hello,

i want to know what commands for doing the following in VB:
1. check the device is existing or ready
(e.g. i want to write a file to drive A so i will check the drive is ready first)
2. check the file is existing
3. rounding
( i read the ROUND command on the book, but i cannot use it in VB and cannot find it in the help)

Thanks

Regards

Diana
