That suggests you're using a commercial component, and you've only purchased a license to use it until June next year.

If you want to extend that date, then you will need to purchase a new license.

What does that mean, where are you trying to write it - to a file, printer, screen, website ... ?

first of all thank you very much sir for your response.
sir i want to design a web page where from anyone can ask any question of any subject for eg maths.
suppose someone want to ask about solution for (a+b)2 [a plus b whole square] then how he/she can type 2 as superscript, and other symbols like integration, differentiation etc.

Richard MacCutchan9-Jul-17 20:46

You cannot type those symbols on a standard keyboard, without using multiple keystrokes, which are difficult to remember. You should use the standard operator symbols as defined in most modern programming languages, e.g. 7.2.1 Operator precedence and associativity (C#)[^]. For subscript and superscript on web pages see HTML sub tag[^].

If you want someone to help you resolve an error, then first you need to tell us what the error is. Just saying "it's not responding" and "something is going wrong" is not enough information for anyone to help you.

The only obvious problem is that you're using AttachDBFilename, but you don't appear to be connecting to an instance of SQL Server Express. That option only works with Express, and is a bad idea anyway:

Seems fairy self-explanatory to me. You're trying to attach a database with the same name as an existing database. You need to choose a different name, or stop using attached databases and create a real database instead.

How do I build an XML based News page in ASP.NET MVC? I would like to enumerate XML files inside a folder and build a list of summaries on the page. Once the visitor clicks on one of the summaries, I would like to load the associated XML file and render the full news content (with nice formatting included).

An example of the summaries page can be found [1] while and example of the single XML news page rendered can be found here [2]?
Should I write everything from scratch or there is a good tutorial to start with somewhere?

Thanks.
