How can I tell when my file is done copying?

[Terry Olsen]

Using the following code to copy a file from a local pc to a remote
server across a 128K line:

File.Copy(src, dst, True)

If File.LastWriteDate(src) = File.LastWriteDate(dst) Then
Msgbox("Upload Verified.")
Else
Msgbox("Upload Failed.")
End If

It always comes back failed. But if I wait a few moments and check it
again, it'll come back Verified.

I guess the File.Copy is exiting before the copy is complete? So how
would I be able to verify the copy has fully completed before checking
the LastWriteDate?

if File.Copy doesn't throw, then you can fairly safely assume it was copied.

in addition to Robin

try
File.Copy(src, dst, True)
Msgbox("Upload Verified.")
catch ex as exception
Msgbox("Upload Failed.")
end try

If File.LastWriteDate(src) = File.LastWriteDate(dst) Then

But if I wait a few moments and check it again

If this using any third party connectivity stuff, e.g. SAMBA to a Unix
box? Could the file information be being cached?

To be honest, though, so long as .Copy doesn't throw an Exception,
you can pretty much assume that the file's been correctly delivered.
