I did have a look at the source of their pages to see if it was not to difficult to parse out the rates. How did they know what I was about to .. ? This I found: <WARNING> <!-- // *** LEGAL WARNING! *** // // IF YOU ARE READING THIS, YOU MAY BE CONSIDERING EXTRACTING RATE DATA FROM XE.COM. // THIS IS A VIOLATION OF THE LEGAL TERMS OF USE.

Do you want to redistribute the rates (or making them public) or do you want to use them yourself? I don't see a difference from reading a website and then typeing the figures in from parsing the HTML. As long as it is for own use.

I don't see a difference from reading a website and then typeing the figures in from parsing the HTML. As long as it is for own use. Forget what I wrote. You are not allowed to use the rates in whatever form without written permission. You are not even allowed to use the rates to create an invoice. I don't know how difficult it is to get written permission but the site looks rather superfluous to me.

Yes, I had discovered that myself. But is there another site somewhere or a service on the internet that delivers rates ? Thanks. Hans.

Then the rate could be parsed out from one of the <td></td>'s from the diagram. That's not to difficult. Thanks. At the bottom of the page one can read: "Copyright © 2004 Yahoo! Inc.

It does not contain the word 'parse'.<g> So do you think I am allowed to use a rate programmatically grabbed from that page to use it for a site that displays euro values and converted usd values ? And I'm still in for server that just would return the rate alone. Hans.

I have not dug into it but was thinking that you could read the page and learn how to query the exchange rates the same way that page does instead of parsing the page itself. Side note: I have no clue as to what a TldHTTP is. Is that an Indy class? (You're talking with a dummy Win32 coder here.)

I did not read the page source so did not see that note. I think it does apply to you but that they most object to the use of their info without attribution.

No, the link you provided is the same as when you manually fill in the inputbox and choose the selects and then click the 'Convert' submitbutton. Only a "&c=0" is added to the query. I could not find out what different values for c did. The result is a page that is the same as the original link. Quote: Side note: I have no clue as to what a TldHTTP is. Is that an Indy class? Yes.

They charge a flat annual fee of US$540 The currency converter on http://www.xe.com nicely illustrates a security problem. They use method=POST to send data to ther cgi, but it accepts GET as well. I.E. To see how much US$540 would be in euros, click here: http://www.xe.com/ucc/convert.cgi?Amount=540&From=USD&To=EUR Strong Euro! Think that we will look for something cheaper. Hans.

After looking at: http://www.exchangerate.com/world_rates.html?cont=Europe I doubt if I can trust them. The page tells that it is "Last Updated: Fri, 02-06-2004 14:51 (+5 GMT)" but it shows for the Netherlands the Guilder and for Germany the Mark. Both countries use Euro longer than a year now. Thanks.
