Addition of reset statistics button on toolbar (and menu). This buttons resets all times and visit counts to zero. Added due to beta test feedback.
Potential deadlock during hooking algorithms, prevented.
Improved detection of functions in code sections. Previous algorithm had the potential to incorrectly identify data in code blocks as code. New algorithm use new PDB API to correctly identify functions.

Improved Line Timing display - shortest time of not visited lines now displayed as zero.

Hooked Source Files tab on setting dialog allows you to specify source files that should not be hooked or that should be hooked, allowing you to exclude parts of your application or to concentrate on parts of your application. This allows you to provide function and line timing on a per file basis. Be aware that if the class and function filter is setup at the same time you may end up filtering out all files/functions and no data will be collected at all - it is up to you to choose the appropriate settings for your application.

New Relations tab, displaying time consuming (or most visited) functions, their child functions and their parent functions.
New Line Timing tab, displaying times for individual lines.
New settings tabs to control line timing hooks.
New dialogs for launch, inject, wait (for both wizard and dialog modes)

Version 0.10

Version 0.10 has the following improvements and changes.

wWinMainCRTStartup or equivalent is now correctly hooked when attaching via CreateProcess(). This results in the majority of hotspots beign grouped under the main worker thread. All other hotspots are grouped per thread. DLL loads appear as separate hotspots at present.
Cursor right, cursor left and return key can now be used to expand, collapse and toggle the expand state on the hotspots and analysis tree controls.

Bug fix for multiple hooking methods with the same name in different DLLs ("operator new" is an example).
The hooking method for all functions for performance monitoring has been improved, and now handles exceptions correctly.

Version 0.07
Version 0.07 includes the following new functionality:

Extra error reporting relating to symbol tracking on diagnostic tab.
Bug fix for "automatically add to PDB search path". Paths are reset to match the file settings dialog/wizard prior to launching/injecting/waiting on an application. Paths are then rediscovered. This means that for situations where you have multiple versions of the same DLL in your development environment, the correct paths to your PDBs are used, rather than paths to PDBs in potentially other directories on your system than the particular DLL in use at the time.
Internal minor bug fixes.

Version 0.06

Version 0.06 has the following improvements and changes.

Robustness improvement for boundary condition on memory mapped file.

Fixed function hooker bug which meant that for some apps/modules no functions would be hooked.
Fixed structured exception handling bug which meant that if your application threw an exception, the profiling hooks would prevent the exception from being handled correctly.
Fixed various statistics display bugs.

Version 0.02

Version 0.02 has the following improvements and changes.

Improved handling of version.dll.
Internal bug fixes for tracking data.

Version 0.01

Initial beta version of Performance Validator made available to selected beta testers. We would like your feedback on any bugs you may find, on the features and benefits of the software, and also feedback on features that you think are missing from the software but which you would find useful.

NT Service support is still under development. You can link to the NT Services Performance Validator support DLLs but don't expect Performance information to be displayed for services.

Help topic IDs are currently not correct.
