  • ASP.net MVC 2.0 using the same form for adding and editing.

    - by Chevex
    I would like to use the same view for editing a blog post and adding a blog post. However, I'm having an issue with the ID. When adding a blog post, I have no need for an ID value to be posted. When model binding binds the form values to the BlogPost object in the controller, it will auto-generate the ID in entity framework entity. When I am editing a blog post I DO need a hidden form field to store the ID in so that it accompanies the next form post. Here is the view I have right now. <% using (Html.BeginForm("CommitEditBlogPost", "Admin")) { %> <% if (Model != null) { %> <%: Html.HiddenFor(x => x.Id)%> <% } %> Title:<br /> <%: Html.TextBoxFor(x => x.Title, new { Style = "Width: 90%;" })%> <br /> <br /> Summary:<br /> <%: Html.TextAreaFor(x => x.Summary, new { Style = "Width: 90%; Height: 50px;" }) %> <br /> <br /> Body:<br /> <%: Html.TextAreaFor(x => x.Body, new { Style = "Height: 250px; Width: 90%;" })%> <br /> <br /> <input type="submit" value="Submit" /> <% } %> Right now checking if the model is coming in NULL is a great way to know if I'm editing a blog post or adding one, because when I'm adding one it will be null as it hasn't been created yet. The problem comes in when there is an error and the entity is invalid. When the controller renders the form after an invalid model the Model != null evaluates to false, even though we are editing a post and there is clearly a model. If I render the hidden input field for ID when adding a post, I get an error stating that the ID can't be null. Any help is appreciated. EDIT: I went with OJ's answer for this question, however I discovered something that made me feel silly and I wanted to share it just in case anyone was having a similar issue. The page the adds/edits blogs does not even need a hidden field for id, ever. The reason is because when I go to add a blog I do a GET to this relative URL BlogProject/Admin/AddBlogPost This URL does not contain an ID and the action method just renders the page. The page does a POST to the same URL when adding the blog post. The incoming BlogPost entity has a null Id and is generated by EF during save changes. The same thing happens when I edit blog posts. The URL is BlogProject/Admin/EditBlogPost/{Id} This URL contains the id of the blog post and since the page is posting back to the exact same URL the id goes with the POST to the action method that executes the edit. The only problem I encountered with this is that the action methods cannot have identical signatures. [HttpGet] public ViewResult EditBlogPost(int Id) { } [HttpPost] public ViewResult EditBlogPost(int Id) { } The compiler will yell at you if you try to use these two methods above. It is far too convenient that the Id will be posted back when doing a Html.BeginForm() with no arguments for action or controller. So rather than change the name of the POST method I just modified the arguments to include a FormCollection. Like this: [HttpPost] public ViewResult EditBlogPost(int Id, FormCollection formCollection) { // You can then use formCollection as the IValueProvider for UpdateModel() // and TryUpdateModel() if you wish. I mean, you might as well use the // argument since you're taking it. } The formCollection variable is filled via model binding with the same content that Request.Form would be by default. You don't have to use this collection for UpdateModel() or TryUpdateModel() but I did just so I didn't feel like that collection was pointless since it really was just to make the method signature different from its GET counterpart. Thanks for the help guys!

  • How to generate a VBR video from stream of YUV images?

    - by zitronic
    My hardware (video capture card) gives me the images in YV12 (YUV 420) format and I am trying to generate a video from it. I am using C++ under windows and I would like to generate a mpeg-4 VBR video from that stream but I dont know where I should start... (I need it to be VBR because it is a security camera and there will be a lot of repeated frames) Is there any library that does something like this?

  • allow editing of config files by WIndows Server 2008 admins running non-elevated?

    - by Justin Grant
    My company produces a cross-platform server application which loads its configuration from user-editable configuration files. On Windows, config files are locked down at Setup time to allow reading by all users but restrict editing to Administrators only. Unfortunately, on Windows Server 2008, even local administrators no longer have admin privileges (because of UAC) unless they're running an elevated app. My question is: if a Windows Server 2008 admin wants to edit an admins-only config file, how does he normally do it? Is he forced to use a text editor which is smart enough to auto-elevate when elevation is needed, like Windows Explorer does in response to access denied errors? Or is there something that we can do in our app (e.g. in ACLs we lay down at setup time) which signal apps (or explorer) that elevation is needed before editing the file or which otherwise make our app friendlier to admins running on modern Windows OS's?

  • Drupal: what's the easiest way to let my customer to upload video thumbnails and associate them to v

    - by Patrick
    hi, my customer wants a gallery of videos and images (small thumbnails) and if you click on one of them you can see the picture / video in the overlaying lightbox). Now, I cannot install auto-generating video thumbnails because I don't have access to ffmpeg module on the server. I can only allow my customer to upload these thumbnails by himself. I'm using image and video CCK fields for each node to allow my customer images and videos. However I dunno how should I let him upload thumbnails for his videos. Should I create an additional Image CCK field for this ? Consequently, I should somehow associate the videos with the images in the design and my customer should pay attention to place them in the same order.. this is not very nice solution, but it is the only one that came to my mind so far. Furthermore, I'm using the lightbox I should somehow ignore the video thumbnails and display the videos instead... some tips ? Thanks

  • Locking a detail view if a user is editing the item...

    - by BenTheDesigner
    Hi All I am developing a user manager which must control access to the detail view of editable items. At present, when a user clicks 'edit', the application queries the link table to check if a user is currently editing that page, if not, it allows access to the page and then inserts a record into the link table preventing another user from editing the same page at the same time. My question is what would the best way to handle the removal of records if say a user exists the browser without saving etc, therefore no action to remove the record. I have a couple of ideas but would like other input before I decide. BenTheDesigner

  • What do the numbers 240 and 360 mean when downloading video? How can I tell which video is more compressed?

    - by DaMing
    I have downloaded some computer science lectures from YouTube recently. There is usually more than one choice of file size and file format to download. I noticed that for the same video, the downloadable one with FLV 240 extension is larger than another one with MPEG4 360 extension. What does the number (240 and 360) mean? And which file's compression rate is bigger? That is to say, which one removed much more file elements than the other from the orignal file?

    - by laggingreflex
    I want to customize the color scheme of the comments in my code, by editing the .tmTheme How to know which of the <dict> <key> corresponds to which element of the code? Like, I can guess some of them but not every one of them is that obvious..

  • how to protect from editing or converting to text a pdf file?

    - by Layla
    I am using a version of Ms Office of 2010, it was a beta version of public domain (I dont recall the name, but I believe it was called Blue version or something like that). I usually make my documents using the MS Word and then saving it like a pdf file using the function to publish as a pdf file within Word. The problem that I have is that some people are converting my documents into text, putting their name on it, and credited my work to them; so I would like to know if there is a way to: protect with a password the editing of my document protect it from converting into txt, with a password if its possible maybe but a digital signature in which it says my name as an author I want that the people who access it can only read it, and nothing more. I am using MS Word 2010 and Foxit Pdf (an old version), I usually do not use Adobe Acrobat. Thanks

  • MKV video suddenly stops playing after random time - what could this be?

    - by MEM
    I have this HP USB drive (16GB, NTFS formatted) that has, a MKV video. The USB is always detectable, so is the MKV, but when I connect that USB drive with that MKV video on my HT-C5530 home cinema USB port, the playback just suddenly stops after random time, and it returns to the main menu when I can see the pen and it's contents. I really have no clue about what could be the issue here, has someone else experience something similar? That may help me out on this.

  • Flash in browsers does not play sound accurately using Pulse network audio

    - by Dave M G
    I use PulseAudio to send sound over the LAN to an audio server. When playing any Flash media in Firefox or Chrome, the sound flutters, as if the volume were going up and down every second. The problem does not exhibit with any other software, and I think it's specific to how Flash interacts with my sound set up. How do I get Flash to play nice with the PulseAudio network sound server? Update I have discovered that I can stop the sound fluttering if I follow these steps: Start a Flash video Run pulseaudio --kill on the server Wait about 7 seconds After this, the PulseAudio server automatically respawns, and the sound in the Flash video is perfect. The problem now, though, is that I have to do this every time I start a Flash video. This is obviously not desireable. So, the question is, how do I make whatever it is that makes the sound work when I go through these steps stick so that I don't have to do them? Also, I've uploaded some PulseAudio log output to Pastebin, taken while attempting to play a Flash video, if that helps. I've tried to get logging details from Flash, but despite installing and enabling Flash for debugging, it has not generated any ouput at all. Details I have uploaded an example video of the problem onto Youtube. In the video you can see the opening of a Ted Talk video, and the sound flutters as it plays. The video also stutters while playing back. Here are my sound device output settings:

  • My New BDD Style

    - by Liam McLennan
    I have made a change to my code-based BDD style. I start with a scenario such as: Pre-Editing * Given I am a book editor * And some chapters are locked and some are not * When I view the list of chapters for editing * Then I should see some chapters are editable and are not locked * And I should see some chapters are not editable and are locked and I implement it using a modified SpecUnit base class as: [Concern("Chapter Editing")] public class when_pre_editing_a_chapter : BaseSpec { private User i; // other context variables protected override void Given() { i_am_a_book_editor(); some_chapters_are_locked_and_some_are_not(); } protected override void Do() { i_view_the_list_of_chapters_for_editing(); } private void i_am_a_book_editor() { i = new UserBuilder().WithUsername("me").WithRole(UserRole.BookEditor).Build(); } private void some_chapters_are_locked_and_some_are_not() { } private void i_view_the_list_of_chapters_for_editing() { } [Observation] public void should_see_some_chapters_are_editable_and_are_not_locked() { } [Observation] public void should_see_some_chapters_are_not_editable_and_are_locked() { } } and the output from the specunit report tool is: Chapter Editing specifications    1 context, 2 specifications Chapter Editing, when pre editing a chapter    2 specifications should see some chapters are editable and are not locked should see some chapters are not editable and are locked The intent is to provide a clear mapping from story –> scenarios –> bdd tests.

  • Commands don't have permission when using absolute path

    - by Markos
    I have folders set up this way: /srv/samba/video getfacl /srv/samba/video # file: srv/samba/video # owner: root # group: nogroup user::rwx group::--- group:sambaclients:rwx group:deluge:rwx mask::rwx other::--- default:user::rwx default:group::--- default:group:sambaclients:rwx default:group:deluge:rwx default:mask::rwx default:other::--- That means, user deluge has rwx to folder /srv/samba/video. However, when running command as user deluge, I am getting weird permission errors. When in folder /srv/samba/video: sudo -u deluge mkdir foo works flawlessly. But when using absolute path: sudo -u deluge mkdir /srv/samba/video/foo I am getting permission denied. When running sudo -u deluge id, I get output uid=113(deluge) gid=124(deluge) skupiny=124(deluge) which shows that user deluge is indeed in group deluge. Also, the behavior was the same when I gave the permissions also to user deluge not just group deluge. When executing as non-system user, it does work. The reason that I want to use absolute paths is that I am using automatically triggered post-download script which extracts some files into the folder. I have spent way too many hours to solve this problem myself. mkdir isn't the only command that fails, touch is doing the same thing, so I suspect that it's not mkdir's fault. If you need more info, I will try to put it in here, just ask. Thanx in advance. Edit: It seems that the root of the problem is acl set on perent folder /srv/samba, which indeed does not grant permissions to deluge (but neither denies it). getfacl /srv/samba # file: srv/samba # owner: root # group: nogroup user::rwx group::--- group:sambaclients:rwx mask::rwx other::--- default:user::rwx default:group::--- default:group:sambaclients:rwx default:mask::rwx default:other::--- If I grant the permission also to this folder, it suddenly starts to work so I believe that the acl on /srv/samba is somehow denying the permissions to deluge. So the question is: how do I set acl to both /srv/samba and /srv/samba/video so that sambaclients have access to whole /srv/samba and subdirectories and deluge has access only to /srv/samba/video and subdirectories?

  • Skin Object Tokens for DotNetNuke 5 - 8 Videos

    In this tutorial we demonstrate how to use Skin Object Tokens in DotNetNuke v5 and above. Skin Object tokens are a new skinning method introduced in DotNetNuke 5 for adding tokens into a DotNetNuke skin. A Skin Object Token is a web user control, it covers skin elements such as the logo, menu, search, login links, date, copyright, languages, links, banners, privacy, terms of use etc. This new Object token method has been introduced into DotNetNuke with the idea of making it simpler to add a skin object into a DotNetNuke skin. The videos contain: Video 1 - Introduction to HTML Object Token Skinning Video 2 - Basic Styling of a Skin and Creating Multiple Content Panes Video 3 - Styling, Control Panel, Login and Register Skin Object Tokens Video 4 - Packaging, Installing, Testing and Viewing the ASCX Version of the Skin Video 5 - Viewing the Attributes for Skin Object Tokens, Logo Token, Search Token Video 6 - Breadcrumb Token, Text Token and Localization, Links Token Video 7 - More Skin Tokens and Token Replacement Video 8 - Demonstration of the Object Tokens and Bug Fixing Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • What is the correct way to install ATI Catalyst Video Drivers?

    - by Stephen Myall
    I am planning on doing a fresh install of 12.04 LTS and want to know what is the correct way to install ATI Catalyst Video Drivers in 12.04 LTS? In a previous AU question relating to 11.10 (here) NOT 12.04 the accepted response stated that ia32-libs was a dependency (even for 64bit machines). I studied other Q&A on AU and the reason for asking this specific question is that I wasn't sure about some of the dependencies needed. I was also receiving conflicting advice on other reputable websites which put doubts in my mind on what the correct approach was.
