@abidarahma increase the gas while submitting the contract. what are you using to submit the contract. & where r u deploying it ?
@build121 they got lot more development to deal to. I guess you must talk to someone who is well verse in that. may be upload a job on upwork might do the trick.

@tkdp you might be trying to pass certain ethers to the contract and not implemented the "payable" function. it happens with solidity version ^0.4.0 .please check that. It's not a bug @prashanth-devadas

@tkdp these deployed contract shall not do anything until u call them from outside using web3/RPC mechanism.

Hello, i'm new to ethereum; i followed the tutorial for the MyAdvancedToken stuff on https://www.ethereum.org/token ; i do not understand why i'm not able to do the sell or buy-contract methods after deployment; neither on my local "testrpc" nor at the ethereum testnet; what are the requirements to use these functions?

Hi, I am trying to deploy The Shareholder Association contract but I receive an error:
Undeclared identifier.
ProposalTallied(proposalNumber, result, quorum, p.proposalPassed);
for 'result'
I already created my own token and it worked without any problem
Does everyone get this problem ?
and i am using Mist on the test network

@insipx
so how do you deploy contracts on the network?

@InsidiousMind the only way I know is to send a transaction from geth.
@Stigjf which tutorial are you following?

@ashbringerf
Hi every one, may I know can I build a transaction inside of a contract?
Alex
@mintheredonethat
@ashbringerf From my understanding, contracts can only send messages (not transactions) to other contracts, as transactions need to be signed by an externally owned account. Someone please feel free to confirm/correct me.

@jeffanthony
Ethereum cannot tell the difference between a human and a contract account. I'm not sure about 'building' a transaction inside a contract but afaik it can send a transaction if it has been programmed to do so.
Yoichi Hirai
@pirapira
@jeffanthony EXTCODESIZE instruction can tell if an address has some code or no code.
Stigjf
@Stigjf
@pirapira I tried to paste the code of the Shareholder Association: https://ethereum.org/dao#the-shareholder-association
@pirapira and i received the error : Undeclared identifier. ProposalTallied(proposalNumber, result, quorum, p.proposalPassed); and 'result' is underlined
@pirapira I already tried the codes of Token and Blockchain Congress and it worked without any issues
Yoichi Hirai
@pirapira
I get the same error.
Replace result with 0 and the code compiles...
but the tutorial is broken there.
@Stigjf will you document the compilation error here? https://github.com/ethereum/ethereum-org/issues/new

If I am creating a name registry contract (register, deregister name/address pair) and have the following mappings:

mapping (bytes32 => address) public addresses;
mapping (address => bytes32) public names;

How would I go about iterating over these mappings? My goal is to have a front-end that simply displays a table of names & associated addresses.

@ashbringerf
@mintheredonethat Thank, I think you are right.

Hi all. When a new change is done on a solidity-browser code, how can I make it work for existing contracts? Currently, when I change the code, only new contracts are impacted.
