IOS/Objective-C I can store objects in a local declared NSMutableArray. Why can’t I store them in same type of array in an object in another class?

'DrawObject' was not declared in this scope error using std::vector, trying to store class object (c++)

Trying to have my "layer" class, put 3 objects "drawObject", into it's vector, and getting out of scope error.


Everywhere I see they just do "vector >Class< vectorName"; and it works!


layer class:


#include <vector>
#include "DrawObject.h"
using namespace std;
class layer
{
public:
layer();
virtual ~layer();
private:
vector<DrawObject> objects; <--------------- Error here! "'DrawObject' was not declared in this scope"

Store and Retrieve array of custom class objects from shared objects.
Operating Systems
Hi,
I am stuck up with a problem in ActionScript 2. I am using Flash MX 2004 on windows XP.
I have created 3 custom classes say Parent, Child, and GrandChild. Parent class contains in it an array of its Child objects. Similarly each Child object contains in it an array of GrandChild objects. Also I do have one global array of all the Parent objects.
I want to store this array to the shared objects on specific events(say exiting the session) and then reload them from the shared object(on next session startup). I am able to store the global array to the shared object but when I try to retrieve the same array from shared object, I could not do
is there way to store all the objects of the class in the global array of objects in Parse in javascript
Operating Systems

Below is the code

Parse.initialize("HIL42pG8FRAx9AXasyyJAg5nXI6x2IifWh30AX5I","KUKOb5pz4GEbcbGAa8GVQrBQL7ER7DsV6m0PZLOL");

var queryGroups = new Parse.Query("Group");
var arr = []; 
queryGroups.find({
       success: function(objects) {
        for (var i = 0; i < objects.length; i++) {
            var g = new Object();
            g["whatsAppGroupName"] =
objects[i].get("whatsAppGroupName");
            g["whatsAppGroupDescription"] =
objects[i].get("whatsAppGroupDescription");
            g["entryCriteria"] = objects[i].get("entryCriteria");
            g["parent"] = objects[i].get("parent");
            arr.push(g);
        }

        for (var i = 0; i < arr.length; i++) {
            console.log("whatsAppGroupName = " +
arr[i].whatsAppGroupName);
        }       
       },
       error: function(error) {
           console.log("An error occured :(");
       }
});

Now the problem is that for loop which prints to console works fine inside find function but outside the find function for loop doesn't work, seems that data is not stored in the global array. So, is there way to store the data in the global array so that data can be used later. I have searched on the internet and google, but not able to find the better explanation.
