Please don't cross post. It's considered rude and won't help you get an answer any faster. The original post is here[^].

Dear group,
I have to load all the dependent libraries of an ELF output file while it is loading.
SO for this i decided to write ELF parser to load the dependent libraries.
Please suggest me with a sample.
Thanks in advance,

I'm looking at implementing document storage and versioning for our ASP.NET application, and I would appreciate some input on various methods used, designs etc. Google seems to just yield adverts for document archiving systems, but I would like to investigate implementing our own as well.

Brady - effectively there are two mechanisms for achieving this. The first is to store the file in a database and use triggers to help you achieve versioning. The second is to store the file on a disk, and then store the path to the file (probably in a database). If you choose to store the path, you need to rename the file to something unique (e.g. a GUID), and map this back to the original filename in the database - fortunately this is incredibly easy to do. I'm unsure as to what you ultimately need to know, so if you want to refine your question or ask for more information, let me know.

Thanks Pete. We already use the stored path approach, but I've just met with my team lead, and the requirement wasn't described very well. All I need to do is move older documents 'off-site', i.e. remove them from the operational folder, on demand. The versioning actually refers to database based documents such as cost estimates, invoices etc.

Isn't that always the case. Not only do the lunatics end up running the asylum, they get to decide who gets committed there as well.

I'm quite lucky. Nearly all issues are logged internally, and only require a ten minute, in office, chat to sort out. At least we don't work off specs for this, the paperwork would be enormous.

Hey
This may not be the correct forum for this question but it is the closest I could find.
I have a considerable amount of class diagrams (rough sketches on paper) that I would like
to enter into MS Visio 2003. This is fine as long as I am dealing with types such as
C# int, C# bool etc. However I would like to be able to represent .NET and XNA types.
I have read that this is possible (to add in extra libraries) but am unsure how?
Can any one explain how to do this?
Thanks

Hi Everyone,
I would like to know under which scenario, in a web application we can use Web service to make database call. Means, what is the benefit of using web service to return data from database and to use that data in application. In this case, web service to be built for internal purpose only and not a public web service.
Can any one please suggest me why web service can be used to make a database call instead of simple DAL? What this extra layer of web service can give benefit to the architecture?
Thanks & Regards

Its a layer of abstraction, which gives the usual things - benefits of being able to replace the database+webservice end and have your application still working fine, easier implementation of security, and the usual downsides of more complexity, maintenance and worse performance.
Of course if you never intend to change the architecture, then you are just burning money to add complexity for no real reason.

Hi,
Principally that of abstraction. The chances are that whatever it is that calls your webservice should not know about the database at the other end- ideally if there is even one. It should think in terms of calling something to get the data it needs.
The webservice will form part of your middle tier, so should you change databases or decide to implement some caching etc, the client remain unaffected.
Of course, if you want your application to work other the internet as well, then you need to do something like this or you'll have to open up firewalls to the database port which exposes a nightmare scenario of security risks.
Regards,
Rob Philpott.

Hi everyone,
I have a question with Visual Studio 2008 and SQL Server Reporting 2005. My client already has a Sql Server 2005 license
which has SQL Server Reporting. The development team is developing a website using Visual Studio 2008. When we launch SQL
Server Business Intelligence Studio to create a new SQL Server report, it opens Visual Studio 2005, not 2008? Why is that?
Does this mean we have to scrap developing the site with 2008 and use 2005? Is there a way to continue using 2008 and
associate Business Intelligence Studio with VS2008?
Thanks!
John

We have to create some integration web services and were thinking about best practices. Should we favor flattening out the object model or be verbose (leave less room for interpretation/error)?
Example 1. Complex Types – The employeeListItem would be used to provide summary information about the employees. The salaryEmployee and hourlyEmployee would be used to provide details.
<employeeListItem>
<employeeId/>
<firstname/>
<lastname/>
<type/> (‘Salary’ or ‘Hourly’)
</employeeListItem >
<salaryEmployee>
<employeeId/>
<firstname/>
<lastname/>
<dateOfHire/>
<officeId/>
<salary/>
</salaryEmployee >
<hourlyEmployee>
<employeeId/>
<firstname/>
<lastname/>
<dateOfHire/>
<officeId/>
<hourlyrate/>
<hoursPerWeek/>
</ hourlyEmployee >
Example 2. Flatten objects – Just one type here all the details are provided in one object. When an employee is of type ‘Salary’ the ‘hourlyRate’ and ‘hoursPerWeek’ will be unused.
<employee>
<employeeId/>
<firstname/>
<lastname/>
<officeId/>
<type/>(‘Salary’ or ‘Hourly’)
<salary/>
<hourlyRate/>
<hoursPerWeek/>
</ employee >
Of course our objects are not as simple as this example but this general idea. So what would you guys favor 1 type or 3 types in this scenario?

There's a lot more to this question than this. Is this object going to be used on its own, or is it going to be in a collection? Instinctively I'd go with a normalised version of the object, but it really does depend on a lot of other factors. In the end, you're going to have to do a bit of profiling and work out what the size of the object you are going to be passing over the wire is, and if it's acceptable to you.
Unfortunately, there's no magic bullet that we can apply here. This one's up to you.

Hi everyone,
I am a software developer that is looking to improve the way I design my classes...
In my classes usually I have a constructor where an ID or some identifier is passed in, the constructor then goes off to the database and populates that objects member variables.
A 'save' of an object would find the relevant record in the database and overwrite it's data.
What's all this I've been hearing about a separate data access layer - how would you go about implementing one.
I have been thinking for a while that this is a bad design (should you get the data before
you create the instance of the class and pass this to the constructor?)
and if this is the case, wouldn't you just be moving the SQL into the UI or the calling method...
Does my way of doing this look as messy as I feel like it does; and is there any way around having to code each and every member variable into the class, and corresponding GET/SET methods? It feels like each class I design takes at least an hour each to hand code all the even generic getters and setters never mind the logic of the actual class itself and then is full of messy SQL Select and Update statements.
I guess I'm after a pointer to an 'architecture 101' type tutorial 
Thanks in advance for any pointers/ideas.

Thanks for your reply, however I usually do Google, and have only come to a forum on this one occasion to engage in a discussion rather than look at dry documents.

Dry documents published by well established leaders in the industry are far more valuable than, never mind.
Well that just proves you have no experience on c2.com since there are some extensive discussions on that wiki. Ok, I know return you to your regularly scheduled program of burying your head in the sand.

First of all, thank you for your link. It has been bookmarked and I am going to give it a read.
I'm sure you have your uses here but being personable is obviously not a strong point of yours ledmike. If you are trying to be helpful or teach someone then being a condescending troll is not the best way of going about it. However, if your intention IS to be a troll, then well done friend.
If you had considered this topic to be 'beneath you' then nobody was forcing you to post your stereotypical RTFM comment.
Is the rest of this forum so unfriendly to people that are just trying to learn?
I won't be sticking around to find out.

For better or worse that is simply Mike's personality (at least here on CP) so take it with a grain of salt. He actually seems to be in pretty rare form today.

there is nothing in my first reply that is not personable. You chose to respond to my help by calling the links I provided "dry documents" when clearly you could benefit from reading them. There are many people that come to code project that truly desire to improve their skills and welcome any assistance. I have no patience for the others.
You can lead a horse to water but you can't make him fish. Good luck.

Yeah, "There is also this thing called Google that will find information for you."
Real personable.

The whole point of a DAL is to abstract the "messy" part of retrieving data away from the UI which should neither care nor know how the data was retrieved or stored in the first place. That's not the job of the UI. The DAL is the place to manage the whole CRUD operations.
A common technique for data access is to provide a static Fill method that returns you an instantiated version of your model. This method could (for instance) use a DataRow to populate it's own information, so you'd have a controller class which retrieved a set of data (in the form of a DataReader) and then populate a collection of your model simply by "Filling" each item in the collection. BTW - there are some excellent code generators that automate the tedious process of getting the data out of the database and into your model.
