  • (win32) What to do when a file remains left open when a remote application crashes or forgets to clo

    - by Stephane R.
    Hi I have not worked so much with files: I am wondering about possible issues with accessing remote files on another computer. What if the distant application crashes and doesn't close the file ? My aim is to use this win32 function: HFILE WINAPI OpenFile(LPCSTR lpFileName, LPOFSTRUCT lpReOpenBuff, UINT uStyle); Using the flag OF_SHARE_EXCLUSIVE assures me that any concurrent access will be denied (because several machines are writing to this file from time to time). But what if the file is left open ? (application crash for example ?) How to put the file back to normal ?

  • How to append text to a text file in WinAPI?

    - by Bruce
    Hi guys, Ive got an annoying problem, I cant append any text to the text file. Every time I open it for writing, I overwrite the data. I tried to move the file pointer to the end of the file, but no result (no writing to the file at all). Here is the code: INVOKE CreateFile, offset filePath, GENERIC_WRITE, FILE_SHARE_WRITE, 0, OPEN_ALWAYS,FILE_ATTRIBUTE_NORMAL,0 mov hFile, eax mov edx, 10 INVOKE SetFilePointer, hFile, 0, 0, FILE_END INVOKE WriteFile, hFile, offset buffer, edx, ADDR SizeReadWrite, NULL INVOKE CloseHandle, hFile Any ideas? Thank you in advance!

  • Where did the text of my .html file go in text edit on mac. [closed]

    - by David
    I recently created a .html file in text edit on my mac (os x 10.5.8). I then opened that .html file in my browser and it showed the page i created just fine. I closed the .html file and text edit and refreshed the page. It still worked fine. Then i opened up the .html file in text edit again and all the text was gone (the page in the browser still works fine though). Where did all the text go?

  • What is the correct method to load an XML file and re-write it as a CVS? (C# Only)

    - by codesmack
    Hello, I have a XML file that I want to load into an unknown object type. (I say unknown object type because I am not sure what direction to go) Once I have the data loaded I need to do some processing on certain elements that are now loaded into the new object. For sake of example, we can say that the xml file is full of elements named and within the car element I need to process the element. Then once this is all done I need to write the file as a CSV file. I would like to do this is the most direct way possible. (The less code the better) I am using VS 2008 C# Thank you, CodeSmack

  • What happens if a file I want to commit to SVN is updated so often I don't manage to do a merge quic

    - by sharptooth
    Consider a situation. I want to commit a changed file to SVN and see that someone else committed the same file after I checked it out, so I have to "update" and merge changes. While I'm doing that someone commits the same file again, so when I try to commit the merged file I have to update again. Now if other users commit often enough it looks like I will never be able to commit my changes. Is that really so? How is this problem solved in real development environments?

  • How do I move the location of an xcodeproj file without breaking external build target?

    - by petFoo
    I have an Xcode project with a directory structure like this: MasterProjectDir/projectname.xcodeproj MasterProjectDir/ProjectSubDir/whatever.c MasterProjectDir/ProjectSubDir/etc.c MasterProjectDir/ProjectSubDir/Makefile My xcodeproj uses an external build target to point to the Makefile using these settings: Build Tool: /usr/bin/make Arguments: $(ACTION) Directory: ./ProjectSubDir For various reasons, I need to change the project directory structure to look like this: MasterProjectDir/projectname.xcodeproj MasterProjectDir/whatever.c MasterProjectDir/etc.c MasterProjectDir/Makefile I copied the .xcodeproj file into the ProjectSubDir and the project somehow still knows where to look for the files (?!?! - this is odd because their location is set as "relative to group" and I've just moved the xcodeproj file). It won't build. I get the following error: make: * No targets specified and no makefile found. Stop. Command /usr/bin/make failed with exit code 2 I could use a little help on this. There must be a setting I need to change somewhere.

  • Can redirection of screen output to file change the result of a C++ code?

    - by Biga
    I am having this very weird behaviour with a C++ code: It gives me different results when running with and without redirecting the screen output to a file (reproducible in cygwin and linux). I mean, if I get the same executable and run it like ./run or run it like ./run >out.log, I get different results! I use std::cout to output to screen, all lines ending with endl; I use ifstream for the input file; I use ofstream for output, all lines ending with endl. I am using g++ 4. Any idea what is going on? UPDATE: I have hard-coded the input data, so 'ifstream' is not used, and problem persists. UPDATE 2: That's getting interesting. I have probed three variables that are computed initially, and that's what I get when using with and without redirecting the output to file redirected to file: 0 -0.02 0 direct to screen: 0 -0.02 1.04083e-17 So there's a round-off difference in the code variables with and without redirecting the output! Now, why redirecting would interefere with an internal computation of the code? UPDATE 3: If I redirect to /dev/null, I get the sam behaviour as outputing direct to screen, instead of redirecting to file.

  • file_operations Question, how do i know if a process that opened a file for writing has decided to c

    - by djTeller
    Hi Kernel Gurus, I'm currently writing a simple "multicaster" module. Only one process can open a proc filesystem file for writing, and the rest can open it for reading. To do so i use the inode_operation .permission callback, I check the operation and when i detect someone open a file for writing I set a flag ON. i need a way to detect if a process that opened a file for writing has decided to close the file so i can set the flag OFF, so someone else can open for writing. Currently in case someone is open for writing i save the current-pid of that process and when the .close callback is called I check if that process is the one I saved earlier. Is there a better way to do that? Without saving the pid, perhaps checking the files that the current process has opened and it's permission... Thanks!

  • Should I use a binary or a text file for storing protobuf messages?

    - by nbolton
    Using Google protobuf, I am saving my serialized messaged data to a file - in each file there are several messages. We have both C++ and Python versions of the code, so I need to use protobuf functions that are available in both languages. I have experimented with using SerializeToArray and SerializeAsString and there seems to be the following unfortunate conditions: SerializeToArray: As suggested in one answer, the best way to use this is to prefix each message with it's data size. This would work great for C++, but in Python it doesn't look like this is possible - am I wrong? SerializeAsString: This generates a serialized string equivalent to it's binary counterpart - which I can save to a file, but what happens if one of the characters in the serialization result is \n - how do we find line endings, or the ending of messages for that matter? Update: Please allow me to rephrase slightly. As I understand it, I cannot write binary data in C++ because then our Python application cannot read the data, since it can only parse string serialized messages. Should I then instead use SerializeAsString in both C++ and Python? If yes, then is it best practice to store such data in a text file rather than a binary file? My gut feeling is binary, but as you can see this doesn't look like an option.

  • How can I manage command line arguements/variables for a script written in Perl?

    - by Structure
    I am trying to manage numerous arguments that are specified by a user when they execute a command. So far, I have been trying to limit my script design to manage arguments as flags that I can easily manage with Getopt::Long as follows: GetOptions ("a" => \$a, "b" => \$b); In this way I can check to see if a or b were specified and then execute the respective code/functions. However, I now have a case where the user can specify two arguments variables as follows: command -a black -b white This is fine, but I cannot come up with a good way to determine whether -a or -b is specified first. Therefore I do not know whether the argument variable is assigned to $ARGV[0] or $ARGV[1] after I have executed GetOptions ("a" => \$a, "b" => \$b);. How can I tell which variable is associated with -a and which is associated with -b in the example above?

  • [C++] Is it possible to use threads to speed up file reading ?

    - by Mister Mystère
    Hi there, I want to read a file as fast as possible (40k lines) [Edit : the rest is obsolete]. Edit: Andres Jaan Tack suggested a solution based on one thread per file, and I want to be sure I got this (thus this is the fastest way) : One thread per entry file reads it whole and stocks its content in a container associated (- as many containers as there are entry files) One thread calculates the linear combination of every cell read by the input threads, and stocks the results in the exit container (associated to the output file). One thread writes by block (every 4kB of data, so about 10 lines) the content of the output container. Should I deduce that I must not use m-mapped files (because the program's on standby waiting for the data) ? Thanks aforehand. Sincerely, Mister mystère.

  • How to load a .app file into iTunes from Windows?

    - by wolverine
    I have an app GotYou.app in Mac, which seems to be a single file(I know it is not, but appears to be so). And we can just drag and drop it into the iTunes in Mac. But when i copied it into windows OS for copying that into another iTunes - It appears to be a small file along with a folder. How can I copy this itunes so that I can install this into an iPhone?

  • Programatically find out a file type by looking its binary content. Possible?

    - by daemonkid
    I have a c# component that will recieve a file of the following types .doc, .pdf, .xls, .rtf These will be sent by the calling siebel legacy app as a filestream. So... [LegacyApp] {Binary file stream} [Component] The legacy app is a black box that cant be modified to tell the component what file type (doc,pdf,xls) it is sending. The component needs to read this binary stream and create a file on the filesystem with the right extension. Any ideas? Thanks for your time.

  • Easiest way to combine a dataset and other data in a single file?

    - by Tim Gradwell
    I have a dataset in C# which I can serialise using dataset.WriteXml(filename); but I want the file to contain other data as well (essentially some meta data about the dataset). I could add another table to the dataset which contained the metadata, but I'd prefer to keep it separate, if at all possible. Essentially I think I want to create a 'combination of files' file, that looks something like this: size_of_file1 file1 size_of_file2 file2 ... etc Then, I'd like to load the file into memory, and split the file into separate streams, so that I can feed the dataset into dataset.ReadXml(stream); and the metadata into something else. Sound possible? Can anyone tell me how I can do it? Thanks Tim

  • Is it possible to show the download progress of a flash file?

    - by Ólafur Waage
    I know how to setup a preloader and I have that working. But when I debug the flash application and simulate a download, it has a blank background until a few seconds have passed. I know it is "downloading" the swf file and I'm wondering if I can show a progress bar for that, or do I need to have the swf file as small as possible and pre load everything needed and have all assets as a separate file I fetch? I found something with ProgressEvent.PROGRESS but this only loads after the flash file is finished downloading.

  • How to use Crypto++ to extract the textual information in a file?

    - by JL
    I have a file that is signed with a certificate located here. CrytoAPI has not worked out for me because of server differences in 2003 / 2008+, and different file inputs. I am now considering using Crypto++ to get the job done. Essentially, all I would like to do is extract the text information from this file, and others like it, and save it as XML. There are some bits in the XML that are marked as < encoded data but those sections are just base64 encoded, so before I can get to the XML envelope, I need to deal with the certificate thats obfuscating the plain text. Anyone with experience in Crypto++ know how this is done? With CrytoAPI, I was doing something like this : byte[] fileContents = File.ReadAllBytes(outFileName); var contentInfo = new ContentInfo(fileContents); var signedCms = new SignedCms(contentInfo); signedCms.Decode(fileContents); signedCms.RemoveSignature(0); byte[] outfileContent = signedCms.ContentInfo.Content;
