Hey guys, this question is out of curiosity.

What is the difference between querying, inserting, updating or deleting data in your database from the codeBehind than from a WebService?

I've been taught to do data access in the WebService and thats what i do, but the only reason as to why i can come up with is if you have a routine like NotifyWebMaster(Message); you dont have to replicate that code in every .cs file you want to access it from.

Are there any other reasons?

hi Harvey

I assume if you say Code behind, you are talking about behind a form(Windows) aspx(Web). cool Good Question. Its not a Good idea or a good Practice to write your database work in your Forms or Pages code behind. Especially me, i don't do my database work using wizards. i create a DAL(Data Access layer) and a BLL(Business Logic Layer). Now all your pages or forms as you said will call one function that you have a function repeated in all the pages as you said. If you taught to write your data access layer in your Web Service, its good and its a good Practice. but i Prefer DLL's Smile | :)

than web services. but it all depends on your and the Application you are writing.

Thanks

Hi Vuyiswa,
Good Answer. It always better to developed own BLL and DAL for Business and Database Access respectively, and its a very good practice.

Exactly. When you will choose web service or when to use dll that totally based on your requirement.

Nothing much. Webservice is isolated and you can change it without recompiling your application.

It depends on your requirement. I don't recommend using webservice for all your data access. You get better performance if your application is accessing the DB directly than from a web service. You need a webservice only when multiple subcribers are using it or you want to expose some APIs to the outside.

which code is not working ... Javascript alert or Response.Redirect.

I think if you redirect, why do you need to attach client attribute ?? Confused | :confused:

Sounds to me like you're binding to data in page load instead of prerender, so you bind to data before it's updated.

Oh didn't you notice, analogous to square roots, they recently introduced rectangular, circular, and diamond roots to determine the size of the corresponding shapes when given the area. Luc Pattyn[^]

You probably need to create a font using the info in the FontInfo object (name, etc )

Then why you are not using Java script Confirm

<script type="text/javascript">
var repl = confirm ("You want to save?")
if (repl )
alert ("save.....")
else
alert ("no...")
</script>

There are something like three billion (OK - I exaggerate) methods of popping up - just google for, say, javascript popup alternative for 200,000 hits. surely you'll find something.
