Hi ,

In a DLL, I use GlobalAlloc to allocate my data structure. And pass the pointer CPtrArray *m_ptr using
::PostMessage(hMainProgram, WM_MY_REGISTERED_MESSAGE, WM_MY_DATA, (LPARAM) m_ptr);

In main program, it can get all the data of CPtrArray, but when the program close, it will stop at assembly int 3

Thanks

Solution 1

If your "main program" is running in another process
you should use the Shared Memory (or COM transfer) :)

Elsewise (the "main program" is running in the same process)
you could pass an allocated by new pointer
and delete after the usage in the reaction function :)
