Hello!! Well, tried to cram in as much info as I could to the topic. Lets see if someone got it

I have this:

  
class cWarehouse
{
  cWarehouse();
// stuff

  cStorage m_Storage;
  cAutoTruck m_AutoTruckSolo;
  cAutoTruck m_AutoTrucks[5];
};

Both my cStorage and cAutoTruck has a constructor that takes one parameter, a cWarehoue pointer. This because I want them to know who "owns" them, and so they can access their "brothers". Well, this works:

  
cWarehouse::cWarehoues()
  : m_Storage(this), m_AutoTruckSolo(this)
{
// stuff

}

But how do I do the same with the array of cAutoTrucks??? I''ve tried everything... (well, aparently not everything since it''s not working. Assuming there IS a way to make it work..) And yes I know I could do a cAutoTruck::SetWarehouse(cWarehouse* p_pWarehouse), but I don''t want to!

Please help! Thanx... "No lies of sugar can sweeten the sournes of reality" }+TITANIUM+{ A.K.A. DXnewbie[onMIRC]

anyone?..

I can''t find anyone who knows how to do this.

Also noticed that my question is very similar to this:

  int* i = new int[50]( parameter );

Isn''t that possible either?..

I don't believe there is a way to get elements of an array to construct using a constructor other than the default constructor. I think you'll need to create a container of your own. Perhaps like the one below.

  class cAutoTruckContainer : public std::vector<cAutoTruck>{public:    cAutoTruckContainer(int size, cWarehouse *owner)  {    for(int i=0; i<size; i++)      AddAutoTruck(owner);  }private:  void AddAutoTruck(cWarehouse *owner)  {    cAutoTruck autotruck(owner);    push_back(autotruck);  }};

And use it like so...

    class cWarehouse{  cWarehouse();// stuff  cStorage m_Storage;  cAutoTruck m_AutoTruckSolo;  cAutoTruckContainer m_AutoTrucks;};...cWarehouse::cWarehoues() : m_Storage(this), m_AutoTruckSolo(this), m_AutoTrucks(5,this){// stuff}

And keep in mind that if copying a cAutoTruck is non-trival you'll need to define a copy constructor.
