  • 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.

  • 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

  • Specifying path in a preference file in Unison

    - by Curious2learn
    I am using Unison to sync a folder on my local computer with one on a server. I am using a unison preference file for this. If I specify the path of the local folder using Method 1 (see below) things work well. But Method 2 does not work. I would like to use something like Method 2 because I want to use the same preference file (synced using Dropbox) on two different computers. But the usernames are different on these two computers and I cannot change the usernames. Any ideas how this can be achieved? Thank you. METHOD 1 (works) root = /Users/username1/Dropbox/path_to_folder/folder METHOD 2a (Does not work) root = ~/Dropbox/path_to_folder/folder METHOD 2b (Does not work) root = $HOME/Dropbox/path_to_folder/folder

  • 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.

  • 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

  • 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!

  • 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.

  • 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.

  • Smart auto-completition for staged git file names, used with difftool

    - by piobyz
    I'd like to have a smart auto-completition of currently staged file names when using git diff. Example: modified: DIR1/LongCamelCaseFileName.h modified: DIR1/AnotherLongCamelCaseFileName.m modified: DIR1/AndThereAreALotOfThemInDir1.m modified: DIR2/file4.m and here, using bash tab-auto-complete functionality I'd like to use it with git diff where by smart I mean that after typing git diff I'd need to type only a short part of the staged file name that I want to diff, and without a dirname, so for example git diff And<TAB> would result in git diff AndThereAreALotOfThemInDir1.m Actually, without a dir-ommiting-part it would be still useful (auto-completing using only staged files pool).

  • Mac OS X 10.9 with GCC 4.7.3, stdlib.h: no such file or directory

    - by Leon Kaihua Li
    I'm doing some development with C++ on Mac OS. The code worked fine on Mac OS 10.8.3/10.8.4, with GCC 4.7.3. However recently I upgraded my OS to Mavericks 10.9 and Xcode 5.0. I find that when I try to compile my code, both gcc/g++/clang responds with: *******.C:1:** stdlib.h:no such file or directory *******.C:2:** iostream.h:no such file or directory Since I'm not familiar with Mac OS(My working platform is openSUSE), what can I do for it? will it help if I install "Command Line Tools" from Xcode? Or is there anyway that I could re-build the include index? Include dir of GCC is /opt/local/include/gcc47 and it seems there is a stdlib.h in it. The path is /opt/local/include/gcc47/c++/tr1/ Please help me, and thank you very much.
