thx, that thread deals on dataset versus other structures as Data Transfer Objects, and this is OK, but if the DAL in a remote host has to deal, say, with a typed dataset or a custom class or custom collection defined in the desktop (in an assembly who seats in a desktop, I mean), how can the DAL (in the host) get a reference to that????

Actually, the thread deals with defining the structure of the class in the datalayer (I know because I wrote that thread as well). Once the structure is defined in the DAL, then it can be made available across all the tiers. So, the DAL can populate the collection, and new entries can be added in the business layer and saved back via the DAL.
So, if you reverse your thinking, you start with the entity in the DAL and then this gets exposed to the business layer (and on into the presentation layer).
The beauty about this approach is that you remove the need to reference things such as System.Data in the front end, and as I stated in that thread you can expose this to other programming environments as well.

thx, letting the DTO live in the host, together with the DAL "it gets exposed to the BL and presentation layer"... but, how, if DAL/DTO and BL/PL are in different computers, only visible through internet?
thx

If you are using a webservice, the definition of the class (well a proxy version), will be added to the business layer when you add in a web-reference. This means that you can pass this back and forwards without worrying about it.

Hiya,
Not sure if you're still looking at this, but I came across a similiar problem where in the BLL and UI layers I had my own data objects that were hosted in the client or a webservice. Communication from the BLL to the DAL is remoting.
I didn't want the DAL to have any knowledge of these objects because these objects were "plugins" and the DAL could not possibly be able to reference the objects.
What I did was implement functionality to disassemble custom classes (in the BLL tier) into a generic object which was then passed into the DAL. All my custom classes inherit from a general object providing methods and properties to extract the data from the custom class, which helped disassemble the data.
Hope this helps
Cheers,
Ty

thanks, remoting is the answer I was looking for. Anyway, with framework 3.0 maybe the right way is to use WCF windows communication foundation that seems to combine webservices and remoting in a unified skeleton
thx

Hi All
Can someone share with me the architecture or Design for any large localization Web project which primarily publishes the content , I mean
something like MSDN help being localized to different languages.
Please suggest me how I can approach for localizing MSDN if I have all my resource files in XML format.
The guy in China should see in Chinese and in US in English , also
1)There are some security implications to be added like all content should not be seen in a particular page outside USA, only specific sections pertaining to that country should be seen in that localized language.
2)Can manifest of an assembly be useful in doing a dynamic way of localizing.
Any reference or suggestions with the pros and cons of the architecture is highly appreciated as this is a bit urgent need.

Whenever I've done this in the past, I've tended to create a table (say Article), with a subtable (say Content). The table structure tends to look like this:
Article
Article Id
article attributes
Content
Content Id
Culture Info
Article Id
Content
Then, you can serve up the content to the user based on their localization settings. If there is no content in that particular locale, then I work back up the tree. For instance, if the users locale is FR-Fr (French France) but there is no content where the culture info is FR-Fr, then I go back to look for FR. If there is no content in that culture, then I fall back to the default content (in my case, usually English).
Now, in your case, you might want to have another table called something like AllowedLocale which would contain the Culture Info that you wanted to allow. Be aware though, that the Culture Info is not foolproof. It is entirely dependent on what the user has selected at their end, so a user will still get access to your content if they have the same Culture Info set up at their end as you have allowed at your end.

If it is a design issue, yes. Whether to program it with one method or another, which is fastest, how to know what is fastest, etc.
If it is an issue specifically related to OpenGL, we don't really have a forum for it. Visual C++ might get you the answers you are looking for, or posting at another forum specific to OpenGL[^].

Those interested, Microsoft Architecture Journal issue 10 is now available covering such subjects as Composite Applications.

So why did you link to issue 9?

The link I gave was to the front page of this particular web site. Perhaps Microsoft have failed to update their front page to reflect the existence of this brand new issue which I received through the post today.

It's a good issue. I just wish they wouldn't use so many big words. Makes my head hurt to read some of it.

Regarding the article about data quality problems, do you accept the comment that it should be renamed as "Data Quality Deficiency Syndrome"? To me, it is starting to sound almost like some kind of medical diagnosis.

According to an email, the 10 issue on line is just a preview offered to current subscribers, so maybe they have not updated to 10 on the site as they have not officially released it?
Our developers never release code. Rather, it tends to escape, pillaging the countryside all around.

As stated above, Microsoft haven't updated their architecturejournal.net web site. The publication most definitely exists. How could I have made a reference (above message) regarding the content of the article on data quality without the actual publication being in front of me?

Ok,
I havnt gotten mine yet, just recieved an email last week stating that you could get a peek at the online content before the mag got shipped.

Hi All,
We are starting a project (.NET/C# DB: SQL Server) and one of the main requirements is performance and reliability (the system is a "mission-critical" one).
Could you please indicate articles/books/sites that could help us on:
- Defining the minimum hardware requirements (how many redundant servers should be considered, RAIDs, etc.) based on the expected number of user/requests,ammount of data etc.
- Technologies that could be used in order to support the desired reliability ( distributed services, load balance for example)
Thanks a lot,
Sergio

Hi,
I have to develop a application which have many forms. Every form have datagridView , Dataset.
I want to put out of the code of my form, the operations of filling the dataset and displaying the datagridview ... The question is which Design pattern should i use???
Strategy pattern or Builder???
Thank you for your answers and sorry for my bad english

There are many ways to write something, so the choice isn't always obvious. But that also means the choice is not always one or another, and certainly not without knowing more of the design considerations.
Take your design needs/goals and compare them to the various design patterns. Some will be obvious, some will be maybe. Narrow it down rapidly with your what-if comparison. Then do a serious compare. "If I wrote this as a ... how complex would it be?" Complexity and fudging datasets to force them into that design pattern is a pretty good sign that this is not a good design. The one that flows the best for the needs of the system is your choice.
Refactoring later means you made a choice, but design considerations changed along the life of the project and now we need to push it toward another design. This happens too.

We have been using Plumtree G6.0 Portal integrated with ASP.NET 1.1
We have been using standard header/footer of plumtree and we used to refresh other portlets from these portlets.
We need to remove Plumtree and to handle the entire functionality in .NET only
We thought of using Frames, but it could not be possible because of its limitations, bookmarking,browser back button and the page scrolling.
In plumtree, scrolling will happen for the entire portal page, even if one of the portlet contents are more than the screen height.
But for Framse, it adds scrollbars to Frames and not to the page.
If we incorporate Header and Footer as user controls and embed them in all the pages, then on every post back, the entire page will be posted back. We we want to have it like header and footer and they refresh the intermediate portlet.
1. How portals are refreshing the contents of one portlet from another.
2. If we use AJAX, will it preserve updated viewstate? Whether ATLAS has got this functionality?
3. Any solution for this?
4. Suppose if we the existing Framework 1.1 what else would be the best way go to?

Do you know what problem you're trying to solve in duplicating the behaviour of the previous environment? i.e why do you need to duplicate the behaviour of Plumtree exactly?
...AJAX does not preserve viewstate (however, Telerik does have libraries that perform this function)
Are you boxing yourself into a design that prevents you from postbacks on the footer and header. What do these areas of the interface have where it would prevent you from doing postbacks on them?
There are many ways to use client-side scripting in tandem with server-side events to control the viewport of the users browser, so it is difficult to answer 'what is the best way' to go'.

I am creating a single instance class that is contained in a library that is only accessible to a non-singleton class in the library. Will multiple instances of the non-singleton still use the same singleton class instance? I am creating a user control for .NET and if more than one application uses the control at the same time from the same .dll then there may be serious problems if I don't figure this out soon.
