Hi Arnon,
Thanks for your reply,

I also not sure what happened to my class, just a mistyped code, I choose fix on debugger and boom !! it disappeared......

I think it's no way to call the class by use as a table, since I unerase it, (I don't know VFP just erase the class), and when I call it as a table, it's only a platform and uniqueId field with an unreadable data, I think it's ruined, and the bad news is I have to re-create the class...

But anyway, many many thanks for your reply.

Regards,
