  • mvc action name in url

    - by Paul
    UPDATE: My model going into the save method is PartialViewModel, which in the save method, is pushed into the index's ContactViewModel and sent back. This wasn't clear. I am playing around with MVC3, and have a contact controller with a SaveDetails action. The index cshtml has a partial with a form whose action is pointing to this controller. When I submit the form not having completed it fully, thereby firing the validation, the url now contains the SaveDetails action name (http://localhost:7401/Contact/SaveDetails). The form code is: @using (Html.BeginForm("SaveDetails", "Contact")) { ... } The controller action looks like this: public ActionResult SaveDetails(Models.PartialsViewModel pvm) { return View("Index", new ContactViewModel{ PartialsViewModel = pvm } ); } What am I doing wrong?

  • GKSession sendDataToAllPeers including sendee?

    - by Typeoneerror
    I've got a number of devices connected over wifi using GameKit. I have a simple UIAlertView popping up when peers receive data. All but the sendee show this alert view when data is sent, so I'm wondering if that's a bug in my app or if that's expected behavior. Should call a method manually at the same on the sendee device? For example, if I wanted to send a "GameStart" packet to the 4 phones, the peers would call startGame: in the receiveData:fromPeer:inSession:context: method when it receives that packet and the sendee would just sendData and call startGame: on itself. Does that sound right or is there a way to include the sendee in the sendData list so that it responds exactly the same as all connected peers?

  • efficient way to detect if an image is empty

    - by Jos
    Hi, I need a very fast method to detect if an image is empty. Im my case then all pixels are white and transparant. The images are png's. My current method is to load them in a memory bitmap and check each pixel value, but this is way to slow. Is there a more efficient way? This is my current code: 'Lock the bitmap bits. Dim bmpData As System.Drawing.Imaging.BitmapData = bmp.LockBits(rectBmp, _ Drawing.Imaging.ImageLockMode.ReadOnly, bmp.PixelFormat) Try Dim x As Integer Dim y As Integer For y = 0 To bmpData.Height - 1 For x = 0 To bmpData.Width - 1 If System.Runtime.InteropServices.Marshal.ReadByte(bmpData.Scan0, (bmpData.Stride * y) + (4 * x) + 3) <> 0 Then Return True Exit For End If Next Next Finally bmp.UnlockBits(bmpData) End Try

  • WCF DataContract GetCustomDataToExport

    - by JeffN825
    I'm trying to get the default behavior for a client referencing my WCF WSDL to set IsReference to true on the imported DataContracts. It looks like I should be able to use an IDataContractSurrogate with GetCustomDataToExport to accomplish this...which specifcally means adding the following to the generated ComplexType in the xsd associated with the WSDL: <xs:attribute ref="ser:Id" /> <xs:attribute ref="ser:Ref" /> There is, of course no usable documentation I can find from MS about how to use this method. The MSDN page says it should return an object...but does not indicate at all what type of object this should be....how useless... Before I go reflector'ing for this, does anyone out there know how to use this method? Thanks.

  • Can't register credit card with Microsoft Windows Azure

    - by user1083268
    I get the following error when trying to sign up for the Microsoft Azure 90-day free trial: We can't authorize the payment method. Please make sure the information is correct, or use another payment method. If you continue to get this message, please contact your financial institution. I've tried three different cards, two credit and one debit. Those cards are issued from two different banks. I've also tried the cards on two separate accounts. Someone from my work also confirmed that he could not sign up for the free trial either. Has anyone else had this problem? I haven't really seen much help searching Google and the support staff doesn't seem interested in helping people sign up for free accounts.

  • Operator Overloading with C# Extension Methods

    - by Blinky
    I'm attempting to use extension methods to add an operater overload to the C# StringBuilder class. Specifically, given StringBuilder sb, I'd like sb += "text" to become equivalent to sb.Append("text"); Here's the syntax for creating an extension method for StringBuilder: public static class sbExtensions { public static StringBuilder blah(this StringBuilder sb) { return sb; } } It successfully adds the "blah" extension method to the StringBuilder. Unfortunately, operator overloading does not seem to work: public static class sbExtensions { public static StringBuilder operator +(this StringBuilder sb, string s) { return sb.Append(s); } } Among other issues, the keyword 'this' is not allowed in this context. Are adding operator overloads via extension methods possible? If so, what's the proper way to go about it?

  • C# Async call garbage collection

    - by Troy
    Hello. I am working on a Silverlight/WCF application and of course have numerous async calls throughout the Silverlight program. I was wondering on how is the best way to handle the creation of the client classes and subscribing. Specifically, if I subscribe to an event in a method, after it returns does it fall out of scope? internal MyClass { public void OnMyButtonClicked() { var wcfClient = new WcfClient(); wcfClient.SomeMethodFinished += OnMethodCompleted; wcfClient.SomeMethodAsync(); } private void OnMethodCompleted(object sender, EventArgs args) { //Do something with the result //After this method does the subscription to the event //fall out of scope for garbage collection? } } Will I run into problems if I call the function again and create another subscription? Thanks in advance to anyone who responds.

  • reloadData not working - suspect cell's reuseIdentifier

    - by retailevolved
    I have a view controller that gets presented modally and changes some data that effects the data in a uitableview in the modal's parent view controller (a table view). I call the tableview's reloadData method when the parent view reappears. I have confirmed that this code gets hit with a break point. My trouble is, reloadData isn't working. Here's the kicker - if I don't use reuseIdentifiers in the - (UITableViewCell *)cellForRowAtIndexPath:(NSIndexPath *)indexPath method, the data reloads correctly. It looks like the reuseIdentifier is to blame. I really want to continue to use the reuseIdentifier for my cells - how do I make this work?

  • C# how to dynamically cast an object?

    - by JL
    I am building a helper object that has a property called Mailer. In reality Mailer can be either a System.Net.Mail.MailMessage or a Mono.System.Net.Mail.MailMessage. So I would preferably only want 1 declaration of mailer. For example I don't want: private Mono.Mailing.MailMessage MonoMessage = new Mono.Mailing.MailMessage(); private System.Net.Mail.MailMessage MailMessage = new System.Net.Mail.MailMessage(); I would prefer object mailer; Then in constructor switch (software) { case EnunInternalMailingSoftware.dotnet: this.mailer = new System.Net.Mail.MailMessage(); break; case EnunInternalMailingSoftware.mono: this.mailer = new Mono.Mailing.MailMessage(); break; } The problem is that mailer has no properties at design time. So I can't compile my code. How can this be fixed, am I taking the right approach. Thanks in advance

  • How do I alternate table row colors in asp.net mvc using jquery?

    - by grenade
    Probably a dumb question but I'm new to MVC and jQuery. I want to alternate the row colors of my tables and I've decided that I'm going to use jQuery to do it. I know that I could write an extension method (http://haacked.com/archive/2008/08/07/aspnetmvc_cycle.aspx), etc but after reading SH's comment on the article at http://haacked.com/archive/2008/05/03/code-based-repeater-for-asp.net-mvc.aspx I've picked jQuery as the solution I want to implement. I want to implement the method described at http://www.packtpub.com/article/jquery-table-manipulation-part2 but I haven't figured out where to put the initial jQuery call (eg: $(document).ready(function() {...}); Like I said, I'm new to jQuery...

  • google contacts api service account oauth2.0 sub user

    - by user3709507
    I am trying to use the Google Contacts API to connect to a user's contact information, on my Google apps domain. Generating an access_token using the gdata api's ContactsService clientlogin function while using the API key for my project works fine, but I would prefer to not store the user's credentials, and from the information I have found that method uses OAuth1.0 So, to use OAuth2.0 I have: Generated a Service Account in the developer's console for my project Granted access to the service account for the scope of https://www.google.com/m8/feeds/ in the Google apps domain admin panel Attempted to generate credentials using SignedJwtAssertionCredentials: credentials = SignedJwtAssertionCredentials( service_account_name=service_account_email, private_key=key_from_p12_file, scope='https://www.google.com/m8/feeds/', sub=user_email') The problem I am running into is that attempting to generate an access token using this method fails. It succeeds in generating the token when I remove the sub parameter, but then that token fails when I try to fetch the user's contacts. Does anyone know why this might be happening?

  • resetting the image in an NSView

    - by Josan
    I think this is a very simple question, but I’m new to programming so I may be going about it in a wrong-headed way. I have a basic understanding of Objective-C writing terminal applications and am teaching myself how to use the Cocoa GUI. I understand how to use IBOutlet and IBAction to connect a simple button to a method that will repeatedly send random numbers to a textfield . I understand how to add a NSView file, connect it to a custom view in interface builder and draw a path through random points in the view when the application launches. (I’ve been putting this code inside the - (void)drawRect:(NSRect)dirtyRect method that is declared when the file is created). What I can’t seem to figure out is how to connect a button to an action that will then ‘refresh’ the view – in this case repopulate it with another set of random points connected with a path. Looking at the documentation, I think I should somehow be using – (void) setNeedsDisplay(BOOL)flag but nothing I have tried so far had worked. Please tell me, what am I missing here?

  • What's the proper way to use sqlite on the iPhone?

    - by Elliot Chen
    Hi, Experts: Can you please give some suggestions on sqlite using on the iPhone? Within my application, I use a sqlite DB to store all local data. Two methods can be used to retrieve those data during running time. 1, Load all the data into memory at initialization stage. (More memory used, less DB open/close operation needed) 2, Read corresponding records when necessary, free the occupied memory after using. (Good habit for memory using, but much DB open/close operations needs). I prefer to use method 2, but not sure whether too many DB opening/closing operations could affect app's efficiency. Or do you think I can 'upgrade' method 2 by opening DB when app launches and closing DB when app quits? Thanks for your suggestions very much!

  • searching map by value

  • Rails: Ajax-enabled form without a model object

    - by Caffeine Coma
    I'm new to Rails and having a hard time figuring out how to create a form that submits over Ajax without having a corresponding model object. My use case is a simple form that collects an email address and sends it an email; there's nothing to be persisted, so no model. In cases where I do have a model, I've had success with form_for(@model, remote: true). I can't seem to find the right helper for the case where there is no model. I tried form_tag(named_path, remote: true) and that works, but does not use Ajax. Pointers to an example with an example with a proper controller, .html.erb and routes.rb would be really appreciated.

  • interfacing: simplified

    - by code wombat
    i've been doing some research on interfaces and a simple layman's explanation for what it truly is. For some reason people love using overly complex explanations and jargon to explain truly simple concepts (guess it makes them feel big) and i have a gut feeling it's the same in this case. so from what i could grasp, it seems like interfaces are nothing more than a way to reserve method names, their return type if any, and the type and amount of arguments they accept. so when a class implements an interface (or interfaces) it is forced to define the body of each method from the interface(s). Am i on the nose with this one or do i need to keep digging? p.s. i know javascript doesn't have support for interfaces, but i still need to understand the concept because there are quite a few places where it's shown how to emulate to an extent.

  • Issues using UITapGestureRecognizers in Interface Builder

    - by 5StringRyan
    I'm attempting to use the UITapGestureRecognizer object that can be found in Interface Builder. I've dragged a single "UITapGestureRecognizer" from the object library to a single view xib. I then create an IBAction method from this tap gesture, for a simple test, I'm just printing an "NSLog" message to the console once there is a tap on the view. I've run this, and the tap method isn't being called. I right click the view in IB and I noticed that there is a warning "!" on the view's "Outlook Collections" I see: Outlook Collections gestureRecognizers - Tap Gesture Recognizer (!) The warning states: UIView does not have an outlet collection named gestureRecognizers. What do I need to do to remedy this?

    I would like to update a list item using SharePoint and am stuggling to find 1 decent CAML example. Here is what I want to do, in SQL my query would look something like this update [table] set field='value' where fieldID = id; so this would mean I have 1 item in a list I would like to update 1 field on given the ID of that listitem.

  • iPhone app launch times and Core Data migration

    - by sehugg
    I have a Core Data application which I plan to update with a new schema. The lightweight migration seems to work, but it takes time proportional to the amount of data in the database. This occurs in the didFinishLaunchingWithOptions phase of the app. I want to avoid <app> failed to launch in time problems, so I assume I cannot keep the migration in the didFinishLaunchingWithOptions method. I assume the best method would involve performing the migration in a background thread. I assume also that I'd need to defer loading of the main ViewController until the loading completes to avoid using the managedObjectContext until initialization completes. Does this make sense, and is there example code (maybe in Apple sample projects) of this sort of initialization?

  • Php plugin to replace '->' with '.' as the member access operator ? Or even better: alternative synt

    - by Gigi
    Present day usable solution: Note that if you use an ide or an advanced editor, you could make a code template, or record a macro that inserts '->' when you press Ctrl and '.' or something. Netbeans has macros, and I have recorded a macro for this, and I like it a lot :) (just click the red circle toolbar button (start record macro),then type -> into the editor (thats all the macro will do, insert the arrow into the editor), then click the gray square (stop record macro) and assign the 'Ctrl dot' shortcut to it, or whatever shortcut you like) The php plugin: The php plugin, would also have to have a different string concatenation operator than the dot. Maybe a double dot ? Yea... why not. All it has to do is set an activation tag so that it doesnt replace / interpreter '.' as '->' for old scripts and scripts that dont intent do use this. Something like this: <php+ $obj.i = 5 ?> (notice the modified '<?php' tag to '<?php+' ) This way it wouldnt break old code. (and you can just add the '<?php+' code template to your editor and then type 'php tab' (for netbeans) and it would insert '<?php+' ) With the alternative syntax method you could even have old and new syntax cohabitating on the same page like this (I am illustrating this to show the great compatibility of this method, not because you would want to do this): <?php+ $obj.i = 5; ?> <?php $obj->str = 'a' . 'b'; ?> You could change the tag to something more explanatory, in case somebody who doesnt know about the plugin reads the script and thinks its a syntax error <?php-dot.com $obj.i = 5; ?> This is easy because most editors have code templates, so its easy to assign a shortcut to it. And whoever doesnt want the dot replacement, doesnt have to use it. These are NOT ultimate solutions, they are ONLY examples to show that solutions exist, and that arguments against replacing '->' with '.' are only excuses. (Just admit you like the arrow, its ok : ) With this potential method, nobody who doesnt want to use it would have to use it, and it wouldnt break old code. And if other problems (ahem... excuses) arise, they could be fixed too. So who can, and who will do such a thing ?
