Using callbacks with ReadFileEx
Hi all,
First, I just realized I''ll need to go back and fix some of the
prototype declarations for windows-pr. The callback parameters will now
need to be set to ''K''. ReadFileEx is one example of this. For purposes
of my question, let''s assume ReadFileEx has been declared like so:
API.new(''ReadFileEx'', ''LPLPK'',

Playing with ReadFileScatter()
Hi all,
Looking at the IO.readlines source in io.c, it looks to me like they
grab 8k chunks, split on the input record separator, and buffer accordingly.
Since it looks like ReadFileScatter() does some of that work
automatically (in page file sized chunks), I thought I''d give it a try.
Here''s what I''ve got, but it doesn''t work. I have an incorrect parameter

Calling CreateFile on an instance of File - possible?
Hi all,
I''m going over win32-file this weekend. I''m creating instance methods for
setting (or unsetting) the various file attributes. So, you can do
something like:
f = File.open("foo.txt")
f.archive = true
f.hidden = true
f.close
This works for the basic attributes, but it requires extra work for others.
Specifically, I am having trouble trying to set the

sync always, strict sync, cache question
Hello,
I've been using samba to share folders for a number of years now.
thankyou very much to the samba team.
Now I'm posed with some questions.
I have a couple of servers hosting desktops for thinclient users.
Until now I have been mounting /home with NFS on these servers.
Recently we have upgraded the whole system and have run into write
performance issues with the NFS server.

Running SQL over SAMBA?
Hi All,
Does anyone run SQL and/or exchange on SAMBA server share?
Are there any special considerations to take? would you be kind enough
to share your experience doing it?
Any special smb.conf configuration is required?
is there any performance issue or functional limitations supporting it?
I am just wondering since Microsoft encourages block level access over
share/file level access.

Possible to access a USB volume by name in windows
On the Mac it's pretty easy to get to a USB drive by name. For example the
following command works if you have a USB drive named "MYUSB"
setwd('/Volumes/MYUSB')
Is there a way to do the same thing in Windows (without knowing the drive
letter)?
Thanks!

CreateFile for EXE images vs other files
This question isn't directly Samba related, but Samba has helped me figure out part of the problem. When I CreateFile on an existing file like so:
CreateFile(FileName, GENERIC_READ, FILE_SHARE_READ | FILE_SHARE_DELETE, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);
Samba shows that I have the file opened with this type of lock

USB passthrough of all USB-slots to guest
Hi,
how can I define passthrough of all USB-slots to a guest with libvirt?
With qemu it's very easy:
# kvm -usb -usbdevice host:0.* -usbdevice host:1.* -usbdevice host:2.* -usbdevice host:3.* ...
This configuration of the VM gets *all* 4 USB-Slots. Every time somewhat USB-device
is plugged in the VM gets it.
virt-install manpage offers:
--host-device 001.003

nread and nwrite optimizations
Hi all,
So far, so good. Things seem to work just fine and, in the case of
nread, I am getting incredible performance. I can''t tell if this is due
to some kind of caching, however.
Anyway, there a couple of things I want to work out yet. The first is
File#nread and Really Big Files. I created a 500 mb text file and
sucked it into memory using Ruby''s File#read method just

[PATCH] move CreateFile() function from libFLAC
This patch renames flac_internal_CreateFile_utf8() function to
grabbag__CreateFile_utf8() and
moves it from /src/libFLAC/windows_unicode_filenames.c into
src/share/grabbag/file.c
This function is not used by libFLAC anyway.
After this, it should be possible to compile libFLAC as UWP.
In the old code there were 3 different #if conditionals around the
code that uses CreateFile_utf8():
1) #ifdef

Setting Group owner of files on USB drive
I just got a 8Gb flash drive and went to copy a bunch of files onto it.
I wanted to perserve everything, so I just took my archiving rsync
command and altered it to go to localhost:/media/RALLY2/ (name of flash
drive). I am getting errors with changing the group owner. Huh?
So I try to just use mkdir to create a directory on the flash drive.
The directory has a group of root ???

win32-dir, unicode
Hi,
I''ve got a preliminary version of the pure Ruby version of win32-dir in
CVS. However, I was hoping to work out the Unicode issue. Run this:
from = "C:\\test"
to = "?????"
Dir.mkdir(from) unless File.exists?(from)
Dir.create_junction(to, from)
It works, but my explorer (and dos) window shows the name garbled. I
don''t think it''s a font

About Parallel Port Driver
Hi all,
I have a .sys driver for parallel port communication.
But it seems wine didn't support loading the driver.
My windows program has to be configured as XP version.
And directly accessing to parallel port is not allowed on the XP host,
therefore _outp and _inp are useless. Is there any solution to this problem?
Best Regards,

[Newbie] How to get IE5.0 run
I try to get IE 5.0 run under wine. All I understood is that I have to
use a native installed IE, which I copied FROM Win98SE under VMWare to my

native windows/system directory, too.
This didn't work, even when I'm starting with this switches: wine -dll
