  • Why doesn't my viewmodel properties get populated

    - by Jakob
    Hi. I've looked all over and I can't figure out why my viewmodel doesn't get populated. I have this code: Followers = new ObservableCollection<aspnet_User>(_followersRepo.aspnet_Users); _followersRepo.Load(_followersRepo.GetUsersFollowingIDQuery(CurrentUserId)); Following = new ObservableCollection<aspnet_User>(_followingRepo.aspnet_Users); _followingRepo.Load(_followingRepo.GetUsersFollowedByIDQuery(CurrentUserId)); CurrentUser = _fullUserRepo.FullUsers.SingleOrDefault(); _fullUserRepo.Load(_fullUserRepo.GetFullUserByIDQuery(CurrentUserId)); But when I debug, there is no data loaded to the Followers, Following and CurrentUser objects. I know that data should be returned because I'm trying to implement the MVVM pattern in my app, and haven't changed the domainservice. Also I can se debugging the CurrentUserId has a value.

  • How to give properties to c++ classes (interfaces)

    - by caas
    Hello, I have built several classes (A, B, C...) which perform operations on the same BaseClass. Example: struct BaseClass { int method1(); int method2(); int method3(); } struct A { int methodA(BaseClass& bc) { return bc.method1(); } } struct B { int methodB(BaseClass& bc) { return bc.method2()+bc.method1(); } } struct C { int methodC(BaseClass& bc) { return bc.method3()+bc.method2(); } } But as you can see, each class A, B, C... only uses a subset of the available methods of the BaseClass and I'd like to split the BaseClass into several chunks such that it is clear what it used and what is not. For example a solution could be to use multiple inheritance: // A uses only method1() struct InterfaceA { virtual int method1() = 0; } struct A { int methodA(InterfaceA&); } // B uses method1() and method2() struct InterfaceB { virtual int method1() = 0; virtual int method2() = 0; } struct B { int methodB(InterfaceB&); } // C uses method2() and method3() struct InterfaceC { virtual int method2() = 0; virtual int method3() = 0; } struct C { int methodC(InterfaceC&); } The problem is that each time I add a new type of operation, I need to change the implementation of BaseClass. For example: // D uses method1() and method3() struct InterfaceD { virtual int method1() = 0; virtual int method3() = 0; } struct D { int methodD(InterfaceD&); } struct BaseClass : public A, B, C // here I need to add class D { ... } Do you know a clean way I can do this? Thanks for your help edit: I forgot to mention that it can also be done with templates. But I don't like this solution either because the required interface does not appear explicitly in the code. You have to try to compile the code to verify that all required methods are implemented correctly. Plus, it would require to instantiate different versions of the classes (one for each BaseClass type template parameter) and this is not always possible nor desired.

  • How to disable listbox auto select item when pressing key

    - by tomfox66
    I have a listbox where I want to copy and paste items within that listbox. Copy and paste works fine but everytime I press "Crtl + C" the item starting with the letter C is automatically selected. Can this automatic selection be disabled or am I missing something here Here is the copy and paste method I implemented: private void listBox_Script_KeyDown(object sender, KeyEventArgs e) { if (e.Control == true && e.KeyCode == Keys.C) { int test = listBox_Script.SelectedIndex; Clipboard.SetDataObject(listBox_Script.Items[listBox_Script.SelectedIndex], true); return; } if (e.Control == true && e.KeyCode == Keys.V) { if (Clipboard.GetDataObject().GetDataPresent(DataFormats.Text)) { listBox_Script.Items.Insert(listBox_Script.SelectedIndex + 1, Clipboard.GetDataObject().GetData(DataFormats.Text).ToString()); return; } }

  • Objective-C property getter

    - by Daniel
    What is technically wrong with the following: @property(nonatomic, assign) NSUInteger timestamp; @property(nonatomic, readonly, getter = timestamp) NSUInteger startTime; @property(nonatomic, assign) NSUInteger endTime; I am sure I can find a better way to organise this, but this is what I ended up with at one point in my project and I noticed that accessing the startTime property always returned 0, even when the timestamp property was set to a correct timestamp. It seems having set the getter of startTime to an existing property (timestamp), it is not forwarding the value of timestamp when I do: event.startTime => 0 event.timestamp => 1340920893 All these are timestamps by the way. Just a reminder, I know the above should have happened in my project but I don't understand why accessing startTime doesn't forward onto timestamp property. UPDATE In my implementation I am synthesising all of these properties: @synthesize timestamp, endTime, startTime; Please check an example object to use that demonstrates this at my gist on GitHub: https://gist.github.com/3013951

  • Javascript object properties access functions in parent constructor?

    - by Bob Spryn
    So I'm using this pretty standard jquery plugin pattern whereby you can grab an api after applying the jquery function to a specific instance. This API is essentially a javascript object with a bunch of methods and data. So I wanted to essentially create some private internal methods for the object only to manipulate data etc, which just doesn't need to be available as part of the API. So I tried this: // API returned with new $.TranslationUI(options, container) $.TranslationUI = function (options, container) { // private function? function monkey(){ console.log("blah blah blah"); } // extend the default settings with the options object passed this.settings = $.extend({},$.TranslationUI.defaultSettings,options); // set a reference for the container dom element this.container = container; // call the init function this.init(); }; The problem I'm running into is that init can't call that function "monkey". I'm not understanding the explanation behind why it can't. Is it because init is a prototype method?($.TranslationUI's prototype is extended with a bunch of methods including init elsewhere in the code) $.extend($.TranslationUI, { prototype: { init : function(){ // doesn't work monkey(); // editing flag this.editing = false; // init event delegates here for // languagepicker $(this.settings.languageSelector, this.container).bind("click", {self: this}, this.selectLanguage); } } }); Any explanations would be helpful. Would love other thoughts on creating private methods with this model too. These particular functions don't HAVE to be in prototype, and I don't NEED private methods protected from being used externally, but I want to know how should I have that requirement in the future.

  • Monotouch auto resizing views in iphone

    - by Tim Bassett
    I have created a view in interface builder that contains another view (content area) and a button bar at the bottom. The hierarchy is as: ->View --->mapContainer UIView ----->map MKMapView ----->OverlayView UIView --->ToolBar UIToolBar I would like the mapContainer to resize to full window when the ToolBar is hidden. I would like the map and the OverlayView to resize to the mapContainer size I have attempted the following code, but it has no effect. Please advise? public override void ViewDidLoad () { base.ViewDidLoad (); this.mapContainer.AutosizesSubviews = true ; this.View.AutosizesSubviews = true ; try { this.mapContainer.AutoresizingMask = UIViewAutoresizing.FlexibleHeight | UIViewAutoresizing.FlexibleWidth ; this.map.AutoresizingMask = UIViewAutoresizing.FlexibleHeight | UIViewAutoresizing.FlexibleWidth ; this.map.SizeToFit(); this.mapContainer.SizeToFit(); this.map.SizeToFit(); this.View.Frame = new System.Drawing.RectangleF(0,0,this.View.Frame.Width, this.View.Frame.Height ); this.mapContainer.LayoutSubviews(); } catch(Exception ex) { Console.Write(ex.ToString()); } }

  • On Update: Auto Update Date/Time Field

    - by Abs
    Hello all, Is there an equivalent of MySQLs on update field for SQL server? With both DEFAULT CURRENT_TIMESTAMP and ON UPDATE CURRENT_TIMESTAMP clauses, the column has the current timestamp for its default value, and is automatically updated. What I am looking for is to have a date/time field and every time I update a record it updates the field with the date/time it was updated automatically? If it doesn't exist, I guess I'll have to go manual. Thanks all

  • Struts 2 - Accessing different properties on the ValueStack sharing the same name

    - by veggen
    Struts 2 will resolve all property names during view rendering against the top object in the ValueStack first. But how can one access a property with the same name on the object lower on the stack? Example: Let's say I have an Action class called MyAction and it has a a logDate property. In the view rendered after this action is invoked, there's this: Now imagine a User object also has a logDate property. During the iteration, Struts 2 will always push the current user object to the top of the ValueStack effectively resolving all property names against it. But, what if I wanted to access logDate from the action? What's the correct way to do this?

  • How do I branch if message.properties-code exists

    - by skurt
    I want to branch if a message-property-code does exist or not. <g:if test="${message(code: 'default.code.foo')}"> true </g:if><g:else> false </g:else> should answer true if there a message property named default.code.foo and false if not. It fails because it answers the code if there is no property for it.

  • auto-import of packages across project in eclipse

    - by Reddy
    I have used file search functionality in eclipse to replace a specific occurrence of text with a replace text which contains a java method name in all files across the workspace. But now in all those files I have to add the import statement (for the method name to resolve). Is there an automatic way of doing this instead of manually searching and importing the package myself in all files?

  • Accessing primitive properties from objects stored in a NSDictionary

    - by ChrisS
    Apologies if this is a basic question, I am just starting with Objective-C and trying to wrap things around in my head! I have a simple class of the form: @interface Whatever : NSObject { int somePrimitive; SomeObject* someObject; } @property (nonatomic) int somePrimitive; @property (nonatomic, retain) SomeObject* someObject; The class is more involved that this, but this illustrates the purpose. When I store instances of this class in a NSMutableDictionary: Whatever *whatever = [[Whatever alloc] init]; whatever.somePrimitive = 1; whatever.someObject = ...; [myDictionary setObject:whatever forKey:@"someKey"]; and then try to retrieve the object later: Whatever *result = [myDictionary valueForKey:@"someKey"]; then, result.someObject is ok to reference but, result.somePrimitive crashes. Does the NSDictionary not copy over the primitives of the object? Is the rule that the object stored in a dictionary should only contain objects?
