CHKLM v1.17 An MFC class to write to HKEY_LOCAL_MACHINE (Obsolete)

Welcome to CHKLM, A simple MFC class to allow you to write values to the HKEY_LOCAL_MACHINE registry key instead of HKEY_CURRENT_USER which the MFC functions limit you to. The class is not designed to be a complete registry class, instead it provides functions similar in style to the MFC ones.

Full source code is provided for those interested. A VC 6 workspace file is included which builds a simple demo console application which calls the class methods.

Features

• Simple and clean C++ interface based upon the MFC functions
• The classes are fully Unicode compliant and include Unicode built options in the workspace file.
• Full documentation is provided in the form of a HTML file

The enclosed zip file contains the CHKLM source code and a simple console based application which exercises the class.

Copyright

• You are allowed to include the source code in any product (commercial, shareware, freeware or otherwise) when your product is released in binary form.
• You are allowed to modify the source code in any way you want except you cannot modify the copyright details at the top of each module.
• If you want to distribute source code with your application, then you are only allowed to distribute versions released by the author. This is to maintain a single distribution point for the source code.

Updates

V1.0 (27 June 1998)

• Initial public release.

V1.01 (14 July 1999)

• Now ships with a VC 5 workspace instead of VC 6.
• Tidied up the documentation file.
• Unicode Build configurations now actually compile and work <g>.

V1.1 (3 October 1999)

• Addition of GetProfileStringArray and WriteProfileStringArray methods.

V1.11 (9 August 2001)

• Updated copyright message
• Fixed an issue where the class fails to read any key that is readonly. This is a problem since Win2000 defaults access to HKLM for "normal" users to readonly. Thanks to Hans-Georg Ulrich for spotting this problem
• Removed an unreferenced function from the hklm header file
• Fixed a memory overwrite problem in CHKLM::SetStringArrayIntoRegistry. Thanks to BoundsChecker on spotting this problem.
• Fixed a problem in CHKLM::SetStringArrayIntoRegistry with the calculation of the size to be used in the call to RegSetValueEx
• GetStringArrayFromRegistry now use RegQueryValueEx to get the size of the data it contains.
• Sample app has now uses CWinApp to make it easier for testing.

V1.12 (12 October 2001)

• Now allows application name to be overridden using new method namely, SetProductNameRegistryKey. Thanks to Rene M. Laviolette for this suggestion.

V1.13 (23 July 2004)

• Now ships with a VC 6 workspace instead of VC 5.
• Fixed a simple 64 bit INT_PTR compilation warning when compiled in VC 7.1

V1.14 (11 November 2004)

• Fixed a compiler warning when Force conformance in for loop option is set in VC 7.1
• Addition of a HKLM_EXT_CLASS preprocessor macro which allows the class to be easily added to an extension dll

V1.15 (26 March 2005)

• Addition of a m_bProfileWriteFlush variable to the clas which dictates if the registry settings should be commited immediately as oppossed to relying on the lazy writer.

v1.16 (11 June 2006)

• Fixed a bug in CHKLM::WriteProfileBinary where the optional flushing was being done after the registry key was closed.
• Updated copyright details.
• Updated the documentation to use the same style as the web site.
• Please note that I have discontinued development of this code. Instead please check out AppSettings, a collection of classes to encapsulate Application settings which implements a much bigger superset of the functionality provided by CHKLM.

V1.17 (20 July 2006)

• Code now uses newer C++ style casts instead of C style casts.
• Updated the code to clean compile on VC 2005
