copy overhead it is the second problem, the fact is that: VFP files == insecurity
Doesn't exist any way of copying into a file with exclusive access a Blob/memo
and to execute it with a DO command; a small interval time exists where the file is free;
a good hacker can
- capture the API FCLOSE event
- to put to sleep VFP,
- to modify it ;
to wake up again VFP that performs confident a different thing.
To do this inside the memory of the VFP process it is very more difficulty
because it needs to hypnotize the OS Kernel.
