A good question about resource files.

Question

I have had a lot of trouble finding information on this topic and being unable to figure out the code myself I am hoping that someone can explain it once and for all. I would think this would be a more common problem.
 
I have an executable with a resource file in it. I want to update that resource file on the clients machine. How?
 
This is what I have found http://msdn.microsoft.com/en-us/library/ms648008(VS.85).aspx but obviously that is pretty confusing stuff. I have tried this but can't get it to work. I'm not sure if I am using the wrong variables or if it just can't be done in C# or what. I guess I am dumb but I have no idea how to accomplish this seemingly simple task.
What I am asking for is a no BS, easy to follow, very basic guide to updating (or creating) a file in a .exe's resource file.
