Disable Recieving Buffer in Firefox (or other browsers)

阅读更多关于 Disable Recieving Buffer in Firefox (or other browsers)

问题 I got trouble with web browsers buffering (not chaching). I call this php script : sleep(5); echo '1st step'; echo (str_repeat(' ',256)); sleep(5); echo '<br />'; echo '2nd step'; output buffer is disabled on php (we will confirm that later) when calling this script with both Chromium 12 and Firefox 5 I got this result : the 'waiting' animated circle (the grey one) runs during ~5sec then the 'transferring' animated circle (the orange one) runs during ~5sec and finally i have the whole result

C - User input getting skipped?

阅读更多关于 C - User input getting skipped?

问题 I want a menu from which you choose some action. Problem is that when we choose one, and press the "return" key, the user input command which should have been the next step, is skipped. Why is that ? The code is : #include <stdio.h> #include <string.h> int main(int argc, char *argv[]) { int choice; do { printf("Menu\n\n"); printf("1. Do this\n"); printf("2. Do that\n"); printf("3. Leave\n"); scanf("%d",&choice); switch (choice) { case 1: do_this(); break; case 2: // do_that(); break; } }

Need Python 3.4 version of print() from future

阅读更多关于 Need Python 3.4 version of print() from __future__

问题 Currently, when I from __future__ import print_function from Python 2.7.6, I apparently get a version of print() prior to the addition of the flush keyword argument, which went in Python 3.3 according to the docs. The Python3 installed in my system (Ubuntu) is Python 3.4, and I verified its print() function has the flush argument. How do I import the print() function from 3.4? From where is __future__ getting the older print function? 回答1: You cannot get the version from 3.4 imported into

Is there a way to flush the DNS cache from a C# WPF app? (on XP, Vista, Win7)

问题 Is there a way to flush the DNS cache from a C# WPF app? The application would be running on either XP, Vista, or Windows 7. 回答1: This may be the poor-man's solution, but you could use System.Diagnostics.Process to launch ipconfig /flushdns . 回答2: You can use a function from Microsoft's "dnsapi.dll". This will allow you to do this completely programmatically: using System.Runtime.InteropServices; [DllImport("dnsapi.dll",EntryPoint="DnsFlushResolverCache")] private static extern UInt32

Why doesn't python3's print statement flush output when end keyword is specified?

阅读更多关于 Why doesn't python3's print statement flush output when end keyword is specified?

问题 from sys import argv, stdout as cout from time import sleep as sl print("Rewinding.......",end = '') # If end is given output isn't flushed. But why? cout.flush() for i in range(0,20): sl(0.2) print(".",end='',flush = True) #No output is printed if flush wasn't specified as true. print("Done") #Output is by default flushed here When I specified end and sleep, I noticed that output wasn't flushed until next print where it was by default flushed. Why does this happen? I had to manually flush

Not buffered http.ResponseWritter in Golang

阅读更多关于 Not buffered http.ResponseWritter in Golang

I'm writing a simple web app in Go and I want my responses to be streamed to the client (i.e. not buffered and sent in blocks once the request is fully processed) : func handle(res http.ResponseWriter, req *http.Request) { fmt.Fprintf(res, "sending first line of data") sleep(10) //not real code fmt.Fprintf(res, "sending second line of data") } From the client point of view, the two lines will be sent at the same time. Any suggestions are appreciated :) Edit after @dystroy answer It's possible to flush after each write I personally make, but in my use case it's not enough: cmd := exec.Command(

No console output on cout

问题 Good morning, I have a problem with Eclipse IDE for C/C++ Developers. I'm writting a smal tool for converting Strings. While testing on some point eclipse stopped to give console output . e.g.: cout<<"test"; doesn't get displayed. But it's not every where... another example: // File path as argument int main(int argc, char* argv[]) { if (argc != 2) { cout << "ERROR: Wrong amount of arguments! Only one allowed...\n"; cout << "\n" << "Programm closed...\n\n"; exit(1); } CommandConverter a(argv

Is this the proper way to flush the C input stream?

阅读更多关于 Is this the proper way to flush the C input stream?

Well I been doing a lot of searching on google and on here about how to flush the input stream properly. All I hear is mixed arguments about how fflush() is undefined for the input stream, and some say just do it that way, and others just say don't do it, I haven't had much luck on finding a clear efficient/proper way of doing so, that the majority of people agree on.. I am quite new at programming so I don't know all the syntax/tricks of the language yet, so my question which way is the most efficient/proper solution to clearing the C input stream?? Use the getchar() twice before I try to
