prompt

问题 I have been struggling with a pretty simple issue writing a little program in C . Getting input (commands, arguments, flags to be executed) via fgets() works fine as long as the size of the input does not exceed 1024 bytes. After 1024 characters are typed, no more characters are accepted -- the prompt just stops. I assume reason for the problem doesn't lay in the fgets() parameters/configuration because otherwise it would at least take the input up to defined size instead of blocking. How can

问题 I want to compile C code from the Command Prompt in Windows. I have added the environment variable to the PATH and I can compile .cs files with: csc app.cs That's OK, but how do I compile app.c? 回答1: You do this: cl app.c Here's a complete transcript, including setting up the environment for Visual Studio 2005 (change "8" to "9.0" for Visual Studio 2008). C:\src\tests>"\Program Files (x86)\Microsoft Visual Studio 8\vc\bin\vcvars32.bat" Setting environment for using Microsoft Visual Studio

问题 I am using System.Windows.Forms but strangely enough don't have the ability to create them. How can I get something like a javascript prompt dialog, without javascript? MessageBox is nice, but there is no way for the user to enter an input. I want the user to enter any text input possible. 回答1: You need to create your own Prompt dialog. You could perhaps create a class for this. public static class Prompt { public static string ShowDialog(string text, string caption) { Form prompt = new Form(

问题 So, I've been trying to customize by bash prompt so that it will look like [feralin@localhost ~]$ _ with colors. I managed to get constant colors (the same colors every time I see the prompt) but I want the username ('feralin') to appear red, instead of green, if the last command had a nonzero exit status. I came up with: \e[1;33m[$(if [[ $? == 0 ]]; then echo "\e[0;31m"; else echo "\e[0;32m"; fi)\u\e[m@\e[1;34m\h \e[0;35m\W\e[1;33m]$ \e[m However, from my observations, the $(if ...; fi)

问题 I'm trying to replace STDIN with readline. If I use STDIN (like in comment, see code) the cursor is ready for input right after printf output in the same line . But using readline the printf output is somehow gone and only the readline prompt is visible. I can insert a "print "\n";" (commented out) in the next line to printf which moves the prompt to the next line and printf output is visible. But, I want to have a formated prompt and the cursor directly after the prompt ( same line ). The

问题 I was trying to re-prompt a user's input and reuse it. Here's the code sample: print "Please put your string here!" user_input = gets.chomp user_input.downcase! if user_input.include? "s" user_input.gsub!(/s/,"th") elsif user_input.include? "" user_input = gets.chomp puts "You didn't enter anything!Please type in something." user_input = gets.chomp else print "no \"S\" in the string" end puts "transformed string: #{user_input}!" My elsif will let the user know that their input was not

问题 I'm having a bit of trouble trying to run a java class on the command prompt. Its a very simple class and a friend of mine says it could be a problem with windows 8. Are there any suggestions. Here i'll show you the class and how I tried to compile it. I works fine in eclipse. package gmit; public class A { public static void main(String[] args) { System.out.println("hello"); } } In the command prompt I wrote C:\Users\eclipse\workspace\Oct1stcasting\src\gmit> followed by - javac A.java java A

问题 I'm working on a JavaScript assignment that requires me to use prompt-synch in Node.JS. It works fine until I try to use a newline character \n within the prompt, at which point every character or backspace typed causes the prompt to repeat itself. What could I do to get the user input to appear on a new line (a requirement of this exercise) without this issue? Problem code: if (guess < answer) { guess = prompt("Too low!\n> "); } else if (guess > answer) { guess = prompt("Too high!\n> "); }

问题 I can't make RepromptDialogAsync() to work. When dialog b is chosen it should re-prompt the choice prompt showing all the choices again. But when choosing dialog b it is doing nothing. Am I doing it wrong? I can't find any RepromptDialogAsync() tutorial on docs. Any help would be greatly appreciated. Thank you! Code: public class MainDialog : ComponentDialog { private const string InitialId = "mainDialog"; private const string ChoicePrompt = "choicePrompt"; private const string DialogAId =

问题 So I am writing an application that iterates through a specified directory tree and I was experimenting with the exception that handles permissions for folder access and there was one folder I came across that the compiler returned that had the directory of C:\ProgramData\Application Data Does anyone know what this folder is? It doesn't seem to exist within Windows Explorer. Like, the folder isn't there. It's not hidden. It just isn't there. I was able to get inside the folder using an
