File is busy

I need to copy the file (OutboxLog.txt produced by Fax service) right after
it was updated. I'm using:
System.IO.File.Copy(strSource, strDestination, True) to do that, but if the
source file is busy (was not closed yet after update) the copy process
fails.
I tried to insert a loop:
For lngAttempt = 0 To 100000

Application.DoEvents()

Next

It works, but I don't like this approach. I would prefer something like:
Do While IsBusy = True
IsBusy = (some code which returns the status of the file)
Loop

Unfortunately I do not know what do I have to put on the right in this
expression.
Any idea please

Thank you

Al

I have used:

Do
Try
file.copy(source,dest)
Exit Do
Catch
End Try
Loop

As many times as this question is ask on the newsgroups, you'd think M'soft
would get the message and implement a property or method for FileInfo to get
the file status like busy, opened for readonly, opened for write, etc. by
another applicaiton.
