vb.net how to change values in embedded "My.Resource" files

Question

First thing I want to do:

I would like to know if an embedded resource file can be changed? If I had a test.htm in the resource area and in side that file i had the word "YourVariable", When i load form1 (Run program) it would change "YourVariable" that is in resource test.htm "my.resource.test" to "Hello World". I be using vb code to do this.

Last thing I want to do:

I know how to copy my.resource file to local hard drive and change the "YourVariable", but I can't copy it back in to my program my.resource file, with the updates.

In the first thing to do can this be done, edit resource file(s) in your program?
