  • Efficient storage in .Net App

    - by Tommy
    I'm looking for the fastest, least memory consuming, stand alone storage method available for large amounts of data for my C# app. My initial thoughts: Sql: no. not stand alone XML in flat file: no. takes too long to parse large amounts of data Other Options? Basically what i'm looking for, is a way that i can load with my applications load, keep all the data in my app, and when the data in my app changes just update the storage location.

  • file to map/reduce program

    - by vana
    Hi , I am working on extracting Parts Of speech (POS) using xml documents and I have a englishPCFG.ser.gz file which is used in extracting POS on xml files. I cannot send this .gz file as input in HDFS directory, but my program uses it for parsing xml files. The file is in my local directory. I am getting "File Not Found" error when I run my mapreduce program. How can i make it available to mapper? I tried placing the file in HDFS where my xml files are present. I also tried adding it in .jar along with class files but not luck. I tried to change the hdfs-default.xml with entry to local directory, still doesnt work. Please let me know how to make mapper read this file? Thank you,

  • Modifying groovy code at runtime in grails application

    - by parasjain01
    When I run my grails application using embedded jetty server(tomcat for grails 1.2), I can make changes to my controllers, services and other java files on-the-fly at runtime without restarting the application. How can I achieve the same functionality on my application deployed on Tomcat(or any server) for that matter. I have observed the exploded war folder under webapps has gsp files but not the groovy files.

  • C# save a file from a HTTP Request

    - by d1k_is
    Im trying to download and save a file from a HttpWebResponse but im having problems saving the file (other than Text Files) properly. I think its something to do with this part: byte[] byteArray = Encoding.UTF8.GetBytes(http.Response.Content); MemoryStream stream = new MemoryStream(byteArray); Text Files work fine with the above code but when I try to save the Content to an Image file it gets corrupted. How do i write this 'string' data to an image file (and other binary files)

  • Porting VS2005 project to VS2008

    - by lucavb
    i need to port a VS2005 Project (.NET2) to a VS2008 (.NET3.5) (or to VS2010 .NET4 not yet defined). The project is composed by: resources and configuration files (VS project files, like: .settings .vbproj .myapp .config .xconfig .Designer.vb); a lot of VB codes; xsc, xsd, xss and xsx files; a lot of Crystal reports for VS2005; graphical resources. The application take data in order to generate reports from more DB SQL Server 2005 istances. What is the best way to approach to a migration activity? Is there an internal migration tool? If yes, what's the best practice to use it? Which kind of files will be automatically ported to the new VS version? Thanks in advance for all the provided information

  • FileSystemWatcher Work is Done?

    - by Snowy
    I setup a FsWatcher on a local filesystem directory. I only want to know when files are added to the directory so they can be moved to another filesystem. I seem to be able to detect when the first file is in, but actually I want to know when all files from a given copy operation are done. If I used Windows Explorer to copy files from one directory to another, Explorer would tell me that there are n seconds left in the transfer, so while there is some activity for the begin-transfer and end-transfer for each file, it appears that there is something for the begin-transfer and end-transfer for all files. I wonder if there is something similar that I can do just with the .NET Framework. I would like to know when "all" files are in and not just a single file in a "transaction". If there is nothing baked in, maybe I should come up with some kind of waiting/countering in order to only do my activity when a job is "done". Not sure if I'm making 100% sense on this one, please anyone comment. Thanks.

  • Linux directories

    - by Alex Farber
    I am writing installation script for my program, which is supposed to run on Linux/Unix OS. What is the default directory for the following files: Executable files (programs). Program should be executed by typing its name from the command line. Shared libraries. Third-party shared libraries (the program is not open source, so I need to redistribute third-party libraries). Read-only program configuration files for all users. Configuration data available for read/write access for all users.

  • Can't find .js file in my mainBundle?!

    - by Nic Hubbard
    This is driving me crazy as I cannot figure out what in the world is going on. I load up files form you main bundle all the time, xml files, html files, etc. But, now I am trying to get the contents of a javascript file but it can never find it. I am using: NSData *jsData = [NSData dataWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"global" ofType:@"js"]]; if (jsData) { NSLog(@"%@", jsData); } else { NSLog(@"Can't find file"); return; } Even checking the [[NSBundle mainBundle] pathForResource:@"global" ofType:@"js"] string returns null. My globaly.js file is in my Resources folder, the exact location where my other files are location that work totally fine using the above method. Why can't it find my js file?

  • Design guidelines for cache mechanism

    - by Delashmate
    Hi All, I got assignment to write design for cache mechanism (this is work assignment, not homework), This is my first time writing a design document, Our program display images for doctors, and we want to reduce the parsing time of the images So we want to save the parsed data in advance (in files or inside database) Currently I have several design key ideas: Handle locks - each shared data structure should be handled, also files Test - add test to verify the data from the cache is equal to the data from the files To decouple the connection to the database- not to call directly to the database Cleanup mechanisem- to delete old files if the cahce directory exceed configurable threshold Support config file Support performance tool in the feature I will also add class diagram, data flow charts, and workflow What do you think I should add to the key ideas? Do you know good link to atricales about design? Thanks in advance, Dan

  • Account for cancelling an update process

    - by Aerus
    I'm trying to develop the logic of updating my (Java) application but I'm stuck on a particular problem. The user can, at any time, be it on purpose (by clicking the Cancel button) or unwillingly (system/power failure) cancel the update process. If the updater was busy downloading files or unpacking files and thus didn't make any changes to the main application yet, this can be easily recovered by re-downloading the files and continuing the update process like normally. But, how can i account for changes made to the main application (i.e. a file was only partially replaced, some files were corrupted, etc.) that result in a main application that can't be launched anymore? Is it possible to rollback the changes made during the update without having to keep a full backup of my application or without doing a full reinstall? Are there any standards for updating an application that can help me with this?

  • JAR file folder for eclipse projects

    - by Daff
    I'm trying to create a centralized folder (in some kind of a "meta project" in my eclipse workspace) for commonly used JAR files for referenced projects in this workspace. It should work similar to the WEB-INF/lib folder for web projects but also apply to non web projects, and automatically scan and add all jar files in this folder. I tried to create a user library with these jar files and reference them in the project but I still have to add every new jar manually to the user library (and don't know if it is referenced relative of absoulute) and Tomcat (WTP) doesn't seem to take these files (Run As - Run on Server) into its classpath (and I don't want to duplicate the jars and put them into WEB-INF/lib). Any ideas?

  • Need generated UML diagrams for C++ plugin modules

    - by archer1742
    I need various UML diagrams (sequence/collaboration, class, package, and system component) from some C++ files. However, these files are plugins in a larger programming framework. I have tried generating UML from Rational Rose 7 (2002 version), but I am not very experienced and I am unsure if RR simply cannot produce the diagram, I am doing something wrong, or the diagrams are not rendering correctly because the source files are plugins instead of standalone programs. I have also tried Star Modeler with little success and there seem to be no tutorials on how to generate these models. Is there a simple, bulletproof way to get UML diagrams for C++ files?

  • Granting administrator privileges to an application launched at startup without UAC prompt?

    - by iKenndac
    Background I've written a small C#/.NET 4.0 application that syncs various settings from a game installed in Program Files to and from other copies of the same game on different machines (think Chrome bookmark sync, but for this game). The sync itself is a relatively simple affair, dealing with files stored inside the game's Program Files folder. On my machine, this works fine without having to elevate my application through UAC. Windows 7 makes the game use Program Files virtualisation and my application works fine with that. However, on a lot of tester's machines, I'm getting reports that the application either can't work with the files and in come cases can't even see the game's folder! Having the user right-click and "Run as Administrator" solves the problem in every case. So, we just set the application's manifest to require admin privileges, right? That's fine (although not ideal) for when the user manually invokes the application or the sync process because they'll be interacting with the application and ready to accept a UAC request. However, one of the features of my application is a "Sync Automatically" option, which allows the user to "set and forget" the application. With this set, the application puts itself into the registry at HKCU\Software\Microsoft\Windows\CurrentVersion\Run to be run at startup and sits in the system tray syncing the settings in the background as needed. Obviously, I need to be smarter here. Presenting a UAC prompt as soon as the user logs in to their account or at random intervals afterwards isn't the way forwards. So, my question! What's the best way to approach a situation where I'd need to run an application at startup that needs administrator privileges? Is there a way to have the user authorise an installation that causes the system to automatically run the application with the correct privileges without a prompt at startup/login?

  • SQL Server 2008 error message from store procedure

    - by George2
    Hello everyone, When we met with such error message from store procedure, Message 1205, Level 13, State 52, the process Pr_FooV2, Line 9 Services (Process ID 111) and another process is deadlock in the lock | communication buffer resources, and has been chosen as the deadlock victim. Rerun the transaction. I am wondering whether such messages are stored in log files? I searched log folder of my SQL Server 2008 installation root (in my environment, it is C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\Log), but can not find such files. thanks in avdance, George

  • Document conversion and viewing, what are the cutting edge solutions?

    - by DigitalLawyer
    Goal: building a web application where a user can: Upload a document (doc, docx, pdf, additional office formats a +) View that document in a browser, preferably in html Download the document (in doc, pdf, additional open formats a +) Current solution: Ruby on Rails Application on Rackspace Users can upload doc and pdf files (AWS) Files can be downloaded in the format in which they were uploaded Thumbnail generation ([doc, pdf] - pdf - png) is done through AbiWord. Certain doc files do not convert well. Documents can be viewed in embedded Google docs viewer (https://docs.google.com/viewer). Certain doc files cannot be displayed. Little flexibility. Potential improvements: Document viewing in pdf through pdf.js Viewing in html (+ annotation) through Crocodoc I'd be glad to hear other users' experiences, and will add good recommendations to this list.

  • creating a full html file out of webloc in a batch mode

    - by Wordpress Newbie
    Hi, I've got over 400 bookmarks saved as .webloc files. I'd like to move them to the iPhone's goodReader app. goodReader cannot open webloc files. It can sork with pdf, html but not webloc. Do you know of a way or a program that would take a folder as its input, and convert every single .webloc file in it into a PDF version or a html version - so I can grab the converted files and move them onto iPhone. Thank you

  • How to get the recently viewed pictures on the web browser?

    - by quantity
    I want to retrieve the recently viewed pictures from IE. I know that all the files from IE exist in the internet temporary directory, commonly with the path like "C:\Documents and Settings[account]\Local Settings\Temporary Internet Files". Here something strange for me comes. I wrote a program of C++ to retrieve the directory above, and the result says it contains three subdirectories and one file. These subdirectories are Content.IE5, OIS, and OLK145, each contains lots of pictures, which I think are the ones I browsed recently on the web. The only file is desktop.ini, which is not my concern. However, when I open the directory in the file system, there are no subdirectories at all, but a lot of files, different from the ones in the subdirectories retrieved by the program. I have several questions. Frist of all, why the content of the temorary internet files seems different? Which is the actual situation about the directory? Second, I found that in filesystem explorer, the files in the directory seem like some link to the ones on the web, not physically exist on my computer, is this true? Finally, how can I get the pictures viewed from IE recently with C++, as well as their original url?

  • GDI+ on 64bit systems

    - by LaZe
    Our system uses a lot of large Bitmaps (System.Drawing.Bitmap) and sometimes we run out of memory and gets a "Parameter is not valid" error. This makes sense, since it can be difficult to allocate large continuous chunk of memory. So the question is... If we upgraded the system to 64bit, would this problem go away?

  • How to continue copying on error with copyDirectory from FileUtils (Apache Commons IO 2.4)

    - by Exocom
    I am trying to copy files from one folder to another using the FileUtils method "static void copyDirectory(File srcDir, File destDir)" from apache commons io (2.4) with the following code: String srcDir = "/sourceDirectory/examples/"; String destDir = "/tmp/examples/"; try{ FileUtils.copyDirectory(new File(srcDir), new File(destDir)); } catch (IOException e){ e.printStackTrace(); } The file structure looks like the following: examples/ (read access) examples/.subdirectory (NO access) examples/file1.txt (read access) examples/file2.txt (read access) examples/subdirectory2/file1.txt (read access) examples/subdirectory2/file2.txt (NO access) The problem is, that in srcDir there are a few files and one subdirectory I don't have access to. FileUtils.copyDirectory throws an "java.io.FileNotFoundException: .subdirectory (Permission denied)" and aborts. Is it possible to ignore those files I don't have permission to and just copy all the other files I can read?

  • Should we or should we not check in the classes folder in WEB-INF directory into SVN?

    - by Vatsala
    I use SVN, and am learning how to use it along with eclipse IDE. The first time I add classes to my package, there is no problem, the generated class files get into SVN smoothly. The moment I edit them, I get this message - "WEB-INF/classes" is obstructed. I try the "clean-up" command and the clean up command says "WEB-INF/classes" folder is locked. I use TortoiseSVN as my SVN client. I know why this is happening. It probably because the Eclipse overwrites all the files while generating classes and then causes this - Is it inappropriate to commit the class files into SVN? If not, what should I do to commit these class files smoothly?
