Software :: Read Binary File In C But Code Is Not Working Properly?
Aug 7, 2010
I am trying to read binary file in c but my code is not working properly. I am not getting the same output as that in file. you can view my code below.
I am trying to write a C++ Code to read write a XML file in C++.I researched a lot and find xerces is used for that but I am not able to write the code for that.Please provide me some links on how to run a code that R/W a xml file in C++.
I bought a new SD card which I intend to put some MP3s on - except that I can't write to it because it tells me the destination is Read Only. No-probs thinks I: I'll just reformat it.
"Error creating file system: helper exited with exit code 1: cannot open /dev/mmcblk0p1: Read-only file system"
Various chmod commands all result in Read-only file system. I tried umount then mount commands, but it couldn't find it to mount once I'd unmounted it using the same /media/ file path (I assume it's the only one).
What are the possible problem when Windows access the file from Ubuntu got Read Only even though have a full permission to read, write and execute the file? Ubuntu to Ubuntu accessing the file there is no problem only Windows got a problem.
I use Lucid Lynx and Gnome. This morning, I was restarting Parley from command-line to understand why it didn't played mp3 files. On restarting Parley, I pointed out that my file was reseted. This is what was written on my terminal and the content of my file.
Code: Parley(4722): "Could not open or properly read "/media/Documents_/Parley/Anglais/Vrac.kvtml" (Error reported: unexpected end of file)" "Error Opening File"
I have a problem to get it to work. The installer seems to read the preseed-file alright, and some of the values defined in the preseed-file are taken into account. The questions regarding locale, keyboard layout and time zone are answered using the preseed-file, but in the user account creation-step the process goes wrong. The Full name-field is obtained from the preseed-file, but the login-name is generated by the installer and not read from the preseed. Also the password-fields are empty and not filled in. Also the script that I've defined with preseed/late_command is never run.
I tried searching the forums but no-one had exactly this kind of problem, so it makes me think that this has to be some trivial error I'm doing. Could someone take a look at these configs and see if there's something wrong with them? How should I continue resolving this?
I have some files which are UTF8 and have first line as blank. It shows as data file by "file" command. If I remove the blank line, it shows it as UTF8 text file. I have to choose displayable text files from many files, so I used "file" command.
Note: I do not have permission to attach file. So not able to attach sample file here.
I am having problems with scp during a backup operationI added a ps -ef before and after the scp operation used during the backup.The backup is a script to backup a Zimbra ServerI am including the code segment that I am having problems
Code: # DRCP Section. To scp newly created archives to a remote system if [ "$DRCP" = "yes" ]
I've had Ubuntu 11.04 installed on my desktop since it's release. Up until an hour ago, it was working fine. I clicked on an update from the update manager, now booting into a graphical mode is completely broken, (the start-up load hangs at 'Check Battery State ... [0k]'). I restarted my computer, and booted into safe mode, and launched the terminal. This all works fine. I then typed :
Code: sudo gdm start into the command prompt, hoping that I would be able to start things manually. Instead, it spat out this: Code:
gdm-binary[230]: WARNING: Unable to load file '/etc/gdm/custom.conf'. No such file or directory. gdm-binary[230]: WARNING: Unable to find users : no seat-id found. gdm-binary[230]: WARNING: Gdm Display: display lasted 0.070467 seconds
The last line was printed about 8 times, with slightly different times, before it gave up and failed. Some information which might help, I have Gnome 2, Unity and KDE (not sure which version), installed. My graphics card is the GTX 275, and I have driver the Nvidia driver 275.21. So yeah, I think the update has gone and moved custom.conf somewhere, but I have no idea on how to fix it. I have a graphics programming assignment due on Friday and I would be eternally grateful if I could get this fixed well before then.
In a project I'm working on with a few other people, I got the task of writing an assembler. The last thing I do is convert the commands into a binary representation, and jam it into a file. Now one of my teammates said he'd like to be able to "reference" the code within another program. He said he'd be able to do this if the file I output is a Linux object file. I'm thinking it'd also work as an executable. Anyway, he said he'd like to be able to grab the file and reference the binary by address. I'm still fuzzy on this, and if you're confused with what I said here, please tell me so I can ask him for better details.Anyway, I'm aware that gcc can compile files to ".o", but that's only for C/C++, and my file is just binary. I'm also aware of "ld", but I haven't seen any use of it to help me. I'm happy to hear suggestions as to what I can do. If anything, I think I'll implement a few functions to grab the bits and hand them to him in an array or something.
the version of vsftpd i read is 1.2.1, i find the following code in main.c: struct vsf_sysutil_statbuf* p_statbuf = 0; but i cannot find the definition of this structure.then anybody here can tell me what is the definition of vsf_sysutil_statbuf struct?
I had a problem with apache2 and getting .htaccess working. I have done some things and i believe its working the ErrorDocument command is anyway. I believe there may be some problems with the rewrites though.Im trying to take a urlhttp://localhost/showthread/123and make it display whats on http://localhost/index.php?showthread=123The rewrite rule is Quote:

I am a beginner in ubuntu and only recently did i install Ubuntu 10.10 using Wubi. I am dual booting along with Windows 7 64bit. Before I got to know of Wubi, I created a free 20GB partition for installing linux. But since it was of no use, I decided to extend another partition adding this 20GB space. The problem now is that I am getting the following error while trying to access the partition.
"Error mounting: mount exited with exit code 12: Failed to read last sector (605949951): Invalid argument HINTS: Either the volume is a RAID/LDM but it wasn't setup yet, or it was not setup correctly (e.g. by not using mdadm --build ...), or a wrong device is tried to be mounted, or the partition table is corrupt (partition is smaller than NTFS), or the NTFS boot sector is corrupt (NTFS size is not valid). Failed to mount '/dev/sda5': Invalid argument The device '/dev/sda5' doesn't seem to have a valid NTFS. Maybe the wrong device is used? Or the whole disk instead of a partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?"
These are the results after running sudo fdisk -l /dev/sda: "Disk /dev/sda: 640.1 GB, 640135028736 bytes 255 heads, 63 sectors/track, 77825 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x76c4009c

I was just reading about the whole boot process on computers and am curious as to why the BIOS can only read and execute code and data from only cylinder 0, track 0 and sector 1 of the disk being booted from? Why can't the BIOS read from any other disk location?
I am trying out an open source software According to its installation instruction, "Linux users with an x86 compatible platform can use the frozen package for a quick installation (Just unpack the tar file in directory an start the faces binary). "So I just did it and unpacked it. However, when I click on the application file, which is named "faces", nothing happens. I'm new to Ubuntu so I'm not sure if there is anything that I should do before I can click and run an application like this?
I'm new to Fedora, and haven't used any flavor of Linux in years. I'm attempting to run a few benchmarks that were given to me by my instructor, but every one I try to run gives an error "Cannot execute binary file". For instance,.inp.inThis command gives an error:bash: ./Mcf: cannot execute binary fileIt is not a permission problem, I have confirmed the file has execute permissions (one of the things I still remembered after all these years). I suspect all the benchmarks I have been given were compiled on Ubuntu. Would this be causing the problem? I do not have access to the source code, so I cannot recompile. If that is the problem, is there a way around it that doesn't involve throwing away a weekend and starting fresh on Ubuntu?
I found a Linux .x86 binary file that I've been looking for, but not sure what to do with it. Does this (*.x86) binary file format seem like something that could simply be run by command, or something that would need to be compiled first? There is not much information that I could find regarding the particularly file.
I'm trying to install this app called genBlast. It's a bioinformatics tool that does some cool stuff (I guess the actual use doesn't matter that much). Anyway, it comes as a .tar.gz folder with about a dozen executables in it; no compiling necessary. I extracted it to the desktop so I didn't have to worry about permissions, and then just tried to run it from inside the directory (it's a command line app).
All of the executables work with a ./ except one, and it's the most important one for that matter. When I go to run it, I get the error message Code: bash: ./genblast: cannot execute binary file I've checked permissions with ls -l, run a chmod 'u+x' just to make sure, and everything else I can think of. But it just won't work. Also, I just installed it on another computer and it works fine, so I'm pretty sure it's on my end.
I want run binary files but shoot my errors that "Cannot Execute Binary file" I try with ./file, bash file etc i'm using fedora12 with KDE Desktop this happends with all binary files
I tried to restart my httpd service.cannot execute binary file seems like the HTTPD wasnt stopped while it should be stopped. it skipped the 'stop' and just right away jump into 'start' command. my case is i just changed some php.ini configuration, and to have it changed i need to restart after changes.am i correct if i say my '/bin/rm' and '/bin/touch' files are corrupted?
