I solved my problem with this "LoadResourceFromUri" fonction defined below. I've done and published a project at GitHub with a tool to load any module (dll) and display its resources. Could also get info on uri.
About the offset of 4 while converting byteArray to stream, I used Microsoft code because otherwise (without offset), it just don't work as expected.
