Well, at some point, you need to present a website to the world and make sure your server is secure, this is not the fault of ASP.NET. A webservice is just the same, it's on a server, and it needs to know your database passwords, etc. The intelligent thing to do is to not make your website have SA access, but only access to run procs, which then define the scope of what people can do with your db if hacked,.

In that case, a layer of abstraction may make a lot of sense, yes.

Thanks Christian,
If you think it makes senses to have an additional data access layer, then any advice or solutions to the two issues I mentioned in my original post?
regards,
George

1 - if it's a bottleneck depends on your site's traffic and your site's resources
2 - you CAN return a datatable from a webservice, but I'd lean towards passing strongly typed collections of entity objects.

Ok. So are you saying your database structure changes every month? You can reduce code changes if you design your database well. Don't access the tables directly on the code. Use views to abstract the internal table structure. Use procedures to abstract the data insertions/updations. In such case, a table structure change will not affect your code. You only need to change the procedures/views.

Dear All,
Are you aware of any face tagging library that is available for .Net? My idea is to have the facility to implement face tagging such as hi5 and facebook do.
I believe that a library which gives the co-ordinates of the faces in an image will be sufficient. What are your ideas in this regard?
Many thanks

If such a library exists for free, I'd be astounded. I'd not be surprised to find a commercial library, tho.

You add flash with HTML, it's an object tag, from memory. You don't need any control.

Dear All,
I have been using ASP.NET for quite a while now and this questions has been in my mind for quite a long.
So let us assume that I have two classes LogAction and LogEntry. The class LogAction describes an action that is found in a log such as "Login", "Deleted a record" etc. The class LogEntry implements the actual entry that will be put in the log. This class has a LogAction as one of its entries.
So far so good. Now let us move to the data access layer. Suppose that I have a DAL class for both LogAction and LogEntry. In the DAL of LogAction I implement an Add method which calls a stored procedure which enters a new record in the appropriate table and also other methods such as Get methods.
Now if I want to add a LogEntry in the database I have to check whether the LogAction (which is one of its member) is already in the database. If it is not, I need to insert it.
The question I have is how to implement this logic. I know that for efficiency's sake, the best way would be to implement a separate stored procedure which does all these checks and entries in one connection.
But for the sake of OOP it would be better if the DAL of LogEntry consults with the DAL of LogAction to see if the LogAction is already present etc...
Which in your opinion is the best way to implement such logic. I know that this is a fundumental issue in enterprise application design.
Many thanks for your help!
Chris

Well, I wouldn't write a DAL for each class, I'd just write one dll. Then I'd write my proc to be as efficient as it can be. I don't NEED to create a LogAction in my C# code, I just need a return from the DB that tells me if one existed in the DB or not.

I'm using vb.net application form
My form requests user to enter ID in text area to retreive some data for printing
I want to know is it possible to pass this ID as a paramter when I call the web application form without requesting user to submit it I mean that I will send user link of the application form with the ID as a parameter just as we do in a web form.
|
|
|
|
|
From what I understood, you have a windows application where user will enter some id. You need to send that id to your webapplication. Right?

I think this means you're in the wrong forum, b/c you're not asking about an ASP.NET app. In a windows form you pass parameters as properties or to a constructor.

IIS6.0 will not support extension-less URL rewriting. When you run from VS, all requests are processed by ASP.NET engine and extension-less URLs will work. In IIS, this is not the case. IIS7.0 allows you to do extension-less URL rewriting though.

You can use Filemon to see what the page is actually looking for:

You can filter the output for the particular worker process that your website is in. Good luck!

Hello,
VS2008-C#-linq
I'm trying to create a news system website. I have a table with 6 columns:
id-int | name -text | description -text | details - text | date - date | picture - image
I want it to look like this http://money.cnn.com/news/ - the first news on the site.
The picture in the right and in it's left: from up to bottom: name/date/description.
The description will be a hyperlink to a form where i will display the details.
I have managed to create an image object and fill it with the proper image. I don't know
how to do the rest: display everything in the order i want.
The code so far:
DataClasses1DataContext db = new DataClasses1DataContext();
var date = from c in db.test1s
select c;
foreach (test1 a in date)
{
Image Photo = new Image();
Photo.ImageUrl="Work.aspx?ID="+a.id;
}
where test1 is the table.
Can someone tell me how to do the rest?

That is too much for a forum post. You can use a repeater control to design the layout which you have specified. Repeater provides great control over the rendered HTML.

Hello,
does anybody of you know if there is the possibility (e. g. through third party plug ins) of enabling Visual Studio 2008 to use code snippets in .aspx files?
I know how to use them in vb.net files (and cs and xml) but VS doesn't seem to be able to do this in aspx files(ctrl-k,ctrl-c gives a negative response). All my searches have only led me to sites / tools (Snippet Designer etc) which covered only the other languages.
Is there a way? I haven't found one but maybe some member of this forum may know of a possibility?
Thanks in advance

As far as I know, I don't think you can use snippet in aspx file. Yeah but in VS 2010 IDE you will be able to use code snippets in aspx.
