• Is it possible to have a cell in table1 "point to" a cell in table2?

  - by Lewray

  I have a hierarchical structure in a database driven software application. Each row in parentTable 'owns' a number of rows in childTable. If the childTable does not have a value set in columnA then it should return the value specified in the appropriate row of parentTable columnB. Is it possible to implement a pointer or cell reference somehow so that I do not have to copy values from parent to child. (A change in parent could result in a large number of changes in child). If this is not possible, could anyone suggest a different approach?

• How to restrict deletion of a folder on NTFS share, but still allow modify access within folder

  - by thinkdreams

  I am setting up a set of scan folders from a scanning copier device, and would like to know the best way to protect the folders (for each department) from moving or deletion, but yet still allow access for the users to modify (i.e. create/add/delete) the scanned files within the folder. Structure is: Share Name Departmental Folder User files The writing of the files initially is taken care of by a service account which has full control. We'd just like to ensure the users cannot accidentally delete the folder (which has already happened) containing all the files, etc. This is for a Windows 2003 server, NTFS permissions. Suggestions would be most appreciated.

• Is there a "pattern" or a group that defines *rc files in *nix environments?

  - by Somebody still uses you MS-DOS

  I'm starting to use command line a little more, and I see there are a lot of ways to configure some config files in my $HOME. This is good, since you can customize it the way you really like. Unfortunately, for begginners, having too many options is a little confusing. For example, I created .bash_alias for some alias I'm using. I didn't even know this option existed, I'm used to simply edit .bashrc. Do exist a pattern, a "good practice", envisioning flexibility and modularity in terms of rc files structure? Do exist a standardization group for this, or every body just creates it's own configuration setup?

• Outlook '10 hangs often, IMAP sync

  - by user23150

  We have 3 employees using IMAP to sync with their Desktop and Android Phones. Two are using 70% of their accounts storage, another is using 80%. They all have similar counts on folder structure, etc. The employee with the 80% storage is constantly having Outlook freeze on them for up to 5 minutes at a time. I realize this is Outlook connecting and doing activity on the server, but no one else has this problem. In fact, one user with the 70% storage used uses a very slow laptop, and doesn't have freezing issues. The network is the same, the settings are the same - at a loss how to proceed? Obviously "Outlook is a crummy IMAP client" doesn't help management...

• Information about a file or directory

  - by Tim

  In Linux, the information about a file or directory is stored in its inode. I was wondering what is the data structure for information about a file or directory in Windows 7? How to get the information about a file or directory in Linux and in Windows 7, in terminal and command line window? Is the owner of a file or directory always its creator? Will it be able to change? Is there a creation timestamp for a file in Linux and in Windows 7? How to get it? Thanks and regards!

• How to show images in outline view in word 2010?

  - by Zonder

  I use a lot word with in outline view. In that view it is not possible to see images (while it was possible in 2007). When I paste an image in structure view it automatically changes the view to Print Preview. Is this a limitation introduced in 2010? If not how to get rid of it? I tried to read all the options, but I didn't find a matching checkbox. NOTE FOR BOUNTY: I started a bounty because this problem is really annoying for me. Please read the existing answer(s) and comment(s) before answering. Thanks.

• Cannot delete folder - Content seems to be nested recursively

  - by RikuXan

  I cannot delete a folder located on my hard disk by any means. I don't quite know how it was created, all I know is, that it is a pretty deep structure of folders (too deep to delete it at once, since Windows restriction path name too long), but the problem in the end is, that I can't "pull out" the inner folders, because they don't seem to be folders anymore (Context menu lacks things like "Properties", "Cut", "Copy", "Delete" etc.) Here a picture of how a right click looks like on one of these "folders": As you can see, the current folder is in very deep, but that is not the problem, rather the one I left-clicked on. Has anyone any advice on how to get rid of these? I tried a chkdsk, said no errors. I also tried deleting those folder via a VMWare Ubuntu, to no success. I also tried a batch file from a volunteer at MS boards, that should automatically de-nest such folders, but I guess mine is a special case, since the tool only created more such folders.

• Viewing zip archive contents using 'less' on OS X.

  - by multihead

  I couldn't help but notice that the 'less' program on all of the recent distributions of Linux that I've used (Ubuntu and Gentoo in this case) allow me to view the contents of ZIP and TAR archives, while the install of 'less' that I have on OS X (and Solaris) instead produce a "foo.zip may be a binary file. See it anyway?", which proceeds to spit out the raw binary data instead of a nice file structure listing. Google has not produced much in the way of helpful results -- it's tricky to search for 'less' in this context. I downloaded and built the latest version from greenwoodsoftware.com, but even it refuses to show the contents of these archives. I didn't come across any related configure/build options either. Any ideas? Thanks!

• Ultimate way to use Picasa in a home network

  - by luisfarzati

  I've been trying a lot of approaches but still didn't find any effective solution. I want gigs of photos in a network drive (a IOMega Home Media Network Drive, plugged to my wifi router). I'd like to do 2 things: Do a Picasa import process of all the photos in the drive, making Picasa organize all the files in a year/month folder structure physically. Ideally, the import target directory should be the same network drive, otherwise I should move all the imported files in my local computer back to the drive myself. Share the Picasa database over the network, by uploading it to the network drive. Have me and other members of the family point our Picasas to the network database, and see the photos as well as make changes (tag faces, create logical albums, etc) into it. Is ANY possibility to accomplish this? Or should I be looking for another photo management app, and in that case do you know such one? Thank you!

• Sorting Files into Subfolders based on EXIF Date

  - by honestor

  I have a huge directory from a HDD recovery that contains 70000+ JPEG files. I tried playing around with some AppleScripts, that I found, but had no luck. I already installed EXIFtool, which might be useful for this task. The current directory structure is as follows: dir001 - file0001.jpg ... - file9999.jpg dir002 - file0001.jpg ... - file9999.jpg ... dir070 - file0001.jpg - ... - file9999.jpg The files mostly have EXIF Data, but sometimes there are Files without metadata. Now I hope to be able to sort and rename these files into folders based on the date: 1999 - 1999 01 31 - 1999_01_31_-_22_59_59.jpg 2000 - 2000 05 20 - 2000_05_20_-_21_59_59.jpg - 2000_05_20_-_22_59_59.jpg I figured Applescript/Automator might come in handy for this, however every other solution would be welcome, too!

• Why does IIS 7 return a 500 when I access an HTML page?

  - by Out Into Space

  IIS 7 returns a 500 server error when I request an HTML page with this structure: <html> <head> <title>Test Page</title> </head> <body> Some text </body> </html> It works just fine the first time I access it, but subsequent attempts cause the error. If I remove the HTML tags, the error doesn't occur: <body> Some text </body> It seems very odd that the presence of the HTML tag would cause it to blow up. Any ideas?

• Access to a network server without port forwarding

  - by SdevDavid

  I have a network with the following structure. The server in PC2 is simple socket server TCP in 8080 port. I need to access to PC2 from other external network by socket client. This socket client knows the public IP (85.xxx.xxx.x), the private IP (192.168.0.21) and the port. How I can access PC2 without port forwarding on the router? If possible, I would like to have a reference in any programming language of this case.

• Disaster - partitions lost, data seemingly alive, how to recover?

  - by a2h

  I've used TestDisk and it's written my old partition structure of a ~20GiB partition for Vista, ~25GiB partition for 7 (but it now shows up as unallocated) and a ~400GiB partition for documents. What it's meant to be is a 30GiB partition for 7, some unallocated space, and a ~400GiB partition for documents. So currently, I have access to all my documents, but not any of the programs I've installed on C:, or AppData, because my boot partition is now supposedly a 20GB vista partition. I've tried using my Windows 7 install disc's repair function, but that did nothing beyond wasting about 10 minutes of my time. I'm currently posting from an Ubuntu live CD. Any help?

• Data unaccessible from WHS drive

  - by Eakraly

  Hi all, I had a Windows Home server machine that crashed. Before doing anything I decided to get data out of it. So I took the hard drive and connected it to Windows7 pc. What I get is that I cannot access almost any file! I do see directory structure, I can open small files like .txt and .ini but bigger files like .iso and video - no go. Same goes for Ubuntu and OS X - I can see files and even copy them - but they are corrupted. Any ideas for what the problem is?

• Is there a way to create a copy-on-write copy of a directory?

  - by BCS

  I'm thinking of a situation where I would have something that creates a copy of a directory, tweaks a few files, and then does some processing on the result. This wold be done fairly often, maybe a few dozen times a day. (The exact use case is testing patch submissions; dupe the code, patch it, build/test/report/etc.) What I'm looking for could be done by creating a new directory structure and populating it with hard links from the origonal. However this only works if all the tools you use delete and recreate files rather than edit them in place. Is there a way to have the file system do copy-on-write for a file? Note: I'm aware that many FSs use COW at a block level (all updates are done via writes to new blocks) but this is not what I want.

• Access denied to EFS encrypted files after PC joins domain

  - by mjmarsh

  I'm experiencing strange behavior with Windows Encrypted File System: I have a machine that is in workgroup mode (not joined to a domain) I encrypt an entire directory structure on the machine (basically a folder and subfolders with data files for my application). My application writes and reads files from the encrypted file hierarchy as a local Windows user (let's call the account 'SecureUser'). This works fine I then join the PC to a domain (Let's call it 'TEST') Afterwards, processes running as the local 'SecureUser' account can't read the files it wrote originally when it was off the domain (What is also strange is that the files are listed as "read only" now and I cannot unset this flag via Windows Explorer or the command line, even though it looks like it succeeds) I then 'un-join' the PC from the domain and everything works again Is there something about changing domain membership on a PC that changes the behavior of EFS so that previously encrypted files cannot be read, even by the originating user? Thanks in advance

• Turning a running Linux system into a KVM instance on another machine

  - by Charles

  I have two physical machines that I wish to virtualize. I can not (physically) plug the hard drives from either machine into the new machine that will act as their VM host, so I think that copying the entire structure of the system over using dd is out of the question. How can I best go about migrating these machines from their hardware to the KVM environment? I've set up empty, unformatted LVM logical volumes to host their filesystems, with the understanding that giving the VMs a real partition to work with achieves higher performance than sticking an image on the filesystem. Would I be better off creating new OS installs and rsyncing the differences over? FWIW, the two machines to be VM'd are running CentOS 5, and the host machine is running Ubuntu Server 10.04 for no particularly important reason. I doubt this matters too much, as it's still going to be KVM and libvert that matter.

• Regex working in RedHat is not giving any result in Ubuntu

  - by Supratik

  My goal is to match specific files from specific sub directories. I have the following folder structure `-- data |-- a |-- a.txt |-- b |-- b.txt |-- c |-- c.txt |-- d |-- d.txt |-- e |-- e.txt |-- org-1 | |-- a.org | |-- b.org | |-- org.txt | |-- user-0 | | |-- a.txt | | |-- b.txt I am trying to list the files only inside the data directory. I am able to get the correct result using the following command in RHEL find ./testdir/ -iwholename "*/data/[!/].txt" a.txt b.txt c.txt d.txt e.txt If I run the same command in Ubuntu it is not working. Can anyone please tell me why it is not working in Ubuntu ?

• Our company has 100,000s+ photos, how to store and browse/find these efficiently?

  - by tobefound

  We currently store our photos in a structure like this: folder\1\10000 - 19999.JPG|ORF|TIF (10 000 files) folder\2\20000 - 29999.JPG|ORF|TIF (10 000 files) etc... They are stored on 4 different 2TB D-link NASes attached and shared on our office network (\\nas1, \\nas2, and so on...) Problems: 1) When a client (Windows only, Vista and 7) wishes to browse the let's say \\nas1\folder\1\ folder, performance is quite poor. A problem. List takes a long time to generate in explorer window. Even with icons turned off. 2) Initial access to the NAS itself is sometimes slow. Problem. SAN disks too expensive for us. Even with iSCSI interface/switch technology. I've read a lot of tech pages saying that storing 100 000+ files in one single folder shouldn't be a problem. But we don't dare go there now that we experience problems on a 10K level. All input greatly appreciated, /T

• Everything You Ever Wanted to Know about Mod_Rewrite Rules but Were Afraid to Ask?

  - by Kyle Brandt

  How can I become an expert at writing mod_rewrite rules? What is the fundamental format and structure of mod_rewrite rules? What form/flavor of regular expressions do I need to have a solid grasp of? What are the most common mistakes/pitfalls when writing rewrite rules? What is a good method for testing and verifying mod_rewrite rules? Are there SEO or performance implications of mod_rewrite rules I should be aware of? Are there common situations where mod_rewrite might seem like the right tool for the job but isn't? What are some common examples?
