ASP.NET

2-Mar-07 3:26

Hi,
I'm new to ASP/Javascript so this may be a farily straight-forward question. I have an ASP2.0 website that uses calls javascript functions. When I create the javascript functions in the asp page, there's no problems whatsoever.

However, I also created a class called MyServer in a seperate js file which has been added to the project. I can never call the class or public methods from inside the aspx page though. For example:
<script> type="text/javascript">
var ServerCheck : MyServer = new MyServer();
ServerCheck.MethodOne();
..
</script>
returns an error. I know the javascript class is okay, because it works when compiled (jsc in VS) and run as an exe!

What you described doesn't make a whole lot of sense but sounds like you haven't added the external script file to the page. Try this

<script type="text/javascript" src="path/to/js/file.js"></script>

stick that in the head element before your script above.

What error message do you get?

That the code works when compiled as JScript.NET does in no way imply that it can be used as Javascript. On the contrary, I think that it's nearly impossible to write any useful code that would work both as JScript.NET and Javascript.

So the javascript code looks something like:

public class MyServer extends System.Net.NetworkInformation.Ping<br />
{<br />
    var testServer = "Foo";<br />
    var timeOut = 5000;<br />
    var pingReply : System.Net.NetworkInformation.PingReply<br />
    <br />
    public function RunServerCheck() : String<br />
    {<br />
           try<br />
           {<br />
               pingReply = this.Send(testServer, timeOut);<br />
               return pingReply.Status;<br />
           }<br />
           catch(PingException)<br />
           {<br />
               return "Could not contact server!";<br />
           }<br />
    }       <br />
}<br />
public var ServerChecker : MyServer = new MyServer;

The 'var ServerChecker : MyServer = new MyServer;' initilisation
does not seem to be legal in ASP.Net.

That is not Javascript at all. That is JScript.NET.

You can't use JScript.NET-code as Javascript, just as you can't use C#-code as Javascript, or use this weeks tv guide as Javascript.

Although Javscript and JScript.NET has some similarities, there are some crucial differences:

Javascript does not support inheritance.
Javascript can not use .NET framework classes.
Javascript does not have data types.
Javascript does not have access modifiers.

There are a lot more differences, but those are the ones that makes it impossible to use your JScript.NET-code as Javascript.

Yes, but I was hoping such JScript code could be invoked in an ASP page
as javascript is.

It can, but only if you use it as server code and call it from the server. You can't use it as client code, and you can't call server code directly from the client.

There is no direct equivalent but you probably want the FileUpload control (seems pretty logical to me, maybe you could of checked first).

TAX RATES

I am developing a web site with ASP.NET and C# and I need to know what tax rates should be added to the price of a product so I could implement the application accordingly.

Could someone tell me if the tax rate added to the price of a product sold in a online e-commerce web site is the one existing in 1) the country of the person who bought the product, 2) the country where the web owner site resides, 3) the country where the server hosting the web site resides or 4) the country where the owner registered his company ( supposing he did so ) ?

And what would be the situation if the e-commerce web site owner works just as self-employed and did not register the web site as company ?

That depends from what country you're selling from.

In the uk, its a combination of where the company's registered (i.e. where the invoice is coming from)and where the shipment is going (and where the invoice is going).

If from UK -> UK then we add VAT (tax)
If from UK -> Eu (europe) non tax registered customer then we add UK VAT
If from UK -> Eu to tax registered customer then we don't add VAT *
If from UK -> Rest of world then we don't add VAT (although the recipient is responsible for any import duty)

*this is subject to a threshold for each EU country. once we reach that threshold, we need to register for VAT in that country and charge VAT at that country's rate for all sales to that country.

I see you are in the US, so most of the above won't apply, but it's most likely to be 4 on your list, and I think that you also need to take into account state sales tax if you are in a state that adds extra sales tax. Generally, exports aren't charged sales tax, as the recipient will usually have to pay duty on the import.

It won't be from the country the server is physically located in - eg, you could have it hosted on the space shuttle, sealand, or mars if you can get the bandwidth.

Hope that points you in some kind of direction.
