CScreenSaver v1.02 An MFC class framework for developing screen savers

The screen saver library provided in the Windows SDK namely SCRSAVE.LIB is designed for SDK apps and cannot be used with traditional MFC apps. CScreenSaver provides an MFC class framework to allow screen savers to be built using "normal" MFC code.

Features

• Simple and clean C++ interface.
• The code uses standard MFC concepts to allow screen savers to be created. This includes CWinApp and CWnd derived classes and C++ virtual functions.
• The code is Unicode enabled and build configurations are provided.
• The code handles the differences between Windows 9x and NT/Windows 2000 screen savers with regard to passwords transparently.
• The code is multi - monitor aware.

The enclosed zip file contains the CScreenSaver source code and a sample screen saver application which exercises the classes.

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 (5 May 2000)

• Initial public release.

V1.01 (6 January 2006)

• Updated the copyright details and general code cleanup.
• CScreenSaverApp::ChangePassword method now returns a BOOL to indicate success.
• Fixed a number of issues when code is compiled using the "Detect 64 bit portability issues" in Visual Studio .NET 2003. To address this issue, it does mean that you require the Platform SDK to be installed and configured if you want to compile the code in Visual C++ 6.
• Removed some unnecessary comments from CScreenSaverApp::ShowConfigureDialog.
• Fixed a bug in CScreenSaveWnd::OnClose where it would incorrectly prompt for a password when the screen saver preview was being displayed and you were running on Windows 9x. Thanks to Jason Yang for reporting this bug.
• Updated the documentation to use the same style as the web site.

V1.02 (18 July 2006)

• Code now uses new C++ style casts rather than old style C casts where necessary.
• Replaced calls to ZeroMemory with memset
• Reviewed TRACE statements for correctness
• Verified code compiles cleanly on VC 2005
• Addition of CSCREENSAVER_EXT_CLASS preprocessor macro to allow the classes to be easily added to an extension dll.
