Making code "CAS-safe" and "environment safe"

I ask as some stuff I am writing will be demo'd from another machine.

Thanks

I think these two MSDN articles should provide you the information you need about accessing resources in an assembly:

Resources in Applications

Packaging and Deploying Resources
