Hi all,
I use Application object in ASP.NET.
I set it’s value in one page and read it in another page but I don’t know when I can dispose this object in order to in the first page it’s not set and if an event accord it set again.
Thanks in advance

You should only use the application object for things you want to keep across user sessions. Like some sort of static data that all users would be looking at. It sounds like you should be using a session variable to pass things from one page to the next. Session is very similar to the application object except it is only for that user, other users can see that object, they can only see their own session object.
Either way if you want to remove and object from the session or application you can just set it to null or Nothing in vb.net. There is also a Remove method in the object to remove something from the application or session object.
Hope that helps.

When i can use it?(What event)
|
|
|
|
|
You can use the session and application object anywhere in the codebehind. All events have access to it.

I use it in Finalize Method of the page but in order to access again to it i don't know What i can?
|
|

Perhaps it is better for you to explain what you are trying to do and then I might be able to suggest something for you to try. Finalize method of the page seems like a strange place to set a variable in session or application. Most of the time I set it in th page load event.

You have to grant WRITE permission for asp.net account, I think

manage your asp.net account permissions
or config your web.config file

create new folder in your hard drive. c:\temp for example.
select it and right click over the folder and chose properties.
select the security tab and then press add button to adding new user.
select aspnet user and press ok.
in the permissions section allow fullcontrol access.
then your operations(delete,modify,create,...) must be referenced to this folder.

I'm not sure...but here is just a suggestion
Open IIS MMC, check the ASP.NET version setting of your site
<< >>
|
|
|
|
|
goto windows\microsoft.net\framework directory and find .net Frameworke version that your application use it and from it's location find aspnet_regiis.exe and execute it such as "aspnet_regiis.exe /i"

Hello,
take a look at the following line of code...
<%@ Page language="c#" Codebehind="Default.aspx.cs" AutoEventWireup="false" Inherits="_Default" %>
however, if I put the class _Default in a namespace, say MyNamespace and try the following line:
<%@ Page language="c#" Codebehind="Default.aspx.cs" AutoEventWireup="false" Inherits="MyNamespace._Default" %>
VS generates an error:
Could not load type 'MyNamespace._Default'
Any help would be highly appreciated...

remove the _ (underscore) from the
<br />
Inherits="MyNameSpace._Default"<br />
to
<br />
Inherits="MyNameSpace.Default"<br />
|
|
|
|
|
Thanks for the reply pal, have tried that already, doesn't matter what the name of the class is, it still won't compile...

Just to be sure, did you put codebehing class (in .cs file) into same namespace?
I don't feel like firing up IDE, but I think that pages are always in some namespace (default project namespace), and you don't prefix class name in Inherits page directive. Did you try it without MyNamespace, add it only in codebehind?

maybe u bind your listbox in pageload or prerender event.
in this state in first time bind your listbox and set that index to -1 automaticaly
make sure your list box bind once
or take it to:
if(!IsPostBack)
BindMyListBox();//this is your bind procedure
