The flow of try catch block is when your code in try block occurs an error, it will do something in catch block. After that it will do something after catch block. So that:

SqlConnection connection = new SqlConnection( "ConnectionString" );
SqlCommand cmd = new SqlCommand( "CommandText", connection );
try {
    connection.Open();
    cmd.ExecuteNoneQuery();
}
catch {
    // do something
}

now you put each line in try block in try catch block like that:

try {
    
    try {
        connection.Open();
    } catch {
        // do something
    }

    try {
         cmd.ExecuteNoneQuery();
    } catch {
        // do something
    }

}
catch {
    // do something
}

Do you understand now?

Can I use static variable in a page?

I m building an application in which I redirect the user to a particular page. In the Page Load event of the that page , I assign a variable some value. Then I call the Button click event on that page. I have applied the !IsPostBack so that the Page Load event does not occur on clicking the button. Now the problem is that I want to use the value of that variable which i was population on Page Load event.
Can I use that variable as static?
I have a doubt in my mind that as I am simply redirecting the users to that page, the value of that variable could be set to some another value if another user is redirected to that page as the variable is static. Please help me to clarify my concept.

Thanks,
Sandy

The problem is that all visitors share the same static variable...

Can I store that variable in View state to remove this problem? because I don't
want to share the variable between different users.

Thanks,

If the uploading (ContentLength) exceeds 4 MB, IIS/ASP.NET will break the connection. This setting is in machine.config.

(*) Enable Script Debugging from Internet Explorer (Tools -> Internet Options -> Advanced)

(*) When the browser breaks with 'Pick a debugger', point it to the Visual Studio in the selection dialog box.

There are two things that you might need to do:
+ Create an event handler for the Click[^] event of the button.
+ In the handler, you can use the Dictionary[^] class to create a new folder on the server, also you should remember that your application should have permission to create folder, otheriwise you will get the error.
