Please can you post a link to the code? Your local file can't be accessed from here.

It's example take from September meeting in Sydney. I use alethzero for test. Balance works and show my Ether balance, but eth.storageAt for my contract don't work in alethzero. When I use json on terminal

 ( 
curl -X POST --data '{"jsonrpc": "2.0","method": "storageAt","params": {"a":"0xad2b15ffbd3204a69745e0d7c5b017bb2cb4015f", "x":"0x60bcc52db8acbb1bab463253cb3a2abf24950c28"},"id": 1}' http://localhost:8080
{"id":1,"jsonrpc":"2.0","result":"0x7d00"}
)

everything is correct.


<html>
<head>
<script type="text/javascript">
function init() {
var clientAddr = eth.coinbase;
document.querySelector("#clientAddr").innerHTML = clientAddr;

var contractAddr = "0xad2b15ffbd3204a69745e0d7c5b017bb2cb4015f";
var alethEtherBalance = eth.balanceAt(clientAddr).dec();
document.querySelector("#alethEtherBalance").innerHTML = (alethEtherBalance / Math.pow(10, 18)) + " eth";
var alexosBalance = eth.storageAt(contractAddr, clientAddr);
document.querySelector("#alexosBalance").innerHTML = alexosBalance.dec() + " Alexos";

document.querySelector('#sendCoins').onclick =
function() {
var destAddr = ("0x" + document.querySelector("#receiver").value).pad(32);
var amount = document.querySelector("#amount").value.pad(32);
var data = (destAddr + amount).unbin();
document.querySelector("#data").innerHTML = data;

var res = eth.doTransact(eth.key, 0, contractAddr, data, "100", "10000000000001");
};


}

window.onload = init;

Here is a link for example which I tried http://cryptorevolution.blogspot.com.au/2014/09/notes-on-sydney-ethereum-meetup-1.html

@Bezpol‌ please use the 'code' html tag to wrap your code neatly. I've updated your post to demonstrate the tag.

robmyers · September 2014

Bezpol. Thank you for your code (and Stephan thank you for reformatting it. :-) ).

Try using eth.stateAt rather than eth.storageAt in your Javascript, e.g. eth.stateAt(contract, 1001, "");

Bezpol · September 2014

Thanks.

Bezpol · September 2014

It's ok after change eth.storageAt to eth.stateAt ... thanks

@Bezpol‌ @robmyers‌ what about doing the transfer in the d-app? is there a workaround for that?
Also does this mean, AlethZero doesn't support serpent anymore?

StephanTual · September 2014

AZ supports serpent to this date.

heliumcraft · September 2014

@Stephan_Tual‌ so the examples at https://github.com/ethereum/serpent/blob/master/examples/subcurrency.se work for you? Aleth Zero reports an error (like it's only expecting LLL) and the contract doesn't go into the blockchain. with LLL it works fine.

StephanTual · September 2014

@heliumcraft‌, the example at https://github.com/ethereum/serpent/blob/master/examples/subcurrency.se works just fine, yup.

Are you using the latest devel version? I'm running 0.6.8 build 32-1.

Bezpol · September 2014

Me too ( but I don't have ether on my accounts and Develope 0.6.8 cpp-ethereum build 64 ! ). After put code from example to Data Windows I was
Error (file "main", line 1, char 0): Expected indented child block!
Error (file "main", line 1, char 0): Expected indented child block!
Error (file "main", line 1, char 0): Expected indented child block!
Error (file "main", line 1, char 0): Expected indented child block!

@Bezpol: Python is indend-sensitive. Please make sure you have all the indent exactly as they appear in the file, depending on your OS the copy paste likely corrupted that.

what about doing the transfer in the d-app? is there a workaround for that?

Bezpol · September 2014

How do recieve ether for testing ? After change for develop version cpp-ethereum and connect aggain to testnet my account are clear ....

Bezpol · September 2014

Ok. I found how do it. By irc.

StephanTual · September 2014

@Bezpol‌ or use the faucet: https://zerogox.com/ethereum/wei_faucet

Bezpol · September 2014

Thanks.

Howdy, Stranger!
