About copyfile: checking results

[Marco Turco]

Hi,
I use in my app (FWH 8.05) the function CopyFile (<orig.file>,<dest.file>,.f.) to make a backup of some archive files.

The problem is that I have a customer where some files are (randomly) not copied. I cheked that copyfile return (.f.) on those files so an error occurred.

I would like have an extended error code (like ferror() to be clear) in order to know the origin of this problem. Is it possibile to make this using copyfile or is there any other copy function with an extended error code manager that can I use ?

Thanks.

Marco,

Use GetLastError()

I tracked the COPYFILE function errors using GetLastError()
and an 1006 error appairs randomly copying files from an hard disk to a pen drive.

This is the Microsoft error code:
---
ERROR_FILE_INVALID
1006
0x3EE
The volume for a file has been externally altered so that the opened file is no longer valid.
---

Is there anyone that already had this error copying data on a pen drive ?
Any ideas ?

Thanks.

I use CopyFile() intensively to copy from hard disk to USB devices and never noticed any problems. This is the CopyFile() definition I'm using:

Code: Select all  Expand view

DLL32 FUNCTION COPYFILE( cExistingFileName AS LPSTR, cNewFileName AS LPSTR, lFailIfExists AS LONG ) AS BOOL;
      PASCAL FROM "CopyFileA" LIB "kernel32.dll"

Hi Enrico, thanks for your reply.

I am using the standard copyfile provided from FWH and the DLL32 code is the same.

I think it could be an OS/Hardware issue due to the fact that I also have a lot of customers that never reported me this problem but I would like give a suggest to this customer in order to solve/bypass this problem.

Sorry, I can't imagine why a simple API would GPF...

Enrico,

It seems as there is no a GPF but an error returned code.

Marco, maybe you could try it for n times, in case that another try is able to do it.

Ops!

Yes,
in the meantime I asked the customer to format this pen drive
and if the problem still remains I will try the copyfile 3 times before to stop the routine and display the error code.

Thanks to all.

Marco,

You might also suggest that your customer try another pen drive--the one they are using could be defective.

Marco,

I had a problem with USB drive on my VISTA PC, too.

What is ISREADY( cDrive ) returning?
Here it errored out with this error screen. As a solution I deinstalled all the USB ports and drivers and installed the USB ports again.

Otto,

Have you located what exact function call is generating the GPF ? thanks,

Hello Antonio,
I am sorry but I don't have done more tests as I reported in the thread.
Now as I have reinstalled the USB ports I can't reproduce the error.

Otto
