CClockCtrl v1.06 An MFC class to display
an analog clock
CClockCtrl is an MFC widget which renders an analog clock. The class is based
in part on the class of the same name from the book "MFC Programming with Visual
C++ 6.0". The class is derived from CStatic and a number of public methods
allow customisation of its look.
The enclosed zip file contains the CClockCtrl
source code and also includes a VC 6 workspace file to build a small demonstration

V1.04 (11 August 2001)
- Removed Win2k Build configurations and instead put in code into sample app
to at runtime, detect if the OS provides transparency support. This means that

- Second hand can now be updated with sub second precision with the "SetSubSecondPrecision"

some of the new window layering API's. To get the sample app to work on Win9x
or NT 4, recompile the code using one of the non Win2k build configurations.
