Adding resource to a file!

[CSharper]

Just curious, When you are in IDE, you are able to add a resource to
the project through resource tab. Later this resource can be accessed
using the resource manager. One good thing about this approach is
that, the resource file is build into the exe and using resource
manager you can later get already added resource file back.
Now is it possible to do that through programatically? I want to add a
resource to the default resource (if I use resource writer then I need
to explicitly specify the resource file and that resource file need to
be distributed along with the exe) during execution on the fly, is it
possible?

Thanks.
