  • Windows no longer boots on dual-boot system

    - by N Alex
    While trying to delete an Ubuntu partition from my hdd I accidentally rebooted my computer. (Note: the partition was originally made from an existing partition using paragon.) After that when I tried to start the computer I got the GRUB rescue terminal prompt. I wasn't able to do much from that, but I did manage to boot Ubuntu from a USB drive and to run boot-repair. But now when I try to select Windows 7 from the boot selection menu I get the error 0xc0000225. Here is the link to the BootInfo summary created by boot-repair: http://paste.ubuntu.com/1032584/ I have a lot of very important data on my hdd and I would really appreciate your help.

  • How can I programmatically tell if a caught IOException is because the file is being used by another

    - by Paul K
    When I open a file, I want to know if it is being used by another process so I can perform special handling; any other IOException I will bubble up. An IOException's Message property contains "The process cannot access the file 'foo' because it is being used by another process.", but this is unsuitable for programmatic detection. What is the safest, most robust way to detect a file being used by another process?

  • Joomla template parameters and params.ini - file becomes unwritable after save.

    - by Moak
    I am using wamp and creating a Joomla template with changeable parameters. initially the message is The parameter file \templates\ssc_2010\params.ini is writable! once I make changes everything works as expected, except now i get the message: The parameter file \templates\ssc_2010\params.ini is unwritable! One solution is to brows to the directory, right click the file, select properties, and uncheck read-only. Again the file is writable but once I modify the parameters again it becomes read only again. I'm quite lazy and would like to prevent this from happening again, I've notice this happening in past projects, but now I have to work a lot with parameters so it becomes quite boring doing manual labor like that :P

  • How to use C to write to flash drive bootsector despite error 'Failed to open file to write.:Permiss

    - by updateraj
    My goal is to manipulate the boot-sector in my flashdrive (volume E:) I am using XP. I am able to read the boot-sector FILE *fp_read = fopen("\\\\.\\E:", "rb"); /* Able to proceed to read boot sector */ however i am not able to open the file to write using fopen in 'wb' mode. FILE *fp_read = fopen("\\\\.\\E:", "wb"); /* Unable to proceed due to Failed to open file to write.:Permission Denied */ The flash-drive is not in use at the moment of execution. Hex-editors are able to manipulated boot sector etc, i believe it possible to do so in c. Any suggestion or insight to overcome the access problem so as to be able to write?

  • OWB 11gR2 &ndash; OMB and File Editing

    - by David Allan
    Here we will see how we can use the IDE for editing OMB scripts. The 11gR2 release is based on the common Oracle platform IDE used also by JDeveloper. It comes with a bunch of standard behavior for editing and rendering code. One of the lesser known things is that if you drop a text file into OWB you can edit it. So you can drop your tcl scripts right into OWB and edit in-place, and don’t need another IDE like Eclipse just for this task. Cool, so you have the file here. There may be no line numbers, you can toggle line numbers on by right clicking in the gutter. If we edit the file within the OWB IDE, the save is a little different from normal. OWB doesn’t normally manipulate files so things like ctrl-s to save, saves the OWB objects, but if you edit a file the closing of the file will ask if you want to save it – check it out. Now we enter the realm of ‘he who dares’…. Note the IDE doesn’t know about tcl files out of the box, so you see above there is no syntax highlighting. The code is identified by the extension… .java is java, .html is HTML etc. With OWB, the OMB scripts are tcl, we usually have .tcl extension on these files. One of the things we can do to trick up the syntax highlighting is to simply rename the file to have a .java suffix, then all of a sudden we get syntax highlighting, see the illustration here where side by side we see a the file with a .java extension and a .tcl extension. Not ideal pretending to be .java but gets us a way to having something more useful than notepad. We can then change the syntax highlighting such that we get Eclipse like highlighting within the IDE from the Tools Preferences option; You then get the Eclipse like rendering albeit using a little tweak on the file names… Might be useful if you are doing any kind of heavy duty OMB script development and just want a single IDE. The OMBPlus panel is then at hand for executing and testing it out.

  • sprite animation system height recalculating has some issues

    - by Nicolas Martel
    Basically, the way it works is that it update the frame to show every let's say 24 ticks and every time the frame update, it recalculates the height and width of the new sprite to render so that my gravity logics and stuff works well. But the problem i am having now is a bit hard to explain in words only, therefore i will use this picture to assist me The picture So what i need basically is that if let's say i froze the sprite at the first frame, then unfreeze it and freeze it at the second frame, have the second frame's sprite (let's say it's a prone move) simply stand on the foothold without starting the gravity and when switching back, have the first sprite go back on the foothold like normal without being under the foothold. I had 2 ideas on doing this but I'm not sure it's the most efficient ways to do it so i wanna hear your inputs.

  • How to identify doc, ppt, xls files

    - by Shelby. S
    So I was wondering how would you differentiate ppt, xls and doc files from each other in linux regardless of extensions. I tried 'file' but from the looks of it, all of MSOffice files are categorized under the same file type. Similarly I'm having trouble with docx, xlsx and pptx files, since they're essentially all zip files containing a bunch of xml. Thank you for your help! P.S. I also tried a python script importing the magic module, but no go.

  • Lot of "file not found" when using sudo find / -type s

    In the attempt to understand why I keep getting the following error error: 'Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)' while using the command sudo find / -type s the terminal prompted something like this find: ‘/proc/31348/task/31348/fd/5’: No such file or directory find: ‘/proc/31348/task/31348/fdinfo/5’: No such file or directory find: ‘/proc/31348/fd/5’: No such file or directory find: ‘/proc/31348/fdinfo/5’: No such file or directory What does this mean?

  • Ubuntu 12.10 automatic logout

    - by anthony
    I just had a new desktop constructed and installed ubuntu 12.10 which was successful for the most part but every time I open up some applications like thunderbird I get automatically logged out and all my windows are closed. System error messages also come up from time to time. Also I'm not sure if this helps but if I select the "Use system title bar and borders" in chromium I will also get logged out and from that point won't be able to use it without getting logged out in the future. If I click on particular links as well. If anyone has any tips on how I can isolate and fix the problem I would greatly appreciate it.

  • How to enable ajax when deriving from System.Web.UI.WebControls.WebControl on controls that are crea

    - by Dave
    I've built a class that derives from System.Web.UI.WebControl. It basically renders pagination links (same as what you see on top of GridView when enabled) for use above a repeater. I'm creating some anchor tags explicitly inside my nav control obviously, but they don't perform ajax postbacks. My understanding is that ajax requires POSTS to work right? Well, these would be GETs which I think is the problem. Is there a way to achieve what I'm trying to do? Thanks!

  • commons-exec: Executing a program on the system PATH?

    - by Stefan Kendall
    I'm trying to execute a program (convert from ImageMagick, to be specific) whose parent folder exists on the path. Ergo, when I run convert from the command line, it runs the command. The following, however, fails: String command = "convert" CommandLine commandLine = CommandLine.parse(command); commandLine.addArgument(...) ... int exitValue = executor.execute(commandLine); If I specify the full path of the convert executable (C:\Program files\...) then this code works. If I don't do this, I get an exception thrown with exit value 4. How do I get commons-exec to recognize the system path?

  • How to model interentity membership in entity-component architecture?

    - by croxis
    I'm falling in love with simple grace of entity-component design, although I still have issues breaking from MVC and OOP practices. Some of my game entities have membership relationships with each other (ex: a player is a member of a city, a city is a member of a nation), and I am unsure on the best way to implement it. My initial reaction is to have a a MemberOfCity component that points to the appropriate city component, but components are suppose to have no references to each other. My other option is to have a System do it, but that would require the system to persist data outside of a component. Is there a clean way to do this in an entity-component design, or am I trying to use a hammer on a screw and should use a hybrid/another approach?

  • Install/upgrade ubuntu from another system

    - by Samarth Agarwal
    I have a new Laptop with latest Ubuntu preinstalled on it, its 12.04. I have another laptop with Ubuntu 10.04 on it. What I lack is a fast internet connection. I want to upgrade my Ubuntu 10 laptop to a ubuntu 12 version. How is this possible without using internet connection? Can I move/copy the installation from the new laptop to the older one? Is there a way so that the newer laptop can upgrade the older one using a usb disk or dvd/cd?

  • Ubuntu 13.04 on UEFI system with Windows Boot Manager as the main loader

    - by Mehrdad
    On my old laptop (legacy BIOS, MBR disk), this was perfectly possible to get working: I turn on the computer and see the Windows Boot Manager I use EasyBCD (or BootPart, or something else) to add an option to the BCD menu which allows me to boot into GRUB, and then into Ubuntu I can't figure how to do this on my new laptop (UEFI, GPT disk), whether in UEFI or legacy mode. Currently I've installed (and even booted!) Ubuntu on my laptop, but only with the help of an external GRUB (on a USB flash drive). How can I add GRUB as an option in the Windows Boot Manager on a UEFI laptop? (No, I don't want to change my primary boot loader. So no, I don't want to overwrite the Windows boot loader with GRUB.)

  • PHP Battle System for RPG game

    - by Jay
    I posted this a while ago on stackoverflow, they thought it would be better place here, I agree. Essentially I know what I want to accomplish, and I have something to the effect of what I want but I am not satisfied with it. Here's the problem. Each user has some states: STR (how hard they hit), DEF (dodging/blocking attacks), SPD (when they can strike), and STAMINA (basically their endurance in game, if this runs out they can no longer fight and lose) What I need is something like this: UserA Stats: STR: 1,000 DEF: 2500 SPD: 2000 (HP: 1000/1000) UserB Stats: STR: 1,500 DEF: 500 SPD: 4000 (HP: 1000/1000) Because the second user has double the speed, he lands twice the amount of hits on the first user, before he gets hit. Because he has less strength than the first users defence, he will do no, to little damage. This is how the battle would theoretically go: UserB strikes UserA for 0 damage UserB strikes UserA for 0 damage UserA strikes UserB for 500 damage UserB strikes UserA for 0 damage UserB strikes UserA for 0 damage UserA strikes UserB for 500 damage, and sends him to the hospital! I was using this code, which is buggy, and not efficient, I just need a better way to do this: http://pastebin.com/15LiQQuJ Oh, and if anyone has some good ideas on how to improve the concept that would be cool too! It's not that elaborate so I'll be thinking of all sorts of things to make it more dynamic. Thanks.

  • changing system terminal colours?

    - by user88561
    So I have my computer set up just the way I want, with gnome 3 in my favorite color scheme, and the terminal in a matching background/text color scheme. Even the login screen has my Desktop background. However it is a little jarring when I shut down/use grubby and its in the default maroon and white scheme. Is there any way to change this to make it more similar to my own color scheme in terminal?

  • System speakers not recognized

    - by Kyle Maxwell
    Since upgrading to Xubuntu 13.10, sound has not functioned properly (e.g. screeching when playing Skype notifications). Now, however, it does not function at all. pavucontrol only shows Dummy Output and does not recognize the built-in speakers on my Dell Precision M4600. Possibly related, the sound indicator applet does not come up when I click on it, only showing a small white bar underneath it. I have purged and reinstalled pulseaudio. lspci -v shows: 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 04) Subsystem: Dell Precision M4600 Flags: bus master, fast devsel, latency 0, IRQ 56 Memory at f2560000 (64-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel 01:00.1 Audio device: NVIDIA Corporation GF106 High Definition Audio Controller (rev a1) Subsystem: Dell Device 14a3 Flags: bus master, fast devsel, latency 0, IRQ 17 Memory at f0080000 (32-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel The "Capabilities: <access denied" line makes me wonder if there's a permissions issue, as the Log Out applet now shows "Restart" and "Shutdown" grayed out. groups shows me in: kmaxwell adm dialout cdrom sudo dip plugdev fuse lpadmin netdev sambashare vboxusers
