问题 I have an application that must read it's own output that is written via Console.WriteLine("blah blah"); I'm trying Process p = Process.GetCurrentProcess(); StreamReader input = p.StandardOutput; input.ReadLine(); But it doesn't work because of "InvalidOperationException" at the second line.

And to be complete how to

问题 I've added some methods to an existing project. It was writing correctly to a txt file. However i can only see my recently added std::cerr texts now, i execute my project like ./faceDemo > run.txt What are the possible reasons? 回答1: If you wish to redirect the error flow, you should use something like that : ./faceDemo > std.log 2> err.log And if you wish to redirect both flows in the same file use this : ./faceDemo > run.txt 2>&1 2>&1 means redirect error flow into std flow 来源： https:/

How do I print from a Python 2.7 script invoked from Bash within PyCharm?

阅读更多关于 How do I print from a Python 2.7 script invoked from Bash within PyCharm?

问题 For example if I have a python script test.py containing import time print 'foo' time.sleep(5) print 'bar' time.sleep(5) and a shell script run_test.sh containing #!/usr/bin/env bash python test.py then running the latter (using the Run menu item for example) from within PyCharm (2016.1) prints no output until the entire script has completed (after about 10 seconds). Is there a way to print output as my shell script runs? 回答1: Looks like you need to explicitly flush the buffer: import sys

问题 @Override public void actionPerformed(ActionEvent e) { if (e.getSource() == thirdBtn) { //System.out.println("Third Button Click"); System.out.println(e.getSource()+" Click"); } } In the code above, I was wondering if instead of doing this: //System.out.println("Third Button Click"); if I could do something like this: System.out.println(e.getSource()+" Click"); However the code outputs: BlackJack.OverBoard$BlackJackButton[,440,395,100x25,alignmentX=0.0,alignmentY=0.5, border=javax.swing.plaf

问题 Currently I've successfully write to my file some random numbers between 0 to 10 with this code(below is just some sample code to demonstrate the problem): for (int i = 1; i <= size; i++) { type = rand () % 3; switch (type) { case 0: afile << rand () % 10; break; case 1: afile << rand () % 10; afile << "\t\t"; afile << rand () % 10; break; case 2: afile << rand () % 10; afile << "\t\t"; afile << rand () % 10; afile << "\t\t"; afile << rand () % 10; /*afile << "8"; afile << "\t"; afile << "7";

cmp command returning EOF on my output despite exact match as far as i can tell

阅读更多关于 cmp command returning EOF on my output despite exact match as far as i can tell

问题 So I will start by saying this is for a course and I assume the professor won't really care that they are the same if cmp returns something weird. I am attempting to compare the output of my code, named uout, to the correct output, in the file correct0. The problem however is that it returns "cmp: EOF on uout". From a little bit of digging I found that EOF indicates they are the same up to the end of the shorter file with the shorter file being the one named after EOF, so what I gather from

PHP输出缓冲控制

阅读更多关于 PHP输出缓冲控制

简介说到输出缓冲，首先要说的是一个叫做缓冲器(buffer)的东西。举个简单的例子说明他的作用：我们在编辑一篇文档时，在我们没有保存之前，系统是不会向磁盘写入的，而是写到buffer中，当buffer写满或者执行了保存操作，才会将数据写入磁盘。对于PHP来说，每一次像 echo 这样的输出操作，同样是先写入到了 php buffer 里，在脚本执行完毕或者执行了强制输出缓存操作，数据才会在浏览器上显示。其实对于PHP程序员来说，基本上每个脚本都涉及到了输出缓冲，只是在大多数情况下，我们都不需要对输出缓冲进行更改。而今天就来用实例对PHP输出缓冲控制函数“Output Control”做一个详细的解析。下面这个例子简单介绍了输出缓冲在一般脚本中存在的方式：我们在执行如下脚本时： <?php /*例1*/ echo 'oschina.net'; echo '红薯'; echo '虫虫'; ?> 脚本在执行完第一个 echo 时，并不会向浏览器输出相应内容，而是会输出到一个缓冲区，依次类推，当三个 echo 全部执行完毕(也就是脚本结束)时，才会将缓冲区内容全部输出到浏览器。当然这个缓冲区也有大小的限制，是根据 php.ini 中的 output_buffering 选项来设置的，这点会在下面的文章中详细介绍。而本章所讲的输出缓冲控制，就是在脚本结束前，对缓冲区里的内容进行操作。

JavaFX specific Audio Output

问题 I have a little problem with JavaFX and the Java Sound API. I want to use 2 outputs of the computer at the same time (USB-Headset and normal boxes). Its no problem to get all the outputs with the java sound api, but the java sound api doesn't support MP3 files. Is it possible to configure the output in JavaFX? Is there another solution for this problem? 来源： https://stackoverflow.com/questions/16911579/javafx-specific-audio-output
