    V1.0 (21th April 1998)
    • Initial public release.

    V1.01 (4th January 1999)

    • Minor update to the documentation.
    • Provision of a VC 5 workspace file now as standard.
    • UNICODE enabled all the code.
    • IPENUM now uses MFC DLL and C Runtime DLL's instead of statically linking. This means that the IPENUM executable requires these files to be installed. If you haven't already got the MFC 4.2b DLLs on your machine (MFC42.DLL in your Windows system directory), then grab them from Microsoft's web site at

    To use the MFC class CIPEnum in your own code, simply include the ipenum.cpp module in your project and #include ipenum.h file in whichever of your modules require it. You will then need to derive your own class from CIPEnum and override the pure virtual function EnumCallbackFunction(). Further information about this function is included below. To see this in action, have a look at the CMyIPEnum in the module main.cpp.


    virtual BOOL CIPEnum::EnumCallbackFunction(int nAdapter, const in_addr& address)=0;

    Return Value:
    TRUE if the the enumeration of the IP addresses should continue, FALSE to stop enumeration.


    • nAdapter -- The index of the IP address being returned. This value will be incremented each time your callback function is called.  The value will start from 0.
    • address -- The IP address for the current adapter. For further information about this structure have a look at the Win32 SDK documentation.
