* History:
* 2005-07-27 v1 - First public release on http://www.codeproject.com/
- * http://www.codeproject.com/threads/stack_walker.asp
+ * http://www.codeproject.com/threads/StackWalker.asp
* 2005-07-28 v2 - Changed the params of the constructor and ShowCallstack
* (to simplify the usage)
* 2005-08-01 v3 - Changed to use 'CONTEXT_FULL' instead of CONTEXT_ALL
* - Added example for doing an exception-callstack-walking in main.cpp
* (thanks to owillebo: http://www.codeproject.com/script/profile/whos_who.asp?id=536268)
* 2005-08-05 v5 - Removed most Lint (http://www.gimpel.com/) errors... thanks to Okko Willeboordse!
+ * 2008-08-04 v6 - Fixed Bug: Missing LEAK-end-tag

+ * http://www.codeproject.com/KB/threads/StackWalker.aspx?msg=1434538#xx1434538xx
+ * Fixed Bug: Missing FreeLibrary call in "GetModuleListTH32"
+ * http://www.codeproject.com/KB/threads/StackWalker.aspx?msg=1326923#xx1326923xx
+ * Fixed Bug: SymDia is number 7, not 9!
+ * 2008-09-11 v7 For some (undocumented) reason, dbhelp.h is needing a packing of 8!
+ * Thanks to Teajay which reported the bug...
+ * http://www.codeproject.com/KB/applications/leakfinder.aspx?msg=2718933#xx2718933xx
+ * 2008-11-27 v8 Debugging Tools for Windows are now stored in a different directory
+ * Thanks to Luiz Salamon which reported this "bug"...
+ * http://www.codeproject.com/KB/threads/StackWalker.aspx?msg=2822736#xx2822736xx
+ * 2009-04-10 v9 License slihtly corrected (<ORGANIZATION> replaced)
+ * 2009-11-01 v10 Moved to http://stackwalker.codeplex.com/
+ * 2009-11-02 v11 Now try to use IMAGEHLP_MODULE64_V3 if available
+ * 2010-04-15 v12 Added support for VS2010 RTM
