  • ASP MVC View Content as JSON

    - by Craig
    I have a MVC app with quite a few Controller Actions that are called using Ajax (jQuery) and return partial views content which updates a part of the screen. But what I would rather do is return JSON something like this. return Json(new { Result = true, Message = "Item has been saved", Content = View("Partial") }); Where the HTML is just a property of the Json. What this means is I need to retrieve the HTML that is rendered by the View method. Is there any easy way to do this, a few examples I have seen are quite convoluted. Edit: This question was originally for ASP.NET MVC 1, but if version 2 makes it easier I would like to hear the answer.

  • Loading a UIDatePicker in Landscape on a UINavigationController

    - by Ryan
    I have a custom UINavigationController that supports auto-rotate. I also have a UIDatePicker on one of my views that I throw onto the stack of the Navigation controller. The auto-rotate works if I start the date picker view in portrait and then rotate it. If I try load the date picker view in landscape to begin with, the view is all messed up. It looks like it would if it didn't support rotation and the frame only has about half of the picker visible and off center. I've tried making my own date picker that supports auto-rotate in case that was the problem, I've tried creating two different views and swapping them out, and I've tried changing the view frame size on the ViewWillAppear method. None of them seem to be working for me as of yet. Anyone have any suggestions on how to get the date picker to show up in landscape correctly on a navigation controller? I probably am overlooking something simple and the answer is right in front of me, but I'm not finding it.

  • UISearchbar clearButton forces the keyboard to appear

    - by DASKAjA
    I have a UISearchBar which acts as a live filter for a table view. When the keyboard is dismissed via endEditing:, the query text and the gray circular "clear" button remain. From here, if I tap the gray "clear" button the keyboard reappears as the text is cleared. How do I prevent this? If the keyboard is not currently open I want that button to clear the text without reopening the keyboard. There is a protocol method that gets called when I tap the clear button. But sending the UISearchBar a resignFirstResponder message doesn't have any effect on the keyboard.

  • How to mock a RIA service

    - by Budda
    Is there any ability to mock methods that are provided with RIA Services? I would like to test my Silverlight App without communication to the server side... I see a following approach: create a separate interface; add it to "base classes" for my RiaService; define each autogenerated RIA-method in this interface; insert dependency so that my "functionality" will depend not from the RiaService, but from the interface that is implemented with RiaService. But for this case I see a problem: how to keep my interface in the auto-generated files? ANy thoughts are welcome.

  • Where are config files for class libraries physically located?

    - by BadNinja
    My guess is that this question will fall under the category of "duh", but, nevertheless, I'm confused. When using config files in, for example, a Windows Forms Application, the config file can be found in C:\Program files\CompanyName\ProductName\Application.exe.config. However, with the class library I'm developing I do not see a "ClassLibrary.dll.config" file in the install folder after installing it (in tandem with another project) from Visual Studio. Even though I do not see the file anywhere, retrieving data from it works correctly. Plus, running the following code from a method within the class library returns the path you would expect: C:\Program files\CompanyName\ProductName\ClassLibrary.dll.config. If someone could shed some light on what I'm missing here, that would be really awesome. public static string MyMethod() { Assembly assem = Assembly.GetExecutingAssembly(); Configuration config = ConfigurationManager.OpenExeConfiguration(assem.Location); return "The assembly location was: " + assem.Location + Environment.NewLine + "The config file path was: " + config.FilePath; // Gives me "C:\Program files\CompanyName\ProductName\ClassLibrary.dll.config" }

  • Ho to launch Choose File dialog on Mac

    - by Manish
    Hi All, I am using LSOpenItemsWithRole() to open any file from my appication. It works fine for all files which has a default application to get opened on Mac, but for the files which cannot be open with any default application this method returns an error kLSApplicationNotFoundErr and does nothing. For such cases I want my application to launch the "Choose Application" dialog box, so that end user can choose any application from there to open the file. This dialog box pops up whenever any such file is directly opened by double clickig. Is there is any direct API call to do the same? any help will be appreciated, Thanks in advance! Manish

  • Why does my UITableView change from UITableViewStyleGrouped to UITableViewStylePlain

    - by casper
    My application has a view controller that extends UITableViewController. The initialization method looks like this: - (id)initWithCoder:(NSCoder*)coder { if (self = [super initWithCoder:coder]) { self.tableView = [[UITableView alloc] initWithFrame:self.tableView.frame style:UITableViewStyleGrouped]; } return self; } When the view is initially loaded, it's displayed as UITableViewStyleGrouped. However, if my app ever receives a low memory warning, the above view changes to UITableViewStylePlain. There is no associated xib file with the View/Controller. The viewDidUnload and didReceiveMemoryWarning methods are straightforward: - (void)didReceiveMemoryWarning { // Releases the view if it doesn't have a superview. [super didReceiveMemoryWarning]; // Release any cached data, images, etc that aren't in use. } - (void)viewDidUnload { // Release any retained subviews of the main view. // e.g. self.myOutlet = nil; } My question is, why does the table style change when I receive a memory warning?

  • MVC architectural question - Where should payment processing go?

    - by Keltex
    This question is related to my ASP.NET MVC 2 development, but it could apply to any MVC environment and a question of where the logic should go. So let's say I have a controller that takes an online payment such as a shopping cart application. And I have the method that accepts the customers' credit card information: public class CartController : Controller CartRepository cartRepository = new CartRepository() [HttpPost] public ActionResult Payment(PaymentViewModel rec) { if(!ModelState.IsValid) { return View(rec); } // process payment here return RedirectToAction("Receipt"); } At the comment process payment here should the payment processing be handled: In the controller? By the repository? Someplace else?

  • OutOfMemoryError trying to upload to Blobstore locally

    Hi all, I am trying to set up a basic file upload to blobstore, but I get this OutOfMemoryError: WARNING: Error for /_ah/upload/ aghvbWdkcmVzc3IcCxIVX19CbG9iVXBsb2FkU2Vzc2lvbl9fGMACDA java.lang.OutOfMemoryError: Java heap space at java.util.Arrays.copyOf(Arrays.java:2786) at java.io.ByteArrayOutputStream.write(ByteArrayOutputStream.java:71) at javax.mail.internet.MimeMultipart.readTillFirstBoundary(MimeMultipart.java: 316) at javax.mail.internet.MimeMultipart.parse(MimeMultipart.java:186) at javax.mail.internet.MimeMultipart.getCount(MimeMultipart.java:109) at com.google.appengine.api.blobstore.dev.UploadBlobServlet.handleUpload(UploadBlobServlet.java: 135) at com.google.appengine.api.blobstore.dev.UploadBlobServlet.access $000(UploadBlobServlet.java:72) at com.google.appengine.api.blobstore.dev.UploadBlobServlet $1.run(UploadBlobServlet.java:100) at java.security.AccessController.doPrivileged(Native Method) at com.google.appengine.api.blobstore.dev.UploadBlobServlet.doPost(UploadBlobServlet.java: 98) at javax.servlet.http.HttpServlet.service(HttpServlet.java:713) at javax.servlet.http.HttpServlet.service(HttpServlet.java:806) at org.mortbay.jetty.servlet.ServletHolder.handle(ServletHolder.java: 511); I used the Memory Analyzer on Eclipse and it said that the memory leak suspect is QueuedThreadPool.

  • Understanding how to inject object dependencies

    - by Hans
    I have an object that loads an instance of another object in a method. $survey = new survey; $question = new question($survey); $question-load($question_id); class question { public function __construct(&$survey) { $this-survey = $survey; } public function load ($id) { // now a question is loaded // want to load the survey that this question is in $this->survey->load($this->get('survey_id')); // ** survey_id is a field in the questions table // now $this->survey object has all the info about the survey this question is in } private function get($name) { // returns $name, if isset() from array that load() sets } } This is frying my brain, though, because it seems like $survey should come into $response already being a complete object. But, how do I do that, if I don't know what survey_id to load until I'm in the object? I am revamping a site and the most complex part is littered with this issue. TIA - Hans.

  • ctags doesn't work when class is defined like "class Gem::SystemExitException"

    - by dan
    You can define a class in a namespace like this class Gem class SystemExitException end end or class Gem::SystemExitException end When code uses first method of class definition, ctags indexes the class definition like this: SystemExitException test_class.rb /^ class SystemExitException$/;" c class:Gem With the second way, ctags indexes it like this: Gem rubygems/exceptions.rb /^class Gem::SystemExitException < SystemExit$/;" c The problem with the second way is that you can't put your cursor (in vim) over a reference to "Gem::SystemExitException" and have that jump straight to the class definition. Your only recourse is to page through all the (110!) class definitions that start with "Gem::" and find the one you're looking for. Does anyone know of a workaround? Maybe I should report this to the maintainer of ctags?

  • How to zoom in google map (J2ME)

    - by Nivek
    Hi all, I am trying to develop a J2ME application that could retrieve the google map by passing in the GPS coordinates. From http://wiki.forum.nokia.com/index.php/Google_Maps_API_in_Java_ME, it provides the Utility method for map scrolling. Basically it states that i need to include MicroFloat library in my project. Here's what i did (Not sure if i am doing it right) Create a project, build the code. Add the jar file into my current project lib. but i am still getting error from codes. Example double LToY(double y) { return Math.round( offset - radius * Double.longBitsToDouble(MicroDouble.log( Double.doubleToLongBits( (1 + Math.sin(Math.toRadians(y))) / (1 - Math.sin(Math.toRadians(y))) ) )) / 2); } Am i missing any import statment??? Btw i am using netbeans 6.5. Thanks for any guidance... Kevin

  • Android View.onDraw() always has a clean Canvas

    - by CaseyB
    I am trying to draw an animation. To do so I have extended View and overridden the onDraw() method. What I would expect is that each time onDraw() is called the canvas would be in teh state that I left it in and I could choose to clear it or just draw over parts of it (This is how it worked when I used a SurfaceView) but each time the canvas comes back already cleared. Is there a way that I can not have it cleared? Or maybe save the previous state into a Bitmap so I can just draw that Bitmap and then draw over top of it?

  • PHP: How to cast object to inherited class?

    - by andreyvlru
    I'd like to inherit PDOStatement class and use it in my website scripts. But I am frustrated how to get required object. PDO::query returns only direct PDOStatement object and looks like there are no other method to create PDOStatement object or inherited class. Initially i thought to move PDOStatement object to constructor of inherit class Something like that: $stmt = PDO -> query("select * from messages"); $messageCollection = new Messaging_Collection($stmt); But how to make instance of PDOStatement to inherited object (Messaging_Collection). It is a big question for me. class Messaging_Collection extends PDOStatement { public function __construct(PDOStatement $stmt) { //there i should to transform $stmt to $this // direct $this = $stmt is not possible // is there other right way? }

  • SQL Azure and VS 2010B2 or SSMSE 2008

    - by Vulgrin
    Ok, I see that people have asked this question before, but I'm seeing some conflicting statements. Can I, or can I not, connect directly to my SQL Azure database from SSMSE 2008? I see posts from before November that the SSMS 2008 RC would be able to connect directly - so I don't understand why the newest SSMSE cannot connect. Is it just a problem with the Express version of SSMS? Where can I find the "non-Express" version, if there is one? I can connect to the database via the cancel and connect method - however, you don't get object explorer that way. I see that there are add-ons for VS.Net to allow you to explore the database but I wanted to do it with the base apps if possible. Thanks

Has anyone got the email function working ?

  • Triggering shouldStartLoadWithRequest with multiple window.location.href calls

    - by AlBeebe
    Im trying to pass multiple things from a webpage inside a UIWebView back to my iPhone app via the shouldStartLoadWithRequest method of the UIWebView. Basically my webpage calls window.location.href = "command://foo=bar" and i am able to intercept that in my app no problem. Now if i create a loop and do multiple window.location.href calls at once, then shouldStartLoadWithRequest only appears to get called on once and the call it gets is the very last firing of window.location.href at the end of the loop. The same thing happens with the webview for Android, only the last window.location.href gets processed.

  • How can I prevent IIS from trying to load a dll?

    - by Abtin Forouzandeh
    My project is a Speech Server application using Windows Workflow. It runs as an app under IIS. It supports a plug-in system. Here is what is happening: Load DLL into memory and set the type on an InvokeWorkflow control. When the InvokeWorkflow control runs, it appears to correctly instantiate the workflow from the loaded assembly - it completes the Initialize method. Everything crashes an burns, the target workflow is never executed. I can resolve this by putting a copy of the DLL in the application's executing directory. The workflow then executes correctly So it appears that IIS is trying to reload the assembly, even though its already in memory. Is there anyway to alter or disable this behavior in IIS? Perhaps a hook I can write that will intercept the request to load the dll and use my own logic to do so?

  • Archiving an Entire Rails Site

    - by Pygmalion
    I have a Ruby on Rails site that was only needed for a short period of time during which users added various objects to a mySQL database, commenting on them, associating themselves with them, etc. etc. etc. The question is this: the site is no longer needed until a week next year around this time when I will clear the database and use it again (starting from scratch). What's the best way to archive the current site so that the existing content is still viewable but no new content can be added? By best way, I mean the method by which the least system resources will be used, the server will be the safest, etc. Any suggestions?

  • iPhone SDK: CLocationAccuracy. What constants map to what positioning technology?

    - by buzzappsoftware
    With respect to CLocationManager docs.... Constant values you can use to specify the accuracy of a location. extern const CLLocationAccuracy kCLLocationAccuracyBestForNavigation; extern const CLLocationAccuracy kCLLocationAccuracyBest; extern const CLLocationAccuracy kCLLocationAccuracyNearestTenMeters; extern const CLLocationAccuracy kCLLocationAccuracyHundredMeters; extern const CLLocationAccuracy kCLLocationAccuracyKilometer; extern const CLLocationAccuracy kCLLocationAccuracyThreeKilometers; Given that, I have the following questions. What triangulation method (GPS, cell tower or wi-fi) corresponds to each accuracy level? Does iPhone SDK utilize Skyhook Wireless API? For kCLLocationAccuracyBestForNavigation, there is note stating the phone must be plugged in. Is this enforced or is it just warning the developer the battery is likely to drain quick from using the GPS receiver. Thanks in advance.

  • Has anyone combined soap.py or suds with python-ntlm?

    - by Chris R
    I'd like to replace an app's current (badly busted and crufty) cURL-based (cURL command-line based!) SOAP client with suds or soap.py. Trouble is, we have to contact an MS CRM service, and therefore must use NTLM. For a variety of reasons the NTLM proxy is a bit of a pain to use, so I'm looking into python-ntlm to provide that support. Can suds or soap.py be made to use this authentication method? If so, how? If not, any other suggestions would be fantastic.

  • In-Memory SQL-CE

    - by harley.333
    Is there a way to connect to a SQL-CE database as a stream? Specifically, our ASP.Net application builds small SDF at runtime for off-line needs. When the user is done with his off-line duties, he uploads the SDF and the application imports the new and updated data. No problems there. Currently, we're saving the uploaded SDF to the web-server's hard-drive and connecting to the file. Can we connect to the uploaded SDF without saving it to the hard-drive? We are using the DbProviderFactory.CreateConnection method, but we're open to suggestions.

  • What is the difference between Java RMI and JMS?

    - by Sanoj
    When designing an distributed application in Java there seams to be a few technologies that address the same kind of problem. I have briefly read about Java Remote Method Invocation and Java Message Service, but it is hard to really see the difference. Java RMI seams to be more tightly coupled than JMS because JMS use asynchronous communication, but otherwise I don't see any big differences. What is the difference between them? Is one of them newer than the other one? Which one is more common/popular in enterprises? What advantages do they have over eachother? When is one preferred over the other? Do they differ much in how difficult they are to implement? I also think that Web Services and CORBA address the same problem.
