Using inputStream and OutputStream to read and write data to a process

I am currently running a .class file as a process. The .class file is a simple program that asks the user to input a number, takes the input and prints the user's input back to the screen. Up to now, i have managed to print the "Enter a number: " statement from the process on the console through InputStream and write the input entered by the user through OutputStream. I am unable to print the last statements on the screen, which should be "You entered : " + userinput My code is: String command [] = {"java" , "-cp", "C:\\Users\\Mahika\\Documents\\NetBeansProjects\\JavaTest\\compilerTest",

How to get query string from JavaScript Object without jQuery?

I'm looking for an dependency-free implementation of jQuery.param(). I'm trying to create a serialized representation of an array or object, suitable for use in a URL query string or Ajax request, without using jQuery. I searched for some time now, but everyone just seems to use $.param()... Thank you in advance!

Calling C printf from assembly

I would like to call the printf function from C with two integers. My format string is: LC0: db "odd bits: %d, even bits: %d", 10, 0 I have the integer ob and eb: ob: DD 0 eb: DD 0 and then I do at the end: push dword [ob] push dword [eb] push LC0 call printf add esp,8 However, this gives me the result Odd bits: [ob], Even bits: [ob, repeated] then gives me a segmentation fault. Am I calling the printf function wrong? EDIT: I added LC1 as db "even bits: %d", 10 0, then redid: push dword [ob] push LC0 call printf push dword [eb] push LC1 call printf add esp, 8 This gives me a REVERSED result

Does SignalR or websockets works with ASP.NET CORE 1.0?

I need to implement realtime data sharing push based to my asp.net core 1.0 web application. i.e. If any new data is available I want to push it to all the connected clients/logged in users. I was considering SignalR & websockets for it but SignalR works on .net core 2.0 and websockets works on .net core 1.1 version. Here is the configuration in my csproj file <PropertyGroup> <TargetFramework>netcoreapp1.0</TargetFramework> <RuntimeFrameworkVersion>1.0.4</RuntimeFrameworkVersion> <PackageTargetFallback>$(PackageTargetFallback);dotnet5.6;portable-net45+win8</PackageTargetFallback> <
