  • [LINQ] Nested query problem

    - by code-zoop
    I have 3 classes in C#: classclass Folder { int Id { get; set; } List<File> files { get; set;} } class File { int Id { get; set; } Author author { get; set; } } class Author { int Id { get; set; } string Name { get; set; } } I have a list of Folder items (List): var folders = getAllFolders(); How can I use Linq to return a list of Folders from the list when i only know the Author id of the files? I need the list to contain all folders where a given Author has created a file! Thanks

  • transferring subversion changes between linux and windows

    - by andreas buykx
    Hi all, What is the best way to transfer changes that include new and deleted directories and/or new and deleted (actually moved) files in those directories from a subversion repository on linux to windows? I do my developments on linux using a subversion repository, but I have to test my changes on windows as well. My windows machine has a tortoisesvn repository which I tried to patch with a svn diff output. This failed miserably since my patch contains a renamed (i.e. deleted and added under a different name) directory, a new directory and the files in there. Do I do things wrong by just applying the svn diff output as a patch in tortoisesvn? For now I think that my best option is to have the windows tree on the same svn version as the linux tree and just copy the entire changed directory over the existing directory. Would that work?

  • s3cmd setacl to grant 'Authenticated Users'

    - by rynop
    I'm using jgit to create a remote in s3. Problem I'm having is when I do a jgit push s3 master it creates the files in s3 as owned by me. I want to keep the files private, and be read/write by 'Authenticated users'. I'd like to be able to either set acl: authenticated-read in the ~/.jgit file OR be able to modify the acl after the push: s3cmd --add-header=x-amz-acl:authenticated-read setacl --acl-private s3://my.bucket/repo/* Neither of these work. How do i use jgit and push to s3 and keep it private, and let anyone with auth read/write?

  • Is it possible to capture a "file not found" from another process and then return a file to that pro

    - by Neil N
    I have a legacy application that looks for files in a directory. It does not handle missing files very well. What I want to do is "capture" the file not found errors, and send another file back to the calling app instead. Similar to how you could handle a 404 error on a webserver and return something based on what the requested URL was, except on the local file system. Is this possible? And more preferably, is it possible in .Net?

  • Making Wix uninstall an old plug-in when performing an upgrade

    - by IanM
    I have a main product which is installed using Wix and has its own UpgradeCode In between releases of the main product we sometimes release plug-ins which add or patch some functionality. The plug-ins are packaged in their own Wix generated .msi files with their own UpgradeCodes and generally install addition files is a separate folder from the main product. I want to create a new version of the main product which includes the functionality which was previously available in a plug-in. A user upgrading to the new version will no longer need the plug-in so it would be nice to uninstall it as part of the upgrade. Is there a way of making Wix uninstall a product with UpgradeCode2 when it is upgrading product with UpgradeCode1?

  • GVim highlighting with matchadd eventually slows down?

    - by Kyle MacFarlane
    I have the following in ~/.vim/ftplugin/python.vim to highlight long lines, accidental tabs and extra whitespace in Python files: hi CustomPythonErrors ctermbg=red ctermfg=white guibg=#592929 au BufWinEnter *.py call matchadd('CustomPythonErrors', '\%>80v.\+', -1) au BufWinEnter *.py call matchadd('CustomPythonErrors', '/^\t\+/', -1) au BufWinEnter *.py call matchadd('CustomPythonErrors', '\s\+$', -1) au BufWinLeave *.py call clearmatches() The BufWinLeave is so that the matches are cleared when I switch to another file in case that file isn't a .py file. It's an essential feature for me when working with something like Django. It all works fine for random amounts of time; from ten minutes to hours (my guess is it depends on how many files I open/close). But eventually when any line over 80 characters is displayed GVim slows to a halt and requires a restart. Does anyone have any ideas why this would eventually slow down?

  • Does a .NET Framework installation interfere with existing VB6 runtime or COM installations?

    - by faredoon
    Consider this situation: There's a critical VB6 desktop application running on a production box. There is a possibility of installing a .NET application that queries the same DB that the VB6 application queries, which is an SQL Server 2000 DB. The VB6 application also depends on third-party ActiveX controls (registered .ocx files). The concern is - will the .NET Framework installation replace any files or break the VB6 runtime in any way. In other words, can we safely assume that an installation of the .NET Framework is completely independent of any previous VB6 installations and will not interfere with the running application?

  • Max number of web methods?

    - by Rippo
    Guys I have a web service in asp.net 2.0 that has 234 methods. It seems that when I add another method the site does not compile in VS2005 until I remove one first. I get a message saying that the new method I just added does not exist in a file that belongs in the Microsoft.Net/.../Temporary Files directory. I have restarted IIS, closed down VS2005, removed all files from this temp directory but to no avail. The only way to get the code to compile is to remove another one so as to keep 234 methods.... I can consistency replicate this behaviour so it cannot be my code. Now I know this seems strange but it is true! One other strange thing is that exactly 100 of the method names begin with the word GetXXXyyyZZZ Has anyone else experienced problems with the maximum number of methods that are allowed in a web service? Many Thanks

  • Generate Windows .lnk file with PHP

    - by Andrei
    Hello, I'm working on a project which involves an FTP server running ProFTPd and a PHP/MySQL backend that creates accounts for users. Upon the creation of accounts, users are sent e-mails with their account details and instructions for downloading FileZilla or CyberDuck, depending on their OS, detected via user-agent string. To make things easier for novices, I thought of having .lnk files generated for FileZilla with the account logins details as parameters, so they would just have to click on the .lnk files to open up the server. This is not crucial feature but more of a technical challenge. My questions are : is this even feasible ? are there any alternatives (eg. generating a .bat with a script pointing to the Filezilla executable ?) are there any issues, perhaps with relative / absolute paths pointing to the executable ? to go even further, what would be the simplest way of providing users with software with FTP access on a single account / single server (web interface is not an option).

  • Create a new output file in ant replace task

    - by Sathish
    Ant replace task does a in-place replacement without creating a new file. The below snippet replaces tokens in any of the *.xml files with the corresponding values from my.properties file. <replace dir="${projects.prj.dir}/config" replacefilterfile="${projects.prj.dir}/my.properties" includes="*.xml" summary="true"/'> I want those *.xml files that had their tokens replaced be created as *.xml.filtered (for e.g.) and still have the original *.xml. Is this possible in Ant with some smart combination of tasks and concepts ?

  • Base64 Encoded Data - DB or Filesystem

    - by Marty
    I have a new program that will be generating a lot of Base64 encoded audio and image data. This data will be served via HTTP in the form of XML and the Base64 data will be inline. These files will most likely break 20MB and higher. Would it be more efficient to serve these files directly from the filesystem or would it be feasible to store the data in a MySQL database? Caching will be set up but overall unnecessary because it is likely that this data will be purged shortly after it is created and served. i know that storing binary data in the DB is frowned upon in most circumstances but since this will all be character data I want to see what the consensus is. As of now, I am leaning toward storing them in the filesystem for efficiency reasons but if it is feasible to store them in a database it would be much easier to manage the data.

  • How to force HttpWebRequest to use cache in ASP.NET environment?

    - by piotrsz
    In my ASP.NET app I use HttpWebRequest for fetching external resources which I'd like to be cached. Consider the following code: var req = WebRequest.Create("http://google.com/"); req.CachePolicy = new HttpRequestCachePolicy(HttpRequestCacheLevel.CacheIfAvailable); var resp = req.GetResponse(); Console.WriteLine(resp.IsFromCache); var answ = (new StreamReader(resp.GetResponseStream())).ReadToEnd(); Console.WriteLine(answ.Length); HttpWebRequest uses IE cache, so when I run it as normal user, data is cached to %userprofile%\Local Settings\Temporary Internet Files and next responses are read from cache. I thought that when such code is run inside ASP.NET app, data will be cached to ...\ASPNET\Local Settings\Temporary Internet Files but it is not and cache is never used. What I am doing wrong? How to force HttpWebRequest to use cache in ASP.NET environment?

  • Leverage cloud and programming to share GB's of photos

    - by jcmoney
    My friends and I went on a trip and we have over 8 GB of photos we want to share. We live in different geographic locations and all of us (14 people) have a part of the 8 GB. I was wondering if there's a way to leverage my php skills to share all these photos. My current plan is to make a simple site that you can upload a bunch of files and also list those files for people to download (probably a compressed folder of a bunch of selected ones) but was wondering if there's a better way or if I'm grossly underestimating scalability issues. All of us have high speed internet (essentially T1) and I was planning on using Amazon EC2 since this is a heavy task but for a short time period. That's also the reason I can't use dropbox or similar services since they have a 2GB cap (and I don't want to have everyone sign up and install something). I also don't want to set up anything too tricky since not all of them are tech savvy.

  • PHP getting blank pages after submit a form + signal Segmentation fault (11)

    - by Ole Media
    I few days ago I update my macbook pro to snow leopard, and since then some php files are not showing. This is what happens: I created a php form, when going to 'http://localhost/webform.php' I can see the form just fine. Then, once I submit the form, I just get a blank page. I enable error and warnings reporting under php.ini to make sure I'm not missing something, but still I'm not getting anything, just the blank page. Then I checked under apache log files, and what I notice is that every time I submit the form I see the following line coming up under the apache logs: [Wed Apr 07 21:40:28 2010] [notice] child pid 70223 exit signal Segmentation fault (11) I'm clueless on this one. Any ideas on how to fix it?

  • Python preprocessing imports

    - by FiloSottile
    I am managing a quite large python code base (2000 lines) that I want anyway to be available as a single runnable python script. So I am searching for a method or a tool to merge a development folder, made of different python files into a single running script. The thing/method I am searching for should take code split into different files, maybe with a starting __init___.py file that contains the imports and merge it into a single, big script. Much like a preprocessor. Best if a near-native way, better if I can anyway run from the dev folder. I have already checked out pypp and pypreprocessor but they don't seem to take the point. Something like a strange use of __import__() or maybe a bunch of from foo import * replaced by the preprocessor with the code? Obviously I only want to merge my directory and not common libraries.

  • How do I use dependencies in a makefile without calling a target?

    - by rassie
    I'm using makefiles to convert an internal file format to an XML file which is sent to other colleagues. They would make changes to the XML file and send it back to us (Don't ask, this needs to be this way ;)). I'd like to use my makefile to update the internal files when this XML changes. So I have these rules: %.internal: $(DATAFILES) # Read changes from XML if any # Create internal representation here %.xml: %.internal # Convert to XML here Now the XML could change because of the workflow described above. But since no data files have changed, make would tell me that file.internal is up-to-date. I would like to avoid making %.internal target phony and a circular dependency on %.xml obviously doesn't work. Any other way I could force make to check for changes in the XML file and re-build %.internal?

  • Passing HttpFileCollectionBase to the Business Layer - Bad?

    - by Terry_Brown
    hopefully there's an easy solution to this one. I have my MVC2 project which allows uploads of files on certain forms. I'm trying to keep my controllers lean, and handle the processing within the business layer of this sort of thing. That said, HttpFileCollectionBase is obviously in the System.Web assembly. Ideally I want to call to something like: UserService.SaveEvidenceFiles(MyUser user, HttpFileCollectionBase files); or something similar and have my business layer handle the logic of how and where these things are saved. But, it feels a little icky to have my models layer with a reference to System.Web in terms of separation of concerns etc. So, we have (that I'm aware of) a few options: the web project handling this, and my controllers getting fatter mapping the HttpFileCollectionBase to something my business layer likes passing the collection through, and accepting that I reference System.Web from my business project Would love some feedback here on best practice approaches to this sort of thing - even if not specifically within the context of the above.

  • Determine branch of origin from bzr blame

    - by Dave Aaron Smith
    I had a complicated change that affected a bunch of files. I don't remember what bazaar branch I wrote that change in. We have a somewhat complicated merge setup, so the branch I'm in now lumps that change in with a lot of other changes. I'd like to do some very similar work so it would be nice to pull the original diff. I feel like I should be able to use bzr blame. I run this command on one of the files bzr blame --long path/to/file and I find one of the pertinent lines and get something like 1107.6.213 dsmith@satie 20091202 | tinyMCE.init({ Can I use that to figure out what branch and revision the original change came from? What do the 6 and 213 stand for?

  • is it possible if callback in array_filter receive parameter ?

    - by justjoe
    i got this multiple array name $files[], who consist keys and values as below : [0] = Array ( [name] = index1.php [path] = http://localhost/php/gettingstarted/ [number] = 1 ) [1] = Array ( [name] = index10.php [path] = http://localhost/php/gettingstarted/ [number] = 2 ) [2] = Array ( [name] = index11.php [path] = http://localhost/php/gettingstarted/ [number] = 3 ) and i use this code to create new array consist of 'name' keys only. but it failed array_filter($files, "is_inarr_key('name')"); function is_inarr_key($array, $key) { //TODO : remove every array except those who got the same $key } and i got this error array_filter() [function.array-filter]: The second argument, 'is_inarr_key('name')', should be a valid callback in C:\xampp\htdocs\php\gettingstarted\index.php on line 15 so the queastion : 1. is it possible to make call-back function on array_filter has ability to receive parameter ? What is general rule of thumb on how to use callback in anyPHP built-in function ?

  • Multithreaded FTP upload. Is it possible?

    - by Arty
    I need to upload multiple files from directory to the server via FTP and SFTP. I've solved this task for SFTP with python, paramiko and threading. But I have problem with doing it for FTP. I tried to use ftplib for python, but it seems that it doesn't support threading and I upload all files one by one, which is very slow. I'm wondering is it even possible to do multithreading uploads with FTP protocol without creating separate connections/authorizations (it takes too long)? Solution can be on Python or PHP. Maybe CURL? Would be grateful for any ideas.

  • File modified date/time changes when uploaded via FTP

    - by Nate Shoffner
    Hey /g/, FTP/PHP question here. On one of my pages I load .txt files from a directory. Pretty simple. I also display the modified date of the text file using this: date('m/d/Y', filemtime($file)); This works fine on my WAMP server but when I upload the files via FTP, the modified date is changed to when they were uploaded. I'm currently hosting on a free hosting provider (freehostia to be exact). Is there any way to keep the modified date/time from changing when it's uploaded? Or is there perhaps an alternative way to go about this? Any ideas are appreciated.

  • How to generate a report of IIS settings for easy perusal?

    - by Bryan
    Hello, I'm looking for a way to (hopefully) create a text file which lists all the settings in IIS for.. Virtual Directories Web sites Which framework is used on a certain website/directory directory of hosted files etc. Basically I want to do some investigation on some of our servers to figure out where certain projects are located, without digging through right clicking and looking for the directory name manually, etc, for every domain we host. The reasoning is that I often need to find access to files/projects I haven't worked on before, but historically, we don't have a strong naming scheme, so you can't just look where something "logically" would be - so, generating a list would be very helpful. Something like this would be awesome, but I'm looking for any tips at all Domainname1.com framework: ASP.NET 1.1 directory: c:\inetpub\wwwroot\domainname1.com Applications hosted at this domain: etc, etc. Plain text, XLS, XML.. anything other than right clicking through the whole list! Thanks!
