@MidnightLightning Hello! How do I use Remix to compile Solidity code and use it in Ethereum Wallet? It seems that the compiler needs to be updated in order to compile the Shareholders Association code in the tutorials. And, I read a few threads back that I can use Remix to compile the contract instead. How will I do it? Thank you.

@jjpsuarez1113 you should create private ethereum net, and choose web 3 Provider environment

I'm on Rinkeby and Remix isn't detecting my account even if I connect it to the localhost. I'm using Ethereum Wallet 0.9.0.

In the right sidebar of the Remix interface, switch to "Settings" and set the compiler to whatever you want. Click the "Compile" button to make sure your contract is re-compiled with the new version. Switch to the "Contract" tab, and under the blue header for your contract, click the "Contract details (bytecode, interface, etc.)" link. That will expand out a bunch of raw data about the contract, including a "Web3 deploy" script, and the full Bytecode, which you could copy and paste into the Ethereum Wallet software as "transaction data" to send.

what is a pragma solidity and can i change it?

@Saoming The first line of a Solidity script often includes a "pragma" line that indicates which version of Solidity is needed to compile that code. If you have "undeclared identifier" errors, that likely means the compiler you're using is too old and doesn't know those new commands.

so in order to make [DApps] do i need to make it from meteor js ?

Meteor is not needed to make a DApp, thought it does make it a lot easier. You can just use the web3js infrastructure to add basic communication to the Ethereum network to your web application.

someAddress.call.gas(250000).value(msg.value)();In that case, who is paying for the 250000 gas? Is it the msg.sender or the contract?

@squlio-jmul The msg.sender is. That command limits the sub-transaction to 250,000 gas, which the sub-transaction might not use all up, so it might not need to all be paid for.

can someone link to the best way to purchase ethereum in USD... or the process of downloading a wallet etc...

@ReneRomoJr For someone just getting started, Coinbase is an easy way to get some ether for USD.

There are plenty of verified and registered charities, OTHER THAN Red Cross if you have a beef with them.
@christopherdro Charities are also supposed to obtain that type of status from the IRS.

Habitat for Humanity, a registered charity, a well known charity started by Jimmy Carter accepts Ether, https://eth4harvey.com/
If anyone wants to donate their Ether, Jimmy Carter's charity is pretty safe NOT to be slimy scammers.

@MidnightLightning One last question, how about the parameters that I have to set before deploying a contact? Isn't it that when we deploy using Solidity in the Ethereum Wallet software, we get the chance to input certain fields such as for instance in the Shareholders Association code, the beneficiary address, the number of quorums and the minutes for the debate. When trying to deploy using Bytecode in the Ethereum Wallet, I don't get the chance to view the parameters I have to set before deploying in the contract as compare to using the Solidity code. Where or how can I set the parameters when using Bytecode? Thanks.

Hmm, that seems to be so... If you want to deploy a contract that needs parameters in the constructor, perhaps getting Remix's "Web3 provider" working, to connect it to your local Geth/Wallet node, as then you can use Remix's form for creating the contract with parameters.

@kingassune Publishing the contract's source code would be a good step toward proving good intent; saying donors will get some goodwill tokens is fine to say, but there's no proof to back that up.

There is no reason to dump ether into unknown entities.

And from your nickname, @kingassune, I'll assume that "Assune, Inc." is just you; is it actually a registered company? Much less a registered charitable organization? Do you have any outside proof you're not just going to keep all donated funds?
