Where can I get real time exchange rates? [resolved]

[Patch21]

Hey there

I'm building a web app that needs a currency converter, and at the moment all I can think of is getting hold of real time exchange rates and then doing the math from there. Is this the best way of doing it? I will be storing only one currency in the database. How can I get hold of these exchange rates? I've heard theres a web service out there that supplies them, but i'm not sure where that is.

Any help will be much appreciated!

Thanks

I searched on google for this so no idea what its like but im guessing its the sort of thing you are after

cool thanks

I found that web service I mentioned. You can give it two countries and it returns the up-to-date exchange rate. Quite neat.

Here it is if anyone is curious:

No worries. I may actually need this for my site.

As I haven't used web-services before/yet - do you think you could post a code example please?

All you gotta do is add the web reference to your solution (Project --> Add Web Reference...). Search for the web service and select add reference.

The function I'm using at the moment is this:

Public Function getERate(ByVal country1 As String, ByVal country2 As String) As Single

        Dim CEService As net.xmethods.www.CurrencyExchangeService
        Dim sngCurr As Single

        If (Not country1 = String.Empty) And (Not country2 = String.Empty) Then

            'instantiate web service
            CEService = New net.xmethods.www.CurrencyExchangeService

            Try

                'get the e-rate from web service
                sngCurr = CEService.getRate(country1, country2)

                Return sngCurr

            Catch ex As Exception
                Return Nothing
            End Try
        End If

        Return Nothing
    End Function

        Return Nothing
    End Function

net.xmethods.www.CurrencyExchangeService is a ref to a webservice.
Look at post #3, #4 and #5 in this thread.

You also may want to look up how to use webservices oin the web.

I already follow but got that error. the Web ref name should be what? I keep changing and it now give me this Type expected message.

When u setup a web service in your app you assign it a "Web Reference Name", this is what u use to asses the web service, ie if I called it Woof then I would do:

Dim MyWebService As new Woof

Thanks Woka. finally it works its because last time I download the web reference and save it into my root and I got mess up, this time I just add web reference directly from the URL and I see the default web reference name so I understand what you mean already.

Anyway, now no error but I just need a simple currency converter that just convert a few country to country, what should I do now to setup a basic currency converter with that code loaded?
