Hi all,
      just want to know if any of you are familiar with this memory leak :

I just open my Dialog and close it...

Detected memory leaks!
Dumping objects ->
{41} client block at 0x004925D0, subtype 0, 64 bytes long.
a CDynLinkLibrary object at $004925D0, 64 bytes long
a CDynLinkLibrary object at $004925D0, 64 bytes long
Object dump complete.

Wow, how fun... :)

is your CDialog of the heap, if so delete it when you are finished with it

CDialogDerived *dd = new CDialogDerived();
dd->DoModal();
delete dd;

hopet this helps

Yes, i'm using 2 dll's ... but double-clik not working

The Dlg is on the frame...  

the dll's are loaded direct at the start... maybe they are the cause.... hmmmm...

Ok ... i'll try to look for a leak in the dll's... i'll keep you posted...

Hi Moonover,

maybe it's not a bug at all ... tak a look at this MSDN article:
'PRB: Memory Leaks Reported When Using Multiple MFC DLLs ID: Q167929'
http://support.microsoft.com/support/kb/articles/Q167/9/29.ASP

I agree with zoppo not all leaks reported are actually leaks

to test this put a breakpoint on the constructor of CDynLink and write down the address

then put a break point in  the destructor and see if it is called with the correct address of the original object - if the destructor is being called but it is still reporting as a leak then it is a 'feature' of the leak reporting.

This is made easier obviously if you only have 1 CDynLinkLibrary being created (1 per DLL) adn if it stays at the same allocation number (eg in your case {41} )
