both are used for State Management
ASP.NET session state enables you to store and retrieve values for a user as the user navigates the different ASP.NET pages that make up a Web application
as HTTP is a stateless protocol But the life span is upto that session only .
Application state is a data repository available to all classes in an ASP.NET application. Application state is stored in memory on the server and is faster than storing and retrieving information in a database. Unlike session state, which is specific to a single user session, application state applies to all users and all sessions. Therefore, application state is a useful place to store small amounts of often-used data that does not change from one user to another. The topics in this section provide information on how application state works and how to use it.

e.g As you logged in Code Project by any user name , Your activities are in one session but at the same time you can see total number of Users Logged in that is Application variable

I got The Solution .
you can use the method

FormView_Inserted(object sender, FormViewInsertedEventArgs e)<br />
{<br />
        if (e.Exception != null)<br />
        {<br />
            lbl_exception.Text = e.Exception..InnerException;<br />
            e.ExceptionHandled = true;<br />
            e.KeepInInsertMode = true;<br />
        }<br />
<br />
}<br />

Hi,

You can set default font style of a page in the Body tag.

<body style="font-family:verdana;font-size:10pt">

I hope this will help you.

What things are recommended to be kept in App_Code Folder? Is it be must for som things? Confused | :confused:

Re: App_Code

Sathesh Sakthivel24-Apr-07 19:32

You can store source code in the App_Code folder, and it will be automatically compiled at run time. The resulting assembly is accessible to any other code in the Web application. The App_Code folder therefore works much like the Bin folder, except that you can store source code in it instead of compiled code. The App_Code folder and its special status in an ASP.NET Web application makes it possible to create custom classes and other source-code-only files and use them in your Web application without having to compile them independently.

The App_Code folder can contain source code files written as traditional class files — that is, files with a .vb extension, .cs extension, and so on. However, it can also include files that are not explicitly in a specific programming language. Examples include .wsdl (Web service description language) files and XML schema (.xsd) files. ASP.NET can compile these files into assemblies.

The App_Code folder can contain as many files and subfolders as you need. You can organize your source code in any way that you find convenient, and ASP.NET will still compile all of the code into a single assembly that is accessible to other code anywhere in the Web application.

Satips.

How to protect the Database

24-Apr-07 19:38

Contains source code for utility classes and business objects (for example, .cs, .vb, and .jsl files) that you want to compile as part of your application. In a dynamically compiled application, ASP.NET compiles the code in the App_Code folder on the initial request to your application. Items in this folder are then recompiled when any changes are detected.

If you ASP.NET application can access database, Using the same login information you can access the backend database also. My suggestion could be keep your login informations secure .

Session variables are for perticular seesion i.e life span is only for that session afer user logs out or session ends this varaibles no longer exist .
Application variables are for the application level they exist beyond n numbers of seesion untill application is running .
Take an example
IF i want to know number of users using my website at same time i will use Application variable for that.
Where as if i want to know time span for which user was on line i will use session variable

asp sendmail script

I have been trying to send an email from a form using a sendmail script that I found on this site by Nathan Ridley. I have implemeted it and am having trouble getting it to send the email. There is a test mode for the script that works fine. I am sending it using the HTML template and when it is in test mode it comes up in the browser no problem. When I set test mode to no, I submit the form and get the confirmation page but no email is sent. I have tried multiple emails and also tried to add a few lines a code I have seen on other send mail scripts, but when I change the code I get errors. I get no errors with the script Nathan wrote, there is just no email sent. I am wondering if anyone has any recomendations for me.

or what error it shows while you send the mail?

I din't think about antivirus blocking it. I will look into that. i don't get any error when I hit the submit button. I am taken to the confirmation page by the redirect just like it is supposed to, but no email is sent. I am wondering if it is a server setting that I over looked.
