A C++ wrapper class for "Cards.dll"
Welcome to CPJNCards, a simple C++ wrapper for "Cards.dll". This DLL provides
the functionality which the cards games supplied with Windows such as Solitaire
and FreeCell use to draw their playing cards. The API exposed from "Cards.dll"
is semi-documented and was originally described in an MSDN article in 1996 by
Dave Edson. Online examples which show you how to use the DLL from C# are
http://www.catch22.net/tuts/cardtut.asp. This class provides a very simply
C++ wrapping of the API to get you started writing your Playing cards game in
your C++/ MFC apps.
- Simple and clean C++ interface.
- The code looks after all the details of loading and obtaining the function
pointers and exposes a simple set of functions via the class. Internally the
class loads the DLL and uses GetProcAddress calls.
- 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
The enclosed zip file contains the CPJNCards source code and a simple
dialog based application which
exercises the class.

- Please note that cards.dll is not present on versions of Windows
since Windows 7. As such I have discontinued
development of this code and it is considered obsolete.
