I want to access / modify data from a contract from another contract. If you could help me understand the error that would be great!
I get the following error:
Untitled1:33:8: Error: Indexed expression has to be a type, mapping or array >(is function (address) constant external returns (bool,address,uint256,bool))
if (a.Owners[msg.sender].sub = false){
^------^
below is the code :
pragma solidity ^0.4.7;
contract abc{
struct Owner{
bool exist;
address owner;
uint share;
bool sub;
} // un owner as son address et son percent d'ownership
mapping (address => Owner) public Owners;
uint public no_owners;
uint public no_sub;
function abc(){ // a l'execution, l'ownership est transferer a l'excecuteur avec 100 shares.
//initate
}
function transfer(address to,uint amount){
//transfer ownership
}
}
contract cde{
mapping (uint => abc) all_cde;
uint public f;
function ask_subdivise(abc a){
//les different owners vont devoir lancer la fonction
// une fois que tout les owners on lancer la fonction, le lot est diviser.
if (a.Owners[msg.sender].sub = false){
a.Owners[msg.sender].sub=true;
a.no_sub+=1;
}
}
}
