Sam,
Thanks for your good help intentions.
I somehow (not sure) managed to restore the files, but I'm not sure what I did.
I simply collected the files I believed should be in the project and made sure they all are in the right folder with the correct namespace, and the most important (i believe) was getting rid of repetitions.
I find the VS (I use Express) to be extremely (dangerously) sensitive to file handling and lacking good automatic file backup (I used to work with Borland Builder where each build saved full backup of previous builds).
I would nevertheless appreciate any good guidelines that will help me prevent such issues in the future.
Sam
