Contract Address is not Showing and How to Send ETH from Contract Address to Contract Creator

Question

Q-1: I,m new in Ethereum Bockchain,I have Created my new token that can be get by send from 0.01 to 1 ETH instant. When i did transaction in transaction hash Tokens Transferred From line showing 0x000000000.. If any need to addition in solidity code please suggest. Below is code and transaction hash.

Q-2: When anyone buy token instant to send 0.01 to 1 ETH than ETH going to my contract address and i don't know how i can send into creator address . Please help how i can send to my creator address.

Answer 1

You need to call the withdraw() function to transfer the ETH sent to the contract to the owner account.

function withdraw() onlyOwner public {
    address myAddress = this;
    uint256 etherBalance = myAddress.balance;
    owner.transfer(etherBalance);
}

Answer 2

Ans 1 : You are supplying total supply of token must belong to some address like Owner and when we transfer that token it will emit transfer event witch specify sender,receiver,amount but in you case sender = address(0) == 0x0000000000000000000000000000000000000000. That's why this is showing you that address. For correction update distr function.

function distr(address _to, uint256 _amount) canDistr private returns (bool) {
    // Check owner has amount to transfer.
    require(balances[owner] >= _amount);
    totalDistributed = totalDistributed.add(_amount);        
    balances[_to] = balances[_to].add(_amount);
    // Owner transfer amount and reduce token balance
    balances[owner] = balances[owner].sub(_amount);
    emit Distr(_to, _amount);
    // emit Transfer function (sender == owner)
    emit Transfer(owner, _to, _amount);

    return true;
}

Ans 2 : You need to add owner.transfer(msg.value); in getToken() function.

function getTokens() payable canDistr  public {
    uint256 tokens = 0;

    // minimum contribution
    require( msg.value >= MIN_CONTRIBUTION );

    require( msg.value > 0 );

    // get baseline number of tokens
    tokens = tokensPerEth.mul(msg.value) / 1 ether;        
    address investor = msg.sender;

    if (tokens > 0) {
        // if token transfer to caller account, ether will be transfer to 
        // contract owner's account.
        require(distr(investor, tokens));
        owner.transfer(msg.value);
    }

    if (totalDistributed >= totalSupply) {
        distributionFinished = true;
    }
}
