• Reading data file into an array C#

  - by Whitey

  I have an array like this: int[,] iMap = new int[iMapHeight, iMapWidth] { { 0, 1, 2, 3, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}, { 0, 3, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}, { 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}, { 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}, { 0, 1, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}, { 0, 0, 0, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}, { 2, 2, 2, 2, 0, 0, 0, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2}, { 0, 0, 0, 1, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}, { 0, 0, 0, 1, 1, 1, 0, 0, 3, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}, { 0, 0, 0, 0, 1, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}, { 0, 0, 0, 0, 1, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}, { 0, 0, 0, 0, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}, { 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}, { 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 3, 0, 0, 0, 0, 0, 0}, { 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}, { 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}, { 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}, { 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}, { 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 3, 0, 0, 0, 0}, { 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}, }; And I want the same thing coming from a data file. The file should be structured like this preferably: 0000000000000000000000000 0000000000000000000000000 0000000000000000000000000 0000000000000000000000000 0000000000000000000000000 0000000000000000000000000 0000000000000000000000000 0000000000000000000000000 0000000000000000000000000 0000000000000000000000000 0000000000000000000000000 0000000000000000000000000 0000000000000000000000000 0000000000000000000000000 Which will ultimately make an array like above with all values set to 0. What would be the best way to do this? Would I read one line from the file and then split each characters separately and transfer it to the new array? Or perhaps read a line, and then read each character and put that in the array? Thanks for any help.

• Calling class in Java after editing file used in as source for table

  - by user2892290

  I'm currently working on a project, I'll try to subrscibe first. I save data into text file, that I use as a source for browser of that data. The browser is based on table that contains the data. I have to rewrite the source file everytime I delete or edit data. That's where the problem comes in. After deleting or editing data I call a method to create the table again, but the table never creates. Is it possibly made by editing the file and calling the method right after that? If I restart my app the table is successfully created with right data. Take in note that I don't get any error message. This is the method I use for loading data from source file: try (BufferedReader input1 = new BufferedReader(new FileReader("./src/data.src"))) { int lines = 0; while (input1.read() != -1) { if (!(input1.readLine()).equals("")) { lines++; } } input1.close(); if (lines == 0) { JOptionPane.showMessageDialog(null, "No data to load, create a note first!"); new Writer().build(frame); } else { try (BufferedReader input = new BufferedReader(new FileReader("./src/data.src"))) { Game[] g = new Game[lines]; String currentLine; String[] help; int counter = 0; while (lines > 0) { currentLine = input.readLine(); help = currentLine.split("#"); g[counter] = new Game(help[0],help[1], help[2], help[3], help[4], help[5], help[6], help[7], help[8], help[9]); counter++; lines--; } input.close(); final JButton bButton = new backButton().create(frame, mPanel); build(g, frame, bButton); mPanel.add(panel); mPanel.add(panel2); mPanel.add(searchPanel); mPanel.add(bButton); bButton.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent e) { frame.setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR)); panel.removeAll(); frame.setCursor(Cursor.getDefaultCursor()); } }); mPanel.setPreferredSize(new Dimension(1000, 750)); panel.setBorder(new EmptyBorder(10, 10, 10, 10)); frame.setLayout(new FlowLayout()); frame.add(mPanel); frame.pack(); JMenuBar menuBar = new Menu().create(frame, mPanel); frame.setJMenuBar(menuBar); frame.setVisible(true); Rectangle rec = GraphicsEnvironment.getLocalGraphicsEnvironment().getMaximumWindowBounds(); int width = (int) rec.getWidth(); int height = (int) rec.getHeight(); frame.setBounds(1, 3, width, height); frame.addComponentListener(new ComponentAdapter() { @Override public void componentMoved(ComponentEvent e) { frame.setLocation(1, 3); } }); And this is the method I use for creating the table: String[][] tableData = new String[g.length][9]; for (int i = 0; i < tableData.length; i++) { tableData[i][0] = g[i].getChampion(); tableData[i][1] = g[i].getRole(); tableData[i][2] = g[i].getEnemy(); tableData[i][3] = g[i].getDifficulty(); tableData[i][4] = g[i].getResult(); tableData[i][5] = g[i].getScore(); tableData[i][6] = g[i].getGameType(); tableData[i][7] = g[i].getPoints(); tableData[i][8] = g[i].getLeague(); } final JLabel searchLabel = new JLabel("Search for champion played."); final JButton searchButton = new JButton("Search"); final JTextField searchText = new JTextField(20); frame.setTitle("LoL Notepad - reading your notes"); JTable table = new JTable(tableData, columnNames); final JScrollPane scrollPane = new JScrollPane(table); scrollPane.setPreferredSize(new Dimension(980, 500)); panel2.setPreferredSize(new Dimension(1000, 550)); panel2.setVisible(false); panel2.setBorder(new EmptyBorder(10, 10, 10, 10)); panel3.setVisible(false); panel.setLayout(new FlowLayout()); panel.add(scrollPane); searchPanel.add(searchLabel); searchPanel.add(searchText); searchPanel.add(searchButton); searchButton.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent e) { try { frame.setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR)); search(g, searchText.getText(), frame, bButton); frame.setCursor(Cursor.getDefaultCursor()); } catch (IOException ex) { Logger.getLogger(Reader.class.getName()).log(Level.SEVERE, null, ex); } } }); table.addMouseListener(new MouseAdapter() { @Override public void mousePressed(MouseEvent e) { if (e.getClickCount() == 1) { JTable target = (JTable) e.getSource(); panel.setVisible(false); searchPanel.setVisible(false); bButton.setVisible(false); int row = target.getSelectedRow(); specific(row, g, frame, bButton); } } });

• .resx file data inaccessible in Visual C#

  - by dsp_099

  What I'm trying to do: include some files along with the executable to extract them later. I have two projects, both with a Resource1.resx file (and some resources included from disk). In one project, I can use File.WriteAllBytes(path, Resource1.Image); to dump the resource to disk. In another, Resource1 is does not exist. I've done this before but all I can find is information about localizations (?) when I search MSDN for how to work with Resources.

• Correct folder structure for sites

  - by Francesca

  I've just started tidying up the server for a particular site and am running into some trouble when moving files. I originally had style.css in my main folder, and another folder called images, so paths in the .css went images/myimage.png Now I have moved style.css into another folder called css. So the image links in the CSS no longer work, as it's looking for the folder images from it's own CSS folder. I changed the file path to /images/myimage.png as I thought this would make it climb up a level and then look for the images folder, but this doesn't seem to work. I'm interested to see what solutions people have and also any suggestions on how people organise their folders for a particular site. Thanks!

• Batch to copy and replace a txt file from one server to another

  - by Sunny

  I have two servers, server1 and server2 on same network but require username and password to be mapped. server1 has a text file as C:\Users\output.txt. I want to create and schedule a batch script on server1, which should copy and replace output.txt file from server1 to server2 at path E:\data\output.txt on daily basis. I don't want to map server2 manually every time I start my computer nor do I want to enter my username and password each time.

• Programatically determining file "size on disk" in advance

  - by porkchop

  I need to know how big a given in-memory buffer will be as an on-disk (usb stick) file before I write it. I know that unless the size falls on the block size boundary, its likely to get rounded up, e.g. a 1 byte file takes up 4096 bytes on-disk. I'm currently doing this using GetDiskFreeSpace() to work out the disk block size, then using this to calculate the on-disk size like this: GetDiskFreeSpace(szDrive, &dwSectorsPerCluster, &dwBytesPerSector, NULL, NULL); dwBlockSize = dwSectorsPerCuster * dwBytesPerSector; if (dwInMemorySize % dwBlockSize != 0) { dwSizeOnDisk = ((dwInMemorySize / dwBlockSize) * dwBlockSize) + dwBlockSize; } else { dwSizeOnDisk = dwInMemorySize; } Which seems to work fine, BUT GetDiskFreeSpace() only works on disks up to 2GB according to MSDN. GetDiskFreeSpaceEx() doesn't return the same information, so my question is, how else can I calculate this information for drives 2GB? Is there an API call I've missed? Can I assume some hard values depending on the overall disk size?

• How to model file system operations with REST?

  - by massive

  There are obvious counterparts for some of file systems' basic operations (eg. ls and rm), but how would you implement not straightforwardly RESTful actions such as cp or mv? As answers to the question REST services - exposing non-data “actions” suggest, the preferred way of implementing cp would include GETting the resource, DELETing it and PUTting it back again with a new name. But what if I would need to do it efficiently? For instance, if the resource's size would be huge? How would I eliminate the superfluous transmission of resource's payload to client and back to the originating server? Here is an illustration. I have a resource: /videos/my_videos/2-gigabyte-video.avi and I want copy it into a new resource: /videos/johns_videos/copied-2-gigabyte-video.avi How would I implement the copy, move or other file system actions the RESTful way? Or is there even a proper way? Am I doing it all wrong?

• Bash script to find a directory, list it's contents and sub-folders info

  - by lithiumion

  Hi I want to write a script that will: 1- locate folder "store" on a *nix filesystem 2- move into that folder 3- print list of contents with last modification date 4- calculate sub-folders size This folder's absolute path changes from server to server, but the folder name remains the same always. There is a config file that contains the correct path to that folder though, but it doesn't give absolute bath to it. Sample Config: Account ON DIR-Store /hdd1 Scheduled YES ?According to the config file the absolute path would be "/hdd1/backup/store/" I need the script to grep the "/hdd1" or anything beyond the word "Config-Store", add "/backup/store/" to it, move into folder "store", print list of it's contents, and calculate sub-folders size. Until now I manually edit the script on each server to reflect the path to the "store" folder. Here is a sample script: #!/bin/bash echo " " echo " " echo "Moving Into Directory" cd /hdd1/backup/store/ echo "Listing Directory Content" echo " " ls -alh echo "*******************************" sleep 2 echo " " echo "Calculating Backup Size" echo " " du -sh store/* echo "********** Done! **********" I know I could use grep cat /etc/store.conf | grep DIR-Store Just don't know how to get around selecting the path, adding the "/backup/store/" and moving ahead. Any help will be appreciated

• Program output to file in Java (and reading it again)

  - by Cohagen

  I have a large main method in an IO class which creates objects from four different classes in my program (which all use one another to some extent). My main method takes all info in using a scanner, from the console window, and uses this info to call the constructors and methods in the other classes. As this is my first full program in Java I have been focussed on making the main method work via the console, without properly considering file input and output. I cannot see an easy way of making that work now. Ideally what I require is some way of writing everything I input to the console while running the main method to a file, in a format that can be read again and inputed back through the main method? I have refrained from posting the main method as it is 250+ lines long, but will post any relevant parts of it if required. Any help appreciated

• Two folders with identical names causing many problems.

  - by R. A. Chaucer

  In my 'Documents' folder (Win7) I have two folders with names that appear in Explorer to be identical, though their contents are different. I can rename them both to something else (eg: 'Test') and Explorer doesn't complain. The dir listing that cmd.exe and powershell gives me only lists one of them, but also lists this suspicious entry: 20/04/2010 12:16 PM <DIR> ???? Even if I rename the folders to have unique names, one of them still shows up as ???? in cmd.exe. Desktop.ini in my Documents folder doesn't contain anything out of the ordinary. Both folders appear to be read-only in their properties panel, and if I untick the read-only box it will ask me if I want to apply the action recursively, but either way when I close the panel and open it again the folder is once again read-only. They are both set to not inherit permissions. The folder that shows up correctly in the cmd.exe dir listing is the "real" one, the other seems to be automatically created when a program tries to access it. How is this possible?This is driving me nuts!

• How to delete a residual Ubuntu directory from Windows?

  - by memo1288

  I'm using Windows 7. After installing (and uninstalling) Ubuntu on my laptop, I found that it left a folder called ".Trash-1000" on my H drive. I cannot remove it: if I try to delete it from Explorer, it says: The file name you specified is not valid or too long. Specify a different file name. If I try to remove it from the command line, this is what happens: H:\>rmdir .Trash-1000 /S /Q .Trash-1000\files\Screenshot from 2013-09-24 11:57:32.png - The filename, direct ory name, or volume label syntax is incorrect. .Trash-1000\files\Screenshot from 2013-09-24 12:03:45.2.png - The filename, dire ctory name, or volume label syntax is incorrect. .Trash-1000\info\Screenshot from 2013-09-24 11:57:32.png.trashinfo - The filenam e, directory name, or volume label syntax is incorrect. .Trash-1000\info\Screenshot from 2013-09-24 12:03:45.2.png.trashinfo - The filen ame, directory name, or volume label syntax is incorrect. The files mentioned there are the contents of that folder. Using quotes around the folder name yields the same result. Trying to delete any of the sub-folders results in the same error, and trying to remove any of the files inside results in "No such file or directory". As I said before, I no longer have Ubuntu installed. How can I remove this folder?

• Access denied error while mounting a shared folder?

  - by SSH

  I am a linux newbie and I have a very basic question. I have three machines - machineA 10.108.24.132 machineB 10.108.24.133 machineC 10.108.24.134 and all those machines have Ubuntu 12.04 installed in it and I have root access to all those three machines. Now I am supposed to do below things in my above machines - Create mount point /opt/exhibitor/conf Mount the directory in all servers. sudo mount <NFS-SERVER>:/opt/exhibitor/conf /opt/exhibitor/conf/ I have already created /opt/exhibitor/conf directory in all those three machines as mentioned above. Now I am trying to create a Mount Point on all those three machines. So I followed the below process - Install NFS support files and NFS kernel server in all the above three machines $ sudo apt-get install nfs-common nfs-kernel-server Create the shared directory in all the above three machines $ mkdir /opt/exhibitor/conf/ Edited the /etc/exports and added the entry like this in all the above three machines - # /etc/exports: the access control list for filesystems which may be exported # to NFS clients. See exports(5). # # Example for NFSv2 and NFSv3: # /srv/homes hostname1(rw,sync,no_subtree_check) hostname2(ro,sync,no_subtree_check) # # Example for NFSv4: # /srv/nfs4 gss/krb5i(rw,sync,fsid=0,crossmnt,no_subtree_check) # /srv/nfs4/homes gss/krb5i(rw,sync,no_subtree_check) # /opt/exhibitor/conf/ 10.108.24.*(rw) Run exportfs in all the above three machines root@machineA:/# exportfs -rv exportfs: /etc/exports [1]: Neither 'subtree_check' or 'no_subtree_check' specified for export "10.108.24.*:/opt/exhibitor/conf/". Assuming default behaviour ('no_subtree_check'). NOTE: this default has changed since nfs-utils version 1.0.x exporting 10.108.24.*:/opt/exhibitor/conf Now I did showmount on machineA root@machineA:/# showmount -e 10.108.24.132 Export list for 10.108.24.132: /opt/exhibitor/conf 10.108.24.* And also I have started the NFS server like this in all the above three machines - sudo /etc/init.d/nfs-kernel-server start And now when I did this, I am getting an error - root@machineA:/# sudo mount -t nfs 10.108.24.132:/opt/exhibitor/conf /opt/exhibitor/conf/ mount.nfs: access denied by server while mounting 10.108.24.132:/opt/exhibitor/conf I have also tried doing the same thing from machineB and machineC as well and still I get the same error- root@machineB:/# sudo mount -t nfs 10.108.24.132:/opt/exhibitor/conf /opt/exhibitor/conf/ root@machineC:/# sudo mount -t nfs 10.108.24.132:/opt/exhibitor/conf /opt/exhibitor/conf/ Did my /etc/exports file looks good? As I have the same content in all the three machines. And also are there any logs related to NFS which I can see to find any clues? Any idea what wrong I am doing here? UPDATE:- So my etc/exports files would be like this in all the three machines - # /etc/exports: the access control list for filesystems which may be exported # to NFS clients. See exports(5). # # Example for NFSv2 and NFSv3: # /srv/homes hostname1(rw,sync,no_subtree_check) hostname2(ro,sync,no_subtree_check) # # Example for NFSv4: # /srv/nfs4 gss/krb5i(rw,sync,fsid=0,crossmnt,no_subtree_check) # /srv/nfs4/homes gss/krb5i(rw,sync,no_subtree_check) # /opt/exhibitor/conf/ 10.108.24.132(rw) /opt/exhibitor/conf/ 10.108.24.133(rw) /opt/exhibitor/conf/ 10.108.24.134(rw) Just a quick check - The IP Address that I am taking for each machine as mentioned above is like this - root@machineB:/# ifconfig eth0 Link encap:Ethernet HWaddr 00:50:56:ad:5b:a7 inet addr:10.108.24.133 Bcast:10.108.27.255 Mask:255.255.252.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:5696812 errors:0 dropped:12462 overruns:0 frame:0 TX packets:5083427 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:7904369145 (7.9 GB) TX bytes:601844910 (601.8 MB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:187144 errors:0 dropped:0 overruns:0 frame:0 TX packets:187144 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:24012302 (24.0 MB) TX bytes:24012302 (24.0 MB) Here the IP Address that I am taking for machineB is 10.108.24.133.

• Why does File::Slurp return a scalar when it should return a list?

  - by BrianH

  I am new to the File::Slurp module, and on my first test with it, it was not giving the results I was expecting. It took me a while to figure it out, so now I am interested in why I was seeing this certain behavior. My call to File::Slurp looked like this: my @array = read_file( $file ) || die "Cannot read $file\n"; I included the "die" part because I am used to doing that when opening files. My @array would always end up with the entire contents of the file in the first element of the array. Finally I took out the "|| die" section, and it started working as I expected. Here is an example to illustrate: perl -de0 Loading DB routines from perl5db.pl version 1.22 Editor support available. Enter h or `h h' for help, or `man perldebug' for more help. main::(-e:1): 0 DB<1> use File::Slurp DB<2> $file = '/usr/java6_64/copyright' DB<3> x @array1 = read_file( $file ) 0 'Licensed material - Property of IBM.' 1 'IBM(R) SDK, Java(TM) Technology Edition, Version 6' 2 'IBM(R) Runtime Environment, Java(TM) Technology Edition, Version 6' 3 '' 4 'Copyright Sun Microsystems Inc, 1992, 2008.

I have a feeling this might be more of a Perl precedence question instead of a File::Slurp question. I looked in the File::Slurp module and it looks like it is set to croak if there is a problem, so I guess the proper way to do it is to allow File::Slurp to croak for you. Now I'm just curious why I was seeing these differences.

• Problem with recursivity in rebol

  - by Rebol Tutorial

  I have a block on which I want to iterate recursively folders: [ Chrome [ content [ preferences prefpages ] ] icons [ default ] locale [ en-EN [ csbar ] ] skin ] with this function: iterate-folder: func [folders [block!]][ foreach folder folders [ either not block? folder [ probe folder temp: folder input ] [ print "folder" probe folder print "folders" probe folders probe select folders folder type-folder: type? select folders folder probe type-folder input iterate-folder select folders folder ] ] ] but for stupid reason I can't see, probe folder returns none above so it doesn't work.

  Hi, I have a website and my users can browse the website for general information. If user wants to post any data, they need to register in the website. At the time of registration (in registration form) they can upload their photo. Once registration process is completed they can even modify the previously uploaded photo. My users are facing problem while they uploading their photo at the time of registration. I have given write permission to uploading files folder. But it is giving "Access denied" error. There should be a provision to upload files with or without logging into application. How can we achieve this?

• Windows batch file to delete folders/subfolders using wildcards

  - by Marco Demaio

  I need to delete all folders in "tomin" folder, which name contains terminates with the ".delme" string. The deletion need to be done recurively: I mean on all directory and SUB directories. I though to do this: FOR /R tomin %%X IN (*.delme) DO (RD /S /Q "%%X") but it does not work, I think /R ignores wildcards. Before asking this quation I searched also in SO and found this: but the answers did not help me in solving my issue, following the suggestion given there I tried: FOR /F tomin "delims=" %%X IN ('dir /b /ad *.delme') DO RD /S /Q "%%X" But it did not work either. Any help aprreciated, thanks!

• Prevent batch file in CMD from closing without using Pause

  - by Bondye

  Currently I want to run a batch file that fires a command and show me that log. After that I need to be able to commit and view the status so this prompt may not disappear after a key press. I've searched the net and the only answer people have is pause which close the prompt after a keypress. Does anyone have the solution for me? Currently I made a shortcut to cmd.exe and made the target my folder, but I want to execute some commands also. Thanks in advance.

• File listing application on Windows : what language ?

  - by Studer

  I need to create a simple application/script able to list the hierarchy of a folder containing subfolders and files (mostly PDF), so that a user can browse easily these files and maybe have a quick preview of them. The files are all on an internal file server, so the dynamic aspects should all be client-sided. My goal (and what my boss want) is to provide some sort of an HTML page listing, to have something like this. The only problem I have now is that I cannot install anything on computers, so I cannot use PHP, Python, ... This application will only runs on Windows in Internet Explorer. What are the different possibilities I have ? I don't know if I can do this but I was thinking of using HTML + Flex. Thanks for helping.

• How to save multiple UIImage to a file iPad

  - by aron

  I have a PDF reader that displays pages of the document. What I want to do is allow the user to draw over the PDF in a transparent view. Then I want to save the drawing (UIImage) to disk. If at all possible, I don't want to have the documents folder filled with files like documentName_page01.png, documentName_page02.png for every page that is drawn over. However, I can't figure out how to store these UIImages into a single file without it becoming unwieldy and memory intensive. Any ideas appreciated.
