Is it possible to send an information/update about availability Stock Item to e.g. Amazon using Push Notification. Have any of you tried something similar?
In theory, you should be able to do it with an IPushNotificationSender implementation. Using this you should be able to get any custom logic you need to directly engage whatever endpoint you need.

Let's say I have a notes app. I want to enable the user to make changes while he is offline, save the changes optimistically in a Mobx store, and add a request to save the changes (on the server) to a queue.
Then when the internet connection is re-established I want to run the requests in the queue one by one so the data in the app syncs with data on the server.
Any suggestions would help.
I tried using react-native-job-queue but it doesn't seem to work.
I also considered react-native-queue but the library seems to be abandoned.
You could create a separate store (or an array in AsyncStorage) for pending operations, and add the operations to an array there when the network is disconnected. Tell your existing stores to look there for data, so you can render it optimistically. Then, when you detect a connection, run the updates in array order, and clear the array when done.
You could also use your existing stores, and add something like pending: true to values that haven't posted to your backend. However, you'll have less control over the order of operations, which sounds like it is important.
As it turns out I was in the wrong. The react-native-job-queue library does work, I just made a mistake by trying to pass a function reference (API call) to the Worker instead of just passing an object that contains the request URL and method and then just implement the Worker to make the API call based on those parameters.
I really like the Parse push service and integrated it with our CMS. I would like to make the notifications personal by adding the users name in the push message. How can i use a variable (Named 'voornaam' in the screenshot) which is stored in the Installation class in a push message?
If you are looking for something like a message template like
Hello ${username}, what's up
sadly its not there. One way you can make the kind of message you want to is by doing it in your server side code before you send the request for PUSH using the REST or other APIs
Can I extend the server-side Java Code in Worklight?
For example, there is a class called JavaScriptIntegrationLibraryImplementation under com.worklight.integration.js. Inside this class, there is a method broadcastNotification and I would like to override this method. Is it possible to do so?
EDIT
The reason is that:
When I make the subscription in client side with option field (e.g. add customType: A), I would like to retrieve a list of devices which have been subscribed to this event source. Base on the option field in deviceSubscrpition, I would like to have some business logic to determine who to send the notification message. For example, I will only submit the message to the user which 'customType=A'.
However, there is no API in Worklight which can retrieve a list of devices which make me to retrieve the list first. Then do the logic in JavaScript and called WL.Server.notifyDevice..
Therefore, I would like to check whether there is any method to retrieve a list of devices (through API / Adapter which connects to DB) which have subscribed to an event source.
Thanks.
This part of Worklight is not extendable. You can try and override this method as you say, but do note this is not supported and we cannot help in this case.
Edit
Now that it is clear what you're trying to achieve... what you are looking for currently not available. I will open a feature request for it and it will get evaluated at some point (if you are a customer of IBM, I suggest to get in touch with your contact...).
My suggestion (somewhat hackish in form): you could perhaps use multiple Event Sources, where each event source represents an iOS version. On the client-side, upon app initialization, you can retrieve the iOS version and use it to register to the correct event source (this would be very generic code to allow re-use). In case a new iOS version is released (you will likely know of this in advance), you simply add this event source to the adapter code and re-deploy the adapter. Users of the new iOS version could still register for notification, because you get the iOS version upon init, and use this information to register to the correct event source...
To reiterate:
The adapter contains: ES_iOS5 ES_iOS6
The client:
fetches iOS version, stores it in some variable.
registers to event source, where event source name is ES_${iOSVersion}
if a new iOS version is released, simply create a new event source and re-deploy
the adapter; the client is already equipped to handle this.
#Red23jordon,
i had similar case, i created a custom table where at the time of subscription, I was saving
user ID and event type in custom table. and when user unsubscribe then i also remove details from custom table.
For sending push to users subscribed to a particular "even type" i look into custom table to get list of user IDs subscribed to particular event type, and then i went into Notification user/device tables and fetching corresponding devices and sending Push.
Hope it may help you.
thanks
I've spend days trying to find a solution the problem i'm going to try to describe, i've googled alot and even looked at the .NET 4 reference source for SendReply and InternalSendReply activity. But until now i'm stuck.
To make the life of our end customers simpler i want to replace the Receive and SendReply activities with custom activites and use bookmarks instead.
I'm implementing a central webservice which can route to a correct workflow instance, that workflow modifies the bookmark value and finaly it creates a new bookmark while returning the modified bookmark value. It's rather complex already with a WorkflowServiceHostFactory which adds Behaviours and Attach a DataContractResolver to the endpoint.
The endpoint is derived from WorkflowHostingEndpoint which resolves a bookmark created in a custom activity (instead of a receive). And i want another activity instead of a sendreply. Those 2 should correlate and the custom sendreply does send a response on the open channel through the endpoint while creating a new bookmark.
The problem is that i didn't find a way yet to access the endpoint responseContext from within my custom send activity. On the other side, at the workflowcreating endpoint side, it seems that i'm not able to be notified whenever the workflow becomes Idle and as well i don't seem to be able to access the WorkflowExtensions from the host. i'm missing something?
A possible solution i've in mind might be not using a WorkflowServiceHost, but then i loose alot of AppFabric functionaly.
The workflowapplication in platform update 1 has some extension methods called RunEpisode with an overload Func called idleEventCallback. There it's possible to hook into the OnIdle and get a workflowextension to get the object to send back as response.
To answer my own question, i ended up in a workaround using the servicebroker functionality of sql server. The SqlDependency class where the workflow listens for the event to be fired whenever the workflow reach the activity that creates a new bookmark in another state.
I'm working on a small application using C++/wxWidgets, where several parts of the GUI need to be updated based on e.g. received UDP datagrams. More specifically, a secondary thread tries to keep a list of available "clients" in the network (which may come and go away) and e.g. corresponding comboboxes in the UI need to be updated to reflect the changes.
The documentation mentions that for this kind of thing EVT_UPDATE_UI would be a good choice. As far as I can understand from the sparse documentation, this event is sent automatically by the system and provides some support for assisted UI change.
However, I'd feel more comfortable using a more direct approach, i.e. where e.g. a window object could register/subscribe to receive notifications (either events or callbacks) upon particular events and another part of the code is sending out these notifications when required. I could do this in C++ using my own code, however I guess if wxWidgets already supports something like that, I should make use of it. However I haven't found anything in that regards.
So, the question is: does wxWidgets support this kind of notification system (or similar alternatives) or would I be best served coding my own?
AFAIK there is nothing directly usable in wxWidgets, but doing it on your own seems easy.
What I would do:
Create a wxEvtHandler-descendent class to hold the list of available "clients" in the network. Let this class have a wxCriticalSection, and use a wxCriticalSectionLocker for that in all methods that add or delete "clients".
Create a worker thread class by inheriting wxThread to handle your UDP datagrams, using blocking calls. The thread should directly call methods of the client list object whenever a client has to be added or removed. In these methods update the list of clients, and ::wxPostEvent() an event to itself (this will execute the whole notification calls in the main GUI thread).
Handle the event in the client list class, and notify all listeners that the list of clients has changed. The observer pattern seems to me a good fit. You could either call a method of all registered listeners directly, or send a wxCommandEvent to them.
Have you tried calling Update() on the widget(s) that change? Once you update the contents of the combo box, call Update(), and the contents should update.
