BTConvert

[Tritonio]

I don't think one existed so here it is!

BTConvert. A portable currency converter for BTC, USD, EUR, GBP, AUD, Linden$, Pecunix, RUB, CAD and PLN. It takes the exchange rates from the internet every 30 minutes. Nothing fancy, it just works. I think...

AutoIt3 sources are included. If you don't need them just keep the executable.

Suggestions, tips etc are welcome as always.  

Also if anybody has missed it I've made a portable wrapper for Bitcoin: http://bitcointalk.org/index.php?topic=944.0

Changes so far:
v1 Initial version.
v2 Added AUD.
   Added refresh button.
v3 Some timers changed.
   Added link to bitcoin.org when someone clicks on his label.
v4 Users that click refresh too often are asked if they are sure.
   Added Linden dollar and Pecunix.
   All labels are links to related pages.
v5 Changed Lindel dollar source.
   Fixed a bug with manual refresh warning.
   Limited the decimal digits to something sensible.
v6 Added RUB and CAD.
   Fixed the LD label link.
   No more beeps. Instead it will show a persistent message that something went wrong.
v7 Andrzej added PLN. Thanks for that Andrzej. :-)
   Stores the last update time in the INI so that exiting and running the program soon won't cause an update.
v8 Docks in tray.
   No longer asks if you refresh the rates very often.
v9 Support for the new Mt Gox ticker data.
v10 Fixed last version because it broke.
   Data for most currencies is taken from: http://openexchangerates.org/latest.json
   Changed BTC decimals to 4. (0.0001

I've added some more currencies: Pecunix and Linden dollars.

[BitLex]

nice work,
would be cool if you could change the L$ source from LindeX to VirWox,
cuz that's what all BitLex calculations are based on.

[Drifter]

Isn't working for me unfortunately. At first there is a loud beeping every couple seconds while saying "Failed to update USD/EUR". When I finally enter data (1000 BTC), it gives me this:

[Tritonio]

Drifter that would happen if you couldn't connect to Google or if Google was sending back unrecognized data. I looks like the only rates that weren't updated was the ones that Google is queried for. Are you using any proxies with Internet Explorer?

BitLex you mean I should change where the converter get's it's data or just just change the source in the about dialog? I suppose you meant the former. I will do it in the next version. :-)

[mpkomara]

can you reduce the precision of the exchange rate to only a few decimal places?  tip sent.

[Tritonio]

mpkomara I will do it today after I finish work. I will put something sensible for each currency. Thank you very much for the tip. :-)


EDIT: I made the two requested changes. Download it using the same download link. Here is the changelog so far:
v1 Initial version.
v2 Added AUD.
   Added refresh button.
v3 Some timers changed.
   Added link to bitcoin.org when someone clicks on his label.
v4 Users that click refresh too often are asked if they are sure.
   Added Linden dollar and Pecunix.
   All labels are links to related pages.
v5 Changed Lindel dollar source.
   Fixed a bug with manual refresh warning.
   Limited the decimal digits to something sensible.

I don't know if anyone else has noticed this but it often fails to update the BTC/$ rate. If you click refresh though it will update it normally.I guess it's Mt. Gox that delays to respond and some timeout expires. Anybody having this problem too?

[LZ]

I will be happy if it will also show RUB exchange rate.

thanks for switching to virwox-data, you missed the Func LDlabelClick() though, it still points to the LindeX Market, no big deal but might confuse people, cuz it shows different prices.

virwox got a json-api too, btw, you might want to check that instead of the main-website,
never used AutoIT myself, but this is what i do in php

Code:

#### VirWox - Data
$url = 'http://api.virwox.com/api/json.php';
$data = '{ "method": "getMarketDepth", "params": { "symbols": ["EUR\/SLL", "USD\/SLL"], "buyDepth": 1, "sellDepth": 1 }, "id":1 }';
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json')); 
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch, CURLOPT_POST, 1);
  curl_setopt($ch, CURLOPT_URL, $url);
  curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
  $output = curl_exec($ch);  
  $obj = json_decode($output);
  curl_close($ch); 
#echo $output."\n\r";

I will be happy if it will also show RUB exchange rate.

I will add it in the next version along with Canadian $. :-) But I will use Google for the $/RUB rate since ALL conversions in BTConvert go through US$.

OK Bitlex I'll use the json URL instead. It should be a little faster after all. Oh and I will change the label too... I thought I had.

I'll post the new version before Monday.

[Tritonio]

Version 6 is out.
*Added RUB and CAD.
*Fixed the LD label link.
*No more beeps. Instead it will show a persistent message that something went wrong.

I didn't change the JSON thing yet...   I was a bit bored.

Oh cool,you even have Aus dollars.
 

[Tritonio]

Glad you liked it. :-) BTW thanks to whoever sent some coins! 

[LZ]

Thanks for v6! I am happy now!

In a related thread I started a bounty to get a web based converter done.
