• Search for odt files without indexing

  - by josinalvo

  I am looking for: a way to search inside odt files (i.e. search for contents, not name) that does not require any kind of indexing that is graphical and very user-friendly (for a relatively old person, who does not like computers much) I know that it is possible to have 1) and 2): for x in `find . -iname '*odt'`; do odt2txt $x | grep Query; done works well enough, and it's pretty fast. But I wonder if there is already a good solution that does this with a GUI (or can be adapted to do this easily)

• Convert Microsoft Word documents (.doc/x) into HTML files

  - by danie7L T

  Does anybody knows of a good application to get it done quickly and efficiently ? I bought Word Cleaner but the results are merely sufficient and I need go over all the generated html files to clean tons of useless injected tags like <strongH</strong<strongell</strong<strongo </strong<emWor</em<emld</em Most of the articles displayed on a website I manage are based on documents written on MS Word by people how has little idea of what are margins for or ordered/unordered lists, foot/end notes etc and I cannot make them use something else. Does anyone has a tip to help me handle those pages more efficiently than going over them to correct and apply my CSS style ? NB: Just for the record, using "Save as HTML DOC" in Word is faaar worst than Word cleaner

• Can't load Wordpress static files on home network

  - by Tosho

  I've just installed Wordpress 3.5 on my laptop (LAMP on Ubuntu 12.10) and when I'm trying to access the site from my phone but it doesn't load static files (css and images). I tried with Opera Mobile Emulator on my laptop and it works perfectly. I also have another Drupal site on my localhost which I can load from my phone without any issues. Both directories have chmod 777 permissions. What can cause that? Just tried to open the site from my sister's laptop but it except static file I can't access any post or page.

• Please help with samba, can't access files from other computer

  - by user254074

  Maybe I am missing something but all I want to do is be able to access and transfer files from one folder on my main computer to my htpc. Both computers are running Ubuntu 14.04. I followed the instructions on this video but I am not sure if I need to do something on the HTPC to access my Movie folder. I went into nautilus then Browse Network Windows Network Workgroup but I get an error and it won't let me access it. Is there something I am doing wrong?

• Automatically delete files after they expire

  - by Auxiliary

  I've got this idea for some time and I was wondering if anyone has seen such a feature/app in any operating system and if you haven't, what do you think about it. Where do you think I should begin? The idea is simple. I think we all have those files that are made and probably used for a few days and then are left on our disk and we never delete them or even check to see if we need them again. It'd be cool if you could right click on a file and click on "Expire in.. 3 days" for example. And the file gets deleted after 3 days. I have a great need for this and maybe some people will find it useful. I was thinking of writing a script and use the Nautilus Action project in GNOME for a start.

• Synchronizing (updating) published files

  - by MucMug

  How can I update a published file and maintain the same URL? After saving an update of a published file on my desktop, it will automatically "synchronise" with the corresponding files at UbuntuOne (and it does). Problem is that the "new file", actually the updated file with the same name, is no longer published. Pressing the publish button results is a new URL. I now have to mail new URL's and change embedded links, as old URL will result in a failure to find the updated file (or indeed any file). I am not sure if it is a bug or a design flaw (maybe intentional?), but it seems strange to me.

• Why touching "d_name" makes calls to readdir() fail?

  - by Sarah Mani

  Hi, I'm trying to write a little helper for Windows which eventually will accept a file extension as an argument and return the number of files of that kind in the current directory. To do so, I'm reading the file entries in the directories and after getting the extension I'd like to convert it to lowercase to compare it with the yet-to-add specified argument. When converting the extension to lowercase I found that touching even a duplicate string of the d_name variable will cause a strange behaviour, like no more calls to readdir are called. Here is the code I'm using right now (the commented code is preliminary) and outputs for a given directory: #include <ctype.h> #include <dirent.h> #include <stdio.h> #include <string.h> char * strrch(char *string, size_t elements, char character) { char *reverse = string + elements; while (--reverse != string) if (*reverse == character) return reverse; return NULL; } void test(char *string) { // Even being a duplicate will make it fail: char *str = strdup(string); printf("Strings: %s %s\n", string, str); *str = 'a'; printf("Strings: %s %s\n", string, str); //unsigned short int i = 0; //for (; str[i] != '\0', str++; i++) // str[i] = tolower((unsigned char) str[i]); //puts(str); } int main(int argc, char **argv) { DIR *directory; struct dirent *element; if (directory = opendir(".")) { while (element = readdir(directory)) test(strrch(element->d_name, element->d_namlen, '.')); closedir(directory); puts(NULL); } else puts("Couldn't open the directory.\n"); } Output without modifying the duplicate (modification and the second printf call commented): Strings: (null) (null) Strings: . . Strings: .exe .exe Strings: .pdf .pdf Strings: .c .c Strings: .ini .ini Strings: .pdf .pdf Strings: .pdf .pdf Strings: .pdf .pdf Strings: .flac .flac Strings: .FLAC .FLAC Strings: .lnk .lnk Strings: .URL .URL Output of the same directory (with the code above, with the 2 printfs): Strings: (null) (null) Is there anything wrong? Is it a compiler issue? I'm using GCC 4.4.3 in Windows (MinGW) right now. Thank you very much for your help. By the way, is there any other way to work with files and directories in a Windows environment not using the POSIX functions?

• migrating from Prototype to jQuery in Rails, having trouble with duplicate get request

  - by aressidi

  I'm in the process of migrating from Prototype to jQuery and moving all JS outside of the view files. All is going fairly well with one exception. Here's what I'm trying to do, and the problem I'm having. I have a diary where users can update records in-line in the page like so: user clicks 'edit' link to edit an entry in the diary a get request is performed via jQuery and an edit form is displayed allowing the user to modify the record user updates the record, the form disappears and the updated record is shown in place of the form All of that works so far. The problem arises when: user updates a record user clicks 'edit' to update another record in this case, the edit form is shown twice! In firebug I get a status code 200 when the form shows, and then moments later, another edit form shows again with a status code of 304 I only want the form to show once, not twice. The form shows twice only after I update a record, otherwise everything works fine. Here's the code, any ideas? I think this might have to do with the fact that in food_item_update.js I call the editDiaryEntry() after a record is updated, but if I don't call that function and try and update the record after it's been modified, then it just spits up the .js.erb response on the screen. That's also why I have the editDiaryEntry() in the add_food.js.erb file. Any help would be greatly appreciated. diary.js jQuery(document).ready(function() { postFoodEntry(); editDiaryEntry(); initDatePicker(); }); function postFoodEntry() { jQuery('form#add_entry').submit(function(e) { e.preventDefault(); jQuery.post(this.action, jQuery(this).serialize(), null, "script"); // return this }); } function editDiaryEntry() { jQuery('.edit_link').click(function(e) { e.preventDefault(); // This should look to see if one version of this is open... if (jQuery('#edit_container_' + this.id).length == 0 ) { jQuery.get('/diary/entry/edit', {id: this.id}, null, "script"); } }); } function closeEdit () { jQuery('.close_edit').click(function(e) { e.preventDefault(); jQuery('.entry_edit_container').remove(); jQuery("#entry_" + this.id).show(); }); } function updateDiaryEntry() { jQuery('.edit_entry_form').submit(function(e) { e.preventDefault(); jQuery.post(this.action, $(this).serialize(), null, "script"); }); } function initDatePicker() { jQuery("#date, #edit_date").datepicker(); }; add_food.js.erb jQuery("#entry_alert").show(); jQuery('#add_entry')[ 0 ].reset(); jQuery('#diary_entries').html("<%= escape_javascript(render :partial => 'members/diary/diary_entries', :object => @diary, :locals => {:record_counter => 0, :date_header => 0, :edit_mode => @diary_edit}, :layout => false ) %>"); jQuery('#entry_alert').html("<%= escape_javascript(render :partial => 'members/diary/entry_alert', :locals => {:type => @type, :message => @alert_message}) %>"); jQuery('#entry_alert').show(); setTimeout(function() { jQuery('#entry_alert').fadeOut('slow'); }, 5000); editDiaryEntry(); food_item_edit.js.erb jQuery("#entry_<%= @entry.id %>").hide(); jQuery("#entry_<%= @entry.id %>").after("<%= escape_javascript(render :partial => 'members/diary/food_item_edit', :locals => {:user_food_profile => @entry}) %>"); closeEdit(); updateDiaryEntry(); initDatePicker(); food_item_update.js jQuery("#entry_<%= @entry.id %>").replaceWith("<%= escape_javascript(render :partial => 'members/diary/food_item', :locals => {:entry => @entry, :total_calories => 0}) %>"); jQuery('.entry_edit_container').remove(); editDiaryEntry();

• ant ftp doesn't download files in subdirectories

  - by Kristof Neirynck

  Hello, I'm trying to download files in subdirectories from an ftp server with ant. The exact set of files is known. Some of them are in subdirectories. Ant only seems to download the ones in the root directory. It does work if I download all files without listing them. The first ftp action should do the exact same thing as the second. Instead it complains about "Hidden files" and seems to prefix the paths with "\\". Does anyone know what's wrong here? Is this a bug in commons-net? build.xml <?xml version="1.0" encoding="utf-8"?> <project name="example" default="example" basedir="."> <taskdef name="ftp" classname="org.apache.tools.ant.taskdefs.optional.net.FTP" /> <target name="example"> <!-- 2 files retrieved --> <ftp action="get" verbose="true" server="localhost" userid="example" password="example"> <fileset dir="downloads" casesensitive="false" includes="root1.txt,root2.txt,a/a.txt,a/b/ab.txt,c/c.txt" /> </ftp> <!-- 5 files retrieved --> <ftp action="get" verbose="true" server="localhost" userid="example" password="example"> <fileset dir="downloads" casesensitive="false" includes="**/*" /> </ftp> </target> </project> run_ant.bat @ECHO OFF PUSHD %~dp0 SET CLASSPATH= SET ANT_HOME=C:\apache-ant-1.8.0 SET ant=%ANT_HOME%\bin\ant.bat SET antoptions=-nouserlib -noclasspath -d SET ftpjars=^ -lib lib\jakarta-oro-2.0.8.jar ^ -lib lib\commons-net-2.0.jar CALL %ant% %antoptions% %ftpjars% > output.txt POPD output.txt Unable to locate tools.jar.

• Using the HTML5 &lt;input type=&quot;file&quot; multiple=&quot;multiple&quot;&gt; Tag in ASP.NET

  - by Rick Strahl

  Per HTML5 spec the <input type="file" /> tag allows for multiple files to be picked from a single File upload button. This is actually a very subtle change that's very useful as it makes it much easier to send multiple files to the server without using complex uploader controls. Please understand though, that even though you can send multiple files using the <input type="file" /> tag, the process of how those files are sent hasn't really changed - there's still no progress information or other hooks that allow you to automatically make for a nicer upload experience without additional libraries or code. For that you will still need some sort of library (I'll post an example in my next blog post using plUpload). All the new features allow for is to make it easier to select multiple images from disk in one operation. Where you might have required many file upload controls before to upload several files, one File control can potentially do the job. How it works To create a file input box that allows with multiple file support you can simply do:<form method="post" enctype="multipart/form-data"> <label>Upload Images:</label> <input type="file" multiple="multiple" name="File1" id="File1" accept="image/*" /> <hr /> <input type="submit" id="btnUpload" value="Upload Images" /> </form> Now when the file open dialog pops up - depending on the browser and whether the browser supports it - you can pick multiple files. Here I'm using Firefox using the thumbnail preview I can easily pick images to upload on a form: Note that I can select multiple images in the dialog all of which get stored in the file textbox. The UI for this can be different in some browsers. For example Chrome displays 3 files selected as text next to the Browse… button when I choose three rather than showing any files in the textbox. Most other browsers display the standard file input box and display the multiple filenames as a comma delimited list in the textbox. Note that you can also specify the accept attribute in the <input> tag, which specifies a mime-type to specify what type of content to allow.Here I'm only allowing images (image/*) and the browser complies by just showing me image files to display. Likewise I could use text/* for all text formats registered on the machine or text/xml to only show XML files (which would include xml,xst,xsd etc.). Capturing Files on the Server with ASP.NET When you upload files to an ASP.NET server there are a couple of things to be aware of. When multiple files are uploaded from a single file control, they are assigned the same name. In other words if I select 3 files to upload on the File1 control shown above I get three file form variables named File1. This means I can't easily retrieve files by their name:HttpPostedFileBase file = Request.Files["File1"]; because there will be multiple files for a given name. The above only selects the first file. Instead you can only reliably retrieve files by their index. Below is an example I use in app to capture a number of images uploaded and store them into a database using a business object and EF 4.2.for (int i = 0; i < Request.Files.Count; i++) { HttpPostedFileBase file = Request.Files[i]; if (file.ContentLength == 0) continue; if (file.ContentLength > App.Configuration.MaxImageUploadSize) { ErrorDisplay.ShowError("File " + file.FileName + " is too large. Max upload size is: " + App.Configuration.MaxImageUploadSize); return View("UploadClassic",model); } var image = new ClassifiedsBusiness.Image(); var ms = new MemoryStream(16498); file.InputStream.CopyTo(ms); image.Entered = DateTime.Now; image.EntryId = model.Entry.Id; image.ContentType = "image/jpeg"; image.ImageData = ms.ToArray(); ms.Seek(0, SeekOrigin.Begin); // resize image if necessary and turn into jpeg Bitmap bmp = Imaging.ResizeImage(ms.ToArray(), App.Configuration.MaxImageWidth, App.Configuration.MaxImageHeight); ms.Close(); ms = new MemoryStream(); bmp.Save(ms,ImageFormat.Jpeg); image.ImageData = ms.ToArray(); bmp.Dispose(); ms.Close(); model.Entry.Images.Add(image); } This works great and also allows you to capture input from multiple input controls if you are dealing with browsers that don't support multiple file selections in the file upload control. The important thing here is that I iterate over the files by index, rather than using a foreach loop over the Request.Files collection. The files collection returns key name strings, rather than the actual files (who thought that was good idea at Microsoft?), and so that isn't going to work since you end up getting multiple keys with the same name. Instead a plain for loop has to be used to loop over all files. Another Option in ASP.NET MVC If you're using ASP.NET MVC you can use the code above as well, but you have yet another option to capture multiple uploaded files by using a parameter for your post action method.public ActionResult Save(HttpPostedFileBase[] file1) { foreach (var file in file1) { if (file.ContentLength < 0) continue; // do something with the file }} Note that in order for this to work you have to specify each posted file variable individually in the parameter list. This works great if you have a single file upload to deal with. You can also pass this in addition to your main model to separate out a ViewModel and a set of uploaded files:public ActionResult Edit(EntryViewModel model,HttpPostedFileBase[] uploadedFile) You can also make the uploaded files part of the ViewModel itself - just make sure you use the appropriate naming for the variable name in the HTML document (since there's Html.FileFor() extension). Browser Support You knew this was coming, right? The feature is really nice, but unfortunately not supported universally yet. Once again Internet Explorer is the problem: No shipping version of Internet Explorer supports multiple file uploads. IE10 supposedly will, but even IE9 does not. All other major browsers - Chrome, Firefox, Safari and Opera - support multi-file uploads in their latest versions. So how can you handle this? If you need to provide multiple file uploads you can simply add multiple file selection boxes and let people either select multiple files with a single upload file box or use multiples. Alternately you can do some browser detection and if IE is used simply show the extra file upload boxes. It's not ideal, but either one of these approaches makes life easier for folks that use a decent browser and leaves you with a functional interface for those that don't. Here's a UI I recently built as an alternate uploader with multiple file upload buttons: I say this is my 'alternate' uploader - for my primary uploader I continue to use an add-in solution. Specifically I use plUpload and I'll discuss how that's implemented in my next post. Although I think that plUpload (and many of the other packaged JavaScript upload solutions) are a better choice especially for large uploads, for simple one file uploads input boxes work well enough. The advantage of this solution is that it's very easy to handle on the server side. Any of the JavaScript controls require special handling for uploads which I'll also discuss in my next post.© Rick Strahl, West Wind Technologies, 2005-2012Posted in HTML5  ASP.NET  MVC   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

• Delphi - threads and FindFirst function

  - by radu-barbu

  Hi, I'm encountering a big problem when i'm trying to make a recursive search function inside a thread (using delphi 7) bellow is the code: TParcFicDir = class(TThread) private several variables.. protected procedure Execute; override; public constructor Create(CreateSuspended: Boolean); constructor TParcFicDir.Create(CreateSuspended: Boolean); begin inherited Create(CreateSuspended); end; procedure TParcFicDir.Execute; begin try FindFiles(FStartDir,FMask);//'c:\' and '*.*' except on e:Exception do end; end; procedure TParcFicDir.FindFiles(StartDir, FileMask: string); var wTmp : string; f:TextFile; wTempSR:TSearchRec; function Search(StartDir, FileMask: string): string; var SR : TSearchRec; IsFound : Boolean; files : integer; dirs : integer; t : string; begin try files := 0; dirs := 0; if StartDir[length(StartDir)] <> '\' then StartDir := StartDir + '\'; try IsFound := (FindFirst(StartDir + '*.*', faAnyFile, SR) = 0);// here the thread gets interrupted except on e: Exception do end; while IsFound do begin if (SR.Name <> '.') and (SR.Name <> '..') then if ((SR.Attr and faDirectory) <> 0) then if FScanDirs then begin inc(dirs); t := Search(StartDir + SR.Name, FileMask); try files := files + strtoint(copy((t), 0, pos('#', t) - 1));//old code, don't take on calcul; Delete(t, 1, pos('#', t)); dirs := dirs + strtoint(t); except on e: Exception do end; begin t := StartDir + SR.Name; wTmp := t; wtmp := ''; Inc(FDirNo); writeln(f,t); inc(filno); end; end else if ScanFiles then begin inc(filno); inc(files); end; IsFound := FindNext(SR) = 0; end; Result := IntToStr(files) + '#' + IntToStr(dirs); sysutils.FindClose(SR); except on e: Exception do end; end; begin filno := 0; try try if trim(FPathFileTmp)<>'' then AssignFile(f, FPathFileTmp+'Temp.bak') else AssignFile(f,ExtractFileDir(GetDllName)+'\Temp.bak'); Rewrite(f); Search(StartDir, FileMask); if StartDir[length(StartDir)] = '\' then delete(StartDir, length(StartDir), 1); wTmp := StartDir; wTmp := ''; if FindFirst(StartDir, faDirectory, wTempSR) = 0 then writeln(f); writeln(f); CloseFile(f); except on e: Exception do end; finally end; end; ok, probably the code is a little messed up, but i don't understand why the thread ends at 'findfirst' part....i googled it, no results. any help will be appreciated!

• C# file write permission issue under "Program Files" folder

  - by George2

  Hello everyone, I am using inno setup to make a installation package for my application, and my application is written by C# + .Net 2.0 + VSTS 2008. Inno setup = http://www.jrsoftware.org/isinfo.php and I install my application under Program Files/Foo folder (Foo is my application name). My application is targeting to Windows Vista. The issue I found is my program cannot write to the folder Program Files/Foo. And I need the permission of write to this folder in order to save some configuration files. The strange thing I notice is the folder Program Files/Foo is marked as readonly and I have checked all folders under Program Files are marked with read only, such as Office. My questions are, Why all folders are marked as read only under Program Files? It means we should not write to individual application folders under Program Files? If not, where should we write information to disk like user last selected configuration information of an individual application? If we could write to individual application folders under Program Files, what is the solution? I do not want my application to Run As administrator to solve this issue, and if there are solution to write to this folder, I want to require minimal permission if possible. thanks in advance, George

• Problems importing WAR files in Eclipse?

  - by CitadelCSAlum

  I was unfortunately forced to result to uploading a WAR file as my backup for a web application I am working on. Luckily I have the most recent WAR file available. I am using Eclipse IDE and am using the Web Tools plugin for all the J2EE work that I am doing with the Dynamic Web Application Project. When I imported my WAR file, and ran it on a local server, everything works fine. The problem I a ran into is that in the Java Resources/src folder that all my packages and .java files were now only consists of all the same packages, but they are empty. I checked to see if I could find the files and I found the .class files in an "Imported files" folder that is not accessible in the Eclipse Project Explorer. I believe that I need to do some type of build or something so that my .java files are available for me, but unfortunately this is one area where I lack. One thing I would also like to know is, one way or the other, am I able to obtain the .java source code files if I have access to the .class files? Also, I would like to configure this environment as it was before where my Java Resources:src folder contaiend the packages and .java files.

• Access/Download server files, not in site root, with PHP

  - by user271619

  Usually I save documents (images, mpegs, excel, word docs, etc...) for my friends or family on my website's root, inside a directory called /files/ or something similar. Nothing too uncommon. But, I have been playing with user session control, and allowing users to upload files to the dedicated /files/ directory. (the file names are saved in a db, with that user's ID) But, that means other people could try to guess and locate other people's files. I do randomize the file names, upon upload. And I stop the apache from displaying the /files/ directory content. However, I'd like to start saving the files outside of the website's root. This way it can't be accessible via the browser. I don't have any code to show, but I didn't want to even start on this endeavor if it's not able to be accomplished. I did find this snippet that shows how to display an image, from outside your website root: $file = $_GET['file']; $fileDir = '/path/to/files/'; if (file_exists($fileDir . $file)) { // Note: You should probably do some more checks // on the filetype, size, etc. $contents = file_get_contents($fileDir . $file); // Note: You should probably implement some kind // of check on filetype header('Content-type: image/jpeg'); echo $contents; } ? Maybe I can use this for any file type, but has anyone heard of a better way to allow users (logged in) to access their files from online, but not letting other users has similar access?

• Visual Studio Linked Files Directory Structure

  - by jeffn825

  I have two versions of a project. One for Silverlight and one for .NET. The SL project has the vast majority of the code base in it. I want to globally add all files from the SL project into the .NET version as linked files. I've managed to do so successfully like this in the csproj file for the .NET version: <Compile Include="..\MyProj.Common.SL\**\*.cs" Exclude="..\MyProj.Common\Properties\**"> Unfortunately, this adds all the files right to the root of my project... so I end up with a long unreadable list of linked files in the .NET project. I really really really don't want to have to maintain an entire duplicate directory structure by hand and deal with directory name changes and file name changes and whatnot. So, is there any way to have Visual Studio preserve the directory structure when adding linked files in the wildcard manner above? Or is there at least a way of making it group all the linked files together under a directory in the .NET project like MyProj.Common.SL.Links? The very closest I've come is to set the <Visible>false</Visible> under the <Compile> tag, which effectively removes the long unreadable list of 300+ files....but unfortunately this screws up Resharper, which no longer sees those files as valid and it goes crazy on all the projects that reference the .NET project. If I could figure out a way of making Resharper not get all messed up, that would be an acceptable solution too... Any suggestions? Thanks.

• Programatically rebuild .exd-files when loading VBA

  - by aspartame

  Hi, After updating Microsoft Office 2007 to Office 2010 some custom VBA scripts embedded in our software failed to compile with the following error message: Object library invalid or contains references to object definitions that could not be found. As far as I know, this error is a result of a security update from Microsoft (Microsoft Security Advisory 960715). When adding ActiveX-controls to VBA scripts, information about the controls are stored in cache files on the local hard drive (.exd-files). The security update modified some of these controls, but the .exd-files were not automatically updated. When the VBA scripts try to load the old versions of the controls stored in the cached files, the error occurs. These cache-files must be removed from the hard drive in order for the controls to load successfully (which will create new, updated .exd-files automatically). What I would like to do is to programatically (using Visual C++) remove the outdated .exd-files when our software loads. When opening a VBA project using CApcProject::ApcProject.Open I set the following flag:axProjectThrowAwayCompiledState. TestHR(ApcProject.Open(pHost, (MSAPC::AxProjectFlag) (MSAPC::axProjectNormal | MSAPC::axProjectThrowAwayCompiledState))); According to the documentation, this flag should cause the VBA project to be recompiled and the temporary files to be deleted and rebuilt. I've also tried to update the checksum of the host application type library which should have the same effect. However none of these fixes seem to do the job and I'm running out of ideas. Help is very much appreciated!

• IIS 6+ASP.NET - many temp files generated

  - by moshe_ravid

  I have a ASP.NET + some .NET web-services running on IIS 6 (win 2003 server). The issue is that IIS is generating a lot (!) of files in "c:\WINDOWS\Temp" directory. a lot of files means thousands of files, which get to more than 3G of size so far. The files are generated by this command: C:\WINDOWS\SysWOW64\inetsrv "C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\csc.exe" /t:library /utf8output /R:"C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\vfagt\113819dd\db0d5802\assembly\dl3\fedc6ef1\006e24d8_3bc9ca01\VfAgentWService.DLL" /R:"C:\WINDOWS\assembly\GAC_MSIL\System.Web.Services\2.0.0.0__b03f5f7f11d50a3a\System.Web.Services.dll" /R:"C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\mscorlib.dll" /R:"C:\WINDOWS\assembly\GAC_MSIL\System.Xml\2.0.0.0__b77a5c561934e089\System.Xml.dll" /R:"C:\WINDOWS\assembly\GAC_MSIL\System\2.0.0.0__b77a5c561934e089\System.dll" /out:"C:\WINDOWS\TEMP\9i_i2bmg.dll" /debug- /optimize+ /nostdlib /D:_DYNAMIC_XMLSERIALIZER_COMPILATION "C:\WINDOWS\TEMP\9i_i2bmg.0.cs" The files in the temp directory are pairs of *.out & *.err, where the *.err file is zero size, and the *.out file contains the compilation output messages. What is causing IIS to generate so many files? How can I prevent it? UPDATE: The problem is that the command i described above (csc.exe) is being executed many (many) times, causing the .out & .err to be generated so many times, until it consumes the disk space. So - my question is: what is causing this command to run so many times? (i don't have that many .aspx & .asmx files in my web app). Thanks, Moe

• Find files on a remote server

  - by Peter Kelly

  I have a web-service that resides on serverA. The webservice will be responsible for finding files of a certain type in a virtual directory on serverB and then returning the full URL to the files. I have the service working if the files are located on the same machine - this is straight-forward enough. My question is what is the best way to find all files of a certain type (say *.xml) in all directories below a known virtual directory on a remote server? So for example, the webservice is on http://ServerA/service.asmx and the virtual directory is located at http://serverB/virtualdirectory So in this code, obviously the DirectoryInfo will not take a path to the remote server - how do I access this so I can find the files it contains? How do I then get the full URL to a file found on that remote server? DirectoryInfo updateDirectory = new DirectoryInfo(path); FileInfo[] files = updateDirectory.GetFiles("*.xml", SearchOption.AllDirectories); foreach (FileInfo fileInfo in files) { // Get URL to the file } I cannot have the files and the service on the same server - IT decision that is out of my hands. Thanks!

• jQuery recursive function to upload many files while giving the user some feedback

  - by checcco

  Hi guys, I'm trying to write a jQuery function to let users upload many files at once. Here's the function I thought to give the user some feedback about the upload process progress. function uploadFiles(numbersOfFiles, start) { $("#info").html(start + " files uploaded"); $.post('upload.php', { start: start }, function (data) { start += 5; if (start < numbersOfFiles) { $("#info").html(start + " files uploaded"); uploadFiles(numbersOfFiles, start); } else { $("#info").html("All files have been uploaded"); } }); } The function calls a php script to upload 5 files, then if there are more files to upload it calls the script again. The whole process works. I've tried it with 100 files. The only thing that doesn't work is the #info div updating. The div get updated the first time and then again only to show "All files have been uploaded". So there's no feedback for the user about the uploading process. I can't understand why... Any help?

• Template inheritence c++

• PHP sessions and class members.

  - by JDW

  Ok, messing about with classes in PHP and can't get it to work the way I'm used to as a C++/Java-guy. In the "_init" funtion, if I run a query at the "// query works here" line", everythong works, but in the "getUserID" function, all that happens is said warning... "getUserID" gets called from login.php (they are in the same dir): login.php <?php include_once 'sitehandler.php'; include_once 'dbhandler.php'; session_start(); #TODO: Safer input handling $t_userName = $_POST["name"]; $t_userId = $_SESSION['handler']['db']->getUserID($t_userName); if ($t_userId != -1) { $_SESSION['user']['name'] = $t_userName; $_SESSION['user']['id'] = $t_userId; } //error_log("user: " . $_SESSION['user']['name'] . ", id: ". $_SESSION['user']['id']); header("Location: " . $_SERVER["HTTP_REFERER"]); ? dbhandler.php <?php include_once 'handler.php'; class DBHandler extends HandlerAbstract { private $m_handle; function __construct() { parent::__construct(); } public function test() { #TODO: isdir liquibase #TODO: isfile liquibase-195/liquibase + .bat + execrights $this->m_isTested = true; } public function _init() { if (!$this->isTested()) $this->test(); if (!file_exists('files/data.db')) { #TODO: How to to if host is Windows based? exec('./files/liquibase-1.9.5/liquibase --driver=org.sqlite.JDBC --changeLogFile=files/data_db.xml --url=jdbc:sqlite:files/data.db update'); #TODO: quit if not success } #TODO: Set with default data try { $this->m_handle = new SQLite3('files/data.db'); } catch (Exception $e) { die("<hr />" . $e->getMessage() .

• Given a trace of packets, how would you group them into flows?

  - by zxcvbnm

  I've tried it these ways so far: 1) Make a hash with the source IP/port and destination IP/port as keys. Each position in the hash is a list of packets. The hash is then saved in a file, with each flow separated by some special characters/line. Problem: Not enough memory for large traces. 2) Make a hash with the same key as above, but only keep in memory the file handles. Each packet is then put into the hash[key] that points to the right file. Problems: Too many flows/files (~200k) and it might run out of memory as well. 3) Hash the source IP/port and destination IP/port, then put the info inside a file. The difference between 2 and 3 is that here the files are opened and closed for each operation, so I don't have to worry about running out of memory because I opened too many at the same time. Problems: WAY too slow, same number of files as 2 so also impractical. 4) Make a hash of the source IP/port pairs and then iterate over the whole trace for each flow. Take the packets that are part of that flow and place them into the output file. Problem: Suppose I have a 60 MB trace that has 200k flows. This way, I would process, say, a 60 MB file 200k times. Maybe removing the packets as I iterate would make it not so painful, but so far I'm not sure this would be a good solution. 5) Split them by IP source/destination and then create a single file for each one, separating the flows by special characters. Still too many files (+50k). Right now I'm using Ruby to do it, which might've been a bad idea, I guess. Currently I've filtered the traces with tshark so that they only have relevant info, so I can't really make them any smaller. I thought about loading everything in memory as described in 1) using C#/Java/C++, but I was wondering if there wouldn't be a better approach here, especially since I might also run out of memory later on even with a more efficient language if I have to use larger traces. In summary, the problem I'm facing is that I either have too many files or that I run out of memory. I've also tried searching for some tool to filter the info, but I don't think there is one. The ones I've found only return some statistics and wouldn't scan for every flow as I need.

• What is the right way to process inconsistent data files?

  - by Tahabi

  I'm working at a company that uses Excel files to store product data, specifically, test results from products before they are shipped out. There are a few thousand spreadsheets with anywhere from 50-100 relevant data points per file. Over the years, the schema for the spreadsheets has changed significantly, but not unidirectionally - in the sense that, changes often get reverted and then re-added in the space of a few dozen to few hundred files. My project is to convert about 8000 of these spreadsheets into a database that can be queried. I'm using MongoDB to deal with the inconsistency in the data, and Python. My question is, what is the "right" or canonical way to deal with the huge variance in my source files? I've written a data structure which stores the data I want for the latest template, which will be the final template used going forward, but that only helps for a few hundred files historically. Brute-forcing a solution would mean writing similar data structures for each version/template - which means potentially writing hundreds of schemas with dozens of fields each. This seems very inefficient, especially when sometimes a change in the template is as little as moving a single line of data one row down or splitting what used to be one data field into two data fields. A slightly more elegant solution I have in mind would be writing schemas for all the variants I can find for pre-defined groups in the source files, and then writing a function to match a particular series of files with a series of variants that matches that set of files. This is because, more often that not, most of the file will remain consistent over a long period, only marred by one or two errant sections, but inside the period, which section is inconsistent, is inconsistent. For example, say a file has four sections with three data fields, which is represented by four Python dictionaries with three keys each. For files 7000-7250, sections 1-3 will be consistent, but section 4 will be shifted one row down. For files 7251-7500, 1-3 are consistent, section 4 is one row down, but a section five appears. For files 7501-7635, sections 1 and 3 will be consistent, but section 2 will have five data fields instead of three, section five disappears, and section 4 is still shifted down one row. For files 7636-7800, section 1 is consistent, section 4 gets shifted back up, section 2 returns to three cells, but section 3 is removed entirely. Files 7800-8000 have everything in order. The proposed function would take the file number and match it to a dictionary representing the data mappings for different variants of each section. For example, a section_four_variants dictionary might have two members, one for the shifted-down version, and one for the normal version, a section_two_variants might have three and five field members, etc. The script would then read the matchings, load the correct mapping, extract the data, and insert it into the database. Is this an accepted/right way to go about solving this problem? Should I structure things differently? I don't know what to search Google for either to see what other solutions might be, though I believe the problem lies in the domain of ETL processing. I also have no formal CS training aside from what I've taught myself over the years. If this is not the right forum for this question, please tell me where to move it, if at all. Any help is most appreciated. Thank you.

• IIS logs show sc-win32-status=64 but only through some networks

  - by wweicker

  I have an ASP.NET application running on a client server (W2k3, IIS6, .NET 2.0). FWIW, this is a Test instance, it hasn't been moved into Production yet. So it is not running under SSL, load balancing, etc. When I access one of the pages on their server from our office, the page gets hit once. Inspecting the IIS logs (c:WINDOWS\system32\LogFiles\W3SVC1) show a GET for that page, then I push a button on the page and the log file shows a POST. This seems to be working fine so far. Now when I remote into the client's network and access the page from one of their local machines, the log file shows a GET, then I push the button on the page and the log shows two POSTs at the same second. The first one shows status (sc-status, sc-substatus, sc-win32-status) 200 0 64, the second shows 200 0 0. In the log file, both POSTs are identical. Basically the log looks like this (except I masked some of the data): #Fields: date time s-ip cs-method cs-uri-stem cs-uri-query s-port cs-username c-ip cs(User-Agent) sc-status sc-substatus sc-win32-status 2009-08-11 20:19:32 x.x.x.x GET /File.aspx - 80 - y.y.y.y Mozilla/4.0+(compatible;+MSIE+8.0;+Windows+NT+6.0;+WOW64;+Trident/4.0;+SLCC1;+.NET+CLR+2.0.50727;+.NET+CLR+3.5.21022;+.NET+CLR+3.5.30729;+.NET+CLR+3.0.30618;+MDDR;+OfficeLiveConnector.1.4;+OfficeLivePatch.0.0) 200 0 0 2009-08-11 20:19:45 x.x.x.x POST /File.aspx - 80 - y.y.y.y Mozilla/4.0+(compatible;+MSIE+8.0;+Windows+NT+6.0;+WOW64;+Trident/4.0;+SLCC1;+.NET+CLR+2.0.50727;+.NET+CLR+3.5.21022;+.NET+CLR+3.5.30729;+.NET+CLR+3.0.30618;+MDDR;+OfficeLiveConnector.1.4;+OfficeLivePatch.0.0) 200 0 64 2009-08-11 20:19:45 x.x.x.x POST /File.aspx - 80 - y.y.y.y Mozilla/4.0+(compatible;+MSIE+8.0;+Windows+NT+6.0;+WOW64;+Trident/4.0;+SLCC1;+.NET+CLR+2.0.50727;+.NET+CLR+3.5.21022;+.NET+CLR+3.5.30729;+.NET+CLR+3.0.30618;+MDDR;+OfficeLiveConnector.1.4;+OfficeLivePatch.0.0) 200 0 0 The problem is, the page is getting hit twice. The database performs an operation for the first request, then the second request detects that a duplicate operation is being performed and throws an error message. The users think their operation failed, but it actually succeeded. The error description of sc-win32-status 64 is: "The specified network name is no longer available." This leads me to believe, given that both POST requests show an HTTP status of 200, that the server is successful in serving the request, but the client is never notified and resubmits the request. How can I troubleshoot this? Any ideas what could be causing this behavior on their internal network only? I should mention, this is happening at two separate client sites, but does not happen at six of our other client sites, or in our office, or connecting to any of our eight clients over the web. What could be making this reproducible 100% of the time on their local network but 0% of the time anywhere else? Update: I found a very small number of the duplicated POST requests had sc-win32-status of 995 instead of 64 as originally reported. The error description of sc-win32-status=995 is: "The I/O operation has been aborted because of either a thread exit or an application request." This doesn't make any sense (considering I have full access to the code). I still don't understand how or why this issue is occurring, but the new error code leads me to believe it may not be a network issue after all and I am now investigating the possibility of a random code bug.
