choose say floppy drive and it causes error "Device Unavailable" if no disketts are in the drive or no disks in the cd-rom
i want to know 2 things

2.let's not remove it ,how can i make a error myself ,if device is not
available and after the error we are back to proram not letting to quit ;)

Use the "ON ERROR" statement
for example

On Error goto NoDiskError

... more code here

NoDiskError:
MyDiskErrorform.show
