  • How to Return A File and a strongly Typed data at the same time?

    - by chobo2
    Hi I am using asp.net mvc 1.0 and I want to return a XML file but I also want to return a strongly typed data back so I can update some fields. Like the XML file will contain users who failed to be inserted into the database. So I want that to appear as a dialog save box what asp.net mvc return file() would do. However I also want to return on the page like values like how many users failed to be added, how many users where added, etc. So I want to use scafolding with the class file I want to pass it along. If this was a view I could pass it along as an object model but I don't see a parameter for that in File(). I also don't want to save the xml file onto the harddrive I want to do it through memory. So have a link that would display on the page to download the file and show the the data I want would not be desired.

  • How do i force a file to be deleted? Windows server 2008

    - by acidzombie24
    On my site a user may upload a file (pic, zip, audio, video, whatever). He then may decide to replace it with a newer revision. This user may upload a file, make a post then decide to put up a new revision replacing the old (lets say its a large zip or tar.gz file). Theres a good chance people may be downloading it if he sent out an email or even im for the home user. Problem. I need to replace the file and people may be downloading and it may be some minutes before it is deleted. I dont want my code to stall until i cant delete or check every second to see if its unused (especially bad if another user can start and he takes long creating a cycle). How do i delete the file while users are downloading the file? i dont care if they stop i just care that the file can be replaced and new downloads are the new revision.

  • Change a File Type’s Icon in Windows 7

    - by Trevor Bekolay
    In Windows XP, you could change the icon associated with a file type in Windows Explorer. In Windows 7, you have to do some registry hacking to change a file type’s icon. We’ll show you a much easier and faster method for Windows 7. File Types Manager File Types Manager is a great little utility from NirSoft that includes the functionality of Windows XP’s folder options and adds a whole lot more. It works great in Windows 7, and its interface makes it easy to change a bunch of related file types at once. A common problem we run into are icons that look too similar. You have to look for a few seconds to see the difference between the movies and the text files. Let’s change the icon for the movie files to make visually scanning through directories much easier. Open up File Types Manager. Find the “Default Icon” column and click on it to sort the list by the Default Icon. (We’ve hidden a bunch of columns we don’t need, so you may find it to be farther to the right.) This groups together all file extensions that already have the same icon. This is convenient because we want to change the icon of all video files, which at the moment all have the same default icon. Click the “Find” button on the toolbar, of press Ctrl+F. Type in a file type that you want to change. Note that all of the extensions with the same default icon are grouped together. Right click on the first extension whose icon you want to change and click on Edit Selected File Type, or select the first extension and press F2. Click the “…” button next to the Default Icon text field. Click on the Browse… button. File Types Manager allows you to select .exe, .dll, or .ico files. In our case, we have a .ico file that we took from the wonderful public domain Tango icon library. Select the appropriate icon (if you’re using a .exe or .dll there could be many possible icons) then click OK. Repeat this process for each extension whose icon you would like to change. Now it’s much easier to see at a glance which files are movies and which are text files! Of course, this process will work for any file type, so customize your files’ icons as you see fit.

  • Hex Dump using LINQ (in 7 lines of code)

    - by Fabrice Marguerie
    Eric White has posted an interesting LINQ query on his blog that shows how to create a Hex Dump in something like 7 lines of code.Of course, this is not production grade code, but it's another good example that demonstrates the expressiveness of LINQ.Here is the code:byte[] ba = File.ReadAllBytes("test.xml");int bytesPerLine = 16;string hexDump = ba.Select((c, i) => new { Char = c, Chunk = i / bytesPerLine })    .GroupBy(c => c.Chunk)    .Select(g => g.Select(c => String.Format("{0:X2} ", c.Char))        .Aggregate((s, i) => s + i))    .Select((s, i) => String.Format("{0:d6}: {1}", i * bytesPerLine, s))    .Aggregate("", (s, i) => s + i + Environment.NewLine);Console.WriteLine(hexDump); Here is a sample output:000000: FF FE 3C 00 3F 00 78 00 6D 00 6C 00 20 00 76 00000016: 65 00 72 00 73 00 69 00 6F 00 6E 00 3D 00 22 00000032: 31 00 2E 00 30 00 22 00 20 00 65 00 6E 00 63 00000048: 6F 00 64 00 69 00 6E 00 67 00 3D 00 22 00 75 00000064: 3E 00Eric White reports that he typically notices that declarative code is only 20% as long as imperative code.

  • Can I remove all-caps and shorten the disclaimer on my License?

    - by stefano palazzo
    I am using the MIT License for a particular piece of code. Now, this license has a big disclaimer in all-caps: THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF... ... I've seen a normally capitalised disclaimer on the zlib license (notice that it is above the license text), and even software with no disclaimer at all (which implies, i take it, that there is indeed a guarantee?), but i'd like some sourced advice by a trusted party. I just haven't found any. GNU's License notice for other files comes with this disclaimer: This file is offered as-is, without any warranty. Short and simple. My question therefore: Are there any trusted sources indicating that a short rather than long, and a normally spelled rather than capitalised disclaimer (or even one or the other) are safely usable in all of the jurisdictions I should be concerned with? If the answer turns out to be yes: Why not simply use the short license notice that the fsf proposes for readme-files and short help documents instead of the MIT License? Is there any evidence suggesting this short 'license' will not hold up? For the purposes of this question, the software is released in the European Union, should it make any difference.

  • OSB and Ubuntu 10.04 - Too Many Open Files

    - by jeff.x.davies
    When installing the latest Oracle Service Bus (11gR1PS3) onto my Ubuntu 10.04 system, the Eclipse IDE was complaining about there being too many open files. The Oracle Service Bus and the Oracle Enterprise Pack for Eclipse (aka OEPE) do make use of ALOT of files. By default, Ubuntu will restrict each user to 1024 open files. A much more realistic number for OSB development is 4096. Changing the file limit in Ubuntu is fairly simple (if arcane). You will need to modify two different files and then restart your server. First, you need to modify the limits.conf file as the root user. Open a terminal window and enter the following command: sudo gedit /etc/security/limits.conf Add the following 2 lines to the file. The asterisk simply means that the rule will apply to all users. * soft nofile 4096 * hard nofile 4096 Save your changes and close gedit. The second file to change is the common-session file. Use the following command: sudo gedit /etc/pam.d/common-session Add the following line: session required pam_limits.so Save the file and exit gedit. Restart your machine. You shouldn't have any more problems with too many open files anymore.

  • DropSpace Syncs Android Files to Dropbox

    - by ETC
    DropSpace is a free Android application that fixes the primary issue that plagues the official Dropbox app for Android–the lack of true file synchronization. Grab a copy of DropSpace and start enjoying true file syncing on the go. The official Dropbox app is limited to grabbing files from your Dropbox account or pushing files from your phone to your Dropbox account. Actual file synchronization, this manual push/pull model aside, is nowhere to be found. DropSpace fills that gap by enabling file synchronization between your SD card directories and your Dropbox directories. It’s packed with handy features including restricting file syncing to Wi-Fi connection only (great if you don’t want to chew up your very limited data plan) as well as numerous toggles for various settings like whether it should delete remote files if the local file is deleted, how often it should run the sync service, and more. Hit up the link below to grab a copy and take it for a test drive. DropSpace is free and works wherever Android does; Dropbox account required.

  • How to make new file permission inherit from the parent directory?

    - by Wai Yip Tung
    I have a directory called data. Then I am running a script under the user id 'robot'. robot writes to the data directory and update files inside. The idea is data is open for both me and robot to update. So I setup the permission and owner group like this drwxrwxr-x 2 me robot-grp 4096 Jun 11 20:50 data where both me and robot belongs to the 'robot-grp'. I change the permission and the owner group recursively like the parent directory. I regularly upload new files into the data directory using rsync. Unfortunately, new files uploaded does not inherit the parent directory's permission as I hope. Instead it looks like this -rw-r--r-- 1 me users 6 Jun 11 20:50 new-file.txt When robot tries to update new-file.txt, it fails due to lack of file permission. I'm not sure if setting umask helps. In anycase the new files does not really follow it. $ umask -S u=rwx,g=rx,o=rx I'm often confounded by Unix file permission. Do I even have a right plan? I'm using Debian lenny.

  • How can I do a large file upload using Sinatra, haml, nginx, and passenger?

    - by mmr
    Hi all, I need to be able to allow a user to upload 30-60 mb files at a time. Right now, I'm solving the problem with a simple form post: %form{:action=>"/Upload",:method=>"post",:enctype=>"multipart/form-data"} - @theModelHash.each do |key,value| %br %input{:type=>"checkbox", :name=>"#{key}", :value=>1, :checked=>value} =key %br %input{:type=>"file",:name=>"file"} %input{:type=>"submit",:value=>"Upload"} This form allows the user to select processing options contained in theModelHash and upload a file for processing. Problem is, this method both freezes the user's UI and also requires that the entire form be reposted when the user presses the 'back' button. I've looked at SWFUpload, but have no idea how to integrate that into my relatively simple app. There's a page here about integrating it with Rails, but I'm using Sinatra, and am new enough to this whole web programming thing that I don't know how to modify those files to work with what I need to do. Is there a how-to to add large file uploads to my form there? Something relatively simple that just adds in a progress bar and doesn't repost? I feel like I'm having to triple the size of my application just to make this feature play nice, and that's bothering me a bit.

  • Modifying value of "Rating" column within Explorer for arbitrary file types.

    - by Fake Name
    Basically, I have a large body of assorted media (text, images, flash files, archives, folders, etc...) and I'm attempting to organize it. Windows Explorer has a rating column, but there seems to be no way to modify the rating of the files short of opening them in their type-specific software (e.g. Media player, or Photo viewer). However, this does not work when the file is of an unsupported type (.rar, .swf ...), or a directory. I'd be more than willing to consider a file-manager replacement (I've alreadly looked at quite a few, Directory Opus, Total Commander, etc...), or even a solution that stores the rating metadata in a hidden file in each folder, or a separate database. The one real critical requirement is the ability to sort by rating, and being filetype-agnostic. Basically, is there any way to categorize a large collection of assorted files by rating that will work with any file type, including directories? - Ideally, there would be an easy way to add arbitrary columns to windows explorer, and edit them directly. However, there seems to be no way to do this. The rating column is the next best thing.

  • Pivot Table Does Not Refresh Source

    - by AME
    Typically, when selecting a data source for a pivot table in Excel 2013, it is possible to refresh the table by selecting "refresh table" or "refresh all". This triggers an update in the Pivot Table based on changes in the underlying data source. However, I am running into a case where this functionality does not prompt a refresh of the pivot table. What might be causing the pivot table in Excel 2013 to remain static when selecting "refresh data"?

  • Rsync: remote source and destination

    - by goncalopp
    If both source and destination are remote, rsync complains: The source and destination cannot both be remote. rsync error: syntax or usage error (code 1) at main.c(1156) [Receiver=3.0.7] Is there a insurmountable technical obstacle to making rsync do this? Or it's simply a case of it's-not-yet-implemented? It seems relatively easy to create a local buffer in memory that mediates the transfer between two remotes, holding both hashes and data. Conversely, is there other (unix) software that implements this functionality?

  • Looking for good Open Source email server

    - by rockinthesixstring
    I'm currently running MailEnable as my email server, it's ok but lacking. I'm looking for a better alternative and am wondering about Open Source. I'm a huge fan of the Smarter Mail, and will pay if it's the best I can get... But I have been learning that there is some good stuff out there in the Open Source community (IE: I've started using PFSense and I love it). Does anyone have any suggestions?

  • What is a good open source software to manage my Tripp-lite UPS (Uninterruptible power supply)

    - by Beatle
    I have a Tripp-Lite Smart150rmxl2ua UPS. The software from their website doesn't seem to work properly. I also tried "apcupsd" which is an open source software which i am supposed to be able to use to manage my UPS and I had no luck with that either since Windows 7 did not want to install and use the drivers since they are "incompatible". Is there another good working open source software out there? It sucks that Tripp-Lite doesn't supply its customers with working software.

  • How to create a .MAP file from a .PDB file

Anyone know a good tool for this? Thanks.

  • Float PPM image file format?

    I've found a PPM image with the header starting with PF. The resolution number is stored in floating point (-1.000). No comments are inserted to get how it was produced. From the resolution, each pixel is composed by 12 bytes (4 bytes per component)... I suppose they are float or integer numbers. The problem is that I cannot get a clear image. Someone has already found this kind of images?
