问题 I'm trying to write a Delphi console application that creates a TStream for its standard input, and another TStream for its standard output. (It will be launched by a host app with its input and output redirected to pipes, and will be passing binary data to/from that host app, so TStream will be much better-suited to the task than ReadLn/WriteLn.) How do I go about opening a TStream on standard input or standard output? 回答1: Off the top of my head: InputStream := THandleStream.Create

问题 Basically I want 200 characters maximum to come up in Console.ReadLine() for user input before characters start being suppressed. I want it like TextBox.MaxLength except for console input. How would I go about this? And I don't want to do input.Substring(0, 200). Solved: I used my own ReadLine function which was a loop of Console.ReadKey(). It looks like this, essentially: StringBuilder sb = new StringBuilder(); bool loop = true; while (loop) { ConsoleKeyInfo keyInfo = Console.ReadKey(true);

问题 code below creates a layout and displays some text in the layout. Next the layout is displayed on the console screen using raw display module from urwid library.

问题 My code is as follows // ConsoleApplication1.cpp : Defines the entry point for the console application. // #include <windows.h> #include "stdafx.h" int _tmain(int argc, _TCHAR* argv[]) { BYTE* pAlloc1 = NULL; return 0; } creating following errors. error C2065: 'BYTE' : undeclared identifier What am I doing wrong here? 回答1: You have #include "stdafx.h" , which usually means that you're using a precompiled header. If you use a precompiled header, anything preceding the precompiled header will

问题 When running a console application in Visual Studio, depending on your settings, it will add a prompt after the program exits: Press any key to continue . . . I have found how to detect if I am running under the debugger(use Debugger.IsAttached ), but it isn't helpful. Press CTRL-F5 to Start Without Debugging sets this flag to false , yet still shows the prompt . I want to detect this because I'd like to display my own message and wait for a keypress, but not double up keypress checks . I don

问题 I want to set cursor position to print a char on console screen. Is there a solution without using ncurses library. Is there an equivalent call for SetConsoleCursorPosition in Linux from example below: void print (int x, int y, char c) { COORD p = { x, y }; SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), p); printf("%c", c); } 回答1: Perhaps a little history is in order. What you call the “console” in Windows is really an example of a terminal emulator; however, unlike traditional

问题 In windows console application, one can catch pressing ctrl+c by using: #include <stdio.h> #include <signal.h> void SigInt_Handler(int n_signal) { printf("interrupted\n"); } int main(int n_arg_num, const char **p_arg_list) { signal(SIGINT, &SigInt_Handler); getchar(); // wait for user intervention } This works well, except it does not work at all if the user presses the cross × that closes the console window. Is there any signal for that? The reason I need this is I have this CUDA application
