VB.net bugs....

Hello,
i build a project in vb.net with the wrapper.
IR transmission works well but i get an unmanaged error when the IR learning completes (100%).
Here is a zip of my project:
http://snort.free.fr/usbuirt/testusbuirt1.zip
Question: as i have the wrapper.net source code, is there a way to include it in my project and debug it ?
thanks in advance
