• Fixing corrupt files or corrupt file table on a USB drive?

  - by Kelsey

  I was doing a virus scan on an external USB drive while copying data over to it. While AVG was scanning my system got locked up I think due to the USB drive running out of space and it required a reboot. Since that time all data on the external drive is no longer accessible. I can see all the files in the root and directories but I cannot browse into any of them as Windows 7 gives an error stating they are corrupt. I think the file table or whatever it uses to store the index of what exists on the drive has been corrupted since it still shows the the drive as being almost full but everything I do a properties check on says it is 0 bytes. Does anyone know how to 'unlock' or recover this data? Is there a way to rebuild the file table somehow? Luckily I can recover this data from other sources as a last resort but I would like to fix this if possible. Any help would be appreciated. Thanks.

• Why Does DreamWeaver CS5 Discriminate between File Extensions, Even After Modding Mime Types!?

  - by Sam

  Hi folks, Even After I forced DreamWeaver CS5 to allow opening of .ast extensions as a MIME type of php5, which DreamWeaver now opens and colors correctly as described here, I still have trouble figuring out why it still discriminates between the two file extensions! Symptoms: External Files & Design View I have a file foo.php which php includes other files (e.g. the php-combined css.php and js.php). Now, when opening foo.php all functions work perfectly: the external (included) php files are all recognised correctly. However, when I change foo.php foo.ast, and open it again, It does not recognise the files extensions anymore in the top bar. Also, I lose the Design / Live View functionality.** When I change foo.ast to foo.php, all works again! Anyone any clues of why there remains a a difference between one and other extension? Note1: I have added the .ast extension to these four files, next to .php: 1 C:\Users\Sam\AppData\Local\VirtualStore\Program Files (x86)\Adobe\Adobe Dreamweaver CS5\configuration\DocumentTypes\MMDocumentTypes.xml 2 C:\Program Files (x86)\Adobe\Adobe Dreamweaver CS5\configuration\DocumentTypes\MMDocumentTypes.xml 3 C:\Users\Sam\AppData\Roaming\Adobe\Dreamweaver CS5\en_US\Configuration\Extensions.txt 4 C:\Program Files (x86)\Adobe\Adobe Dreamweaver CS5\configuration\Extensions.txt Note2: sometimes, even .php files do not want to show in design view or live view. Could this be caused by a corrupted installation?

• Is there a POSIX pathname that can't name a file?

  - by Charles Stewart

  Are there any legal paths in POSIX that cannot be associated with a file, regular or irregular? That is, for which test -e "$LEGITIMATEPOSIXPATHNAME" cannot succeed? Clarification #1: pathnames By "legal paths in POSIX", I mean ones that POSIX says are allowed, not ones that POSIX doesn't explicitly forbid. I've looked this up, and the are POSIX specification calls them character strings that: Use only characters from the portable filename character set [a-zA-Z0-9._-] (cf. http://www.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap03.html#tag_03_276); Do not begin with -; and Have length between 1 and NAME_MAX, a number unspecified for POSIX that is not less than 14. POSIX also allows that filesystems will probably be more relaxed than this, but it forbids the characters NUL and / from appearing in filenames. Note that such a paradigmatically UNIX filename as lost+found isn't FPF, according to this def. There's another constant PATH_MAX, whose use needs no further explanation. The ideal answer will use FPFs, but I'm interested in any example with filenames that POSIX doesn't expressly forbid. Clarification #2: impossibility Obviously, pathnames normally could be bound to a file. But UNIX semantics will tell you that there are special places that couldn't normally have arbitrary files created, like in the /dev directory. Are any such special places stipulated in POSIX? That is what the question is getting after.

• What's a good solution for file-tagging in linux?

  - by julien

  I've been looking for a way to tag my files and search/filter them based on those tags. Here are my (updated) requirements : any file readable by the user can be tagged freely a user can search for files matching one or several tags files can be moved around without losing the previously associated tags the system could be backed up easily no dependencies on any desktop environment if any gui is involved, there must be a cli fallback I've been hoping for some basic filesystem & coreutils hackery to handle this, but I haven' thought about this hard enough yet. Meanwhile I'll review beagle and metatracker, which have been mentionned here, and see how they perform. Ok so beagle has huge gnome dependencies, and tracker is okish, but still has some dependencies I don't like... Been doing some more research, and the way to go could very well be extended file attributes. That's a native solution for most recent filesystems, but they aren't very well supported yet (most coreutils destroys them by default, cp for example needs the -a flag to preserve them). Would like to hear some thoughts on using them while I try my hand at some hacks myself, eventhough this might warrant a new question.

• Does anybody know of existing code to read a mork file (Thunderbird Address Book)?

  - by bruceatk

  I have the need to read the Thunderbird address book on the fly. It is stored in a file format called Mork. Not a pleasant file format to read. I found a 1999 article explaining the file format. I would love to know if someone already has gone through this process and could make the code available. I found mork.pl by Jamie Zawinski (he worked on Netscape Navigator), but I was hoping for a .NET solution. I'm hoping StackOverflow will come to the rescue, because this just seems like a waste of my time to write something to read this file format when it should be so simple. I love the comments that Jamie put in his perl script. Here is my favorite part: # Let me make it clear that McCusker is a complete barking lunatic. # This is just about the stupidest file format I've ever seen.

• replace file with hardlink to another file atomically

  - by Ben Clifford

  I have two directory entries, a and b. Before, a and b point to different inodes. Afterwards, I want b to point to the same inode as a does. I want this to be safe - by which I mean if I fail somewhere, b either points to its original inode or the a inode. most especially I don't want to end up with b disappearing. mv is atomic when overwriting. ln appears to not work when the destination already exists. so it looks like i can say: ln a tmp mv tmp b which in case of failure will leave a 'tmp' file around, which is undesirable but not a disaster. Is there a better way to do this? (what I'm actually trying to do is replace files that have identical content with a single inode containing that content, shared between all directory entries)

• Regex to match the first file in a rar archive file set in Python

  - by mridang

  I need to uncompress all the files in a directory and for this I need to find the first file in the set. I'm currently doing this using a bunch of if statements and loops. Can i do this this using regex? Here's a list of files that i need to match: yes.rar yes.part1.rar yes.part01.rar yes.part001.rar yes.r01 yes.r001 These should NOT be matched: no.part2.rar no.part02.rar no.part002.rar no.part011.rar no.r002 no.r02 I found a similar regex on this thread but it seems that Python doesn't support varible length lookarounds. A single line regex would be complicated but I'll document it well and it's not a problem. It's just one of those problems you beat your heap up, over. Thanks in advance guys. :)

• Parse HTML file to grab all ID and Classes for a CSS file

  - by iamfriendly

  Hey all, A short while ago, I'm fairly certain I came across an application (or perhaps a plugin for Coda - the IDE I use) which quickly parses a html document and then spits out all of the elements with IDs and Classes for me to use in a CSS file. Having fully 'got into' zen coding - using the wonderful TEA plugin for Coda, I'm now hot on the heels of this app/plugin again. I've tried and failed miserably at hunting through Google, but have come up completely empty handed. Does anyone know of anything which can do this? Happy New Year everyone!

• How get file names using OpenFileDialog in .NET (1000+ file multiselect)

  - by Cole

  Maybe some of you have come across this before.... I am opening files for parsing. I'm using OpenFileDialog, of course, but i'm limited to a buffer of 2048 on the .FileNames string. Thus, I can only select a few hundred files. This is OK for most cases. However, fore example, I have in one case 1400 files to open. Do you know a way to do this with the open file dialog. I just want the string array of .FileNames, I pass that to parser class. I was also thinking of offering a FolderBrowserDialog option and then I'd use some other method to just loop through all the files in a directory, like the DirectoryInfo class. I'd do this as a last resort if I can't have an all in one solution.

  I have two files: fileA: date >> /root/kvno.out kvno serverXXX\$ >> /root/kvno.out fileB: foobar I need to create a new file, fileC, with the same contents as fileA, except with the string XXX being replaced with the contents of fileB: date >> /root/kvno.out kvno serverfoobar\$ >> /root/kvno.out I'd like to do this using sed. I tried some of the examples I found but I only get the contents of fileB in fileC.

• How do I write to a file and print to a terminal cuncurrently in Unix?

  - by bias

  I have a little bash function to log my Macports outputs to a file (since installs often spew little tidbits that are easy to lose in terminal noise), then I just cat the file to the terminal: function porti { command sudo port install $@ >> $1.log 2>&1; cat $1.log } Is there a way to do this concurrently? I don't care about it being in Bash, that's just how I started it. BTW I pass $@ to install but only $1 for the file name so that I can do something like: porti git-gore +bash_completion and only get the file git-core.log however someone else might prefer to include variants in the file name ...

• Blackberry JDE generating bad .jad file (does not match compiled .cod file)

  - by matkas

  I Have a BB application that gets compiled into 3 siblings cod file. ( actualy one cod fil contaning 3 sub cod files). app.cod |--app.cod |--app-1.cod |--app-2.cod which is normal. the jad refers to those 3 inner .cod files. Now I have add some feature to my app, it is getting a little bit bigger. the jad now refers to 4 inner .cod files. but there is still 3 inside the app.cod that is generated. so I now still have app.cod |--app.cod |--app-1.cod |--app-2.cod but with the jad refering to app.cod app-1.cod app-2.cod AND app-3.cod. what is wrong the my compiled program? is it a bug from the JDE? I am using JDE 4.5.

• Can .NET load and parse a properties file equivalent to Java Properties class?

  - by Tai Squared

  Is there an easy way in C# to read a properties file that has each property on a separate line followed by an equals sign and the value, such as the following: ServerName=prod-srv1 Port=8888 CustomProperty=Any value In Java, the Properties class handles this parsing easily: Properties myProperties=new Properties(); FileInputStream fis = new FileInputStream (new File("CustomProps.properties")); myProperties.load(fis); System.out.println(myProperties.getProperty("ServerName")); System.out.println(myProperties.getProperty("CustomProperty")); I can easily load the file in C# and parse each line, but is there a built in way to easily get a property without having to parse out the key name and equals sign myself? The C# information I have found seems to always favor XML, but this is an existing file that I don't control and I would prefer to keep it in the existing format as it will require more time to get another team to change it to XML than parsing the existing file.

• Sharing a connection string

  - by coure06

  hi, I am developing a class library (C#) that i will use it for my different projects (later). My class library dll will use the connection string /data context of the project which will reference my new dll. How can i do it? Lets say i have a class Library Project named "CLP", and a website project "WP". I can add reference to CLP.dll file but how i will pass a connection string/data context object to that dll? as CLP.dll will access db based on the connection string of the "WP". Not sure my problem is clear or not!

• sharing web user controls across projects.

  - by Kyle

  I've done this using a regular .cs file that just extends System.Web.UI.UserControl and then included the assembly of the project that contains the control into other projects. I've also created .ascx files in one project then copied all ascx files from a specified folder in the properties-Build Events-Pre-build event. Now what I want to do is a combination of those two: I want to be able to use ascx files that I build in one project, in all of my other projects but I want to include them just using assembly references rather than having to copy them to my "secondary" projects as that seems a ghetto way to accomplish what I want to do. It works yes, but it's not very elegant. Can anyone let me know if this even possible, and if so, what the best way to approach this is?

• LINQ-to-SQL and SQL Compact - database file sharing problem

  - by Eye of Hell

  Hello. I'm learing LINQ-to-SQL right now and i have wrote a simple application that define SQL data: [Table( Name = "items" )] public class Item { [ Column( IsPrimaryKey = true, IsDbGenerated = true ) ] public int Id; [ Column ] public string Name; } I have launched 2 copy of application connected to the same .sdf file and tested if all database modifications in one application affects another application. But strange thing arise. If i use InsertOnSubmit() and DeleteOnSubmit() in one application, added/removed items are instantly visible in other application via 'select' LINQ queue. But if i try to modify 'Name' field in one application, it is NOT visible in other applicaton until it reconnects the database :(. The test code i use: var Items = from c in db.Items where Id == c.Id select c; foreach( var Item in Items ) { Item.Name = "new name"; break; } db.SubmitChanges(); Can anyone suggest what i'm doing wrong and why InsertOnSubmit()/DeleteOnSubmit works and SubmitChanges() don't?

• when using a FTPS connection to transfer a file, what is the difference between a 'Binary mode taran

  - by shaleen mohan

  I am using a FTPS connection to send a text file [this file will contain EDI(Electronic Data Interchange) information]to a mailbox INOVIS.I have configured the system to open a FTPS connection and using the PUT command I write the file to a folder on the FTP server. The problem is: what mode of file transfer should I use? How do I switch between modes? Moreover which mode is the 'best-practice' to use when transferring file over FTPS connection. If some one can provide me a small ftp script it would be helpful.

  Why does eclipse break with the error "Could not write file: M:\workspaces\eclipse\project.project. M:\workspaces\eclipse\project.project (Access is denied)" when the .project file is hidden (on the Windows file system)? Note: This happens w/ other files as well. Steps to Reproduce: 1. Install the latest eclipse, I am using eclipse-jee-galileo-SR2-win32.zip. (Not sure if it happens in other versions) 2. Create a project. 3. Browse to the project in windows explorer, find the .project file. 4. Right click - properties 5. Under Attributes check hidden. 6.

• Sharing beans from contextListener -- dispatcher servlet

  - by Ernest

  Hello! ok, i have another question now. I have a bunch of beans loaded succesfully in applicationContext.xml, which loads from web.xml: contextConfigLocation applicationContext.xml org.springframework.web.context.ContextLoaderListener Here are is the bean defined in applicationContext.xml that i want to share: it loads other beans (DAOs) which are initialized with hibernet. I need to acces catalogFacadeTarget from the dispatcherServlet, declared in web.xml: dispatcher org.springframework.web.servlet.DispatcherServlet 1 <servlet-mapping> <servlet-name>dispatcher</servlet-name> <url-pattern>*.htm</url-pattern> </servlet-mapping> and configured dispatcher-servlet.xml like this: welcome There! in the property called catalogFacadeImpl. If you need the entire applicationCOntext.xml, web.xml, and dispatcher-servlet.xml please let me know. From what i read, i should be able to share beans if i declared them in the contextConfigLocation configuration file. Thank you very much in advance.

• Sharing a mex64 file across computers

  - by Shaihi

  I have a mex64 dll compiled on my machine. I used Matlab 2009b with VS2008 Pro to compile the dll. The dll works fine on my Matlab installation. I want a colleague to use the dll so I sent it to him and he gets the following error message when trying to use the dll: ??? Invalid MEX-file 'filename.mexw64': The specified module could not be found. My current assumption is that this is caused because he uses an older Matlab version or missing a dll that I have. I ran dependency checker and asked him to check that he has all the listed dlls. I am still waiting for him to confirm his Matlab version. What other reasons can cause this and can the Matlab version make a difference? (I mean R2009a when I have R2009B and not a huge version diff)

• Delphi: how to efficently read a big binary file, converting it to hexadecimal for passing it as a v

  - by user193655

  I need to convert a binary file (a zip file) into hexadecimal representation, to then send it to sql-server as a varbinary(max) function parameter. A full example (using a very small file!) is: 1) my file contains the following bits 000011110000111 2) I need a procedure to QUICKLY convert it to 0F0F 3) I will call a sql server function passing 0x0F0F as parameter The problem is that I have large files (up to 100MB, even if average file size is 100KB files are possible), so I need the fastest way to do this. Otherwise stated: I need to create the string '0x'+BinaryDataInHexadecimalRepresentation in the most efficient way. Related question: passing hexadecimal data to sql server

• SSIS - Can I get the column schema for a flat file source from a database?

  - by Steve Clement

  We receive a nightly data export from a vendor in the form of about 10 tab-delimited flat file without column headers. In addition, the vendor provides us with the SQL scripts for the database tables so that we can import the files into our system. Unfortunately, the vendor recently changed the schema for the flat files. Each file has upwards 150 columns, and having to go through the DB schema and adjust column types on a Flat File Data Source in SSIS is extremely time consuming, not to mention a royal pain. Since I know the file data layout in the database schema, is there any way I can dynamically pull that into a Flat File source to set the columns correctly? Or am I just stuck with manually setting everything?

• Sharing [config] data across modules,functions

  - by williamstw

  I have some configuration data in a config file that I read off disk when the app starts. I need to make that configuration data available to other functions/modules in the application. I started down the path of looking into ets/mnesia to store the data on startup to make it shared among all processes, but then my inner voice cautioned me that there must be a more functional, erlang-y way to do this. The only alternate approach I've come up with so far is setting up a module that has an actor loop that reads the data on startup and responds to messages like {Key, From} and responds by From ! {ok,Value}. Then, I gave up and decided to ask... Thanks, --tim
