[Winpcap-users] dynamic loading of wpcap.dll

[Marcel van Lieshout]

yes, I know a driver is needed. I just want my dll to load correctly even when winpcap isn't installed. Of course, it wouldn't work but it would give me the possibility to inform the user.

thanks anyway

Marcel

  hi..
  see apart from loading wpcap.dll at runtime..
  that dll also requires som driver running in kernel mode ...(npf.sys(as i remember the name) in this case)
  otherwise it won't work...
  so u can do this thing u can put that file in the installation diectory and register that driver..or jus tell the user to install the required library files..
  i think that would work..
  bye.

    Hello,

    I'm writing a ethernet-chip simulatormodule using WinPcap. The simulatormodule is written as a dll, loaded when needed by the simulator_manager. To get the module-specifics, the manager loads/unloads all modules during an enumeration at simulator startup. Because my module uses WinPcap, wpcap.dll is loaded, too. This all works fine.

    Except...
    When WinPcap isn't installed (no wpcap.dll on the PC), the load of my module fails (of course). This means that users that want to use the simulator, but not my module, have a problem.

    Question
    Is there a possibility to defer the load of wpcap.dll? Either explicitly ( pcap_Load() ) or implicit at first library-call?

    Thank you
