Philippe

I sent you an e-mail with some screen shots but it appears the screen 
shots were too big.
So here is my outcome...maybe you will get the screenshots later.

I still get the same results.
I changed in the code where the ports file lives at to (c:/ports.txt). 
My ports.txt file is at the root of C:.
I rebuilt the code.
Deployed the .dll's files to the plugin directory of several machines 
running different versions of wireshrak
and I still get:

**"Couldn't load module", The specified module could not be found.**

I build your code using VS 2005.

Any Thoughts...??

Are you able to run my plugin on any machine or just a development 
machine..?
The goal of this plugin is to have people download the helen.dll file 
place it in their plugin directory and have it work.

Having them download wireshark and build it to get my plugin to run is 
probably too much effort
I can get this to work on Linux with no problems. They download the 
helen.so file place it in the plugin directory and everything works fine.

Thanks again for all your help.

Brian
