For example, it enables an application to perform data recovery and cleanup operations such as capturing application state and releasing resources before termination. It also allows developers to specify that WER should automatically restart an application that it has terminated. In this screencast, Kate Gregory (@gregcons) provides an overview of ARR on Windows 7. Kate also demonstrates how to integrate ARR into your native applications via Win32. Update (March 22, 2011 - 5:40 PM): The Windows Restart and Recovery Recipe is now available to download. en Tue, 21 May 2013 16:16:58 GMT Tue, 21 May 2013 16:16:58 GMT Rev9 Re: Application Restart and Recovery on Windows 7 in Native Code posted by Mr Crash

And, don't worry: more C++ stuff is on the way! Let me know if there's anything in particular that you'd like to see!

We have one more in the hopper.

Um doing it in MFC shouldnt count as native code...

But why ? Scared

In NativeTestDlg.cpp there is a memory leak on line 66 (the memory pointed to by former doc is lost).
In NativeTestDlg.cpp there is a memory leak on line 70 (the memory pointed to by rrh lost).
CNativeTestHarnessDlg has no destructor, so the memory pointed to by doc leaks.
NativeAndRestartRecovery.h there is a potential memory leak on line 66 if the supplied 'T::operator >>' throws.
If you dont want to handle it, use RAII (in these cases unique_ptr or shared_ptr or even auto_ptr, since the code was written a year ago).

Another problem I see is that the recovery may fail due to dead lock/races as your program is in an undefined state and you launch a new thread; what if the program crashes in HeapAlloc due to Heap corruption or your gui is not responding but some thread is updating the recovery document structure.
These problems seem not to be handled by this 'recipe', but I dont know what magic Windows does under the covers. Another issue are Blue Screens or power failures. So it would be still appropiate to save application state as the application is in a known state.

But I might have missed the point of this cast.
