communication

问题 I was messing around with communicating inside a Google Chrome extension and was using the following guide: https://developer.chrome.com/extensions/messaging It used to work but I have encountered an error : Error in response to tabs.query: TypeError: Cannot read property 'id' of undefined I compared my code and the Google Chrome code and I can't seem to find why my code produces that error: chrome.tabs.query({active: true, currentWindow: true}, function(tabs) { chrome.tabs.sendMessage(tabs[1

问题 I have programmed a telegram bot. This works fine when sending to groups or to users. However I do a special requirement. I need to be able to send to another bot. When adding both bots to a group as administrators. I still cannot receive the message with my second bot. I only see it with my real user account, that is added to this group. What am I missing? I used OKHttp to send the message Request request = new Request.Builder() .url("https://api.telegram.org/bot"+telSetup.getToken()+"

问题 I have an application in Android which get latitude and longitude from GPS. I want to send these lat and long to server at particular port and want to receive the response of server into my Android application. Kindly give the direction so that I can make it possible. 回答1: There are many ways to perform this data transfer using the Android platform. My preference is to use JSON to communicate between the App and the server. For an example of how to implement this in your app read through this

问题 I have a really simple Java class that effectively decorates a Map with input validation, with the obvious void set() and String get() methods. I'd like to be able to effectively call those methods and handle return values and exceptions from outside the JVM, but still on the same machine Update: the caller I have in mind is not another JVM; thanks @Dave Ray My implementation considerations are typical performance ease of implementation and maintenance (simplicity?) reliability flexibility (i

问题 All. Firstly I am aware of the question Send data back to .exe from dll, however the answers there leave too many open ends for me and as I have no experience of what I am attempting I feel a new question is warranted. I have an existing C# [ All WinForms here ] app that heavily relies on SQL. We have been asked (by clients) to provide an SQL Editor and library that can be used to develop and test SQL, but that can also be used to paste directly back in to the main application. The new

问题 I'm working on a project where I'll have one application in C# and another one in Python. The C# application will continuously analyse stream of data and raise a flag each time something interesting is detected. So each time there will be an event, my Python application will have to read it and continues with it own process, while other flags will continue being sent. As you understand the C# app won't wait for the Python one to finish its computation before sending another flag. So I was

问题 I have read a lot of questions regarding this subject on this website however they didn't quiet answer my question. If you can't be ### about my goal or background skip to the question. My Goal Is to build a server that can run on Mac OS X 10.4+ and later, port it to Windows XP/Vista (no idea how to do that yet, but that's a problem for later). Then let the iPhone be the client that is able to see the computer names that are running the server (through WiFi). The user of the iPhone can then
