  • Get user-inputed file name from JFileChooser Save dialog box

    - by Anya
    This answer to this question may seem obvious, but I'm actually struggling with it quite a bit. I've searched through JFileChooser methods in the API, and I've looked at some of the questions already asked and answered here on stackoverflow. My question is this. In my program, I am to allow the user to type in a file name which I will then use to create a brand new file that I will write on. How do you get the text the user has entered in the textfield next to the label "Save As:" on the Save dialog box provided by JFileChooser? Is there a JFileChooser method that would allow me to get that user-inputed text? Or would I have to go through another class, or do something else to get that text? Thank you so much, to anyone who answers. It's very late for me now, and this program is due in a few hours (meaning I'll be having another sleepless night). Desperate may be too strong a word, but I'm something close enough.

  • How netbeans installation file (bash file) contains Java code?

    - by Daziplqa
    Hi folks, I wonder, how a bash file can contain a Java code that is responsible about the installation of netbeans IDE which is as known is a Java based program? this is the case of netbeans: $ file netbeans-6.8-ml-java-linux.sh netbeans-6.8-ml-java-linux.sh: POSIX shell script text executable $ more netbeans-6.8-ml-java-linux.sh #!/bin/sh # # DO NOT ALTER OR REMOVE COPYRIGHT NOTICES OR THIS HEADER. # # Copyright 1997-2007 Sun Microsystems, Inc.

  • C# Binary File Compare

    - by Simon Farrow
    I'm in a situation where I want to compare two binary files. One of them is already stored on the server with a pre-calculated Crc32 in the database from when I stored it originally. I know that if the Crc is different then the files are definitely different. However, if the Crc is the same I don't know that the files are. So what I'm looking for is a nice efficient way of comparing the two streams on from the posted file and one from the file system. I'm not an expert on streams but I'm well aware that I could easily shoot myself in the foot here as far as memory usage is concerned. Any help is greatly appreciated.

  • strange messages in log file @^@^@^@^@^@^@^@^@^@^@^@^@^@^@^....

    - by celalo
    Hello, I have a application server for network operations written with JAVA based on Apache Mina. Recently I encounter a strange behavior in my log files. I noticed that the log file is full of @^@^@^@^@^@^@^@^@^@^@^@^.... characters. I mean those unexpected characters are vast amount of as such the log file gets hundreds of GB in a couple of hours! I have no clue about this problem and it is almost impossible to google it. What could be the reason? Are those set of characters any familiar to anybody? I can give more details about the application if needed. Thanks in advance.

  • One large file or multiple small files?

    - by Dan
    I have an application (currently written in Python as we iron out the specifics but eventually it will be written in C) that makes use of individual records stored in plain text files. We can't use a database and new records will need to be manually added regularly. My question is this: would it be faster to have a single file (500k-1Mb) and have my application open, loop through, find and close a file OR would it be faster to have the records separated and named using some appropriate convention so that the application could simply loop over filenames to find the data it needs? I know my question is quite general so direction to any good articles on the topic are as appreciated as much as suggestions. Thanks very much in advance for your time, Dan

  • SHAddToRecentDocs without a file?

    - by Chris Becke
    I was toying with an IRC client, integrating it with the windows 7 app bar. To get a "Frequent" or "Recent" items list one has to call SHAddToRecentDocs API. I want to add recent IRC channels visited to the Windows 7 Jumplist for the IRC application. Now, my problem is, IRC channels don't exist in the file system. And SHAddToRecentDocs seems to insist on getting some sort of file system object. Ive tried to work around it by creating a IShellItem pointing to my application, and giving it a command line to launch the channel. The shell is rebelling however, and thus far has not visibly added any of my "recent document" attempts to the Jumplist. Is there no way to do this without creating some kind of entirely unwanted filesystem object?

  • Access to variables in an asp.net user control vs an include file

    - by user204588
    I've asked this question before but couldn't get the answer I was looking for so I'm going to try it again. I'm translating pages from old asp to asp.net and I don't want to do this any other way so I really just want to know if this can be done. In asp, I'd assign a variable on one page <% myVar = "something" %> I could assign many variables here and then use an include <!--#include file="Test2.aspx"--> then in test2 file, I could access all the variables without having to pass all the variables into the control or declaring them again, like <% myVar = "something else" %> I want to do this the dot net way but I have some thirty variables on the page and i don't want to pass a bunch into the user control and I don't want to have to keep declaring the same variables. All I really want to know is if there is some way to replicate the behavior above in asp.net?

  • loading data from file into 2d array

    - by Chris
    I am just starting with perl and would like some help with arrays please. I am reading lines from a data file and splitting the line into fields: open (INFILE, $infile); do { my $linedata = <INFILE>; my @data= split ',',$linedata; .... } until eof; I then want to store the individual field values (in @data) in and array so that the array looks like the input data file ie, the first "row" of the array contains the first line of data from INFILE etc. Each line of data from the infile contains 4 values, x,y,z and w and once the data are all in the array, I have to pass the array into another program which reads the x,y,z,w and displays the w value on a screen at the point determined by the x,y,z value. I can not pas the data to the other program on a row-by-row basis as the program expects the data to in a 2d matrtix format. Any help greatly appreciated. Chris

  • How to convert thousands of PDF files to a single Postscript file in a specified order

    - by tggagne
    I've discovered multiple options for convert a few to serveral PDFs into Postscript, but many are command-line programs with command-line limitations (this application lives on .NET). Our application generates tens-of-thousands of PDFs that we need to send to a printer, except BEFORE the Postscript is printed we need to edit the Postscript to insert print command instructions (duplex, tray-pulls, highlight color, etc.) I think a perfect solution might allow us to write the PDFs to a stream, and simultaneously allow us to read the output stream so we may edit the Postscript before writing it to a file. Of course, if I must create the file first containing all 10,000 PDFs and edit it in an additional pass, I'm OK with that, too. I should mention that speed is important. I need to print 10,000 at a time, but need to keep the printers busy 24-hours/day.

  • documentBuilder: The process cannot access the file because it is being used by another process

    - by st mnmn
    I am using DocumentBuilder (of openXML api), to those who doesn't know the documentBuilder I'll give a short explanation: it has a function 'BuildDocument' which gets list of sources (each source contains wmldocument), and string of fileName to save to. public static void BuildDocument(List<Source> sources, string fileName) the purpose of this function is to build one word docx which contains all the sources. it merges some docs to one. at the end of its functionality it saves the doc using: File.WriteAllBytes(...) but when I run my project on the server I keep getting the error: "The process cannot access the file because it is being used by another process." few times it works ok. and in the visualStudio it also works without errors. what can be the problem?

  • PDB file from different versions of Visual Studio

    - by m3rLinEz
    I have an old DLL file which was built with VC++ 6. Now I need to investigate the dump file but I don't have its PDB available. The stacktrace reported by WinDbg is also inaccurate. Is it possible to rebuild the project with later versions of Visual Studio i.e. 2003, 2005, 2008, have the PDB generated, and use this to map addresses to symbols in the old DLL? Is there something like VC 6.0 compatible mode for building project? Obtaining VC++ 6 is one option, but it looks like VS6.0 has already vanished from MSDN subscriber download page :( Thanks!

  • Bad interpreter: No such file or directory

    - by user1497462
    I'm working through Michael Hartl's tutorial trying to learn Rails for the first time, and I've run into some issues. I recently reinstalled the whole Rails Installer because I had apparently inadvertently deleted some important files. Now, when I try running a test I get the following error: sh.exe": /c/Program Files (x86)/ruby-1.9.3/bin/bundle: "c:/Program: bad interpre ter: No such file or directory I checked my PATH and attempted to use the solution outlined here: Bundle command not found. Bad Interpreter ..but putting quotation marks around "C:\Program Files (x86)\ruby-1.9.3\bin" didn't do anything for me. I ran $ rails -v and got the following output: $ rails -v ?[31mCould not find multi_json-1.3.6 in any of the sources?[0m ?[33mRun `bundle install` to install missing gems.?[0m So then I tried running $bundle install and got the following issue again: Tom@TOM-PC /c/sample_app (updating-users) $ bundle install sh.exe": /c/Program Files (x86)/ruby-1.9.3/bin/bundle: "c:/Program: bad interpre ter: No such file or directory I'd really appreciate any help -- I've spent 5+ hours today trying to get back on track and am still at a loss. Thanks!

  • How to include file outside document root?

    - by Brayn
    Hey, What I want do to is to include 'file1.php' from 'domain1' into 'file2.php' on 'domain2'. So what I figured I should do is something like this: file2.php require_once '/var/www/vhosts/domain1/httpdocs/file1.php'; But this won't work for reasons I can't truly grasp. So what I did was to add my path to the include path. Something like: file2.php set_include_path(get_include_path() . PATH_SEPARATOR . "/var/www/vhosts/domain1/httpdocs"); require_once 'file1.php'; So can you please give me some hints as of where I'm doing wrong ? Thanks UPDATE - Either way I get the following error message: Fatal error: require() [function.require]: Failed opening required '/var/www/vhosts/domain1/httpdocs/file1.php' (include_path='.:/php/includes:/usr/share/pear/') in /var/www/vhosts/domain2/httpdocs/file2.php on line 4 Also I have tried this both with safe_mode On and Off. UPDATE2: Also I've changed the permissions to 777 on my test file and I've double-checked the paths to the include file in bash.

  • Java resource as file

    - by Martin Riedel
    Is there a way in Java to construct a File instance on a resource retrieved from a jar through the classloader? My application uses some files from the jar (default) or from a filesystem directory specified at runtime (user input). I'm looking for a consistent way of a) loading these files as a stream b) listing the files in the user-defined directory or the directory in the jar respectively Edit: Apparently, the ideal approach would be to stay away from java.io.File altogether. Is there a way to load a directory from the classpath and list its contents (files/entities contained in it)?

  • What's in an Eclipse .classpath/.project file?

    - by totalEclipse
    We recently had an issue with an Eclipse project for one of our team members. Tomcat was not deploying JARs of the application. We eventually noticed the .classpath Eclipse file was not the same as for the team members where the project was OK. We replaced the .classpath file with one from a project that was OK and the Tomcat deploy was complete. Just out of curiosity and to know at what to look in the future if something is wrong, what is inside the .classpath and .project files. What can I add in there, what does it all mean?
