Question

My application needs to scan 3rd party files that often leads to crash.
In order to overcome that, it uses a separate process to scan those files and
whenever this process crashes my application just instantiates another one.

My problem is that after each crash I get Windows crash message:
“AuxScanner has stopped working…”

How can I prevent this message and crash quietly?

I’m using named pipes for inter-process communication.

Thanks

See http://blogs.msdn.com/b/oldnewthing/archive/2004/07/27/198410.aspx: you can disable the program crash dialog (though you’ll need to do so from inside the sub-process).

The way I read it, you want something like this in your sub-process:

#include <windows.h>

//...

SetErrorMode(SetErrorMode(0) | SEM_NOGPFAULTERRORBOX);
//or if you only care about Vista or newer:
//SetErrorMode(GetErrorMode() | SEM_NOGPFAULTERRORBOX);

Interesting question by the way – this might be interesting to stick into all kinds of software during development; it’s quite annoying when your actively-developed code crashes (not unexpected), and then then everything waits, your UI changes focus, and it offers to (pointlessly) send a crash dump to microsoft…
