Hello,
 
It seems that you have declared a destructor as non-virtual, all our classes derived from CXTPFrameWndBase do not have their destructor called, thus making some memory leaks to our objects.
 
Here is your code :
 
 
In your file "XTPFrameWnd.h" :

class CXTPFrameWndBase : public CXTPCommandBarsSiteBase<TBase>
{
public:
    //-----------------------------------------------------------------------
    // Summary:
    //     Constructs a CXTPFrameWndBase object
    //-----------------------------------------------------------------------
    CXTPFrameWndBase()
    {
    }
    //-----------------------------------------------------------------------
    // Summary:
    //     Destroys a CXTPFrameWndBase object, handles cleanup and deallocation
    //-----------------------------------------------------------------------
    ~CXTPFrameWndBase() // !!!! Not virtual ???
    {
    }
...
 
 
Could you please check it and tell us if it is a bug ?
 
Thank you in advance,
Regards,
Sergio

Hi,
it is not bug. All CWnd derived classes have virtual destuctors. virtual keyword doesn't requried.

Hi,
 
Ok, then do you know why our destructor of our CMDIChildWnd is never called ?
 
Here is our code :
 
 
#define CChildFrameBase CXTPFrameWndBase<CMDIChildWnd>
 
class CLASS_DECL_FCORE CFMDIChildWnd : public CChildFrameBase
{
       DECLARE_DYNCREATE(CFMDIChildWnd)
protected:
       CFMDIChildWnd();           // protected constructor used by dynamic creation
       virtual ~CFMDIChildWnd();
...
 
Perhaps it's due to missing DECLARE_DYNCREATE(...) ?

We have temporarily placed our cleanup code inside method OnDestroy (WM_DESTROY), to avoid memory leaks.

Please tell us if you have more information about this destructor.
 
Thanks !

Sergio

Hi Oleg,
 
I finally found where was the problem. It isn't Codejock, it's our code :
 
        virtual void PostNcDestroy() {};   // in child.h
 
This is the method who calls "delete this;"...
 
Sorry for the disturb and thank you very much for your help,
Best regards,
Sergio
