutoRest add in  to work with Bearer token security.

It turns out that the Autorest project on Github has moved on from that old
code and done a big re-write

Greg's blog at
https://gfkeogh.blogspot.com.au/2018/02/im-in-future-of-web-and-it-doesnt-work.html

back in February did sum up everything eloquently in my view.

Is anything better out there yet?

Thanks

Thank you, Stephen
I have it working at last after browsing through that document and others
I was  tripped up on setting the application pool, I had not realised it
needed to be No Managed Code.
I wound up having to install the C++ redistributables ,
and copying over the documentation xml file that my project was generating.
I felt like I was stumbling around in a dark house with lots of rooms and
stubbing my toes on everything.
I guess I know the layout a bit better now.

Deploying .Net Core 2.0 to IIS running on Windows Server 2012R2

[kirsten greed]

Hi folks

I am wondering how best to  test deploying my .Net Core 2.0 Api

The production computer is running Windows Server 2012R2, so I thought I
would try testing on an Azure VM.

When I tried to do this I found myself led into the Marketplace to use an
image from CloudHubTech with the cost not being covered by my MSDN Azure
credits.

This causes me to pause and wonder if Docker might be a better way forward.

Any wisdom on how I should proceed would be appreciated.

Thanks
Kirsten

Re: Class diagrams and tools for communicating with clients

[kirsten greed]

I  am half way through the Scott Wlaschin Video which makes a great case
for F# as a DDD tool.
I love the Card Game example.

module CardGame =
 type Suit = Club | Diamond |Spade : Heart
 type Rank = Two  | Three  | Four  | Five  | Six   |  Seven   |  Eight   |
Nine   |  Ten   |  Jack   |  Queen   |  King   |  Ace

type Card = Suit * Rank
type Hand = Card list
type Dec = Card list
type Player = {Name:string; Hand:Hand}
type Game = {Deck:Deck; Players : Player list }
type Deal = Deck -> (Deck *Card)
type PickupCard = (Hand * Card ) -> Hand


As Scott points out the customer can easily see if I missed a Suit or a
Rank. The code and the design are one and the same, and persistence is not
mentioned.

Regarding UML, I never really came to grips with it in the past.
I just watched parts of the Pluralsight course : Picturing Architecture:
UML (The Good Bits) and More by Allen Holub which helps a bit  However if I
find UML a learning overhead, how can I expect the customer to be able to
speak it with me?

I will check out the Simon Brown link too. Thank you.

Re: Class diagrams and tools for communicating with clients

[kirsten greed]

Rather than drawings to code, I want C# code to diagrams.  I had a play
with Resharper's Type Dependency diagrams but the result is more for
programmers.
I need something that displays a class in a form that promotes discussion
in the "Ubiquitous Language"

For Example a Car with four Wheel properties.

Class diagrams and tools for communicating with clients

[kirsten greed]

Hello all.
After revisiting "Domain Driven Design"
I want to try using class diagrams to communicate with my client.
However my classes are cluttered with internal properties that are not
relevant to our conversations

I thought of trying interfaces for example


public interface ISnapInModel
{

IBlank Blank { get;  set;  }
}

public interface IBlank
  {
public int Height {get;set;}
public int Width {get;set;}
  }


However when I try to create a class diagram in VS2017 no association draws
between the two interfaces.

Is there a better way?
Thank you

Re: Using Azure blob storage for static web sites

[kirsten greed]

Thanks Greg

I have it working at last :-)

In DNSMadeEasy

I made a CNAME record with name=docs Alias to
myblob.website.blob.core.windows.net  ( i.e mapping to the storage account
in Azure)
then I made a redirect for www to http://docs.comeandcode.org.index.html
So now
www.comeandcode.org opens the index.html to say "hello world"

Re: Using Azure blob storage for static web sites

[kirsten greed]

Greg,
I am having a play with DNSMadeEasy
I think the catch might be that your method needs a sub-domain.
and www is already needed for the Azure  mapping.

Re: Using Azure blob storage for static web sites

[kirsten greed]

Is the storage public?
I get
This site can’t be reached

*kirsten.sqldownunder.com <http://kirsten.sqldownunder.com>*’s server IP
address could not be found.


   - Go to http://sqldownunder.com/
   - Search Google for kirsten sql down under

Using Azure blob storage for static web sites

[kirsten greed]

Hi folks

I am investigating using Azure blob storage and CDN to host a static
website with a contact form because this provides low cost hosting and ssl.

I have managed to get the site working but with the following limitations

1) I am yet to map the domain directly to an blob.
ie the user has to go to https://www.mydomain.com/index.html  not
https://www.mydomain.com

I gather Microsoft plan to fix this this year

https://feedback.azure.com/forums/217298-storage/suggestions/6417741-static-website-hosting-in-azure-blob-storage

I have googled some workarounds involving Azure Functions or CDN Rewrite
rules but am yet to try.


2) How to do a Contact form that emails me on submit.

I have seen some advice at
https://stackoverflow.com/questions/9533172/adding-contact-form-to-a-static-website


I am wanting some advice on how to proceed.  I don't mind a bit of a
learning curve as long as the learning is not going to be redundant in 6
months time.

Maybe I should just do a web app with Cloudflare for ssl ( which I have
done before)  and wait.

Thoughts and experiences?

Wondering about the colours though - they're presumably based on the
Microsoft logo colours. Would it be better to have them in the same order
(eg. clockwise from top-left red, green, yellow, blue) ? Or is it
intentional to not do that to avoid legal issues? Or maybe have them upside
down as a nod to being 'down under'?

#6 is the best f those presented.  Some suggestions: 
- I think "oz.net.com" is just unclear.
- We probably don't need the ".com" as part of a logo.  The actual website
can be additional text below the logo on any promotional material rather
than part of the logo.
- Did you try "ozdotnet" on a single line?

My daughter, Katie, has given me a few logo designs based on what I asked
for. 

 

Plan is to put this on the website/forum (if/when that goes up) and make
stickers and tshirts available (probably RedBubble). Turn it into something
people can promote and get a bit of new blood. 

 

Feedback welcome.

p.s. personally I like 06, but have asked if she could have white text with
a black outline (to make it easier to read). Also liked the OZ characters
being slightly larger.

If you're getting a new box, then get 16GB++ of RAM (it's cheap) and you can
run multiple VMs easily. I use VMWare player. You should never suffer slow
loading of VMs, for me they're as fast to load and run as the native OS.
I've haven't used Docker yet. My advice: Only install what you really need
for daily working on the metal machine. Any alternate versions of things, or
things to evaluate, or hobby things go into VMs. I try to keep my work OS as
clean as possible.

A fresh Win10 install has tons of garbage installed and running. After my
last install I spent 3 hours removing and disabling junk everywhere (only
Flash has defeated me, I can't remove it, just disable it).

Tl,Dr : Yes. Cross platform Docker is still in its infancy. Ditto GUI apps
on Docker.

The Docker Toolbox for Windows, and now the Docker Windows 10 integration
(RTM) allow you to run Docker containers *for Linux* (the Toolbox via a
hidden VM, and the Windows 10 native version presumably via the Windows 10
revamped UNIX system). There is a preview version that includes Windows
Container support, but I've not tried that yet. It seemed simpler to install
SQL server *for Linux* in the container than work out how to do that. Go
figure. I also use Oracle Express the same way.

And Docker support for GUI apps is also not really a thing. It's discussed
in the Linux world, approaches exist (x11 forwarding[1] or VNC), but
definitely not the norm. Doesn't seem like Windows Containers address this
either, at least not yet. It will happen though.

So VMs, virtual desktops or bare metal setups are probably still the go for
IDEs, but I'd definitely attempt to Dockerise any services I was dependent
on as and when I could, and deploy to Docker if using .Net core.

(As an aside, Docker support for multiple architectures is also a work in
progress, the registry just assumed everything is x64 (whereas Docker on Pi
is Arm of course))

VMs and Docker are great for isolating things.


Also now with Windows 10 being able to do a 'refresh' (leaving all your
documents and source files etc alone) combined with something like
Boxstarter (or even just Chocolatey), being able to rebuild your machine can
be done relatively painlessly (eg. a few hours, or overnight). I do like the
idea that recreating my development environment is pretty straight forward.


Do watch out for having too many versions of SQL Server installed - it can
end up making your PATH environment variable too big and then "bad things"
start happening.

Try deleting the httpmodules section in your web.config file  for the

Yes it is possible to have two websites sites running under IIS with one
using Classic and another using Integrated.

 

Firstly make sure you have two application pools. One for Classic and
another for Integrated. By default, I think they have them listed. But you
can create more so each web application on the IIS server can have its own
worker processes.

 

I would then setup the website as the root of Default Web Site. Configure it
to use the Classic application pool. This way you don't have to bother with
URL Rewrites.

 

Then create a child application for your web service as you have already
done so. Configure it to use the Integrated Application pool.

 

That should be it.

I was unfamiliar with the Mercury browser too. Not sure what tech it is
based on, but by the Play store's metrics it has been downloaded between
500,000 and 1,000,000 times. This sounds like a lot, but then you look at
the numbers and see that Firefox has been downloaded between 100,000,000 and
500,000,000 times. Unless your metric show a compelling reason to do
otherwise I wouldn't support boutique 3rd party browsers.

It would be worth checking to see if the android 'built-in' browser (which
is not Chrome) supports this, as it is likely much more widely used.

RE: [OT] Noise cancelling earphones for a quietprogramming environment?

Thank you all who replied about this post.
 
I finally picked up a Bose QC15 from the shop at Camberwell junction, on
special at $359
Although they don't drown out hubby tapping the keyboard in the background,
they make me feel as though I am in a different room.
 
We had a very bad experience on line at ValueBasket, cancelled the order
after waiting a month and they only refunded after we raised a credit card
dispute.
 
Apparently there are a lot of counterfeits on the market - so if you plan to
buy one, check with Bose that the dealer is authorised.

+1 for the Bose gear. I wear them all the time on long flights and love them
but have also used them in other environments and they are great.

 

The noise reduction quality is amazing. 

 

+1 also to the idea of drowning out part of the other noise. While they work
well without anything even plugged in, clearly you'll lose the other
distractions better if you have sounds of your own.

 

For the same reason, I often will have the TV, or music, etc. on when I'm
home alone working just to provide background noise. Otherwise, every little
sound seems to be distracting.

can't hear that either - YMMV of course - if you go to the bose store
they're pretty good at helping you test for your situation, especially at
that price tag. I had the guy do loud sniffles for me so I could see if it
worked for that:

[OT] Specflow

Hi All
 
Not sure if this is OT or not, but is anyone using Specflow?
I am wondering if the practice works in reality...

RE: [OT] Specflow

[Kirsten Greed]

Thanks Jason
 
I think I want the business readable stuff to be done first rather than
reverse engineered or  would it be the same thing in practice?
 
From the website..
SpecFlow aims at bridging the communication gap between domain experts and
developers by binding business readable behavior specifications and examples
to the underlying implementation.

I am curious to see if anyone actually manages to use it to achieve this
lofty goal.
 
It seems to me that the largest part of the battle would be getting the
story written in Gherkin in the first place.
 
I tried selling the idea to my client but he felt that it would be too hard.
Cheers
Kirsten

Hi Kirsten, it’s worth mentioning that you don’t need to use SpecFlow to do
UI automation if you don’t need that business-readable representation of the
tests/scenarios. If the test are just for the devs/automation testers then
may be able to do without the additional layer.

Also check out BDDfy http://docs.teststack.net/bddfy/index.html it lets you
create business readable living documentation from your tests, as opposed to
writing the tests in business readable language and then implementing the
test steps (as with SpecFlow).

If you’re doing UI automation then you may want to consider page object
models as your tests size/complexity grows - just wrote an article about:
http://dontcodetired.com/blog/post/Using-Page-Object-Models-in-UI-Test-Autom
ation.aspx

Light weight, over the ear would be best.

Sorry I do not think I am going to be a lot of help here.




Recommendation: The best thing to do is to get out of the open office
environment, I find that I am greatly affected by background distractions.
I have had five fold productivity increases when working from home or in
some other comfortable place away from the mad office.




If that fails, I have used Bose QuietComfortR 15 Acoustic Noise CancellingR
headphones
(http://worldwide.bose.com/axa/en_au/web/quietcomfort_15/page.html) which
are great at cancelling out the background road sounds on the bus, but
pretty useless at the higher frequency office sounds.  See
http://en.wikipedia.org/wiki/Talk:Noise-cancelling_headphones#Real-world_per
formance_of_noise-cancelling_headphones for a discussion on this.




The best solution is that everyone has a work cubical with a lot of sound
deadening material and meetings happen in meeting rooms, not at desks.

Same rule applies don't autobind. You end up with 1-5 connections open on
the database. Do your own mapping and binding away from the EF objects.

If you don't make the break from the bound objects, you have to deal with
objects that have been disassociated from their context and are stale.

As ever datalayer is for connecting to the database and translating to and
from your private objects.

 Hi Ian,

 Just an idea which came to me, not sure if it is much use (at least in the
 short term), but it seems like a game similar to tetris (maybe even a
 simpler version with only 3 or 4 shapes) might be good for testing
reaction
 times. You can graph the average response time from when a shape appears
to
 where it is placed, and see how it goes as the game gets faster. Obviously
 this will not give good results after one game (because reaction times
will
 also depend on what shapes you have at the bottom and ability to problem
 solve), but I think the data gained over the longer term can show trends
and
 averages/etc.

 Also maybe a game that shows you three images, where two are the same and
 one is different, and using left, down, right on the arrowpad you need to
 select the one that doesn't match. You could once again keep the data and
 graph this over the long term.

Even Pong could be used this way I guess



 Anyway, good luck, and I'd be interested to here any progress.

RE: Making an application that uses identity keysoccassionally connected

[Kirsten Greed]

Thanks Greg

I get the point about saving the round trip!

 

I am starting to hope I can use my existing database structure replicated at
each site, with some kind of mapping system hosted in the cloud

The mapping table would be something like

 

GUID  

SiteID - one for each installation

TableID  - one for each table

PKIntID   - the identity field for the record at the site

 

Is this what you were talking about when you said 
The other main thing is that there often seems to be a presumption that you
have to have your logical data model the same as your physical data model.
You don't.
For example, rather than having all your tables that have a customer ID
having the GUID, you can always have ints or bigints all over the place, and
just have one table that maps between them. ?

Does SQL Server have some sort of in built process we could piggy back?

Hi Greg,

 

The point I was making is that the main reason for using GUIDs is so that
the code that creates an object can assign an ID to it without having to
reference a single allocator for IDs. I could have five servers and four
apps and they can all happily create values and related objects that will
then be able to be thrown into a single database some time later. 

 

This gets even worse where you have queues involved. The code generating the
object might not even have access to the database. With a GUID, the code can
generate an ID, then ship it across the queue to some other system to
process it.

 

Any ID generated by database misses the point. To use them, I usually run
off to the database to get an ID before I continue. If I'm going to do that,
what's the advantage of getting a NEWSEQUENTIALID rather than just an INT or
BIGINT? It's just uglier for no benefit.

 

The main aim of using GUIDs is to avoid being tied to some server that's the
source of all IDs, and having to incur round-trip costs to it.

 

Regards,

Noonie says his DBAs rejected them (why?). Tony hates looking at them in the
debugger (that's not a convincing argument for me). Greg L says you might as
well get an INT instead (more details?).

 

I hope you'll agree that there are times when you want to give rows an
immutable primary key. Will you also agree that an IDENTITY INT is not
immutable because it can change when rows move across databases or when rows
are reorganised or reloaded. If this is so, how on earth do you stamp your
rows with an immutable key without using something like Guids?

Tony mentions 

 Of course, because you can synchronise with the single-source-of-truth in
a batch anyway, both have strategies that will work. If you choose guids, I
think you need to separate out the data that you're adding from the client
vs reference data, so you don't make the mistake of implementing guids for
all tables, or ints for all tables and allowing clients to add reference
data using the same mechanism when it is unnecessary or even undesirable.

 

And Greg Low mentions on SQLDownUnder

 

 The other main thing is that there often seems to be a presumption that
you have to have your logical data model the same as your physical data
model. You don't.

For example, rather than having all your tables that have a customer ID
having the GUID, you can always have ints or bigints all over the place, and
just have one table that maps between them.

 

I am having trouble thinking through how this would work.  Does this
solution use a framework like the sync framework ?

The scenario is a business application (customers, sales, inventory etc) but
users will want it to work the same wherever they are.

 

Greg Kennedy thinks that the sync framework will cracks a fruity if the
guid is not the Primary Key. ( see his email  sent Sat 11:28 am elaborating
on this)

I find that these sorts of discussions often come out of standardisation
meetings where people say stuff like should we make all our primary keys
guids or ints then make a broad ruling and dev teams have to live with the
consequences. Remember that one size does not have to fit all. 

 

Of course, because you can synchronise with the single-source-of-truth in a

all tables, or ints for all tables and allowing clients to add reference
data using the same mechanism when it is unnecessary or even undesirable.

 

I don't need to repeat performance issues info about guids, but I have one
more comment to make that many people overlook, and that is:

 

From a developer's point of view, GUIDs suck. 

 

With guids, if you have your query analyser window open and want to run a
quick query on a table to get a particular row, you have to have a valid
guid, which means you have to look up your guid then copy or rewrite whole
guid string into your query. Far more prone to errors. Therefore, with
Guids, cutting and pasting is necessary most of the time. 

 

With ints, it's really easy, because you can often remember the ids of
reference data after a while. With ints, most of the time, no cutting and
pasting is necessary. It is far easier to remember an int when crossing
between development and debugging in the query analyser. It's far easier
when you're profiling to see an int and type it straight into a query on
another screen.

 

Also think of keystroke analysis and how much extra you need to do to work
with Guids, such as requerying the database because it's too hard to
remember a guid, identifying the record you want, honing the mouse, copying
the guid, selecting your destination window, honing the mouse over the
destination query, pasting the guid in the correct location. All of that
instead of using a simple int!

 

So if you want your team to be more efficient in their development, work out
a strategy using ints and enjoy your jobs a little better.

The problem with NEWSEQUENTIALID is that it fixes the wrong problem.

 

One of the main reasons for using GUIDs in the first place is so they can be
generated in other layers of code (and potentially other servers) and then
just thrown into the database. If you are going to the database to get a
GUID of any type, you might as well get an INT instead.

Hi Greg ,Greg ,Greg, David, David and Heinrich

I am worried about the performance issues this could create.
Some of my queries go 5 tables deep or more, up till now an int primary key
has seemed like the best performance option.

The idea of adding a sync only guid key is appealing to me however I am

Does anyone have more info about this?

Any chance you can use a compound key? Where the client that creates the
record has a fixed key and an auto increment key. Together the keys
would be unique. You can also tell where the record was created.

Hi Kirsten,

 

From my experience, using GUIDs as surrogate primary keys works fine in
development where sample data is only thousands of rows. It bites viciously
in production where we have millions of rows and deep dependencies. Int keys
are still surrogate keys but seem to offer better performance.

 

How you do this will depend on what your occasionally connected applications
are connecting to. If it is a reporting database that consolidates data from
different sites then your solution would be simpler than where it shared the
information across all the remote sites.

 

All the suggestions mentioned, in this thread, are viable. I have used
two-part keys (e.g site-id, item-id) in the past to good effect. More
recently we have added non-key GUIDs for the central database to verify
equality and, as we don't redistribute all the data to the remote databases,
it's only used as a tie-breaker.

 

The solution you choose will depend on the nature of the application and how
much sync code you are willing to write. If you use a framework you are as
much constrained by its limitations as you are freed from having to write
code :-(

Kirsten,

 

One issue with GUID keys is that they are not one-up so with clustered
indexes base on a GUID, inserting new records into a table typically can
cause a page split, which is expensive, there is a different algorithm to
generate a GUID that is always increasing so it acts more like an integer
key.

 

In SQL 2005 and above it is NEWSEQUENTIALID() and there is code to generate
it in .net I think.

 

Good article that compares all of these key types:

Quite good timing actually, here is a post which backs up my point about
staying away from unity if you want a well performing app:

 

http://philipm.at/2011/0808/

 

Another negative side effect of Prism is that modules have a single Run
method. Which you have to do your container registrations and resolve your
dependencies.

 

Internally when you resolve, if you have performed any registrations since
you last resolved the container has to rebuild it's dependency tree, which
is costly. Autofac forces you to create a ContainerBuilder then build the
container from that, so you mentally separate registration and resolutions,
this has the advantage that Autofac does not have to lock the container when
you perform a Resolve, reducing contention and once again speeding the
container up. Unity has to lock on all operations.

Yes, I thought the posts were worth reading. Attaching the EF Profiler was
the first that I saw, and is super-simple. 
All of Ayende's (blogged) testing was done in the month of August, 2010 - I
searched carefully for something near the RTM time, but no. Perhaps in
future.

Hi Ian,

There's some good posts there such as attaching the entity framework
profiler, but it's also worth remembering those posts were based on Beta 1
or there-abouts.

RE: Lightswitch - really clever - really slow

Hi Ian, Bill, Peter n All

I found the post you mention and opened the end project of the lab   (
actually I should have just done that in the first place )

The app runs at an acceptable speed - but then it has no existing data and
the entry forms have only a few fields!

Curious, I did search for that particular application, and there was a forum
link
http://social.msdn.microsoft.com/Forums/en-US/lightswitchgeneral/thread/20b
e9371-736d-487b-9dd8-57d8d92303cf  suggesting XP was not suitable - Your
current OS is not supported by the lab

So that person edited a dependency file, which fixed the problem.

He refers to a Configuration Wizard in the Training Kit. That must be run
first, apparently.

However, that forum chat was a year ago and the RTM may be quite different.
I haven't installed and played with LightSwitch (enough problems with JSON
data to keep me perplexed, yet again).

RE: System.Data classes and ListT

Subject: RE: System.Data classes and ListT

 

Chaps, your comments are interesting and perhaps make me feel not so guilty
for using System.Data classes in these modern times.

 

I've only used netTiers and EF4 in recent years, but deep down they all run
a SELECT statement, loop through the rows and move the columns into
collections of objects with matching property names. In the early .NET years
I wrote my own code to do that, and I know VB6 developers who are still
doing it.

 

The classes and collections returned by netTiers implemented all of the
interfaces I like in System.Data. The EF4 equivalents do not seem to. So
where does that leave me? I fall back to the convenience of System.Data
and I feel guilty, but perhaps I shouldn't. Maybe no one is game to admit
that EF4 is a bit immature.

 

I've had no reply from the EF4 MSDN forum yet.

 

I will continue to send DataSets to pick lists and grids in my UI. However,
I do perform updates and deletes using the EF4 entities and context, and I'm
reasonably happy with the way it works. It's tedious to eager load an entity
with non-tracking, send it up to the UI, edit or delete it, then attach it
back to the context and call ApplyCurrentValues on all the entities before
saving it.

 

netTiers is not regarded as a big player in the ORM field, but my experience
so far is that netTiers is generally better than EF4 because its entity
classes and collections are completely self-tracking, and most importantly,
there is no concept of a context. The only reason I'm learning EF4 and using
it is because it's the latest greatest thing. I guess marketing does work!

Hi Davy

 

Are you saying the following is bad code?  

Aren't I binding to the output of the ORM rather than the data directly?

What would you advise ?

I am using winforms and Entity Framework

 

ListspCustomerSelect_Result custs = context.spCustomerSelect(where c.type
= 1 ).ToList();

gridview.DataSource = custs;

It's never been a good idea to bind databases direct to output.

Mvc / mvvm etc are attempts to remove code from behind the events of the
screen. The idea being that you can use different views with the same
presenter / controller. It's fun to code, pain in the arse to debug. But
does allow you to unit test it.

I like mvc, mvvm I'm not so hot about.

Chaps, your comments are interesting and perhaps make me feel not so guilty
for using System.Data classes in these modern times.

 

I've only used netTiers and EF4 in recent years, but deep down they all run
a SELECT statement, loop through the rows and move the columns into
collections of objects with matching property names. In the early .NET years
I wrote my own code to do that, and I know VB6 developers who are still
doing it.

 

The classes and collections returned by netTiers implemented all of the
interfaces I like in System.Data. The EF4 equivalents do not seem to. So
where does that leave me? I fall back to the convenience of System.Data
and I feel guilty, but perhaps I shouldn't. Maybe no one is game to admit
that EF4 is a bit immature.

 

I've had no reply from the EF4 MSDN forum yet.

 

I will continue to send DataSets to pick lists and grids in my UI. However,
I do perform updates and deletes using the EF4 entities and context, and I'm
reasonably happy with the way it works. It's tedious to eager load an entity
with non-tracking, send it up to the UI, edit or delete it, then attach it
back to the context and call ApplyCurrentValues on all the entities before
saving it.

 

netTiers is not regarded as a big player in the ORM field, but my experience
so far is that netTiers is generally better than EF4 because its entity
classes and collections are completely self-tracking, and most importantly,
there is no concept of a context. The only reason I'm learning EF4 and using
it is because it's the latest greatest thing. I guess marketing does work!

If I go to seek.com.au and type in Nettiers I get no results.  Entity
Framework gives 97 jobs in Australia

Are there features EF has that Nettiers doesn't?

I am wondering if these days the done thing is not to bind the output of an
ORM directly to the controls in the UI, but rather to have an intermediary
part of the UI between the ORM output and the controls

 

Both EF4 books I have mention this and hint that binding to entities or
passing them over service boundaries is not a good practice. For small apps
or maintenance utilities (I'm writing one now), editing entities directly
doesn't worry me, but when you start passing them over WCF or Remoting then
I'd consider using DTOs (Data Transfer Objects) that are custom views of the
entities. However, you then have to write more infrastructure to move them
around.

 

Is this what model view presenter / model view controller / model view view
controller are about? MVP/MVC/MVVC ?

Kirsten

 

Those patterns solve a different problem.

 

Your sample code where you bind the query results to a grid is fine for
small apps, but as you scale-up and have tiers, then it's impractical.

 

Nathan, I generally agree with your comments, but you need to write so much
more infrastructure. However, I'm still stuck with the limitations of the
features implemented by EF4 entities and collections. As a comparison, I
looked at some netTiers output classes and I challenge anyone to casually
knock-up classes that implements it's interfaces:

 

Generic Collection

ListBaseT : BindingListT, IBindingListView, IBindingList, IList,
ICloneable, ICloneableEx, IListSource, ITypedList, IDisposable, IComponent,
IRaiseItemChangedEvents, IDeserializationCallback

 

Sample Entity

FooBase : EntityBase, IMedia, IEntityIdMediaKey, System.IComparable,
System.ICloneable, ICloneableEx, IEditableObject, IComponent,
INotifyPropertyChanged

 

The System.Data classes implement most of these as well and that's why I
find them so convenient.

Hi Davy

Have you looked at EF4.1 Code first release?

I am wondering if it would alter your thinking on prefering Nhibernate for
new projects

Hi,

At the moment, at work, there are three projects running and the one that I
support.

Legacy app.
Uses datasets everywhere.
Pros.
Very fast, readonly application.
Cons.
Impossible to debug / modify, data is often loaded behind the scenes which
cause temporary database table locks 

.Net 4 with EF
Pros.
Developpers very engaged with the project, lots of sexy tech.
Cons 
It's been in development now for 6 months and very little visible progress
has been made. One screen is done with what ammonts to a single select *

.Net 3.5. Nhibernate
Pros
Works very well, transparent for ui developpers.
Cons 
Misconceptions with heriacical classes in nhibernate has made it impossible
to modify the data source. we have hundreds of work arounds to solve the
inheritance problems.

.Net 3.5 using datasets mapped to objects.
Pros.
Very easy to use, easy to maintain and add functionality.
Cons.
The code base is easily twice as big as the other projects

Personally, 
if I was doing a new website. I would use nhibernate

Web interface for existing database, ef.

Stand alone Application, ado datasets and map to objects. 

Davy. 

When all you have is a hammer, every problem looks like a nail. I feel
much the same way about xml

Subject: System.Data classes and ListT

 

Folks, I get the impression that the DataSet and its child classes classes
are falling out of favour, is that true? However, I personally find them to
be very convenient and full-featured for apps of all sizes (but I don't
expose them to the outside world of course and my discussion here is only
about private use). What I like about DataView and DataRow are the huge
number of interfaces they support, and for me the most important features
are these:

 

1. When bound to a grid you get bi-directional sorting with no code at all.

2. They supports SQL-like filter expressions (Foo Like '%bar%') AND (FooId 
666) for example, and applying these filters is blazingly fast.

3. IEditableObject in DataRowView gives begin/end edit semantics.

 

While coding lots of Entity Framework 4 over the last several weeks I often
have to materialize a collection of entities and send them up to the UI for
display in grids or pickers. The EF4 context only allows materializing T[]
arrays or ListT of entities, and these are woeful compared to DataView and
DataRow, they don't any of the three lovely features listed above.

 

I have resorted to converting my EF4 query results from raw DbDataRecord
back to DataRow so I get all the functionality back. Why do I have to do
this workaround? Am I missing some other technique?

 

Note, the entities and collections created by netTiers support all the
interfaces that the System.Data classes do, so it's only after migrating to
EF4 that I'm hitting this irritation. It seems that I'm taking a step
backwards with EF4 entities and hence doing stupid workarounds like
converting to System.Data objects.

 

I'm told there is an MSDN EF4 discussion group, so I'll ask about this in
there once I find it and get in.

Last night I found this:

 

Tracing and Caching http://code.msdn.microsoft.com/EFProviderWrappers
Provider Wrappers for Entity Framework

 

This chap (from Microsoft I think) has written a data provider wrapper which
intercepts all ExecuteReader, ExecuteScalar and ExecuteNonQuery calls and
traces what's happening. This makes perfect sense, but it's quite heavy
handed and I was hoping that there would be a more specific and lightweight
place to hook in, either in SQLite or in EF4. If I try this wrapper provider
out I'll let you know what happens -- Greg

BindingSource.Find with Entity Framework - NotSupportedException

[Kirsten Greed]

Hi All

Can anyone spot what I am doing wrong?

Thanks

Kirsten

 

BindingSource.DataSource = GetCustomers(); 

BindingSource.Sort = CustomerID;

BindingSource.Find(CustomerID, customerID );

 

Error message is 

NotSupportedException

This operation requires an IBindingList.

 

 

 

 

public ListCustomer GetCustomers()

   {

   var context = new jtEntity.Entities();

   var dbCust = from n in context.Customers select n;

 return dbCust.ToList(); 

}

 

 

 

 

 

  

 

 

RE: BindingSource.Find with Entity Framework - NotSupportedException

Hi Greg

I should have mentioned that I am playing with the BindingNavigator control
to implement a data entry screen, and a grid to implement a browse screen.

I want to click the grid and have the Navigator move to the record I
selected in the grid.

I thought BindingNavigator.DataSource.Find would be the way to do it, is
there a better way?

The generic List class does not implement IBindingList. I'm not sure who is
asking for the IBindingList, but it has to be the Find method. Ah yes, only
DataSet, DataTable and DataView implement it.

 

I think you're misusing the BindingSource. I usually put it between the
real data source collection and a control like a grid where it gives me a
bit more flexibility in UI binding. If you want to find certain Customers
that I'd search the actual List, not the binding source.

 

Customer cust = custList.Find(c = c.CustomerID == 666);

or

Customer cust = (from c in custList where c.CustomerID == 666 select
c).SingleOrDefault();
