RE: WPF Application with Caliburn - Part One

Mickey — Mon, 01 Mar 2010 07:43:01 GMT

Hello,

I had difficulty following you tutorial:

1. You have not which .dll to reference, so I had to try out referencing different .dll-s to have my project compile.

2. Same issue was with DelegateCommand. It was not clear that I had to find its implementation somewhere else.

3. The program was throwing an exception "Cannot set Owner property to itself." in DefaultWindowManager class, EnsureWindow method. After rechecking and examining you code I saw, that in "Marying View and ViewModel" you instructed to create ShellView as UserControl, but in "Binding" and in your code it was Window class.

Overall the tutorial was helpful.

Thank you.

RE: Code Review No. N, or Do chimps write code better than us?

Chuck Conway — Sat, 27 Feb 2010 18:59:24 GMT

Sadly I've seen code like this before. I'm currently on a project that was initially written by a team of junior programmers. The code is written almost exactly as the samples you provided. Anti-patterns include dataset and datatable methods (just the fact they are used is a huge anti-pattern, in most cases), if statements around optional database parameters, using partial classes as object orient design and procedure names as enumerations.

If your application works, that's more than I can say about the application I work on, on a daily basis.

Unfortunately, the source file and pictures of that post were lost during transferring from my previous host. New Caliburn releases is way better than the old ones and provide much more, so why not upgrade?

By the way, I want to suggest another book which is absolutely great:

Hi Hadi,

this article is a great help to get a better understanding how caliburn works.
Unfortunatly I have to work in to a project which used an older version of caliburn.

I saw your older article from 2008 which covers that version, but the link to the source is dead.
(also the links to the pictures are dead)

Is there a another way to get that source?

Thank you in advance!

Kind regards

RE: BiDi applications with Silverlight 4

Parham — Mon, 18 Jan 2010 09:20:39 GMT

ولی من با ورژن 3.5 مشکلی ندارم و همیشه از فونتهای فارسی وب استفاده میکنم (معمولا نازلی). تو ورژن ۴ با این مشکل روبرو شدم.

متاسفانه من با فونت های "فارسی وب" هم با ورژن 3.5 و هم با ورژن 4.0 مشکل داشتم! ولی هر دو ورژن با فونت های "برنا رایانه" که با ورد هم درست کار میکنند ، کار میکرد. با این فونت ها تست کنید

در ورژنهای قبلی این مشکل نیست.

RE: BiDi applications with Silverlight 4

Hadi — Sun, 17 Jan 2010 11:57:17 GMT

Hello,

I had a problem with "Yek" character only when page was displayed in Firefox (IE worked fine). I used Tahoma font (standard windows font) to test it so it might not work with other fonts. I've reported this to Microsoft team working on Silverlight Bidi, and apparently, it will be fixed in final release.

For FarsiLibrary runtime that works with Silverlight, there are some problems, mostly because Silverlight has no PersianCalendar and because of this some Parse methods on PersianDate class will not work. However I'm working on it. You can get the source for SL version from a branch on GitHub (http://github.com/HEskandari/FarsiLibrary/tree/silverlight).

RE: Caliburn = Less Code?

Hadi — Fri, 15 Jan 2010 12:11:26 GMT

@Johan:

That's the whole point for Caliburn framework; to provide a framework that works seamlessly on Silverlight and WPF. Although there are some differences that are more related to different nature of WPF and Silverlight, Caliburn works almost the same in both presentation layers.

The new post series contain a sample application developed with Caliburn. Check it out.

RE: MVVM Validation With NHibernate Validator

Hadi Eskandari — Thu, 14 Jan 2010 05:57:43 GMT

Brendan, I thought everybody knows what RelayCommand is, since it's been around for quite some time. It is an implementation of ICommand interface, and the Notify method is actually an extension method I mentioned on my earlier blog posts. Try searching for "RelayCommand" and "INotifyPropertyChanged" keywords in the blog search and you'll find your answer.

RE: MVVM Validation With NHibernate Validator

Brendan Rice — Thu, 14 Jan 2010 00:05:52 GMT

Thanks for the solution it looks exactly what I need. I tried to piece together the code but there are a couple of things that didn't work for me: 1. NewAccountViewModel.Firstname - this.Notify(this.PropertyChanged, o => o.Firstname); !!This Line doesn't work I get red squigglies where does the Notify method come into it?!! 2. NewAccountViewModel.SaveCommand _cmdSave = new RelayCommand(Save, CanSave); !!There is no mention of a RelayCommand in your article where does this come into it!! Would it be possible to post a working solution to see where I am going wrong? Thanks again... B

RE: RightToLeft in DevExpress Controls (DXperience)

Hadi Eskandari — Mon, 11 Jan 2010 06:57:15 GMT

Abdullah, Mohamed Salah, The change is in the source code of DevExpress components. It is tremendous amount of work, not just changing a few lines of code. Furthermore, I can not send you the code, because the version I worked on is old (a build for 2006) and send you the source code of DevExpress is against the copyright. If you're working on a new project, try DevExpress WPF controls. Thanks to WPF engine, the right to left layout is working great.

RE: Entity Framework 4 - Part Three : Repository Pattern

Hadi Eskandari — Sun, 13 Dec 2009 06:59:26 GMT

Jose, Support for IQueryable is easily added just by implementing the IQueryable interface and delegating the interface calls to the IObjectSet. The reason I didn't do that was to keep things simpler.

RE: Entity Framework 4 - Part Three : Repository Pattern

José F. Romaniello — Sat, 12 Dec 2009 12:22:49 GMT

Sorry, the parameter is Expression of Func of TEntity and Bool.

RE: Entity Framework 4 - Part Three : Repository Pattern

José F. Romaniello — Sat, 12 Dec 2009 12:20:13 GMT

IMHO this is DAO pattern. A truly repository is one that implements IQueryable like this one: http://digg.com/u1C649 Fawler say: "A Repository mediates between the domain and data mapping layers, acting like an in-memory domain object collection." I like the Dao pattern more than Repository pattern. I use in the same way that you with some specification class. My FindOne and FindMany has Expression> as a parameter. Then I use in this way: dao.FindMany(CustomerQueries.HighProfileCustomers()) Also sometimes I use parameters: dao.FindMany(CustomerQueries.HighProfileCustomersAtPeriod(DateTime.Today.AddDays(-15), DateTime.Today));

Christoban, Unfortunately, that post is related to pre-beta version of Caliburn and it may not even be valid for the RTM version due to lots of changes and change of route in Caliburn framework. The pictures were lost in process of changing my hosting provider and since the content is outdated, I even don't have the binaries to reproduce them. There are some new caliburn tutorials on the internet which I'm sure you find useful.

RE: RightToLeft in DevExpress Controls (DXperience)

HEskandari — Wed, 16 Sep 2009 20:09:59 GMT

DevExpress is not alone in this case. Some components of ComponentOne have the same problem. I used ComponentOne for several years. Report Component is the best around the world but RTL is not supported in both windows and web version.

RE: RightToLeft in DevExpress Controls (DXperience)

HEskandari — Wed, 16 Sep 2009 20:09:59 GMT

Actually, I have worked with C1 report. Although it has some shortcomings with RTL, I managed to make it work with some workarounds, in an enterprise Web application using ASP.NET, and also some WinForm applications. With all the problems of C1 with RTL, IMHO it is still the best there is to be used in RTL oriented applications.

RE: RightToLeft in DevExpress Controls (DXperience)

HEskandari — Wed, 16 Sep 2009 20:09:59 GMT

Dear Hadi,
Did you change the source code of DevExpress to make some components support RTL?

Thanks

RE: RightToLeft in DevExpress Controls (DXperience)

HEskandari — Wed, 16 Sep 2009 20:09:59 GMT

Hi,

I've changed the DevExpress sources in order to do so. That's the only (decent) way to do it. The only problem is that you need to do it all over again when they release a new version.

RE: RightToLeft in DevExpress Controls (DXperience)

HEskandari — Wed, 16 Sep 2009 20:09:59 GMT

Hi, How did you do it ??

RE: RightToLeft in DevExpress Controls (DXperience)

HEskandari — Wed, 16 Sep 2009 20:09:59 GMT

Hi Hadi

Interesting stuff!

We have been using DevExpress controls now for a couple of years and now have an opportunity to sell into the middle east market and so really need RTL support. However, a recent email to DevExpress has once again confirmed that there is little chance of RTL support being included in the near/mid future.

I can see that you managed to change the DevExpress code to support RTL for some controls, and whilst having to change their code is not something we really want to do, I'd be interested to know how easy you found it and the sort of timescales involved

RE: RightToLeft in DevExpress Controls (DXperience)

HEskandari — Wed, 16 Sep 2009 20:09:59 GMT

Chris,

In a matter of 3-4 weeks I could manage to fix RTL issues in all controls resided in Utils and Editors projects. By doing this, other projects such as Grid partially supported RTL because they inherently reused existing corrected functionality. Working on Grid control can get much hairy as it is more complex.

With their latest release and rearcitechture, I think there MIGHT be ways to do this without touching their code (by subclassing the controls and replacing the drawing parts).

Hope this helps

RE: RightToLeft in DevExpress Controls (DXperience)
