So you need the interface of CMap and the implementation of std::map..? If so, then you need to declare your own CMyMap with an std::map member variable declared in it, and try to implement CMap similar functions in your CMyMap. However, you cannot simulate hash code related functions of CMap via a std::map.. Did I understand your problem correctly? -- Arman

How are you concluding that CString isn't releasing memory? Are you using some kind of a utility that is reporting it? If yes, then I think that your utility sucks and you should stop using it. It is a crappy thing, but it's life -^ Carlo Pallini

Neither here nor the other time you asked this question have you given any objective evidence of why you believe there to be leaks in CString. As I stated before, look at your own code - the likelihood of your code being incorrect is much, much higher than the likelihood of the code in MFC being incorrect, especially when it's a version of MFC that's had 11-12 years of exposure.

Nowhere in your code are you directly calling new or delete. It seems the problem and the code snippet you've shown are not related. "Old age is like a bank account.
