  • How can I access form elements when using an ASP.NET MVC Ajax form?

    - by Patrick
    I've got an ajax form in an MVC 2 application. I cannot find the proper way to access the form elements within the Ajax form decleration. I can access the name of the elements with Request.Form.Keys but I can't access the actual values. I've read numerous examples of posting forms with jQuery but my form has elements created dynamically based on route values (sometimes it could be 2 text boxes sometimes 10, given unique names like so: <%= Html.TextBox("Evaluation"+Model.EvaluationId.ToString())) so I couldn't find a way to make that work with jQuery. Is there another way that I for elements can be accessed?

  • Triple (3) Monitors under Linux

    - by widgisoft
    I have a 3 monitor setup (each 1680x1050) via an Nvidia NVS440 (2 GPUs, 2 outputs per GPU totalling 4 outputs); this works fine under Windows XP,7 but caused considerable headaches under Linux (Ubuntu 9.04). I had previously used an XFX 9600GT and the onboard XFX 9300GS to produce the same result but the card was noisy and power hungry and I was hoping that there was some magical switch in the NVS4400 that got rid of this annoying problem - turns out the NVS440 is just 2 cards on one physical PCB :-p (I searched the net high and low for people using this card under Linux but found nothing, if anything the card uses less power and is fan less so I was to benefit from it either way) Anyway, using either set up there were 5 solutions available: Have 3 separate X instances, all un joined Have 3 separate X instances, adjoined by Xinerama Have 2 separate X instances - One using twin-view, both adjoined by Xinerama Have 2 separate X instances - One using twin-view but no Xinerama Have a single Twin-view setup and leave the 3rd screen unplugged :-p The 4rd option, using 2 separate X instances and twinview (but no xinerama) was the best balance in terms of performance and usability but caused 2 really annoying issues You couldn't control (without altering the shortcuts) which screen an application opened onto - and once it was opened you couldn't move it to another screen without opening up terminal and forcing it to move Nvidia's overriding or falsifying of Xinerama breaks and the 2 screens joined by Twin view behave like a single huge screen causing popups to open in the middle of both screens and maximising of windows stretches to the width of the first 2 screens Firefox can only run one instance as the same user so having multiple firefox windows requires at least 2 users The second option "feels" like the right option, but OpenGL is basically disabled and playing any sort of game or even running anything graphical causes a huge performance drop and instability - even trying to run a basic emulator for gba or gens just causes the system to fall over. It works just enough to stare at your desktop and do nothing but as soon as you start doing some work - opening windows, dragging things around - running multiple copies of firefox it just really feels slow. The last open, only going dual screen works perfectly and everything performs as required, full GPU acceleration - two logical screen spaces - perfect, just make it work across GPUs like windows! :-p Anyway, I know RandR was supposed to pick up the slack when it would introduced GPU objects of sorts to allow multiple GPUs to be stitched together to create one huge desktop at a much deeper layer than Xinerama. I was wondering if this has now been fixed (I noticed X server 1.7 is out) and whether anyone has got it running successfully? Again, my requirements are: One huge desktop to drag any window across Maximising of windows to each screen (as XP does) Running fullscreen apps on the primary screen and disabling the mouse from moving onto the others or on all 3 stretched Finally as a side note; I am aware of the Matrox triple (and dual) head splitter but even the price they go for on eBay is more than I can afford atm, my argument: I shouldn't have to buy extra hardware to get something to work on Linux when it's something that's existed in the windows world for a long time (can you tell I don't get on with X :-p); If I had the cash I'd have bought the latest version of this box already (the new version finally supports large resolutions as the displays I have 1680x1050 each).

  • Using indexes on/through a MySQL view

    - by Peeja
    We've got a MySQL table in which rows are never updated, but instead new rows are added and the old ones marked obsolete. Think Rails' acts_as_paranoid, but for every update. To make working with Rails sane, we've got a view which selects only the rows which are "current". That makes a much better "table" for our ActiveRecord model. The snag: our indexes aren't being used anymore. Queries on the view don't use the underlying tables' indexes. You can't add an index to a view. Without indexes, the app is unbearably slow. The only solution we've come up with is to build a materialized view, but that's a pain in MySQL because they're not natively supported. Is there a better way to do this?

  • How do I create multiple submit buttons for the same form in Rails?

    - by Angela
    I need to have multiple submit buttons. I have a form which creates an instance of Contact_Call. One button creates it as normal. The other button creates it but needs to have a different :attribute value from the default, and it also needs to set the attribute on a different, but related model used in the controller. How do I do that? I can't change the route, so is there a way to send a different variable that gets picked up by [:params]? And if I do then, what do I do in the controller, set up a case statement?

  • Rails: Converting from MySQL to PostGres breaks Geokit Distance Calculations???

    - by Kevin
    I recently switched my database from MySQL to PostGres. I also use GeoKit. When I started my app up with the new database already seeded, I get the following error: PGError: ERROR: function radians(character varying) does not exist LINE 1: ...COS(0.661045389762993)*COS(-2.12957994527573)*COS(RADIANS(ti... ^ HINT: No function matches the given name and argument types. You might need to add explicit type casts. Anyone know why this is breaking now? I know GeoKit still works because it's still performing the geocoding in the model per ticket when the database is seeded, it just won't do the distance calculations correctly.

  • Core Data and BOOL setup

    - by John Valen
    I am working on an app that uses Core Data as its backend for managing SQLite records. I have everything working with strings and numbers, but have just tried adding BOOL fields and can't seem to get things to work. In the .xcdatamodel, I have added a field to my object called isCurrentlyForSale which is not Optional, not Transient, and not Indexed. The attribute's type is set to Boolean with default value NO. When I created the class files from the data model, the boilerplate code added for this property in the .h header was: @property (nonatomic, retain) NSNumber * isCurrentlyForSale; along with the @dynamic isCurrentlyForSale; in the .m implementation file. I've always worked with booleans as simple BOOLs. I've read that I could use NSNumber's numberWithBool and boolValue methods, but this seems like an aweful lot of extra code for something so simple. Can the @property in the header be changed to a simple BOOL? If so is there anything to watch out for? Thanks -John

  • Second HDD not seen by Windows 7 on Dell Xps l501x

    - by George
    I have a Dell XPS Laptop (l501x). I have replaced the original Seagate 500GB hard drive with an SSD Intel 320 120GB when I first purchased it a year ago. It's been working great. The laptop is booting in about 23 seconds, so the SSD is great. I have an Acronis image created that I came back to every three months just to keep everything clean. The SSD is partitioned with one logical drive for my data. So, recently I thought since I am not using my optical drive often enough to swap it out with a HDD caddy and add my seagate 500gb hard drive. I ordered the caddy placed the HDD in it and now load Windows. It just hangs on the screen that should show the Windows logo. I have tried everything that I know and searched it online. I have uninstalled the SATA controller AHCI and let Windows install it. Still will not boot into windows. I wanted to mention that the Seagate 500GB drive was the one that came with my laptop before I switched to the Intel SSD. As you know Intel has this application called Intel Rapid Technology which loads once in a while and shows the second hard drive, but then, when I restart it hangs again and Windows will not load. As soon as I remove the HDD Caddy and restart it loads Windows fine. I also formated the Seagate 500GB HDD in NTFS and still Windows will not load. When I go into the BIOS it shows the Fixed SSD and also "Sata ODD 500GB" instead of the optical drive but it will not boot into Windows when the HDD caddy is present. There is nothing wrong with the caddy. I have another laptop (Asus) and I installed the HDD caddy and Windows 7 loads without any glitch. I don't get it. I have also flashed the BIOS because Dell had a new version (A08). I also wanted to add that I refreshed Disk Management and the Device Manager and the second drive does not display. At this point I think it's a Windows issue so before I reinstall Windows 7 Home Premium from scratch I wanted to see if there was anything I was missing. Any advice would be greatly appreciated.

  • How to use a 3rd party control inside the viewmodel?

    - by Sander
    I have a 3rd party control which among other things performs loading of some data. I want my viewmodel to keep track of this load operation and adjust its own state accordingly. If it were up to me, I'd do the data loading far away from the view, but it is not. So, I seem to be in the situation where my viewmodel depends on my view. How do I best handle this? I feel rather dirty making the view publish events to the viewmodel but I don't see any other reasonable way to get this info into the viewmodel. A similar situation might crop up with standard controls, too - imagine if your viewmodel depends on the events coming from a MediaElement - how do you properly model this? Do you put the MediaElement into the viewmodel? That doesn't sound right. If publishing the events to the viewmodel is indeed the most reasonable way, is there some common pattern used for this? How do you do it?

  • what is this 'map' mean..in django

  • Django: switch language of message sent from admin panel

    - by yoshi
    I have a model, Order, that has an action in the admin panel that lets an admin send information about the order to certain persons listed that order. Each person has language set and that is the language the message is supposed to be sent in. A short version of what I'm using: from django.utils.translation import ugettext as _ from django.core.mail import EmailMessage lang = method_that_gets_customer_language() body = _("Dear mister X, here is the information you requested\n") body += some_order_information subject = _("Order information") email = EmailMessage(subject, body, '[email protected]', ['[email protected]']) email.send() The customer information about the language he uses is available in lang. The default language is en-us, the translations are in french (fr) and german (de). Is there a way to use the translation for the language specified in lang for body and subject then switch back to en-us? For example: lang is 'de'. The subject and body should get the strings specified in the 'de' translation files.

  • RadioGroup getValue does not return correct slected value

    - by vagabond
    I'm running into a small issue with RadioGroup. My RadioGroup has possible values, true and false. The Radio types I have in my radiogroup use a Model that stores true or false. On an ajax onchange event I want to do some handling, and to do so I need to know the selected radio in my radiogroup and another identical radiogroup. The problem is getValue() only returns the initial value from my Pojo. Whenver I click on a radio button to change the selected Radio getValue() still returns the initial value. When I save my changes, my Pojo gets the correct value. I am finding this bizarre and have spent hours trying to figure our what I'm missing.

  • Is there any framework for Windows Forms, DB driven application development/prototyping?

    - by dolzenko
    I'm writing simple database driven application, 80% of functionality is CRUD operations on about 15 tables. Coming from web development background I figured I can cover almost all of these CRUD cases with Rails scaffolding or say Django admins. So I started to look around for Rails/Django-like framework but for Windows Forms applications (ofcourse I understand that "rich client" application development significantly differs from a web development and I'm not expecting anything really similar). I was surprised that except for a variety of ORMs (let's call it Model-layer) it seems like I'm left with little choice when it comes to View-Controller layer. Maybe I'm missing something? PS. I evaluated Visual Studio DataSet Designer, but it seems to work only for the most simple cases, and requires additional code for any slightly nontrivial task. (added) so far I've found: TrueView for .NET (thanks to Vijay Patel) NConstruct

  • API to determine whether running on iPhone or iPad

    - by Eric
    Is there an API for checking at runtime whether you are running on an iPhone or an iPad? One way I can think of would be to use: [[UIDevice currentDevice] model]; And detect the existence of the string @"iPad" - which seems a bit fragile. In the 3.2 SDK, I see that UIDevice also has a property which is really what I'm looking for, but doesn't work for pre-3.2 (obviously): [[UIDevice currentDevice] userInterfaceIdiom]; Are there other ways than checking for the existence of @"iPad" for a universal app?

  • why isn't my id showing up in django admin list?

    - by FurtiveFelon
    Hi all, I have a class Task(models.Model), and i didn't define id field explicitly (since it defines automatically for you). I checked in the database, it exists for the Task. Now i would like to display it in the list via list_display property in admin.ModelAdmin. I have a bunch of things in there, only id is not showing up for any of the rows i have. Everything else works fine. Anyone know anything special i have to do to get id to display? Thanks a lot! Jason

  • dojo 1.4: difference in tree html rendering

    - by Fell
    Hi, I have written an application using dojo 1.3 in which i have used the dijit tree. I am loading the tree with json data specified in the store which is in turn used by the tree model. In the 1.3 version the tree elements pick up the id directly from the json data.However in 1.4 the tree elements have their own id which is something like dijit__treenode_4. The id's that I have specified in json are unique and im not able to understand why these are not being used anymore. Please help me understand how this functionality has changed and how I can override the automatic id generation.. Thanks in advance, Fell

  • Is there a .NET BCL class to help with hand-rolled property path binding?

    - by Wayne
    WPF and Silverlight have a data binding model whereby I can provide a Binding with a Path which comprises a dot-notation of property accessors down from a DataContext to a specific value inside a complex object graph (eg. MyDataContext.RootProperty.SubProperty.Thing.Value) I have a (non-UI) requirement to accept such a path expressed as a simple string, and to use reflection on an object which is (hopefully) of a type which exposes the right property getters and setters in order to read and/or write values to those properties. Before I go off and start writing the parser and reflection code, is there a handy Framework 3.5 BCL class to help with this?

Now I want to know if I can get a copy of Android 1.6 or higher and put it on this device. I have looked on google, Torrent sites and ebay, but cannot find a copy of Android OS

  • Looking for some Feedback on a DB Design

    - by zSysop
    I'm currently working on a ticketing system which allows our users to submit tickets based on their own needs. i.e. if Department "A" is submitting a ticket they can have certain types of problem categories (such as "Supplies" or "Printer") along with details pertaining to the chosen category. I have laid out a partial db design and i was looking for some feedback on it. I've never built a system from the ground up by myself so i'm a little bit nervous. here's my a draft version of my db design Issues Table Id | CreatedBy | CreateDate | Status | Owner | AssignedTo | AssignmentDate | ----------------------------------------------------------------------------- EquipmentIssueDetails Table Id | IssueId | Serial # | Make | Model | .... --------------------------------------------- SupplyIssueDetails Table Id | IssueId | SupplyId | ItemId | QTY | UnitOfMeasurement ------------------------------------------------------------- NetworkIssueDetails Table Id | IssueId | Supervisor | Details | ------------------------------------------------------------- Notes Table Id | IssueId | Note | CreatedBy | CreateDate ------------------------------------------------------------- Thanks in advance

  • validate constructor arguments or method parameters with annotations, and let them throw an exceptio

    - by marius
    I am validating constructor and method arguments, as I want to the software, especially the model part of it, to fail fast. As a result, constructor code often looks like this public MyModelClass(String arg1, String arg2, OtherModelClass otherModelInstance) { if(arg1 == null) { throw new IllegalArgumentsException("arg1 must not be null"); } // further validation of constraints... // actual constructor code... } Is there a way to do that with an annotation driven approach? Something like: public MyModelClass(@NotNull(raise=IllegalArgumentException.class, message="arg1 must not be null") String arg1, @NotNull(raise=IllegalArgumentException.class) String arg2, OtherModelClass otherModelInstance) { // actual constructor code... } In my eyes this would make the actual code a lot more readable. In understand that there are annotations in order to support IDE validation (like the existing @NotNull annotation). Thank you very much for your help.

  • DisplayName attribute from Resources?

I'd like to do something like this: public class MyModel { [Required] [DisplayName(Resources.Resources.labelForName)] public string name{ get; set; } } But I can't to it, as the compiler says: "An attribute argument must be a constant expression, typeof expression or array creation expression of an attribute parameter type" :( Are there any workarounds? I am outputting labels manually, but I need these for the validator output!
