Programming :: What Is The Terminology Called Of A Binary Using A File That Is Not Part Of It's Self
Feb 14, 2011
What is the Terminology called of a Binary using a file that is not part of it's self? An example would be when a browser uses a HTML file for it's interface. The binaries code has to know how to find it and so on. I imagine that the applications binary uses a system call and that another application takes over.
I feel there's a bit of a misunderstanding going on between C++ and me...My problem is that I have a deque of pointers to a class, and create objects then add them to the deque in a for loop. However, the destructor is called on the object as soon as the loop quits.
Code:
This prints:
Code:
Now, if I change the deque from deque<Test*> to deque<Test> then it works fine - I get:
Code:
However, I can't do this with my actual code, because I am creating a deque of pointers to an abstract class, so it won't let me instantiate the class. (This is all so that I can take advantage of polymorphism, and call functions on a set of similar objects without worrying what type of object I'm dealing with).
So, I suppose my question is: what is the correct way to create that deque of pointers to the abstract class? I don't seem to be barking up the right tree currently.
I have a .txt-file with ~50.000 lines of numbers, generated by a mathematics program. From this file, I need line ~ 1.100 to line ~16.000 (these lines are always the same btw, this may make the solution easier, dunno) to be copy/pasted to another file, where the lines ~500 to ~15.000 (also, every time the same) should be overwritten by the aforementioned lines...I haven't found or come up with anything that works yet, mostly I find solutions to copy everything from one file to another but I can't find something to specifically overwrite a part of a file with part of another.
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.
I have this string ./DAT000728-652523058.job.I want to extract the no between DAT and - sign. I want 728. I dont want 000728.echo ./DAT000725-560162365.job | cut -d'T' -f2 | cut -d'-' -f1 I am getting 000728.string can be ./DAT326822-652523058.job also. then i need 326822
There are a few things I was wondering about (using tools available in bash):How to insert a file at at the specified location of another.How to copy a portion of a file between two lines matching a regex to another file (and/or making sed only work between two lines matching a regex)How would you do this?
I'm trying to compile a simple script for a ar71xx (bleeding edge /from snapshots) Openwrt router.I have previously compiled scripts for Kamikaze 8.09. I just copied the gcc file inside the SDK dir and used it without problems.
i need to change a binary file, let's say to find and replace username:
find string: "/home/name/bla-bla-bla/ " new string: "/home/anewname/bla-bla-bla/ "
i can do it, for example, in emacs (hexl-mode), but interesting in writing a script instead. it will be much more better for me if i could do it automatically. is there an analog of: sed 's/string1/string2/g' ? P.S. the best way is to recompile the binary files i have, but there are no sources available.
I want to be able to disassemble a binary file, modify the assembly source, then assemble the modified assembly source back into a modified binary file. Purpose for this is pretty much just to play around with the Crackmes (www.crackmes.de) game.
Now, disassembly is easy, there are several tools that do it, including the standard objdump with the -d argument. However, how would you assemble an assembly source file created with objdump -d? GCC for sure doesn't want to assemble it in that format. What program, script, or arguments to GCC (none that I can think of) can be used to accomplish this? If someone also has some good tips for tools in general for Crackmes beyond what is standard in GNU/Linux I'd love to hear about it.
I have a binary file, which I need to process using my C++ application. Only thing I know is first chunk of the file is long, second chunk is int, third chunk is char etc... The binary file actually contains something like below. (which is represented in hex base).
D7 07 00 00 00 00 00 00 37 18 00 00 DE 07 ............ so on.....
I need to procees the file in the following way.
* I know the first data segment in my file is long. So it takes 4 bytes. * so I need to read the first four bytes. That is D7 07 00 00. * Then I need to reverse this as 00 00 07 D7. * Finally I need to get the decimal value of above hexa decimal line. ( 00 00 07 D7) * i.e. 00 00 07 D7 (in hex) = 7D7 (in hex- after removing leading 0 s) = 2007 (in decimal)
I work for a company that does remote computer support, we use VNC protocol to help our clients. I installed a VNC repeater that allows my clients to connect to me going through all firewalls and port forwarding. The linux VNC repeater outputs all connection information to /var/log/vnc.log and looks something like
Code:
UltraVnc Linux Repeater version 0.14 UltraVnc Tue Mar 22 03:37:02 2011 > routeConnections(): starting select() loop, terminate with ctrl+c UltraVnc Tue Mar 22 03:37:12 2011 > acceptConnection(): connection accepted ok from ip: 55.555.555.55
[code].....
I need a script that reads this log file every so often (30 seconds to 5 minutes) and sends an email when an connection has been accepted. I looked into reading log files and got this so far
Code:
LOG=/var/adm/sqllog while true do tail -100 $LOG | grep "ORA" > /dev/null
I'm running Linux version 2.6.33.4 on an ARM9 and can successfully copy directly into the framebuffer using the command:
Code: cat /usr/myfile.bin >/dev/fb0
I converted myfile.bin from a 640 x 480 x 24 bmp.
What I'd like to do is to have the ability to dump .bin image files directly into the framebuffer from a C program without shelling out to a cat command.
My assessment is making a tree from a text file as follows: -reading a file line by line
-making a binary tree from it - traverse by level the binary tree - posting the traversal result to the same file without overwriting the text file- it is required to be append to the bottom of the text file (i have to do this in 4 languages: c#,PHP from Xampp,java, python)
i read the file with this script in java: public class FileToStringArray { privateString strLine; privateString[] stringArray; privateFileInputStream in;
I need to read a binary file using my C++ application. That binary file may contain arbitary characters and it also contains 0 at some places. I need to read the file without considering null terminating character. (i.e. considering 0 as a normal byte and not as the end of the string)Can some one suggest me a method to read the buffer while ignoring the null terminated character.
I am accessing a firewire camera using the libdc1394 library and saving the image as a PPM file, using the code below:
[Code].....
My question is whether the above code is portable. I presume it is, since the result is a binary PPM file which should be capable of being read across multiple computers with different architectures and different operating systems. But at the same time, all that the above code is doing is just saving the binary representation of unsigned chars on the harddrive, and there does not seem to be any reason why the binary representations of the unsigned chars will be identical across multiple computers.
I wanted to know how can I cross compile SMS SERVER TOOL for an embedded computer and make just one binary file for it or how can I change all of its default files places like its demon and object file and gather all of them to one directory to execute and use and run.let me explain it better for you : I have an embedded computer with Linux OS that its file system is read only and I can not add any file to /usr /lib and ..... and I can just mount a SD memory card to it and copy all of my programs to it and run them from there as you understand I have two choices to choose, first make one big binary file for each program that I am doing it now and it is not a suitable solution and the second is finding the way to change default place of shared object file of my program.now you tell me what can I do to solving this problem.
When reading the man pages and --help for rpm and yum, it is hard to know if the command concerns the stuff already installed or the contents of some repository. For example, sometimes one wants to search for stuff installed on one's machine that match a pattern, and at other times, one wants to find all the candidate things that one can install on one's machine based on a pattern match.
Please clarify the terminology used by the rpm and yum documentation regarding whether the command refers to stuff already installed or stuff being offered for installation at some repositories. (Regarding "list": I think list always refers to a list of the contents of packages; and never to either of a list of the packages installed on one's machine or a list of the packages on some remote repository offered for installation.)
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'm using Ubuntu for about a half year. Currently version 10.10. The next problem I have with Nautilus: He have it in ListView. If I want to rename a file then the entire file is selected and not only the first part. So the file extension is also selected. I think this is a bug, whoich can be found on the Internet, but I do not find a solution. Does anyone here have a solution?
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.
I have our own C written program code which is communicating with a third party C++ written program code to run a moving device. We have successfully communicated with the third party code with wrapper functions. (Thanks to member in LQ that helped me solved this.)Now, we tried to run some functions to move the device. I think it is better for me to attach the related code first. pro.c (The source code we used to run the device)
x is a variable which is taken from a very beg text file > 64MB
first line of my code is cout<<" Wait Running...";
my code takes text file as an input, takes its data and generates an output text file....
Code is running fine for small data tried till x= 10
but while trying to run with large data ie x = 5000000 approx it is giving error Even the first line of the code is not displayed. NOTE: variable is declared global but its size is defined in main.
The error that i am getting after approx 2-3 minutes is:
terminate called after throwing an instance of 'std::bad_alloc' what(): std::bad_alloc Wait Running...Aborted (core dumped)
