Calling a java program from another

拜拜、爱过 提交于 2019-12-06 20:41:32
How do i call a Java command from a stand alone java program. I understand that Runtime.getRuntime().exec("cmd c/ javac <>.java"); would work. However, this would be platform specific. Any other APIs available that could make it work in j2sdk1.4 ? If you can run everything in the same JVM, you could do something like this: public class Launcher { ... public static void main(String[] args) throws Exception { launch(Class.forName(args[0]), programArgs(args, 1)); } protected static void launch(Class program, String[] args) throws Exception { Method main = program.getMethod("main", new Class[]

Streaming commands output progress from Goroutine

一世执手 提交于 2019-12-06 15:02:42
问题 Streaming commands output progress question addresses the problem of printing progress of a long running command. I tried to put the printing code within a goroutine but the scanner claims to have already hit the EOF immediately and the for block is never executed. The bufio.scan code that gets executed on the first execution of the Scan() method is: // We cannot generate a token with what we are holding. // If we've already hit EOF or an I/O error, we are done. if s.err != nil { // Shut it

Does “setTimeout(functon(){//do stuff},0)” cause a minuscule execution delay for it's contained function?

I set up an simple experiment out of curiosity: I dynamically generated a div with the class box before attaching a click listener to it with JQuery. I then created a duplicate of this, except this time, I added a timeout of zero before the box element is generated. As shown in the JSFiddle , using a timeout of zero results in the failure of the click's intended result event to be triggered. This script results in an alert on click. $(document).ready(function(){ //setTimeout(function(){ $(".wrapper").html('<div class="box"></div>'); //},0) $(".box").click(function(){ console.log("A box was

Is it possible to run openoffice macro from external file?

问题 I want to run OpenOffice macro from external file. Like: vlad@leo ~ $ soffice macro:///home/vlad/q.vbs 回答1: Not really an answer - just a comment instead, so as to bump this question, and hopefully get an answer :) This possibly has to do with having to explicitly set permissions for macros, for instance: Can't execute macro from command line (View topic) • OpenOffice.org Community Forum Edit: In fact it seems to be impossible to call document macros, which is perfect for security reasons.

Execute a shell command from a .NET application

流过昼夜 提交于 2019-12-06 03:11:11
问题 I need to execute a shell command from my .NET application, not unlike os.execute (a little way down on that page) in Lua. However with a cursory search I couldn't find anything. How do I do it? 回答1: System.Diagnostics.Process p = new System.Diagnostics.Process(); p.StartInfo.FileName = "blah.lua arg1 arg2 arg3"; p.StartInfo.UseShellExecute = true; p.Start(); Another way would be to use P/Invoke and use ShellExecute directly: [DllImport("shell32.dll")] static extern IntPtr ShellExecute(

Python sending command over a socket

帅比萌擦擦* 提交于 2019-12-06 02:54:35
问题 I'm having a bit of trouble. I want to create a simple program that connects to the server and executes a command using subprocess then returns the result to the client. It's simple but I can't get it to work. Right now this is what I have: client: import sys, socket, subprocess conn = socket.socket(socket.AF_INET, socket.SOCK_STREAM) host = sys.argv[1] port = int(sys.argv[2]) socksize = 1024 conn.connect((host, port)) while True: shell = raw_input("$ ") conn.send(shell) data = conn.recv

Python C API - Stopping Execution (and continuing it later)

一笑奈何 提交于 2019-12-06 02:07:14
1) I would like to use the profiling functions in the Python C API to catch the python interpreter when it returns from specific functions. 2) I would like to pause the python interpreter, send execution back to the function that called the interpreter in my C++ program, and finally return execution to the python interpreter, starting it on the line of code after where it stopped. I would like to maintain both globals and locals between the times where execution belongs to python. Part 1 I've finished. Part 2 is my question. I don't know what to save so I can return to execution, or how to

relationship between VMA and ELF segments

谁都会走 提交于 2019-12-06 02:01:05
I need to determine the VMAs for loadable segments of ELF executables. VMAs can be printed from /proc/pid/maps . The relationship between VMAs shown by maps with loadable segments is also clear to me. Each segment consists of one or more VMAs. what is the method used by kernel to form VMAs from ELF segments: whteher it takes into consideration only permissions/flags or something else is also required? As per my understanding, a segment with flags Read, Execute (code) will go in separate VMA having same permission. While next segment with permissions Read, Write(data) should go in an other VMA.

Prevent JavaScript function from running twice (setTimeout)

This function is ran when a button is clicked. function complete() { var div = document.getElementById('log'); setTimeout(function(){ div.innerHTML = div.innerHTML + intro[Math.floor(Math.random() * intro.length)] + "<br>"; }, 500); setTimeout(function(){ div.innerHTML = div.innerHTML + second[Math.floor(Math.random() * second.length)] + "<br>"; }, 2560); setTimeout(function(){ div.innerHTML = div.innerHTML + third[Math.floor(Math.random() * third.length)] + "<br>"; }, 4860); setTimeout(function(){ div.innerHTML =

Stopping all javascript execution

Is there an equivalent to the php die() function for javascript that stops all javascript (including future callbacks for ajax requests, timeouts etc...) from running? (NOTE: I can't use breakpoints in the debugger as the bug is in ie8 and the debugger prevents you from scrolling up/down the page while at a breakpoint; to be able to see at which point the bug is occurring I need to be able to scroll the page while the code is stopped) Is there an equivalent to the php die() function for javascript that stops all javascript (including future callbacks for ajax requests, timeouts etc...) from
