  • Table View rotate, but not properly (shape change)

    - by Pencrace
    Hello everyone, Here is the thing. I have a ViewController which contain a view in full window. And the program run in landscape mode. I want to put an UITableView over the full screen view but only on right half part of the screen. So I add a UITableView in my view controller, I used the Interface Builder in order to set the Table View in the upper half of the screen so It will be on the right part in LandscapeLeft mode. I searched for on a lot of forum how to rotate my Table View. And so it does... except, It get stuck on the upper half of the landscape mode, it should stick on the right half. I'm not a iPhone coder since long, so I'm a bit confused on how to solve this problem. Do you have any idea on how to resize or make the TableView rotate properly. Thanks,

  • Rails - building an absolute url in a model's virtual attribute without url helper

    - by Nick
    I have a model that has paperclip attachments. The model might be used in multiple rails apps I need to return a full (non-relative) url to the attachment as part of a JSON API being consumed elsewhere. I'd like to abstract the paperclip aspect and have a simple virtual attribute like this: def thumbnail_url self.photo.url(:thumb) end This however only gives me the relative path. Since it's in the model I can't use the URL helper methods, right? What would be a good approach to prepending the application root url since I don't have helper support? I would like to avoid hardcoding something or adding code to the controller method that assembles my JSON. Thank you

  • Can I update an iOS Enterprise App in the background like an App Store app can?

    - by lehn0058
    I have an iOS enterprise app that we are wirelessly distributing to our devices. Currently the app polls our server once a day to see if there is an app update. If there is, we try to install it by having the app call the following code: NSURL *installUrl = [NSURL URLWithString:[NSString stringWithFormat:@"itms-services://?action=download-manifest&url=%@", plistUrl]]; [[UIApplication sharedApplication] openURL:installUrl]; This causes the app to prompt the user with an alert dialog to install the update. If they click install, the app closes and the update is downloaded and installed. I am wondering if there is anything for enterprise apps for iOS 7 similar to the AppStore's automatic updates? I would like to be able to update our app without the user having to press an update button and be able to update at a time when the user won't have to wait for it to install.

  • How do I prevent an ASP.NET MVC deployment on IIS 6.0, using wildcard mapping, from attempting to ha

    - by Rob
    As noted by the title, what is the best way to configure an IIS 6.0 deployment of an ASP.NET MVC application such that connections to hidden shares are ignored? The application in question is using wildcard mapping to allow for clean URLs since we are planning on upgrading to IIS 7.0 in the near future and we are also handling the caching and compression issues with a custom library so we would like to avoid turning wildcard mapping off unless absolutely necessary. Below is a one of the errors from the application to give you an example of what we are seeing. -------------------------------------------------------------------------------- System.Web.HttpException -------------------------------------------------------------------------------- Time Stamp - 03 Mar 2010, 08:11:44 Path - N/A, Internal Server Operation Message - The controller for path '/C$' could not be found or it does not implement IController.

  • Is it possible to bind data asynchronously between two dropdownlists in a view?

    - by user252160
    I'd like to achieve the following effect using ASP.NET MVC and JQuery. I've got a drop down list displaying a list of Countries. I want to make it so that when I change the value of the country, a new drop down list appears below it, showing a list of companies whose country of origin is the particular selected company. The thing is that I do not want to rely too much on controller actions because I'm using it in a Template Helper which is a "headless" view. Can I bind it somehow?

  • Ruby on Rails: reducing complexity of parameters in a RESTFul HTTP POST request (multi-model)

    - by randombits
    I'm using cURL to test a RESTFul HTTP web service. The problem is I'm normally submitting a bunch of values normally like this: curl -d "firstname=bob&lastname=smith&age=25&from=kansas&someothermodelattr=val" -H "Content-Type: application/x-www-form-urlencoded" http://mysite/people.xml -i The problem with this is my controller will then have code like this: unless params[:firstname].nil? end unless params[:lastname].nil? end // FINALLY @person = People.new(params[:firstname], params[:lastname], params[:age], params[:from]) etc.. What's the best way to simplify this? My Person model has all the validations it needs. Is there a way (assuming the request has multi-model parameters) that I can just do: @person = People.new(params[:person]) and then the initializer can take care of the rest?

  • Presenting MVC to Old C++ Spaghetti Coders?

    - by leeand00
    I wish to present the idea of MVC to a bunch of old C++ spaghetti coders (at my local computer club). One of them that has alot of influence on the rest of the group seems to finally be getting the idea of encapsulation (largely due in part to this website). I was hoping that I could also point him in the right direction by showing him Model View Controller, but I need to do it in a way that makes sense to him, as well as it probably needs to be written in C/C++! I realize that MVC is a very old architectural pattern so it would seem to me that there should be something out there that would do the job. I'm more of a web developer, so I was wondering if anybody out there who is a good C/C++ coder could tell me what it is that made the MVC light switch turn on in your head.

  • Determine which mouse was clicked (multiple mice devices) in .NET

    - by Morten K
    Hi, I want to detect when my touchpad is clicked! I normally use a usb mouse, so I don't use the touchpad for anything. Instead I'd like to make it possible to perform an action in .NET, when the touchpad is clicked. This way I can use it as a shortcut: One tap and something cool happens. Is this possible, and if yes, any clue how? I'd prefer if it could be working in VB.NET or C#. My theory is that I'd have to make a mousehook, which then somehow determines which device the click is coming from. If the click is determined to be from the touchpad, then cancel the click and doWhatever(). Thanks!

  • How do you deal with the conflict between ActiveSupport::JSON and the JSON gem?

    - by Luke Francl
    I am stumped with this problem. ActiveSupport::JSON defines to_json on various core objects and so does the JSON gem. However, the implementation is not the same -- the ActiveSupport version takes arguments and the JSON gem version doesn't. I installed a gem that required the JSON gem and my app broke. The issue is that I'm using to_json in a controller that returns a list of objects, but I want to control which attributes are returned. When code anywhere in my system does require 'json' I get this error message: TypeError: wrong argument type Hash (expected Data) I tried a couple of things that I read online to fix it, but nothing worked. I ended up re-writing the gem to use ActiveSupport::JSON.decode instead of JSON.parse. This works but it's not sustainable...I can't be forking gems every time I want to use a gem that requires the JSON gem. Update: The best solution of this problem is to upgrade to Rails 2.3 or higher, which fixed it.

  • Setting a property value on each of the results in a FetchedResults set

    - by RickiG
    Hi On my Core Data Entity "Book" i have a boolean property, 'wasViewed' (NSNumber numberWithBool) that tells me if the Book was "viewed". I would like to implement a sort of "reset" this property for all my NSManagedObjects "Book". So that I can set them all to NO between sessions. I use an NSPredicate to retrieve all the Books like this: NSPredicate *predicate = [NSPredicate predicateWithFormat:@"wasViewed == %@", [NSNumber numberWithBool:YES]]; // code for setting entity, request etc... NSMutableArray *mutableFetchResults = [[[managedObjectContext executeFetchRequest:request error:&error] mutableCopy] autorelease]; This is working just fine, however, now I need to set up a loop, go through each Book object, something like this: for(Book *b in mutableFetchResults) { [b setWasViewed:NO] } Is there a way to perform an action on each element that fits the predicate instead of retrieving it? So instead of executeFetchRequest on a managedObjectContext it could be executeOperationOnFetchRequestResults or something along those lines. Thanks for any input given:)

  • Track each request to the website using HttpModule

    - by stacker
    I want to save each request to the website. In general I want to include the following information: User IP, The web site url, user-if-exist, date-time. Response time, response success-failed status. Is it reasonable to collect the 1 and 2 in the same action? (like same HttpModule)? Do you know about any existing structure that I can follow that track every request/response-status to the website? The data need to be logged to sql server.

  • How to compare if string has a enter key in the end using jquery/javascript?

    - by user144842
    I have a string value from a user input box. I have to figure out if last char is a enter key (line feed). Thats the code. Here I am checking if last char has a whitespace. Now I also have to check if last char is enter key (carriage return or line feed). How can i do this? var txt = $get("<%= txtUserText.ClientID %>"); if (txt.value.substring(txt.value.length -1) !== ' ' || <checkifLastCharIsEnterKey>) //my code to take action **I don't think i need a keypress or keyup event because this above piece of code is not invoked at the time of user input.

  • Safe HttpContext.Current.Cache Usage

    - by Burak SARICA
    Hello there, I use Cache in a web service method like this : var pblDataList = (List<blabla>)HttpContext.Current.Cache.Get("pblDataList"); if (pblDataList == null) { var PBLData = dc.ExecuteQuery<blabla>( @"SELECT blabla"); pblDataList = PBLData.ToList(); HttpContext.Current.Cache.Add("pblDataList", pblDataList, null, DateTime.Now.Add(new TimeSpan(0, 0, 15)), Cache.NoSlidingExpiration, CacheItemPriority.Normal, null); } I wonder is it thread safe? I mean the method is called by multiple requesters And more then one requester may hit the second line at the same time while the cache is empty. So all of these requesters will retrieve the data and add to cache. The query takes 5-8 seconds. May a surrounding lock statement around this code prevent that action? (I know multiple queries will not cause error but i want to be sure running just one query.)

  • ASP.NET MVC - separating large app

    - by marc_s
    I've been puzzled by what I consider a contradiction in terms: ASP.NET MVC claims to be furthering and supporting the "separation of concern" motto, which I find a great idea. However, it seems there's no way of separating out controllers, model or views into their own assembly, or separating areas into assemblies. With the fixed Controller, Model and View folders in your ASP.NET MVC, you're actually creating a huge hodge podge of things. Is that the separation of concerns, really?? Seems like quite the contrary to me. So what I'm wondering: how can I create an ASP.NET MVC solution that will either separate out controllers, the model, and the folders full of views, into separate assemblies? how can I put areas of ASP.NET MVC 2 into separate assemblies? or how else do you manage a large ASP.NET MVC app - which has several dozen or even over a hundred controllers, lots of model and viewmodel classes, and several hundred views?

  • How come checkbox state is not always passed along to PHP script?

    - by George Edison
    I have an HTML form: <form action='process.php' method='post'> <input type='checkbox' name='check_box_1' /> Check me!<br> </form> Here is a section from the PHP script process.php: echo (isset($_POST['check_box_1']))?'Set':'Not set'; The output of the script when the checkbox is set is Set But when the checkbox is not set, the output is: Not set Why is this? This seems like a very poor design because my PHP script checks a number of $_POST variables to make sure they were passed along to the script. When the $_POST['check_box_1'] value is not set, then how do I know whether the script failed to pass along the value or the checkbox was just not set?

  • Query DNSBL or other block lists using PHP

    - by 55skidoo
    Is there any way to use PHP code to query a DNSBL (block list) provider and find out if the IP address submitted is a bad actor? I would like to take an existing IP address out of a registration database, then check whether it's a known block-listed IP address by performing a lookup on it, then if it's a blacklisted, do an action on it (such as, delete entry from registration database). Most of the instructions I have seen assume you are trying to query the blocklist via a mail server, which I can't do. I tried querying via web browser by typing in queries such as "58.64.xx.xxx.dnsbl.sorbs.net" but that didn't work.

  • UINavigationController Push Crash in Distribution but not Release

    - by Alavoil
    I have a UINavigationController that I will be pushing a new view onto from selection of a UITableView row. I have tested this feature in "Release" configuration and it works perfectly, however when I build for "Distribution" it crashes when trying to push the new view onto the stack. - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { /* irrelevant code */ DetailsViewController *detailController = [[DetailsViewController alloc] initWithNibName:@"DetailsViewController" bundle:nil]; detailController.name = tmpName; detailController.time = tmpTime; [self.navigationController pushViewController:detailController animated:YES]; return nil; } An exception is thrown on the line where the controller is pushed onto the stack. I have verified that the detailController is not nil. Again, this only happens in my "Distribution" build of the code. Any ideas?

  • UIViewController prevent view from unloading

    - by Ican Zilb
    When my iPhone app receives a Memory warning the views of UIViewControllers that are not currently visible get unloaded. In one particular controller unloading the view and the outlets is rather fatal. I'm looking for a way to prevent this view from being unloaded. I find this behavior rather stupid - I have a cache mechanism, so when a memory warning comes - I unload myself tons of data and I free enough memory, but I definitely need this view untouched. I see UIViewController has a method 'unloadViewIfReloadable', which gets called when the Memory Warning comes. Does anybody know how to tell Cocoa Touch that my view is not reloadable? Any other suggestions how to prevent my view from being unloaded on Memory Warning? Thanks in advance

  • Port C's fread(&struct,....) to Python

    - by user287669
    Hey, I'm really struggling with this one. I'am trying to port a small piece of someone else's code to Python and this is what I have: typedef struct { uint8_t Y[LUMA_HEIGHT][LUMA_WIDTH]; uint8_t Cb[CHROMA_HEIGHT][CHROMA_WIDTH]; uint8_t Cr[CHROMA_HEIGHT][CHROMA_WIDTH]; } __attribute__((__packed__)) frame_t; frame_t frame; while (! feof(stdin)) { fread(&frame, 1, sizeof(frame), stdin); // DO SOME STUFF } Later I need to access the data like so: frame.Y[x][y] So I made a Class 'frame' in Python and inserted the corresponding variables(frame.Y, frame.Cb, frame.Cr). I have tried to sequentially map the data from Y[0][0] to Cr[MAX][MAX], even printed out the C struct in action but didn't manage to wrap my head around the method used to put the data in there. I've been struggling overnight with this and have to get back to the army tonight, so any immediate help is very welcome and appreciated. Thanks

  • jQuery Flip! links inside divs

    - by JLee
    Hey there. I want to use Flip (http://lab.smashup.it/flip/) for one of my projects. But I want the links to make the flip action inside the divs that are going to be flipped. I stumbled across a question here and the reply was very helpful, and by using that codes I managed to achieve what I want. But now the issue is when the page first loads it automatically flips before clicking any link. I don't know much about jQuery. So I would appreciate any help.

  • "dynamic" keyword and JSON data

    - by Peter Perhác
    An action method in my ASP.NET MVC2 application returns a JsonResult object and in my unit test I would like to check that the returned JSON object indeed contains the expected values. I tried this: 1. dynamic json = ((JsonResult)myActionResult).Data; 2. Assert.AreEqual(JsonMessagesHelper.ErrorLevel.ERROR.ToString(), json.ErrorLevel); But I get a RuntimeBinderException "'object' does not contain a definition for 'ErrorLevel'". However, when I place a breakpoint on line 2 and inspect the json dynamic variable (see picture below), it obviously does contain the ErrorLevel string and it has the expected value, so if the runtime binder wasn't playing funny the test would pass. What am I not getting? What am I doing wrong and how can I fix this? How can I make the assertion pass?
