v1.1, An MFC class framework to encapsulate developing Control Panel Applets.
V1.0 (18 July 1999)
V1.1 (20 November 1999)
- Now fully supports
CPL_INQUIRE as well as
- Now supports a document template approach to creating applets. This means that you can
easily support multiple applets per dll using the CPL++ framework.
- Demo program now supports demo'ing both static and dynamic applets.
- Control panel applet now always output as a ".cpl" file instead of a ".dll" file.
- Now supports displaying the specified property page (via the
message) when a control panel applet is called via the
rundll32 command line.
To use CPL++ in your applets all you need to do is:
- Ensure your DLL has a DEF file and exports the sole function
Note: You do not need to write this function as it is provided internally by the
- Include cpl_pp.h and cpl_pp.h in your project (configured to produce
a standard DLL including MFC either dynamically or statically).
- Derive a class from
CControlPanelApp and override its
function. In it call
AddApplet() to add each applet you want. Normally,
you would do this just once, but for demonstration purposes, the sample creates two
- Each applet you add should be an instance of the class
It should be created on the heap. See
CApp::OnInit() for an example.
Depending on which constructor you call, you will have created an dynamic (responds
CPL_NEWINQUIRE) or static (responds to
- The code is UNICODE enabled and UNICODE build configurations are provided for the test applet.
