  • IIS wont run a BAT File

    - by Ye Ol Developer
    The problem we have run into is as follows. We have an ASP.NET WebService which runs under IIS7. The code in the WebService works 100%, however when the WebService tries to run a .BAT file, nothing happens. Nothing at all, the code doesn't crash, the server doesn't warn us about anything, nothing at all. We have tried setting the User Permissions, we have attempted difference ways of running the BAT, we have tried playing around with the registry, cmd.exe has full rights as well. We are now quite stumped as of what to do, any help would be appreciated.

  • bat file to disable ethernet adaptor and then reenable it after windows log in

    - by jaslr
    When I log into Windows 7 I need to wait 10 seconds and then disable the Local Area Connection (ethernet adaptor) and then reenable it. I have looked through the suggested answer: Enable/disable wireless interface in a bat file but that seems irrelevant as it just toggles the current state. From what I can tell I need to include: netsh interface set interface "Local Area Connection" DISABLED netsh interface set interface "Local Area Connection" ENABLED but I'm unsure of the wait time or how I can have this start after Windows has successfully logged in. What's the best approach here?

  • Recover deleted files on windows 2008 file server

    - by aniga
    We have recently been hit by a weird virus which made all files and folders a system files/folders and also it hid all files and folders par some weird ones it created including: ..exe porn.exe secret.exe password.exe etc We have managed to restore the files with attrib command to unhide and unmark them as system files however we have noticed that we are missing some 4 to 5 folders of which (based on my luck) 2 of them are the two most important client we have. I am not sure if these files were deleted by the worm/virus or by my colleagues who are not owning up to them but the files are now gone. Worst of all, we do not have any backup what so ever (Yes I know, we should not have done that but it is a lesson learned and since last night we have created two forms of backup systems one to external device and one on the cloud, but I doubt any of that will help us now) We have 1 Windows 2008 File server and 4 client computers based on Windows 2007. I would be grateful if anyone can help us on how we can recover from this disaster which could potentially put us out of business.

  • Seeking to a line in a file in g++

    - by Phenom
    Is there a way that I can seek to a certain line in a file to read or write data? Let's say I want to write some data starting on the 10th line in a text file. There might be some data already in the first few lines, or the file could even be empty. Is there a way I can seek directly to the line I want without having to worry about what's already in the file?

  • How can I run a batch file silently?

    - by Mike Pateras
    I have a batch file with some commands that I need to run with my installer, but I'd rather a console not appear (in Windows). I'm executing the batch file from a WiX installer, via a custom action. I tried adding an @ECHO OFF to the top of the file, but that didn't seem to do anything. Is there a way that I can run this batch file silently?

  • Check directory for files, retrieve first file

    - by Lowgain
    I'm writing a small ruby daemon that I am hoping will do the following: Check if a specific directory has files (in this case, .yml files) If so, take the first file (numerically sorted preferrably), and parse into a hash Do a 'yield', with this hash as the argument What I have right now is like: loop do get_next_in_queue { |s| THINGS } end def get_next_in_queue queue_dir = Dir[File.dirname(__FILE__)+'/../queue'] info = YAML::load_file(queue_dir[0]) #not sure if this works or not yield info end I'd like to make the yield conditional if possible, so it only happens if a file is actually found. Thanks!

  • file sharing over external and internal networks

    - by pradvk
    Dear friends, Please tell me whether it is possible for someone on the external network to see the network folder shares of an internal LAN network in DHCP (192.168.x.x) through a Comp-A on an external network in DHCP (123.123.x.x) both networks are on different subnets but Comp-A has access to both networks and can see all the shared drives of both the internal and external networks using firewall is not an option because file sharing is required everywhere. care is taken from viruses/trojans... remote desktop etc is disabled on Comp-A Please let me know. Thanks and Regards pk

  • Java: Check if file is already open

    - by hello_world_infinity
    I need to write a custom batch File renamer. I've got the bulk of it done except I can't figure out how to check if a file is already open. I'm just using the java.io.File package and there is a canWrite() method but that doesn't seem to test if the file is in use by another program. Any ideas on how I can make this work?

  • How can I reset windows 7 file permissions?

    - by ssb
    I looked at this post and it seemed to be close to what I want, but my case might be a little worse: How can I reset my windows 7 file permissions to a rational state? Basically a while back I (very stupidly) changed the permissions on all sorts of system folders, and eventually rendered my computer virtually unusable. I managed to hack administrator privileges back onto key folders and getting it working, but in doing so I only modified permissions a lot more away from the natural state. I'm looking at this icacls stuff, but ultimately I need to reset EVERYTHING back to what it was in The Beginning, before I messed with it, from the C: directory all the way down. Right now application data is what's giving me problems, and I can't get it to work no matter how much I fiddle with those specific permissions. I will be forever grateful for help on how to do this without having to reformat.

  • Setup a local file server for two networks

    - by rzlines
    Hi I would like to setup a local linux file server (using centos and samba) that can be accessed by two independent local networks in the same house. I have 2 networks on the same floor which have Windows 7 computers, but the networks are split as we have 2 internet connections. How do I go about this? Additional info: Currently both the networks use DropBox to send files to each other but that happens via the Internet and hence its slow. Would like to achieve the same locally to increase the speed.

  • Solution for file store needing large number of simultaneous connections

    - by Tennyson H
    So I'm fairly new to large-scale architectures. We're currently using linode instances for our project, but we're brainstorming about scaling. We need a file store system than can deliver ~50mb folders (user data) to our computing instances in a reasonable amount of time (<20 sec), and scale to 10000+ total users, and perhaps 100+ simultaneous transfers. We are also unsure whether to network mount (sshfs/nfs) or just do a full transfer store-instance at the beginning and rsync instance- store at the end. I've experimented with SSH-FS between our little Linode instances but it seems to be bottlenecked at 15mb/s total bandwith, which wouldn't do under 10+ transfer stress let alone scale v. large. I also tried to investigate NFS but couldn't get it working but have little hope that it'll do within our linode network. Are there tools on other cloud providers that match our needs? Should we be mounting, or should we be transferring? Thanks very much!

    - by hgpc
    I would like to save a file downloaded from the internet in iPhone. Can I use the url as the file name? If not, what transformation should I apply to the url to obtain a valid file name? I need to find the local copy of the file later using its url.

  • C++ write to front of file

    - by user231536
    I need to open a file as ofstream and write to the front of the file, while preserving the remaining contents of the file, which will be "moved". Similar to "prepend" a file. Is this possible using the STL or boost ?

  • Settings what-opens-what once and for all (Backing up File Associations)

    - by ldigas
    Every time I switch machines (as in, get a new one, or reinstall an OS or something like that) my precious file associations get lost. And the next six months pass slowly until I again set them up right. Is there a program that allows me to: Set all the extensions I would like to open with let's say, Vim, without setting each one of them individually. Something of a kind: Vim opens: .... list of extensions ... and/or A program which lets me backup my current settings, and when I copy those to a new machine it lets me just modify the paths where I putted the applications in question, and it does the rest (again, associates that program with all the extensions it opened before).

  • Nautilus file share for multiple users is not working. Only owner gets access.

    - by Niklas
    I have always had trouble setting up samba shares with ubuntu. In the past I've tried getting it to work by configuring /etc/samba/smb.conf but never achieved what I wanted. Last time I managed to get it working by making a share with nautilus built in file sharing (which utilises samba). Now when I try do it again I doesn't work. (running ubuntu 10.10 Desktop x64) What I'm trying to achieve is a share which is available for multiple users (those who are in the same group) and not just the owner (who also is included in the group). As it is now I can connect with only the owner, the others are getting an error when I try to connect with windows 7. All the users are within the same group and the folder permissions are 770. The files and folders have the correct group settings. I think there is no restrictions in the User Settings for the other users blocking them and I marked "make available to other users (or whatever it says)" in the file sharing dialog. What can I do?

  • What is the best practice for reading a large number of custom settings from a text file?

    - by jawilmont
    So I have been looking through some code I wrote a few years ago for an economic simulation program. Each simulation has a large number of settings that can be saved to a file and later loaded back into the program to re-run the same/similar simulation. Some of the settings are optional or depend on what is being simulated. The code to read back the parameters is basically one very large switch statement (with a few nested switch statements). I was wondering if there is a better way to handle this situation. One line of the settings file might look like this: #RA:1,MT:DiscriminatoryPriceKDoubleAuction,OF:Demo Output.csv,QM:100,NT:5000,KP:0.5 //continues... And some of the code that would read that line: switch( Character.toUpperCase( s.charAt(0) ) ) { case 'R': randSeed = Integer.valueOf( s.substring(3).trim() ); break; case 'M': marketType = s.substring(3).trim(); System.err.println("MarketType: " + marketType); break; case 'O': outputFileName = s.substring(3).trim() ; break; case 'Q': quantityOfMarkets = Integer.valueOf( s.substring(3).trim() ); break; case 'N': maxTradesPerRound = Integer.valueOf( s.substring(3).trim() ); break; case 'K': kParameter = Float.valueOf( s.substring(3).trim() ); break; // continues... }

  • Delphi7 - How can i copy a file that is being written to

    - by Simon
    I have an application that logs information to a daily text file every second on a master PC. A Slave PC on the network using the same application would like to copy this text file to its local drive. I can see there is going to be file access issues. These files should be no larger than 30-40MB each. the network will be 100MB ethernet. I can see there is potential for the copying process to take longer than 1 second meaning the logging PC will need to open the file for writing while it is being read. What is the best method for the file writing(logging) and file copying procedures? I know there is the standard Windows CopyFile() procedure, however this has given me file access problems. There is also TFileStream using the fmShareDenyNone flag, but this also very occasionally gives me an access problem too (like 1 per week). What is this the best way of accomplishing this task? My current File Logging: procedure FSWriteline(Filename,Header,s : String); var LogFile : TFileStream; line : String; begin if not FileExists(filename) then begin LogFile := TFileStream.Create(FileName, fmCreate or fmShareDenyNone); try LogFile.Seek(0,soFromEnd); line := Header + #13#10; LogFile.Write(line[1],Length(line)); line := s + #13#10; LogFile.Write(line[1],Length(line)); finally logfile.Free; end; end else begin line := s + #13#10; Logfile:=tfilestream.Create(Filename,fmOpenWrite or fmShareDenyNone); try logfile.Seek(0,soFromEnd); Logfile.Write(line[1], length(line)); finally Logfile.free; end; end; end; My file copy procedure: procedure DoCopy(infile, Outfile : String); begin ForceDirectories(ExtractFilePath(outfile)); //ensure folder exists if FileAge(inFile) = FileAge(OutFile) then Exit; //they are the same modified time try { Open existing destination } fo := TFileStream.Create(Outfile, fmOpenReadWrite or fmShareDenyNone); fo.Position := 0; except { otherwise Create destination } fo := TFileStream.Create(OutFile, fmCreate or fmShareDenyNone); end; try { open source } fi := TFileStream.Create(InFile, fmOpenRead or fmShareDenyNone); try cnt:= 0; fi.Position := cnt; max := fi.Size; {start copying } Repeat dod := BLOCKSIZE; // Block size if cnt+dod>max then dod := max-cnt; if dod>0 then did := fo.CopyFrom(fi, dod); cnt:=cnt+did; Percent := Round(Cnt/Max*100); until (dod=0) finally fi.free; end; finally fo.free; end; end;

  • Benchmarking a file server

    - by Joel Coel
    I'm working on building a new file server... a simple Windows Server box with a few terabytes of disk space to share on the LAN. Pain for current hard drive prices aside :( -- I would like to get some benchmarks for this device under load compared to our old server. The old server was installed in 2005 and had 5 136GB 10K disks in RAID 5. The new server has 8 1TB disks in two RAID 10 volumes (plus a hot spare for each volume), but they're only 7.2K rpm, and of course with a much larger cache size. I'd like to get an idea of the performance expectations of the new server relative to the old. Where do I get started? I'd like to know both raw potential under different kinds of load for each server, as well an idea of what our real-world load looks like and how it will translate. Will disk load even matter, or will performance be more driven by the network connection? I could probably fumble through some disk i/o and wait counters in performance monitor, but I don't really know what to look for, which counters to watch, or for how long and when. FWIW, I'm expecting a nice improvement because of the benefits of having two different volumes and the better RAID 10 performance vs RAID 5, in spite of using slower disks... but I'd like to get an idea of how much.

  • Spurious alleged file corruption on Windows 7

    - by Johannes Rössel
    Recently my Laptop sometimes warns about corrupted files on the hard drive (Samsung SSD PB22-JS3 TM). This has only happened so far when updating (or checking out) an SVN repository with either TortoiseSVN or the command line Subversion client. The fun thing is that the corrupted file has always been a .svn directory (although the directory entry may contain files in that directory too, if they're small enough?—?which should be the case with SVN). However, when looking into the warned-about directory I notice nothing strange or unusual and don't get any more warnings about it and another try (SVN stops updating once that error occurs?—?TortoiseSVN even with an appropriate error message) of updating the working copy works (well, mostly; sometimes it does it again, albeit with a different directory). Since the laptop is only a few months old I doubt the SSD is failing already—five months of normal usage shouldn't be too surprising. Also it (so far) occurred only with SVN updates on a large repository. Maybe that's too many writes in a short time and some part between the software and the hardware doesn't quite catch up fast enough or so?—?I don't know enough about this to actually make an informed guess here. Anyone knows what's up here? ETA: Note to add: I've run chkdsk (it seems to schedule itself anyway when this happens) and it didn't find anything out of the ordinary.

  • Slow File Copy observed copying 40GB files across network to iSCSI device

    - by Rick
    Here's a curious ones for the gurus: Setup: Source Machine: Windows Server 2003 R2 machine with local hard drive. VHD file of 40GB. 1 x 1Gbps network card, Cat6 cable, switch. Target Machine: Windows Server 2008 R2 machine with iSCSI connection to iSCSI target on separate machine (1TB, RAID5). 1 x 1Gbps network card, Cat6 cable, connected to same switch as for Source Machine. Second 1Gbps network card, Cat6 cable, connected via isolated switch to the iSCSI target. Switches are Netgear JGS524 model (web managed). If I copy from the Win2003R2 machine to Win2008R2 machine local drive I get 40GB in 45 minutes, 36 seconds. If I copy from the Win2008R2 machine to the iSCSI target (local drive to iSCSI target) I get 40GB in 37 minutes 56 seconds. If I copy from the Win2003R2 machine to the iSCSI target via the Win2008R2 machine I get 40GB in 3 hours, 50 minutes, 24 seconds. All copies were done via the following command issued on the Win2008R2 box: XCOPY <source> <target> /J XCOPY /J - Copies using unbuffered I/O. Recommended for very large files. So, what's the bit I'm missing here? Why does a back-to-back copy take in total 1 hour, 23 minutes, 32 seconds when a "straight through" copy take almost 3 times as long? Switches show no errors, network hovers around the 3% utilisation mark for the duration of the copy (whereas the "back-to-back" copies are around the 25% utilisation mark). What have I missed?
