Alessio,

There are some rare circumstances that appear to be a bug between the designer and the debugger, causing the method code to be replaced with object code when you go back to the designer from the debugger. If you see this when it first happens you can close the designer without saving changes shutdown VFP and start it back up and your form code should be intact. But if you've saved the form before noticing the code corruption you are out of luck and will have to recover the form from a backup or from a source control system.

>Just Yesterday and it was the secon time it happened , when I tried to save my last modified form I got the error "the file is not open" or somthing like that. I could do anything but break my VFP session and whe I enter it again I found my form corrupted. In most of code put in the various objects and method I found unreadble charachters, like piece of file sct came into the scx file.
>How could it happened ?
