@swatarianess

Bung
@bung87
but sendTransaction yet not work out,That`s my question
Steve
@swatarianess
have you tested out your code in Remix?
Bung
@bung87
yes,just got two warnings
Steve
@swatarianess
what were the warnings?
Bung
@bung87
Gas requirement of function browser/ballot.sol:MyAdvancedToken.sell(uint256)unknown or not constant.
MyAdvancedToken.MyAdvancedToken(uint256,bytes32,bytes32): Potentially should be constant but is not.
Steve
@swatarianess
not sure about the 2nd warning, but with the first one i get for a few of my functions
Bung
@bung87
The contract I created just the short version of official example,as It just warning level message I think it does not matters the contract development
any idea about my question?
Steve
@swatarianess
hmm looking at the contract example code
you bought enough tokens to sell with the currently unlocked account, correct?
Bung
@bung87
ins.balanceOf myaccount is 10,the transaction I want send data is ins.sell.getData(10)
then I send transaction with from myaccount address to contract instance address with the data above
Bung
@bung87
and the contract instance contains 20 wei,and the price for sell is 1,10 tokens just costs 10 wei
Steve
@swatarianess
and when you do that you get an invalid address error?
Where did you deploy the contract? Testnet ?
Bung
@bung87
no , invalid address just occurs when I call ins.sell(10),
transaction result like other transaction returns,I deploy it on private network

Hi there, how can i connect a UI to my crowdsale contract that will display all the relevant info of my crowdsale to a user going to my site? ie. number of tokens available, token price, amount raised, ect... i cannot find a guide on how to do it anywhere.

@N-B-V
So after asking my question if figured it out :) --- etherscan.io sees all public tokens and have API's to interact with them. just incase anyone was wondering.

manu4github
@manu4github
i have a question if 100 transactions were called for my contract from 100 different people , is there any way to build cost efficiently, like sending multiple transactions in one transaction.

is there any source to get testnet (ropsten) ether sent to my testnet address? or do i have to ask ppl to give each time?
my mist wallet seems to be stuck on 99%

@Ectsang There is a testnet ether faucet for both Ropsten and Rinkeby. Google for it.
