Reading and writing to an embedded file

Hey guys, I've been thinking about this for a while, but I can't find any way on how to do this.

Basically what I want to do is have an embedded file in my program, that can be written to. This would be used to store a randomly generated password, that would be created and stored when the program was first run, and then read every time after.

I've looked at embedded resources, but it seems like you can only read from them. I've also looked at serialization, but everywhere I've looked suggests that files and such that are serializable are not able to be embedded into the application and modified. And lastly, I've looked at having a "settings" file, but that is stored in the application data, which isn't what I want.

If anyone has an idea on how to get this working, it would be appreciated.

How about storing it in the registry?

You could use Isolated Storage as well.

Or possibly use the ResourceWriter class.

Thanks for the responses guys, I'll check out each one and see if they work with what I want to do.
