问题 This question already has answers here : WinAPI C++ client detect write on anonymous pipe before reading (3 answers) Closed 6 years ago .

问题 I have looked here https://msdn.microsoft.com/en-us/library/system.diagnostics.processstartinfo.createnowindow(v=vs.110).aspx And I understand that A) Not every program respects it CreateNoWindow request and B) It requires UseShellExecute=False (default is true). C) It is meant to indicate whether a window is created. (it won't ever hide the parent window). It's speaking of whether a window is created for the child process. (msdn says 'new window') D) CreateNoWindow defaults to false. I am

问题 Adapting Apache WeatherTelnet code, I'm working towards a MUD client, but am struggling with concurrent input/output. It's not possible to read and write simultaneously, of course. For this application, out should have priority over in . If nothing is being written to java.lang.System.out then, and only then, should input from java.lang.System.in be read. I'm just not sure how to accomplish that because in and out are interwoven. run and memory dump: thufir@dur:~$ thufir@dur:~$ thufir@dur:~$

问题 I am trying to make a simple calculator with arrays in C#. Firstly I tried making it using two integers and one operator only and it worked well. Now I am trying to do so that the user can make the expression as long as they like. For example 7 * 7 + 1 / 50 instead of a simple 9 + 8 which includes only one operator and two integers.

问题 string choice = String.ToUpper(Console.ReadLine()); I want to input a string and convert it to upper case. However, there's an error that states : cannot convert from 'string' to System.Globalization.CultureInfo' that appears when I hover over the Console.ReadLine() . Why doesn't this work , and what fixes are there? And is there another way to do this ? 回答1: String.ToUpper is an instance method, that means you have to use it "on" your string: string input = Console.ReadLine(); string choice

问题 I have a program for a client that needs to run one set of code every 30 minutes via a scheduled task. at 1:30 am it needs to run a separate set of code. Both sets of code will generate a file and place it in a directory. How do I set it up to be able to run two sets of SQL code? I could do it getting the current date time and comparing it but that seems bulky to me. Is there a way a schedule task can run a program which would pass in something to my Main(string[] args)? Is there a correct

问题 THE SETTING: A Console program, in .net I am using readkey in a loop, which rewrites to the same line on the screen (Console.setCursorPosition) however, if I type Enter, the Console pushes the text upwards, which is the usual command line behaviour. THE QUESTION: Is it possible to trap a key press (that Enter), so that my program will get the key, but the Console does not? The environment is Linux, with Mono (and the program is supposed to be cross platform). so low level windows driver
