runtime

问题 I want to start a process with Runtime.exec() . Then I want to know (listen) when the process exits. Also, I want to manually stop the process if some condition met. The code I have now is: public class ProcessManager extends Thread{ private static ProcessManager manager; Process process; private ProcessManager(){ } public static ProcessManager getInstance(){ if(manager==null){ manager=new ProcessManager(); } return manager; } public void run(){ Runtime runtime = Runtime.getRuntime(); process

问题 In the following PHP code I would like to replace the __CLASS__ magic constant in the Foo class with a function __X__() (or something similar) so that when the method hello() is called from an instance $bar of the Bar class, it prints hello from Bar (instead of hello from Foo ). And I want to do this without overriding hello() inside Bar . So basically, I want a version of __CLASS__ that binds dynamically at run-time rather than at compile-time. class Foo { public function hello() { echo

问题 In my project I have an doSomething.m and soSomething.h files with the only C function: void doSomething() { } The first question : what should I do to make this function accessible from any place in my code without needing to import any headers? Note: I guess that to solve this problem the doSomething.h file is not needed at all, but its presence/absence is not a restriction. I have the following pieces of knowledge but I can't have the whole picture of what is needed: I can use some another

问题 I would like to load module in asp.net mvc dynamically after the runtime is realized. So I follow many tutorials and different ways to do it. Finally I found the solution from http://www.squarewidget.com/pluggable-architecture-in-asp.net-mvc-4. I follow the code described and I try to load the assembly later. I use the class NInjectWebCommon.cs All lib have been loaded from the bin path project. I add the plugin.dll : it's the module and when I try to browse the index page from the module it

问题 This is a program to read a file and print out the file with some of the text edited. The code will compile the issue is that it will read the users input but will say file is not found when the file is there. I feel like I am missing something. I am brand new at this so go easy on me. 回答1: import java.io.File; import java.io.FileNotFoundException; import java.util.Scanner; public class MainTest { public static void main(String args[]) { // if (args[0] != null) readFile(); } public static

问题 Im building an GUI that will help my team mates to execute some jars without going using the terminal (with all the validating and stuff). At some stage, the gui sould gather params from the gui and execute them, something like : --start -Xbootclasspath/p:lib/OB-4.3.4.jar:lib/OBNaming-4.3.4.jar -Dmy.property.ns=corbaloc:iiop:localhost:900/NameService -Dmachine=energie -Dexecutable=MOREventd -DtypeArbo=1 -jar MOREventd I was wondering how could i do that since Runtime Exec doesn't work with

问题 my method is : private void button1_Click(object sender, EventArgs e) { for (int i = 1; i < 10; i++) { Button btn = new Button(); btn.Name = "btn" + i.ToString(); btn.Text = "btn" + i.ToString(); btn.Click += new EventHandler(this.btn_Click); this.flowLayoutPanel1.Controls.Add(btn); } } void btn_Click(object sender, EventArgs e) { Button btn = (Button)sender; if (btn.Name == "btn1") { this.Text = "stack"; } } There is a better approach ? 回答1: The code you used: btn.Click += new EventHandler

问题 It's easy to load functions from dynamic libraries when you know this function in design time. just do something like this: int (*fn)(int); l0 = dlopen("./libfoo.so", RTLD_LAZY); if (!l0) { fprintf(stderr, "l0 %s\n", dlerror()); return 1; } fn = (int (*)(int))dlsym(l0, "foo"); if ((error = dlerror()) != NULL) { fprintf(stderr, "fn:%s\n", error); return 1; } x=(*fn)(y); ... How to execute library function when it's unknown in design time? In runtime you have a function name and array of
