<%@ Page Language... question

[Ben Ong]

Hi I'm a new .NET developer and I was wondering if someone could
explain to me what exactly does each of these things do.

the "<%@ %>" -- does this define a namespace?

Codebehind="WebForm1.aspx.cs"
AutoEventWireup="false"
Inherits="HelloWorld.WebForm1"

and if i take those out and define the Page_Load function in the .aspx
file what the differences, if any, would be if i left the above listed
attributes in and defined the Page_Load function in the .aspx.cs file.
Thanks,

Ben

If you put your code in the .ASPX file and not in code-behind, your site
will be compiled at runtime.
If you put your code in the code-behind file, then the site must be compiled
before it will work.

The attributes indicate the code behind file. In your case, you created a
class "Hello.World.WebForm1" in the code behind file. If you notice, your
ASPX page inherits from that. The page's class is something like
"Hello.World.WebForm1_ASPX" and this is the class the gets executed on the
server when the page is hit.

If you do not have a codebehind file, and leave the directives on the ASPX
page, when you load the page, it won't be able to find the code-behind file.
(Parser error I believe)

I also suggest using code-behind, because you catch the common errors that
way: syntax errors, type mismatches, etc. If you don't compile your code,
you are left with the front end compiling the code when the page is
requested as well, which could slow down performance. Also, using code
behind makes it easier to seperate the code from the display of the page.

Thank you sir. I appreciate your help. That just made understanding
how to code in visual studio and .net a little bit easier.
