• Would this prevent the row from being read during the transaction?

  - by acidzombie24

  I remember an example where reads in a transaction then writing back the data is not safe because another transaction may read/write to it in the time between. So i would like to check the date and prevent the row from being modified or read until my transaction is finish. Would this do the trick? and are there any sql variants that this will not work on? update tbl set id=id where date>expire_date and id=@id Note: dateexpire_date happens to be my condition. It could be anything. Would this prevent other transaction from reading the row until i commit or rollback?

• How do I can linux flock command to prevent another root process deleting a file?

  - by Danmaxis

  Hello there, I would like to prevent one of my root process from deleting a certaing file. So I came across the flock command, it seems to fit my need, but I didnt get its sintax. If I only indicate a shared lock, it doesnt work: flock -s "./file.xml" If I add a timeout parameter, it still doesnt work flock -s -w5 "./file.xml" It seems that way, it fits in flock [-sxun][-w #] fd# way. (What is this fd# parameter?) So, I tried the flock [-sxon][-w #] file [-c] command Using flock -s -w5 "./file.xml" -c "tail -3 ./file.xml" and it worked, tail command at ./file.xml was executed. But I would like to know, does the lock end after the command or does it last 5 seconds after the end of the command execution? My main question is, how can I prevent another root process deleting a file in linux?

• Can I prevent a user from using windows task manager to end a process?

  - by Russ

  I have a c# 4.0 application that I hear grumblings and rumors about problems with. Now, this application has a global unhandled exception handler that reports back to me with errors. I also know that it works because SOME people fill it in, and submit it. It seems though; that a large number of people do NOT fill it in, but instead, use the Windows Taskmanager to end the process. Is it possible to prevent a user from using the Windows Taskmanager to end a specific process? My goal would be that if the application crashes, the form that the user is presented with prevents the process from being ended. I'll also accept steps that would prevent the Windows Taskmanager from being launched. I know I have seen some processes come up with an "Access Denied" prompt when I try to kill it in TaskManager, however I suspect that the windows team has made this very difficult, if not impossible to achieve.

• When designing an event, is it a good idea to prevent listeners from being added twice?

  - by Matt

  I am creating an event-based API where a user can subscribe to an event by adding listener objects (as is common in Java or C#). When the event is raised, all subscribed listeners are invoked with the event information. I initially decided to prevent adding an event listener more than once. If a listener is added that already exists in the listener collection, it is not added again. However, after thinking about it some more, it doesn't seem that most event-based structures actually prevent this. Was my initial instinct wrong? I'm not sure which way to go here. I guess I thought that preventing addition of an existing listener would help to avoid a common programming error. Then again, it could also hide a bug that would lead to code being run multiple times when it shouldn't.

• What is the best way to prevent a webpage coded completely in HTML (no PHP or any server side langua

  - by racl101

  I thought by placing these two lines that it would prevent the page from being cached but this is not the case between the head tags: <meta http-equiv="pragma" content="no-cache" /> <meta http-equiv="cache-control" content="no-cache" /> As already mentioned this is on server that doesn't support PHP (or any server side language, well, that's not true, it has cgi-bin folder that supports perl scripts but I don't know perl and have no time to engage in it.) What else could I do to prevent the page from caching? It caches on Firefox and IE (and not so much in Chrome or Safari.)

• How to prevent robots from automatically filling up a form?

  - by sombe

  I'm trying to come up with a good enough anti-spamming mechanism to prevent automatically generated input. I've read that techniques like captcha, 1+1=? stuff work well, but they also present an extra step impeding the free quick use of the application. (I'm not looking for anything like that please). I've tried setting some hidden fields in all of my forms, with display: none; However, I'm almost certain a robot (which is essentially a program) can be configured to trace that form field id and simply not fill it. Do you implement/know of a good anti automatic-form-filling-robots method? Is there something that can be done seamlessly with HTML AND/OR server side processing, and be (almost) foolproof? (and please no JS, one could simply disable it, and there goes my anti-spam method). Btw I'm trying not to rely on sessions for this (like, counting how many times a button is clicked to prevent overloads).

• I am not able to delete a corrupt NTFS partition on my pen drive. How can I force its deletion?

  - by yesuraj

  I formatted my 16GB pen drive with the NTFS file system in windows vista. After that I started copying some files. However, only a few files were copied to the pen drive before the copy operation hung. So I cancelled the copy operation. Now I am unable to use the pen drive. I DON'T REALLY NEED ANY FILES THAT I COPIED TO THE PENDRIVE. I JUST WANT TO USE THE PENDRIVE AGAIN. I have tried using Ubuntu to format the pen drive. But when i use fdisk to delete the partition, it looks like it is working fine but in fact it does not delete the partition. Also I am unable to format it with any other file system. When I tried to use gparted, it throws the following error: Error mounting: mount exited with exit code 14: The disk contains an unclean file system(0,0). The file system wasn't safely closed on window. Fixing ntfs_attr_pread_i:ntfs_pread failed: Input/output error Failed to read NTFS$Bitmap:Input/output error NTFS is either inconsistent, or there is a hardware fault, or it's a softRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows then reboot into windows twice. The usage of the /f parameter is very important!. If the device is a SoftRAID/FakeRAID then first activate it and mount a different device under the /dev/mapper directory, (e.g. /dev/mapper/nvidia_eahaabcc1). Please see the dmraid documentation for more details When I searched the Internet I found help on how to recover. But I don’t want to recover, I want to format it again. When I pressed w after deleting the partition, it took more time than previously. After that i removed the pen drive and re-inserted, but the partition I had deleted was still present. If I simply type the command fdisk /dev/sdb without removing the pen drive after the partition is deleted, then it returns the error message Unable to open /dev/sdb. Here are the steps that I followed: root@yesuraj-ubuntu:~# fdisk /dev/sdb Command (m for help): d Selected partition 1 Command (m for help): w The partition table has been altered!

• How to prevent any files from being copied onto the Desktop?

  - by Kaushik Gopal

  Gentlepeeps, Is there any solution to prevent copying of files onto the desktop? My folks and i currently have one super-common-comp in our place. And when all of the laptops are busy, we tend to do some quick surfing on this comp. I prefer to keep things freakishly organized in this comp and one thing i hate is having those off-shoot irritating forwarded downloads on my desktop. Is there some way to restrict files from being copied onto the desktop? I tried making the administrator user's desktop folder as read-only :P . That doesn't solve the problem. Any other ideas/software/solutions? cheers.

• How does a PDF prevent itself from being printed?

  - by Steven

  I have a PDF for my camera's manual, and Adobe Reader won't let me print it (the print option is grayed out). SumatraPDF also does the same thing (it even says print denied). How does the PDF prevent itself from being printed? It seems that if the program can display it on the screen, then it can also print it. Maybe Adobe Reader respects the PDF not printing, but surely an open source PDF reader wouldn't be so restrictive. So is there something more to this than merely the PDF reader software respecting the PDF's request to not be able to be printed?

• I would like to prevent these entries from being added to the eventlog.

  - by David Smith

  Our client's application EventLog is getting filled up with warnings due to a bug in the Microsoft SQL Server report viewer control, http://support.microsoft.com/kb/973219. They have thousands of users running reports so this is making their eventlog hard to use and they want them removed on a frequent basis. I tried using PowerShell to remove the events, but that does not seem possible. Is there a way to prevent these entries from being written to the event log in the first place? I'm thinking I would like to filter out events where event source="ASP.NET 2.0.50727.0", eventId ="1309" and Message contains "Reserved.ReportViewerWebControl.axd"

• How do I prevent IIS 8 from stopping idle ASP.NET applications?

  - by Lambo Jayapalan

  I have an asp.net application running on Windows 2012 in IIS 8 that has a very time consuming application start process (essentially the code running in the Application_Start() event can take up to 2 minutes). Thus I'd like to minimize the number of times the application is started so that the user can avoid a long wait. I've enabled Preload in the application settings, and I've set the Start Mode to AlwaysRunning in the application pool. Yet the application still ends after not being used for a while, resulting in a very long time for the first visit to the website after the application shuts down. Does anyone have any ideas on how I can prevent this? Thanks

• How to prevent Mac OS X creating .DS_Store files on non Mac (HFS) Volumes?

  - by sudo petruza

  Is there a way to prevent Mac OS X creating .DS_Store and other hidden meta-files on foreign volumes like NTFS and FAT? I share an NTFS partition with data like Thunderird & Firefox's profiles and apache's DocumentRoot, between Mac OS X and Windows, which is very handy. I don't mind if Mac OS X is not capable of indexing or otherwise doing the neat things those metafiles are for. Note: It's not shared over a network, both operating systems and the shared partition coexist on the same disk, on the same machine.

• SQL Server: Is it possible to prevent SQL Agent from failing a step on error?

  - by franklinkj

  I have a stored procedure that runs custom backups for around 60 SQL servers (mixes 2000 through 2008R2). Occasionally, due to issues outside of my control (backup device inaccessible, network error, etc.) an individual backup on one or two databases will fail. This causes this entire step to fail, which means any subsequent backup commands are not executed and half of the databases on a given server may not be backed up. On the 2005+ boxes I am using TRY/CATCH blocks to manage these problems and continue backing up the remaining databases. On a 2000 server however, for example, I have no way to prevent this error from failing the entire step: Msg 3201, Level 16, State 1, Line 1 Cannot open backup device 'db-diff(\PATH\DB-DIFF-03-16-2010.DIF)'. Operating system error 5(Access is denied.). Msg 3013, Level 16, State 1, Line 1 BACKUP DATABASE is terminating abnormally. I am simply asking if anything like this is possible in SQL 2000 or if I need to go in a completely different direction.

• How can I prevent the warning No xauth data; using fake authentication data for X11 forwarding?

  - by Sorin Sbarnea

  Every time I initiate an ssh connection from my Mac to a Linux (Debian) I do get this warning: No xauth data; using fake authentication data for X11 forwarding. This also happens for tools that are using ssh, like git or mercurial. I just want to make a local change to my system in order to prevent this from appearing. Note: I do have X11 server (XQuartz 2.7.3 (xorg-server 1.12.4)) on my Mac OS X (10.8.1) and it is working properly, I can successfully start clock locally or remotely.

• How to prevent a URL in an email I send from being auto-linked by the recipient's email client?

  - by gilly3

  When I type a URL into an email in Outlook, it automatically converts it to a hyperlink. I can, of course, remove the hyperlink from the context menu: But, then when the email is received and when I view it in my Sent Items folder, the urls are again converted to hyperlinks. How can I prevent this? Embedded images are no good because the URL must be copy and pasteable (among numerous other reasons that this approach is not great). And it must retain the formatting applied when I send it. This answer on stackoverflow shows a good trick for preventing auto linked urls when sending an email programmatically, but I'm looking for a way to do this from the UI. Perhaps there a way to edit the HTML of the message before it is sent? If not, I guess I'm off to write an Outlook Add-in.

• SQL Server 2000 need to prevent logons whilst performing a backup for a side by side migration

  - by pigeon

  I'm looking for a way to prevent logons from occurring in order to take a full backup of a Database to migrate from its current SQL Server 2000 instance to a new SQL 2005 instance. A friend of mine suggested running a script which would put the DB into a rollback state. Not being a DBA my DDL is very poor and running a script that I don't understand may not be the best idea. One option which might be easier is to simply detach and copy, to the new server. Any suggestions would be greatly appreciated.

• How can I prevent Ask.com Toolbar from being installed every time Java is updated?

  - by abstrask

  As many are painfully aware of, Oracle continues to not only bundle the Java installation with the useless Internet browser toolbar from Ask.com, but also enable its installation by default. In addition to the toolbar, Ask also replaces your favourite search engine in your browser with Ask. Furthermore, the Java installation goes as far as to actually recommend installing this useless junk, meaning that any non IT-savvy person is more than likely to leave it checked and install it (after all, it was enabled by default and the friendly Java installer did recommend it, right?). To add insult to injury, even if you remove the Ask Toolbar, you can be sure to see it again soon, when the next Java update hits you (which seem to happen quite often lately, due to loads of security fixes for Java, but that's another story). I'll duly remove the check-mark to install Ask Toolbar, whenever I update Java, but when supporting my family and friends, it's obvious they don't. How can I prevent the pesky Ask.com Toolbar from being installed in the first place?

• How to prevent stretching, blurring and pixelating of embedded logos in VirtualDub?

  - by NoCanDo

  Howdy, take a look at this please http://www.youtube.com/watch?v=te-HVN8y_QE&hd=1 . Notice the embedded "logo" in the upper left corner? How blurry and pixelated it is? This is the original image: http://i.imagehost.org/0148/movie_watermark.png ! The stretching, blurring, pixelating etc. most likely comes from resizing the original video from 1920x1200 to 1280x720 and encoding it with h.264. Can anyone tell me how I can prevent the blurring, unsharpening and pixelating and retain their original quality? How do I exclude the logo from the whole encoding process and just slap it there in its original format and form?

• Can I prevent Internet Explorer 8 from running scripts until the page is loaded?

  - by Tom W

  When trying to veiw a number of different websites in IE8, I get the following error message: HTML Parsing Error: Unable to modify the parent container element before the child element is closed (KB927917) On investigating the error message, it appears the script is trying to modify parts of the page before it is fully loaded. Is there a setting in IE8 I can change to prevent scripts from running until the page is fully loaded? EDIT: The sites in question used to work just fine, until I had to re-install IE8 for a seperate issue. Then they stopped working.

• How do I prevent internet access to a group of computers on my network?

  - by Kevin Boyd

  Well I have the following setup... Computer A , B and C are networked.... Computer A is connected to the internet, computer B and C are not setup for internet access currently but I guess its possible with some kind of setting they would eventually be able to access the internet and this is what I would like to prevent. In summary only A should have internet access while A and B and C should still be on intranet. Is this kind of config possible?, what kind of software or setup or tools would I need to achive this?

• Web site kills hard disk I/O, how to prevent?

  - by Taras Voynarovsky

  The situation: I have a server, on which we have 2-3 projects. Starting not long ago, the server started hanging up (We could not connect to it by ssh, and the connected clients had to wait 20 minutes for top to give results) Early today I managed to execute gstat while it was in this state and saw, that it stays on 100% on da0, da0s1 and da0s1f. I dont quite know what those ids meen, but I understand that some processes just kill the HD by bombing it down with requests. I ask of some propositions. I dont know how to find the culpit and can't prevent this. I have freebsd on server.

• How do I prevent 'net ads join' from doing DDNS update?

  - by genehack

  I'm using 'net ads join' to add Linux servers to an AD domain. The servers are multi-homed, with a public IP on eth1 and a non-routable private background network on eth0 (in the 172.20 space, used for netboots and installs and stuff -- no routing to the Internet on that network). When I 'net ads join', it appears that a DDNS entry is getting created for the 172.20 interface. How can I prevent this from happening? (FWIW, my powers at the AD level are very limited -- I can join servers and delete server records but that's about it...)

• Prevent the "System" process from locking my files in a shared folder.

  - by Kamarey

  I have an application that creates files to be processed by SQL bulk. The files are created in shared folder on another server and than taken from there by SQL. The problem that sometime SQL returns an error, that the file is locked by another process and can't be accessed. The process that locks these files is "System" process. Looks like it lock files because of they are in a shared folder, but not sure. The use of any software to unlock files manually is not an option, as all bulk process is automatic. The question is: Why the "System" process locks these files and is there a way to prevent this?

• How can I prevent JungleDisk/MacOS X (10.6) creating a local volume for a removed external drive?

  - by Rew

  Ok, here is situation: I use JungleDisk to sync an online folder on to a external drive connected to my Mac. If I right click Finder, click Go to Folder... then type /Volumes/ I see the drive linked here. Once I remove the external drive, an actual folder is created here in the name of the external drive, JungleDisk continues to copy files to this folder, rather than stop. Is this a feature of Mac OS X? Can I turn if off? After I re-connect my external drive, the link to the drive is appended with a 1 (so if I called the drive SpareDrive it becomes SpareDrive 1 as the newly created folder is called SpareDrive. I realise my explanation isn't very clear, but anyone understand this, and knows how to prevent it happening please let me know. PS: I have a low reputation as I don't use this often, I tend to use stackoverflow, but will check back here for answers.

• How can I prevent my computer from waking up accidentally?

  - by Ivo Flipse

  When I put my computer into sleep mode, it will wake up while I'm away from it. There's nothing near the computer that could move the mouse or accidentally press a button and I have no idea what might be causing it. I tried checking what woke it, apparently LASTWAKE only tells me that it has been in sleep mode, not what woke it up. I also couldn't find anything in my Power Options regarding Sleep that seems off. Poking around in the Event Viewer I notice the following: The Power-Troubleshooter event at the top notes the following: The system has returned from a low power state. Sleep Time: ?2012?-?10?-?27T11:31:53.408927000Z Wake Time: ?2012?-?10?-?27T12:25:51.887029300Z Wake Source: Unknown So does anyone have an idea to find out what might be causing it and how I can prevent my computer from randomly waking up?
