1. File copy problem
I have written a Windows app which backs up data
over a lan to a CD burner. This works fine, using
createDirectory() and copyFile() in Win32Lib.
The files are large (~50 megs), so it would be nice
to have a progress bar to show how far along the
job has gone.
Question: how to find out how much has been copied,
so I can set the progress bars? Do I need to start a
separate program to monitor this?
BTW: I tried using a Euphoria routine to copy the
files, but it's just too slow.

Irv

Hi Irv,
the short answer is that you need to use the API function called CopyFileEx
instead on the simple
copyFile() routine in win32lib. This API function uses a call-back routine, that
you write, that
enables you to update a progress bar or the like.
Let us know if you want any more help with that.

Some of the info I have found on CopyFileEx() states that
this routine is only available on NT, not Win 98 or 95.
Do you know if this is true? I don't want to spend time
trying to decipher those structures just to find out it
won't work anyway.
Thanks,
Irv

Header file winbase.h :
#if(_WIN32_WINNT >= 0x0400)
//
// Define possible return codes from the CopyFileEx callback routine

Thanks, Bernie.
You saved me a headache. If this were Linux, I would just
open a new program which would watch the output file and periodically
update a progressbar display with the current size. I don't know
if that's possible in Windows.
