/* Module : EXCEPTHANDLER.CPP Purpose: Implementation for a class which intercepts and logs details about unhandled exceptions such as access violations, stack overflows and division by zero. The class is based upon the February 2002 MSDN article called "Under the Hood: Improved Error Reporting with DBGHELP 5.1 by Matt Pietrek.

Now includes flags to limit what is displayed in the log file. 2. These flag values and the location of the log file can now optionally be configured at run time via registry values. PJN / 26-03-2003 1. Tidied up #pragma message text 2. Removed the unused variable m_bAppendToLog 3. Changed the default flags the class uses 4. Flag values and location of the log file can now optionally be configured at run time via an API in the XCPTHLR dll ifself. This is now documented and implemented in the XCPTHLR module. 5. Reworked the sample app to be a GUI based app, where you can change the crash handler flags manually. Also the crash is now generated by hitting a button. PJN / 27-03-2003 1. Now pulls in DbgHelp support via GetProcAddress. This makes the code more robust in the absence of the DbgHelp dll PJN / 19-04-2003 1. Now optionally writes out the raw machine code at each call stack frame 2. Now optionally writes out the raw stack at each call stack frame. 3. Now optionally writes out the process list on the machine 4. Now optionally writes out system details including Computer Name, User Name, Number of Processors, Page Size, lowest memory address, highest memory address, OS details, OS version, OS Build, OS service pack, OS type, Windows Directory, Windows System Directory, Registered Organisation and Registered User. 5. Now optionally writes out the environment strings 6. Tidied up some indentation and alignment problems. PJN / 20-04-2003 1. Removed usage of CRT function "_tcsicmp" in preference to lstrcmpi 2. Removed old unused pragma error entry 3. Now optionally writes out stats as returned from GlobalMemoryStatus 4. Code now requires a recent copy of the Platform SDK to compile 5. Now optionally writes out display device stats 6. Now optionally writes out Code page stats 7. Now optionally writes out Locale and language stats 8. Now optionally writes out boot type PJN / 22-04-2003 1. Fixed a problem in LogRawMemory which was causing an access violation. 2. Now uses GetDC and GetDevCaps to report screen settings instead of EnumDisplaySettings as a more reliable mechanism. PJN / 01-06-2003 1. Now optionally logs the File Version details for all processes and dlls which are included in the log files. PJN / 19-11-2003 1. Fixed a bug in CExceptionLogger::GetAddressDetails in the usage of VirtualQuery. Thanks to Fredrik Savander for reporting this problem. PJN / 21-07-2006 1. Updated copyright details. 2. Integrated the functionality of _EXCEPTION_LOGGER_DATA into the CExceptionLogger class 3. Code now uses newer C++ style casts instead of C style casts. 4. Updated the code to clean compile on VC 2005 5. Now includes support for logging of Windows Longhorn Server and Windows Vista 6. Now includes support for logging of Windows Server 2003 R2 9. Now includes support for logging of various suite flags including: Embedded, Storage Server, Security Appliance, BackOffice components, MS Small Business Server, Enterprise Edition, Terminal Services, Datacenter Edition, Home Edition, Web Edition, Media Center Edition, Tablet Edition 10. Updated documentation to use the same style as the web site. 11. Now logs the GDI and User object count. 12. Now reports Page Faults, Peak Working Set Size, Working Set Size, Peak Paged pool, Paged pool usage Peak Non-paged pool usage, Non-paged pool usage, Peak Pagefile usage and Pagefile usage. 13. Now reports if running on Wow64 14. Now reports the process handle count 15. Now reports if the process is running in a terminal services environment 16. Now reports the Terminal services Session id value 17. Updated code to work correctly for x64 Windows. 18. Exception log file can now be accessed by other apps while CExceptionLogger is writing to it. 19. Now reports the info returned from GetNativeSystemInfo 20. Now reports the info returned from GetSystemWow64Directory 21. Now reports if 3D-Now, cmpxchg, Floating point software emulation, Pentium FDIV bug, MMX, DEP, PAE, RDTSC, SSE, SSE2, SSE3, cmpxchg16b and cmp8xchg16 are supported 22. Now reports the Shared Windows directory 23. Now reports if the program is running on the Terminal Services session currently attached to the physical console 24. Now reports on various Terminal Services values returned from WTSQuerySessionInformation 25. Now reports the total number of pages commited by the system, the current maximum number of page commits, the maximum number of page commit totals since last reboot, the total amount of physical memory in pages, the amount of physical memory available to user process in pages, the total amount of system cache memory in pages, the total amount of the sum of paged and nonpaged kernel pools in pages, the total amount of paged kernel pool in pages, the total amount of nonpaged kernel pool in pages, the size of a page, the total number of open handles, the total number of processes and the total number of threads. 26. Added support for returning information from WTSQuerySessionInformation. 27. Memory dump is shown as upper case hex now. 28. Now reports the info returned from GetCurrentHwProfile 29. Segment registers are now shown as 4 byte values PJN / 22-01-2008 1. Updated to support creating minidumps 2. The location for the logging file and the minidump file is now your temp directory. This means that files will be correctly created even with least-privileged user account
