• C++ Tools
• Win32 Tools
• IO Tools
• Registry Tools

Version 7.4

• Remove support for Visual Studio 2015.

Version 7.3

• Removed seldom used and untested aspects of the library. Contact us if you relied on functionality that is no longer present in this release.

Version 7.2

• Removal of manual "#define include guards" now that all supported compilers support pragma once.
• Removal of out of date lint directives.
• Added support for Visual Studio 2022 Preview.

Version 7.1

• Preparations for making the code compile on other platforms.
• Switch to using JetByteTools::Core::CReferenceCount for reference counts.
• Switch to using JetByteTools::Core::ErrorCodeToErrorMessage() rather than JetByteTools::Win32::GetLastErrorMessage()/li>

Version 7.0

• Major changes due to preparations for multi-platform support. Addition of CoreTools library which contains all cross platform code that was previously in Win32Tools.

Version 6.9.5

• Added support for Visual Studio 2019 (16.5 - 16.9).
• Updated project files to make release build optimisations consistent.
• Rationalised precompiled header usage.
• Removed unrequired includes.
• Began to move towards removing JetByteTools\Win32Tools\Utils.h by splitting it into more functionally cohesive headers.
• Changes to avoid explicitly catching JetByteTools::Win32::CSEHException now that it derives from JetByteTools::Win32::CException.

Version 6.9.4

• Added support for Visual Studio 2019 (16.4).

Version 6.9.3

• Fixed issued raised by Resharper++
• Changed include path separators from \ to / so as to support compilation on Linux using CLANG
• Fixed case of include file names to aid portability.
• Migrating code towards 'modern C++' idioms.
• Suppress warning C4355 "'this': used in base member initializer list" in Warnings.h and remove per file suppressions. We just use this idiom far too often for it to be a special case.
• Added support for Visual Studio 2019 (16.3).
• Dropped support for Visual Studio 2013.

Version 6.9.2

• Added support for Visual Studio 2017 (15.6 - 15.9).
• Added support for Visual Studio 2019 (16 - 16.2).

Version 6.9.1

• Added support for Visual Studio 2017 15.5.

Version 6.9

• Fixed issued raised by CppDepend
• Fixed issued raised by Resharper++

Version 6.8

• Made pragma once unconditional in headers.
• Fixed issued raised by PC-Lint Plus.
• Fixed issued raised by CppDepend
• Fixed issued raised by Resharper++
• Use override rather than virtual for implementations of virtual functions in derived classes.
• Added new headers JB_MSCoreE.h and JB_ATLBase.h which wrap the system headers and which contain comments that will help you set up the build environment in situations where these system headers are not available.

Version 6.7

• No changes.

Version 6.6.6

• No changes.

Version 6.6.5

• No changes.

Version 6.6.4

• No changes.

Version 6.6.3

• Ran Visual Lint using Gimpel PC Lint on all code and adjusted to remove warnings and fix bugs.
• Removed all use of exception specifications. We only ever used throw() but that's now gone too.
• Protected non-virtual destructors on interfaces are now virtual even though they you can't delete the object via the interface.
• All destructors that could throw exceptions now have optional "log and swallow" exception handlers which are enabled by default. This is better than ignoring the problem and being faced with a call to std::terminate() which can be hard to track down.

Version 6.6.2

• Changes to remove non-trivial, function level static objects from the code, the construction of which is problematic in multi-threaded code.
• JetByteTools::CLRHosting::CCLRHostFactory::EnumerateLoadableRuntimes() now skips the "IsStarted()" test for both v2.0.50727 and v1.1.4322 of the CLR. Previously you would get an error if v1.1.4322 was installed.
• JetByteTools::CLRHosting::CCLREventSink::OnEvent() now calls JetByteTools::CLRHosting::IEventSinkCallback::OnException() if an exception is thrown during processing. This is called from within the exception handler so that you can rethrow and re-catch if you need to work out what the exception was.
• All JetByteTools::CLRHosting::CHostPolicyManager events now call JetByteTools::CLRHosting::IHostPolicyManagerCallback::OnException() if an exception is thrown during processing. This is called from within the exception handler so that you can rethrow and re-catch if you need to work out what the exception was.
• Bug fix in JetByteTools::CLRHosting::CCLRStrongName::StrongNameTokenFromAssembly() we now correctly convert the filename from a _tstring to a wide string.

Version 6.6.1

• No changes.

Version 6.6

• Added 'crt has shutdown' tests to all COM objects that we can pass to the CLR and which it can hold on to until after the CRT has been shutdown. We use the test (which is done by registering an 'atexit()' function) to work out if we can use any CRT services when callbacks are made from the CLR to our COM objects. This prevents horrible crashes if the CLR decides to call ExitProcess() and cause the CRT to shutdown before it has finished calling into our COM objects. The following objects are affected: JetByteTools::CLRHosting::CCLREventSink, JetByteTools::CLRHosting::CHostPolicyManager.
• Added JetByteTools::CLRHosting::CCLRHost::OnCLRDisabled() which is called if the CLR is disabled and which sets a flag that stops us trying (and failing) to stop the CLR in JetByteTools::CLRHosting::CCLRHost::Stop().
• Added JetByteTools::CLRHosting::CCLRHostFactory::GetRuntimeByVersion().

Version 6.5.9

• Added JetByteTools::CLRHosting::CCLRStrongName and JetByteTools::CLRHosting::CCLRRuntimeInfo::GetCLRStrongNameInterface() to access the new .Net 4.0 strong name API.

Version 6.5.8

• No changes.

Version 6.5.7

• Updated our support of Visual Studio 2012 to the RTM version. Added a few more warning suppressions. Fixed the solution file format so that it's actually a 2012 solution file and not a 2010 solution file using the 2012 tool chain.

Version 6.5.6

• We now support Visual Studio 11. At present the code has only been tested with the beta version.

Version 6.5.5

• Fixed some warnings generated by /analyze.
• Adjusted how JetByteTools::CLRHosting::CException::GetErrorMessage() deals with HRESULTs that are actually just Win32 errors.
• Bug fix. Potential buffer overflow in JetByteTools::CLRHosting::CException::GetErrorMessage()
• Bug fix. Memory leak, delete rather than delete [] in JetByteTools::CLRHosting::CHostAssemblyManager::GetNonHostStoreAssemblies()

Version 6.5.4

• No changes.

Version 6.5.3

• No changes.

Version 6.5.2

• No changes.

Version 6.5.1

• No changes.

Version 6.5

• Added JetByteTools::CLRHosting::CCLRGCManager and added support for it into JetByteTools::CLRHosting::CCLRHost.
• Bug fixes to JetByteTools::CLRHosting::CHostPolicyManager which mean that the callbacks actually work correctly.
• Added support for FAIL_AccessViolation and FAIL_CodeContract.

Version 6.4

• JetByteTools::CLRHosting::CException now uses LoadStringRC() again. It does actually help to display some error messages.

Version 6.3.3

• More fixes to JetByteTools::CLRHosting::CCLREventSink and JetByteTools::CLRHosting::CCLRHost to remove a race condition during host shutdown which could have caused a purecall due to events being fired after the event sink has been destroyed. I think I've got it this time!

Version 6.3.2

• Fixes to JetByteTools::CLRHosting::CCLREventSink and JetByteTools::CLRHosting::CCLRHost to remove a race condition during host shutdown which could have caused a purecall due to events being fired after the event sink has been destroyed.

Version 6.3.1

• No changes.

Version 6.3

• Lots of white space changes which make comparing actual changes with 6.2 quite hard. Sorry.
• Catch potential exceptions in the destructor of JetByteTools::CLRHosting::CCLREventSink.
• Added JetByteTools::CLRHosting::CCLREventSink::DisableCallbacks() which prevents future events from being passed on to the callback interface. Useful during shutdown.
• Adjusted how JetByteTools::CLRHosting::CCLRHost is constructed and how it manages its subobjects.0
• Added support for accessing the CLR's policy manager, via JetByteTools::CLRHosting::CCLRHost::GetPolicyManager().
• Added JetByteTools::CLRHosting::CCLRHost::StartIfPossible() which is like Start() but returns false rather than throwing an exception if the CLR is already running.
• Added JetByteTools::CLRHosting::CLRHostFactory which can be used to create hosts using either the .Net 2.0 hosting API or the .Net 4.0 hosting API.
• Adjusted JetByteTools::CLRHosting::CLRMetaHost so that it links dynamically with CLRCreateInstance() so that code built with it can still run on platforms that do not have .Net 4.0 installed.
• Added JetByteTools::CLRHosting::CLRMetaHost::CanCreate() which returns true if CLRCreateInstance() is available an the .Net 4.0 hosting API can be used.
• Added JetByteTools::CLRHosting::CCLRPolicyManager which allows access to the CLR's policy manager and provides functionality to set the error handling and escalation policies for a host.
• Added JetByteTools::CLRHosting::CCLRRuntimeInfo::SetDefaultStartupFlags().
• Added JetByteTools::CLRHosting::CCLRRuntimes
• JetByteTools::CLRHosting::CException no longer uses LoadStringRC() which never seemed to do much any way. The reason for the removal is that it's a .Net 2.0 API and it probably shouldn't be used when we're using the .Net 4.0 API.
• Added JetByteTools::CLRHosting::CHostPolicyManager which allows the CLR to inform the host of various policy issues.

Version 6.2

• Added some initial support for the new hosting API with JetByteTools::CLRHosting::CCLRMetaHost and JetByteTools::CLRHosting::CCLRRuntimeInfo.

Version 6.1.1

• No changes.

Version 6.1

• No changes.

Version 6.0

• Added JetByteTools::CLRHosting::CException which we now use in place of JetByteTools::COM::CException. This exception class tries quite hard to get meaningful error description strings from the CLR dlls; it doesn't always work though :(.
• We now include mscoree.h directly rather than including the Admin library wrapper. The wrapper was only required for VC6 and has now been removed.

Version 5.2.5

• No changes.

Version 5.2.4

• No changes.

Version 5.2.3

• No changes.

Version 5.2.2

• No changes.

Version 5.2.1

• No changes.

Version 5.2

• Initial revision
