Sounds like you might want to look for some file recovery software and see if you can recover them that way. As for the EXE, once you recover the resouce files, that should be recompilabe, but I am sure you know that.
I have had a similar experience, and, unfortunately, had to start from scratch. After that I started saving templates of my forms so that if I lost one or two, I could go back a get a template and have the form up and running again in no time. Another thing I do, is I have two hard drives, and back up projects on the other hard drive. So far I am pretty benighted when it comes to using a source control program though!
