pointers and containers

[vblanco]

When i put a pointer in a container(std::list) and then retrieve it from another object the pointe is the same but i cant access the object.

example
std::list<myobject*> list
list.push_back(pobject1)//myobject*opbject1
in visual studio says pointer is 0x12345678

from another object i get the list

myobject*pobject2 = list.back() //to get the pointer

the pointer is 0x12345678, same as above

when i do pobject2->something() throws errors, and if i put a breakpoint and check the pointer the values are all COMPLETELY MESSED UP

it gives me a HUGE problem in my application and i hope someone will help

Use

Code: Select all

myobject*pobject2 = list.back(); //to get the pointer

I GET the pointer corectly, the problem is that variables and other things are messed up, i just write the code above badly

could it be that you delete the object you are pointing to at some time between storing and accessing?
A little bit more of your code would also help to figure out the porblem.

Possibly stupid question but sometimes easily missed, are the setter and fetcher in the same library/executable? If not, make sure everything is cleanly rebuilt to the same headers.

How do you create the object? With new?
