communication

I am creating a WatchKit app and was wondering how to send a message/data from the iPhone to the Watch? I know how to do it the other way around (watch -> phone) using ' openParentApplication:reply: ' and ' application:handleWatchKitExtensionRequest:reply: ' but can't find any documentation on how to communicate from phone to watch. Simple setup would be the iPhone app has a button that when pressed should update a label on the Watch app. Can anyone point me in the right direction? First, you have to enable app groups for your target: Then you can start to write and read objects via

I'm trying to call a HTTP JSON-RPC server for Bitcoin using Go (not on GAE), but I get error of dial tcp http://user:pass@127.0.0.1:8332: too many colons in address or dial ip http://user:pass@127.0.0.1:8332: lookup http://user:pass@127.0.0.1:8332: no such host I tried various network configurations , but couldn't get anything going. When I just typed the address into the browser, I got a response from the server: {"result":null,"error":{"code":-32700,"message":"Parse error"},"id":null} Which looks like a proper response for an empty call. How do I correctly call that HTTP JSON-RPC server in

Is it possible to find foreign instances of certain website? Ofc theese are independently opened tabs (not by window.open). I need to prevent user from opening 2 tabs, and send message to previously opened tab to inform that it's impossible to open 2 tabs. 2 Intependent tabs may break page offline storage and webSQL structure, so that I can't allow people to use 2 tabs. It's also semi-offline app so it needs to be client-side solution. You can communicate across tabs using localStorage. Every time you write a value, a "storage" event is fired on the window object on every tab (except the

In C#, using winforms, what is the best way to make forms talk to each other? Sending data, messages, strings, whatever, from on to the other? Delegates? Ideas? We'ved used something called the Event Pattern successfully in several Winform applications. Here's a good link that will help you get started. You can create events in one form and then register for those events in the other form. You can also simply access properties from one form to the other. For example maybe in the constructor of the second form, you would pass a variable for the first form. It sounds like what you're looking for

I'm making an application in Python3, which will be divided in batch and gui parts. Batch is responsible for processing logic and gui is responsible for displaying it. Which inter-process communication (IPC) framework should I use with the following requirements: The GUI can be run on other device than batch (GUI can be run on the same device, on smartphone, tablet etc, locally or over network). The batch (Python3 IPc library) should work with no problem on Linux, Mac, Windows, ... The IPC should support GUI written in different languages (Python, Javascript, ...) The performance of IPC is
