Hi,
In my infinite wisdom msg = (_GetMsgName)( void ); should be msg = (_GetMsgName)( );
But now when i run wireshark, it crashes. Is there a way to tell why it is crashing? I'm not sure what the cause is.
Thanks,
Greg

234 is the line where appears the problem.
Look at this line.
Perhaps you can find more help on forums about windows and C/C++.

I'm currently using LoadLibrary() and i have just started trying to use the dll. My dll will be using 2 other .lib's. Is it possible to create a variable in the dll and have functions that can be used by the dissector plugin to set it and manipulate it without having direct access to it? I have tried to do so since it is a class that i am trying to manipulate, which you cant do in c. The dll is written in c++. Also, i'm having a bit of trouble using the functions in my dissector. Here is some sample.
