• 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?

• Use parameters with CTL

  - by Hal

  Hi. I am using a CTL file to load data stored in a file to a specific table in my Oracle database. Currently, I launch the loader file using the following command line: sqlldr user/pwd@db data=my_data_file control=my_loader.ctl I would like to know if it is possible to use specify parameters to be retrieved in the CTL file. Also, is it possible to retrieve the name of the data file used by the CTL to fill the table ?I also would like to insert it for each row. I currently have to call a procedure to update previously inserted records. Any help would be appreciated !

• How to understand the output of the PHP regex matching below?

  - by smarty

  $file = '{include file="{$COMMON_TPL_PATH}common/header_admin.tpl"} {include file="{$mainPage}"} {include file="{$COMMON_TPL_PATH}common/footer_admin.tpl"}'; preg_match('/^(\{\})|^(\{\*([\S\s]*?)\*\})|^(<\?(?:php\w+|=|[a-zA-Z]+)?)|^([ ]*[ ]+[ ]*)|^(\{strip\})|^(\{\/strip\})|^(\{literal\})|^(\{\s{1,}\/)|^(\{\s{1,})|^(\{\/)|^(\{)|^(([\S\s]*?)(?=([ ]*[ ]+[ ]*|\{|<\?)))|^([\S\s]+)/', $file, $matches); var_dump($matches); Why the output is: array(13) { [0]=> string(1) "{" [1]=> string(0) "" [2]=> string(0) "" [3]=> string(0) "" [4]=> string(0) "" [5]=> string(0) "" [6]=> string(0) "" [7]=> string(0) "" [8]=> string(0) "" [9]=> string(0) "" [10]=> string(0) "" [11]=> string(0) "" [12]=> string(1) "{" } It seems to me that ^([\S\s]+) can match the whole string..

• How to pass parameters with spaces via cstdlib system

  - by buchtak

  Hi, I have this windows console app which takes a file, do some calculations, and then writes the output to a specified file. The input is specified in "app.exe -input fullfilename" format. I need to call this application from my C++ program, but I have a problem with spaces in paths to files. When I call the app directly from cmd.exe by typing (without specifying output file for clarity) "c:\first path\app.exe" -input "c:\second path\input.file" everything works as expected. But, when I try using cstdlib std::system() function, i.e. std::system(" \"c:\\first path\\app.exe\" -input \"c:\\second path\\input.file\" "); the console prints out that c:\first is not any valid command. It's probably common mistake and has simple solution, but I have been unable to find any. Thx for any help.

• Is there any way to prevent a Delphi application from using Virtual Storage on Vista/Win 7 without e

  - by croceldon

  The question pretty much says it all. I have an app with an older component that doesn't work right if runtime themes are enabled. But if I don't enable them, the app always ends up messing with the virtual store. Thanks! Update: Using Mark's solution below, the application no longer writes to the Virtual Store. But, now it won't access a tdb file (Tiny Database file) that it needs. This tdb file is the same file that was being written to the Virtual store. Any ideas on how I can give it access to the tdb file and still prevent writing the Virtual Store?

• Mericural "no username supplied" error on Mac

  - by theDuncs

  I've just installed Mercurial on my Mountain Lion Max (10.8) and on my first commit I'm getting the error: abort: no username supplied (see "hg help config") I've seen a load of answers which suggest I need to create or copy a file form a certain location and paste it into another location and add my username and email to the document. If that is the right thing to do: Where is the file I need to copy (or what is the file called that I need to create) Where do I put that file Do I just need to add the following two lines to the file? [ui] username = Your Name Thanks guys.

• How are files (especially audio files) organized internally?

  - by mystify

  I try to grok that: Apple is talking about "packets" in audio files, and there is a fancy function called AudioFileReadPackets which takes a lot of arguments. One of them specifies the "start packet", and another one the number of packets which you want to read. So I imagine an audio file to look like this, internally: It's made up of a lot of packets. If it's an audio file which has an variable bit rate format, then every packet may have a different size. If the file has an constant bit rate format, then every packet is the same size. So an audio file is like a truck full of boxes, and every box contains some interesting stuff. Is that correct? Does it apply to any kind of file? Is this how files actually look like?

• parsing position files in ruby

  - by john

  I have a sample position file like below. 789754654 COLORA SOMETHING1 19370119FYY076 2342423234SS323423 742784897 COLORB SOMETHING2 20060722FYY076 2342342342SDFSD3423 I am interested in positions 54-61 (4th column). I want to change the date to be a different format. So final outcome will be: 789754654 COLORA SOMETHING1 01191937FYY076 2342423234SS323423 742784897 COLORB SOMETHING2 07222006FYY076 2342342342SDFSD3423 The columns are seperated by spaces not tabs. And the final file should have exact number of spaces as the original file....only thing changing should be the date format. How can I do this? I wrote a script but it will lose the original spaces and positioning will be messed up. file.each_line do |line| dob = line.split(" ") puts dob[3] #got the date. change its format 5.times { puts "**" } end Can anyone suggest a better strategy so that positioning in the original file remains the same?

• Executing ffmpeg from php running in apache

  - by foobar

  I was executing ffmpeg from php running inside apache. I used to get the error " error while loading shared libraries: libavdevice.so.52: cannot open shared object file: No such file or directory". It used to work perfectly if the php script was executed from the command prompt or ffpmeg was directly invoked from the command prompt. I followed the below steps to fix the apache error: Step 1: Check if the file “libavdevice.so.52? exists in the server using the following command. find / -name ‘libavdevice.so.*’ Step 2: You will get the directory in which the file “libavdevice.so.52? exists from the above command. Suppose the directory is “/usr/local/lib/” in this example. Step 3: You have to add the directory name in the file “/etc/ld.so.conf”. Step 4: Execute the command “ldconfig”. How did doing the above make a difference to apache?

• Control the MultipleOutputFormat files sub-path

  - by iCode

  I need to control the sub-path of the different different files being managed by MultipleOutputFormat based on the reducer key. I basically want to set the sub path of the file based on the key given to the reducer. I can changed the file name by overwrting the generateFileNameForKeyValue method of MultipleOutputFormatbut how can I also change the sub-path of these files? I mean with just overriding the generateFileNameForKeyValue, I get mySetJobConfigOutputPath/fileNameBasedKey1.dat /fileNameBasedKey2.dat /fileNameBasedKey3.dat ... but I want to make it to be organize files like below mySetJobConfigOutputPath/path0ConfiguredInsideReducerBasedOnKey/fileNameBasedKey1.dat /path1ConfiguredInsideReducerBasedOnKey/fileNameBasedKey2.dat /fileNameBasedKey3.dat /path2ConfiguredInsideReducerBasedOnKey/fileNameBasedKey8.dat as seen, the sub-path and the file name are both figured out by the key inside the reducer. I know how to configure the file name but was wondering if I can configure the sub-path of the each file under the mySetJobConfigOutputPath folder?

• Staticly linked libraries not running code inside to setup static variables.

  - by MJD

  In a c++ project I am working on, I have a simple c++ file that needs to run some code at the beginning of the progam execution. This file is linked into a static library, which is then linked into the main program. I have similar code in other files running fine, that looks something like: bool ____nonexistant_value = executeAction(); However, it does not work inside this file unless I make use of a function implemented in this file. It does work if the library is compilied as a shared library. I'd prefer to link this statically as the library is only a convience as the file is in a different directory.

• Hyperlinks in VS2008 Test Result Details

  - by Red XIII

  In case when resulting string in "Test Result Details" (TRD) is very long, the Visual Studio 2008 crashes. I fixed this by sending the result data into a file. There is a problem, however, because there isn't a simple way to open such file. Of course, I can manually open folder and then the file, but it isn't very efficient. Now, to the questions part. Is there a possibility to include in the "Error Message" part of TRD a hyperlink to a file? (something similar to what we can already find in the stack trace part) If not, is there any way to add such functionality (easy opening of a file) to TRD? If not, are there any ways to expand the default reporting of VS? Thanks for any help.

• rails eval code

  - by xpepermint

  Hey. I have to do a coll inside my model like this: import = Import.find(id) status = User.find(import.user_id).{XXX}.import(import.file.path) Notice a {XXX} which should be replaced by a dinamic variable of a submodel. Model User has_many groups, clients and products. In translation this would be status = User.find(import.user_id).groups.import(import.file.path) status = User.find(import.user_id).clients.import(import.file.path) status = User.find(import.user_id).products.import(import.file.path) I was thinking of import = Import.find(id) status = eval("User.find(#{import.user_id}).#{import.model}").import(import.file.path) but this gives me an error 'TypeError: can't convert nil into String'. Please tell me how would you fix that. Thx!

• Pushin each_line into array not working

  - by zettt

  Hi, I've got a weird issue with Ruby. I want to read data from a file and put the data then into an array. The weird thing is, it's working in another script which does basically, the same thing. quoteArray = [] quoteFile = File.new("quotes.txt", "r") or die "Unable to open file..." quoteFile.each_line { |line| quoteArray.push line } puts quoteArray[0] All I get out of this is an array with one element where the whole text file is in. What's wrong? Is it my machine? The text file? Any ideas? Thanks in advance

• Rendering HTML in rails without actually displaying it

  - by Kevin Whitaker

  Hello all, My current project requires me to assemble a .zip file containing HTML and text-only templates for a user to download, for importing into an email marketing program. I've inherited this project, and currently the code uses a "fake" model (that is a model that does not directly correlate to a database table), in which it stores the entire template in a string, using dynamic variables to populate certain areas. The "fake" model then has a method for creating a zip file. It seems to me that there has to be a better way to do this. I was wondering if there was a way to move the template into a .erb/haml file, and then write a method that would populate the file in preparation for being zipped up? Basically, is there a way to render an HTML and text file, without actually having to display them? Thanks for any help.

• PHP - Search array in array

  - by Anonymous2011

  I have tried googling for the past one hour straight now and tried many ways to search for an array, in an array. My objective is, to find a keyword in the URL, and the keywords are in a txt file. This is what i have so far - but doesn't work. $file = "keywords.txt"; $open = fopen($file,'r'); $data = fread($open,filesize($file)); $data = explode(" ",$data); $url = (!empty($_SERVER['HTTPS'])) ? "https://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'] : "http://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI']; $url = parse_url($url); //parse the URL into an array foreach($data as $d) { if(strstr($d,$url)) { echo "yes"; } } This works WITHOUT the text file, or array - but that's not what i want. I'd appreciate it if anyone can assist me.

• Rails - Rendering a Partial without having to use "_" in front of the filename?

  - by bluedevil2k

  How do I render a partial without having to supply the "_" in front of the file name? Is there a parameter I can call to not use it? This problem popped up using RABL and Backbone - using RABL requires me to have a file in my views like "index.json.rabl". But, when I use embed the JSON right on the page load (as is usual with Backbone), I'm required to call the file "index.json.rabl". These 2 files are the exact same thing, just required to have different names. I'm looking to use just 1 file, "index.json.rabl" and force the render() function to look for that file name, without the "".

• Lua not producing table of functions (IO API)

  - by ArtOfCode

  I'm working on a basic project in Lua. I've been trying to get data from files using the IO API (as defined here), but when I open a file and give it a handle, it doesn't seem to return a table of functions. The (erroneous bit of) code: local unread = fs.list("email/"..from.."/") local send = "" for _,file in ipairs(unread) do local handle = io.open(file,"r") local text = handle:read("*a") send = send .. text .. "\n" handle.close() fs.delete(file) end The fs you see on the first line is a professional filesystem wrapper round the IO API, not my work and perfectly error-free, so that's not the problem. However, when I try to read the file (handle:read()), it throws "attempt to index nil". Tracing it, it turns out that handle itself is nil. Any ideas?

• Changing find to echo

  - by waszak

  This is almost good find *.txt -print0 | xargs -0 rm -f And i want to have something like that echo *.txt ./zad3.sh | xargs -l rm -f First version is good because I can delete file with white spaces but I can't use my script to select file to delete. Second version I can select files but I can't delete file with white spaces. I want to find files with end on .txt and delete some of them. zad3.sh is a script wich is returning file name if i agree to delete it rm catch the name and delete it. It works only for file without white space and special characters. Second version is better but i cant put my script inside it. find *.txt -print0| xargs -0 ./zad3.sh |xargs rm -f it works almost but i cant pass arg to rm and part of my code Thx

• C++ how to make typedefs globally visible

  - by user231536

  I have a typedef typedef unsigned int my_type; used in a file. I would like to make it visible across all my files, without putting it in a header file included by everything. I don't want to go the header file route because as it stands this will be the only declaration in the header file (and it seems unnecessary to add a file just for this). Is there a way to do this? If instead I had: typedef X my_type; where X was a class, would I need to include X.h everywhere and have the typedef at the end of X.h ?

• How to run a module

  - by Jimmy

  I have a module file containing the following functions: def replace(filename): match = re.sub(r'[^\s^\w]risk', 'risk', filename) return match def count_words(newstring): from collections import defaultdict word_dict=defaultdict(int) for line in newstring: words=line.lower().split() for word in words: word_dict[word]+=1 for word in word_dict: if'risk'==word: return word, word_dict[word] when I do this in IDLE: >>> mylist = open('C:\\Users\\ahn_133\\Desktop\\Python Project\\test10.txt').read() >>> newstrings=replace(mylist) ### This works fine. >>> newone=count_words(newstrings) ### This leads to the following error.

• Docmd.TransferText question

  - by every_answer_gets_a_point

  b'h i will be programmatically importing a text file into a table. i have saved the import steps. i will use this: DoCmd.TransferText(TransferType, SpecificationName, TableName, FileName, HasFieldNames, HTMLTableName, CodePage) to do the import. this is what SpecificationName means: Specification Name The specification name for the set of options that determines how a text file is imported, exported, or linked. For a fixed-width text file, you must either specify a specification name or use a schema.ini file, which should be stored in the same directory as the imported, linked, or exported text file. i do need a specific specification; however i do not know how to specify one. when i manually imported a table, i did save the specifications for my import, however i do not know how to call this in the TransferText. does anyone know how to specify SpecificationName ?
