wierd Memory Leaks !!

[nawaf]

HeLLo Guys,
I'm having a bit of a problem here, I finsihed coding my program, it works corectly, but after finshing the debugging, MS VC++ 6.0 just gives me a message in the output pane :
etected memory leaks!
Dumping objects ->
{318897} normal block at 0x00AB4E00, 104 bytes long.

but I'm sure I deleted every object I allocated dynamically, what is it, I don't find where the leak is, could anyone help me please ?
Thanks

Take care with the objects allocated dinamically in Constructors, Copy constructors or operators, also with the objects dealocated in destructors.

Some of these, may be called by the program in a masked way and you may have memory leaks.

Hope this helps,

What got me one time was CException. If you are catching a CException, you must call the Delete() function of the exception. Check to see if you are catching any of these or any classes that inherit from this.

You can use smart pointers and autopointers instead of pointers. John Fill

HeLLo,
Mr. JohnFill , can you please clarify what do you mean by smart pointers and auto pointers?
Thanks

 

[Cagliostro]

autopointers are pointers from STL. You use them like
#include<iostream>
#include<memory>
using namespace std;
int main()
{
auto_ptr<int> x;//quite the same as int* x
x=new int;
*x.get=100;
cout<<*x.get();
return 0;
}
The smart pointers are Microsoft specific templates from ATL, but are much more reliable. Is the same idea as in COM AddRef/Release John Fill

John, looks useful. Would there be a way to use auto or smart pointers using less verbose code then what I'm doing with regular code for dynamically allocated arrays. See thread116-107726 for details. If so, wanna give me a quick example?
