问题 To help reduce dependencies between my ViewModels, I am trying to create my own Messenger service. Here is some code: public struct Subscription { public Type Type { get; set; } public string Message { get; set; } //Error: Cannot implicitly convert type 'System.Action<TPayload>' to 'System.Action' public Action Callback { get; set; } } public static class Messenger { private static List<Subscription> Subscribers { get; set; } static Messenger() { Subscribers = new List<Subscription>(); }

问题 I am getting started with workflows in ServiceNow. I can see that the trigger for at workflow is based on conditions. But can a workflow be triggered by some sort of user action, i.e. a UI Action/button or through a script? 回答1: There's a Workflow object accessible server side that you can use to start a workflow that's documented here. Here's an example from that wiki article: // where current is a task record with a workflow context var w = new Workflow(); var context = w.startFlow(id,

问题 I have some code that has got me very close to what Im trying to achieve. But there are a few issues. What I want to do is, when a Button is pressed and held, it will continuously call a method AdvanceLog(). The problem is, the ACTION_DOWN motion event does not continue to get called. What happens is, when you press and hold, the first motion is ACTION_DOWN and every motion thereafter while still holding down is ACTION_MOVE. This is causing some issues, as I am not REALLY looking for the move

问题 I'm trying to create an android notification with action buttons. I have already set one up which starts an activity, but I would like another which dismisses the notification and doesn't take the user to another screen/Activity (not taken to any part of my app) I don't want to use '.auto cancel(true) ' because I want the notification to be kept unless this action button is pressed. The primary use would be for ongoing notifications as they cannot be removed with a swipe. The idea is similar

问题 I have method in my controller: def work_here @company = Company.find(params[:id]) current_user.work_apply(current_user, @company) redirect_to company_path end On my view: <%= render 'companies/work_form' if signed_in? %> _work_form.html.erb: <%= form_for company, :remote => true, :url => { :controller => "companies", :action => "work_here" } do |f| %> <%= f.hidden_field :id, :value => company.id %> <%= f.submit "I working here" %> <% end %> And I have a work_here.js.erb file: $("#work_at

问题 I was wondering why when you create restful routes in rails with map.resources it generates actions for new, create, edit, update ? Is there anything wrong in declaring just one action for create and update and do something like this? def create unless post? @user = User.new else redirect_to :action => 'index' if user.create(params[:user]) end end so we could have something like :GET users/create # to show the form (same as action - new) :POST users/create # to create a new user since Restful

问题 I have a list of methods that do pretty much the same thing, except a few differences: void DoWork(string parameter1, string parameter2) { //Common code ... //Custom code ... //Common code ... } I want to streamline the solution with reusing the common code by passing custom code from another method. I assume I have to use an action with parameters to accomplish this, but can't figure out how. 回答1: The other answers are great, but you may need to return something from the custom code, so you
