Asking for modifications like this is pointless, the Windows Forms team has been disbanded quite a while ago. It is in maintenance mode, only security issues and OS incompatibilities are considered. It is otherwise simple enough to create your own method to do this: public static class ExtensionMethods { public static void Clear(this Control.ControlCollection controls, … Read more
Beside the solutions using the @Input/@Output and a parent component as a ‘bridge’, a common way would also be introducing a shared service. The service needs to be provided in a parent component so the children can share single instance of the service (How do I create a singleton service in Angular 2?). Basic example … Read more
Component approach I would suggest you to align with Angular 2 component approach and use inputs/outputs approach. If you do so, you will be able to easily migrate to Angular 2, because components will be conceptually identical (with difference only in syntax). So here is the way you do it. So we basically want header … Read more
Updated: 19/03/2017 this.form.controls[‘dept’].setValue(selected.id); OLD: For now we are forced to do a type cast: (<Control>this.form.controls[‘dept’]).updateValue(selected.id) Not very elegant I agree. Hope this gets improved in future versions.
what benefits does OSGi’s component system provide you? Well, Here is quite a list: Reduced Complexity – Developing with OSGi technology means developing bundles: the OSGi components. Bundles are modules. They hide their internals from other bundles and communicate through well defined services. Hiding internals means more freedom to change later. This not only reduces … Read more
You could leverage a ReplaySubject for that: EDIT: Different since RxJS 6.x: Note the use of the pipe() method. class myComponent { private destroyed$: ReplaySubject<boolean> = new ReplaySubject(1); constructor( private serviceA: ServiceA, private serviceB: ServiceB, private serviceC: ServiceC) {} ngOnInit() { this.serviceA .pipe(takeUntil(this.destroyed$)) .subscribe(…); this.serviceB .pipe(takeUntil(this.destroyed$)) .subscribe(…); this.serviceC .pipe(takeUntil(this.destroyed$)) .subscribe(…); } ngOnDestroy() { this.destroyed$.next(true); this.destroyed$.complete(); … Read more
For each sort graph you need some kind of model, which should hold the current state of each sort. This would probably mean adding your list of ints to a separate list per sort. You would also need some kind of mechanism that would allow you to loop through each sort algorithm and tell it … Read more
update forwardRef() isn’t required anymore because directives was moved to NgModule.declarations and therefore recursive components don’t need to be registered on themselves as directives anymore. Angular 4.x.x Plunker example original That supported. You just need to add the component to directives: [] in its @Component() decorator. Because the decorator comes before the class and classes … Read more
Update for 10.4 Delphi 10.4 Sydney unified memory management across all platforms and removed ARC compiler. In other words, all platforms now follow the same memory management rules as the Windows platform. DisposeOf vs Free in classic (non ARC) compiler DisposeOf on classic compiler calls Free and functionally behaves the same DisposeOf is left for … Read more
If you are providing your DataService inside the providers array of your @Component annotation, @Component({ … providers: [DataService], })… this service will be a singleton (it will create a new instance) for this component (and it’s children if they have not provided this service under their annotation also). If you want to use this service … Read more
