What Happened to Debugging Books?
Monday, December 29th, 2008Last quarter was very busy for me and to keep up with schedule I now employ pipeline book writing techniques borrowed from CPU of my laptop to work simultaneously on 10 books. I also feel more relaxed with take it easy attitude towards writing and publishing: TIEP - TIE Publishing. In summary: the following book is planned to be released in Q1, 2009 where I’m an author:
-
- Windows® Debugging: Practical Foundations (ISBN: 978-1906717100)
A magazine issue is planned for Q1 where I’m an editor:
-
- March issue of Debugged! MZ/PE: MagaZine for/from Practicing Engineers (ISBN: 978-1906717384)

Crash2Hang
Monday, December 29th, 2008Sometimes there is a need to preserve a crashing application or a service from termination and keep it in memory without showing any GUI dialogs or message boxes. Here Crash2Hang tool comes handy. It is free and can be downloaded from here:
The source code is simple as possible:
// Crash2Hang
// Copyright (c) 2009 Dmitry Vostokov
// GNU GENERAL PUBLIC LICENSE
// http://www.gnu.org/licenses/gpl-3.0.txt
#include <windows.h>
int main(int argc, WCHAR* argv[])
{
if (argc > 1)
MessageBox(NULL, L"One of processes has called a postmortem debugger!", L"Crash2Hang", MB_OK | MB_ICONSTOP | MB_SETFOREGROUND);
else
Sleep(INFINITE);
return 0;
}
The tool can be used as a postmortem debugger specified in AeDebug registry key, for example, instead of CDB. Any argument specified to Crash2Hang.exe causes it to display a message box when launched
and exit process upon its dismissal. If several threads in a problem process experience an unhandled exception then Crash2Hang process is launched several times which may result in several such message boxes. Without arguments Crash2Hang process hangs infinitely causing the problem thread with an unhandled exception to hang indefinitely too (see my old post Who calls the postmortem debugger? for explanation).
