stdout

问题 I run a DOS command from a python environment which retrieves its command output via stdout. All is working fine excepted that the windows console pops out everytime the script runs, so I need a way to hide the windows console. Schematically, here is the expected process: "Console1" runs "hidden Console2" and retrieves its output into "Console1" I read some recommendations with softwares like " HiddenStart " or " chp " which hide the console when executing DOS commands and batch scripts.

问题 I'm building a PromptSet that can ask a series of questions in a row. For testing reasons, it allows you to pass a reader and writer instead of using stdin & stdout directly. Because stdin and stdout are the common use case, I would like to create a default "constructor" that allows the user to produce a PromptSet<StdinLock, StdoutLock> without needing any parameters. Here's the code so far: use std::io::{self, BufRead, StdinLock, StdoutLock, Write}; pub struct PromptSet<R, W> where R:

问题 #include <iostream> #include <fstream> using namespace std; void foo(){ streambuf *psbuf; ofstream filestr; filestr.open ("test.txt"); psbuf = filestr.rdbuf(); cout.rdbuf(psbuf); } int main () { foo(); cout << "This is written to the file"; return 0; } Does cout write to the given file? If not, is there a way to do it without sending the variables to foo, like new ? update : I can't use a solution that uses class or uses global so plz can some give me solution that use new. Also passing the

问题 For a standard Python Console window, you can remove the last line with for example sys.stdout.write('\r'+' '*len(line)) as I explained here. But for editors like SciTe, Idle or Eclipse (with PyDev), the stdout is a file-type object, probably flushing its content to the console window leaving its buffer empty and thus not allowing modify the content once it has appeared on in the window. What trick can be applied to, for example, erase the last line of such console? Is there a one-size-fits

问题 What's the easiest way to execute a process, wait for it to finish, and then return its standard output as a string? Kinda like backtics in Perl. Not looking for a cross platform thing. I just need the quickest solution for VC++. Any ideas? 回答1: WinAPI solution: You have to create process (see CreateProcess) with redirected input (hStdInput field in STARTUPINFO structure) and output (hStdOutput) to your pipes (see CreatePipe), and then just read from the pipe (see ReadFile). 回答2: hmm.. MSDN

问题 I'm trying to do a system of notifications automatic (Iphone) using https://github.com/simonwhitaker/PyAPNs. When you want to send a notification you call "apns.gateway_server.send_notification(key, payload)" and you have to enter the PEM pass phrase. Is there a way to enter this phrase through code? Something like: call(apns.gateway_server.send_notification(key, payload), sys.stdout.write("my phars")) I don't know how to do it 回答1: import apns gate = apns.APNs('keyfile','certfile').gateway

问题 there are a lot of examples that show how to redirect the stdout of another application. However I would like to let the application keep its stdout and only retrieve a copy of the stdout in my parent process. Is this possible? My scenario: I have some tests (using Visual Studio Test Runner) which start an external process (server) to do their testing. The server outputs a lot of useful debug information in its stdout which I would like to include in my test results. I can capture the process

问题 I use nodejs to captured its child process's stdout data, but always captured the former part of child process's stdout data. When I add fllush(stdout) ，It works OK. But I don't know why, and don't want to add flush(stdout). Here is my code: var tail_child = spawn(exefile, [arg1, arg2, arg3]); tail_child.stdin.write('msg\n'); tail_child.stdout.on('data', function(data) { console.log(data); }); child_process.c printf("data\n"); Need your help! Thank you very much! 回答1: By default, stdout in

问题 I'm having the following problem. I want to write a program in Fortran90 which I want to be able to call like this: ./program.x < main.in > main.out Additionally to "main.out" (whose name I can set when calling the program), secondary outputs have to be written and I wanted them to have a similar name to either "main.in" or "main.out" (they are not actually called "main"); however, when I use: INQUIRE(UNIT=5,NAME=sInputName) The content of sInputName becomes "Stdin" instead of the name of the

问题 I'm looking to use a personal RSS Feed for system reporting, so I'm wondering if it's possible to create a script that sends its $1 to an RSS feed, ala self_test_command > rss_report.sh . I don't currently have an RSS feed set up, either, so what would be the easiest way to set up an RSS feed running from a Linux box? 回答1: I have a proper solution for you, in command line . That use Perl Template::Toolkit module in background (no need to learn Perl just now) : first install the package perl
