How do I print UTF-8 from c++ console application on Windows

阅读更多关于 How do I print UTF-8 from c++ console application on Windows

问题 For a C++ console application compiled with Visual Studio 2008 on English Windows (XP,Vista or 7). Is it possible to print out to the console and correctly display UTF-8 encoded Japanese using cout or wcout? 回答1: The Windows console uses the OEM code page by default to display output. To change the code page to Unicode enter chcp 65001 in the console, or try to change the code page programmatically with SetConsoleOutputCP. Note that you probably have to change the font of the console to one

.NET Console Application Exit Event

阅读更多关于 .NET Console Application Exit Event

In .NET, is there a method, such as an event, for detecting when a Console Application is exiting? I need to clean up some threads and COM objects. I am running a message loop, without a form, from the console application. A DCOM component that I am using seems to require that the application pump messages. I have tried adding a handler to Process.GetCurrentProcess.Exited and Process.GetCurrentProcess.Disposed. I have also tried adding a handler to Application.ApplicationExit and Application.ThreadExit events, but they are not firing. Perhaps that is because I am not using a form. You can use

阅读更多关于 How to run a C# console application with the console hidden

问题 Is there a way to hide the console window when executing a console application? I am currently using a Windows Forms application to start a console process, but I don\'t want the console window to be displayed while the task is running. 回答1: If you are using the ProcessStartInfo class you can set the window style to hidden - in the case of console (not GUI) applications, you have to set CreateNoWindow to true : System.Diagnostics.ProcessStartInfo start = new System.Diagnostics

问题 I am new to asynchronous programming with the async modifier. I am trying to figure out how to make sure that my Main method of a console application actually runs asynchronously. class Program { static void Main(string[] args) { Bootstrapper bs = new Bootstrapper(); var list = bs.GetList(); } } public class Bootstrapper { public async Task<List<TvChannel>> GetList() { GetPrograms pro = new GetPrograms(); return await pro.DownloadTvChannels(); } } I know this is not running asynchronously

Java gotoxy(x,y) for console applications

阅读更多关于 Java gotoxy(x,y) for console applications

问题 I\'m writing a simple console application (80x24) in Java, is there a gotoxy(x,y) equivalent? 回答1: If by gotoxy(x,y), you want to reposition your cursor somewhere specific on the console, you can usually use VT100 control codes to do this. See http://www.termsys.demon.co.uk/vtansi.htm. Do something like char escCode = 0x1B; int row = 10; int column = 10; System.out.print(String.format("%c[%d;%df",escCode,row,column)); Which should move the cursor to position 10,10 on the console. 回答2: I don't

Global hotkey in console application

阅读更多关于 Global hotkey in console application

问题 Does anyone know how to use the RegisterHotKey/UnregisterHotKey API calls in a console application? I assume that setting up/removing the hotkey is the same, but how do I get the call back when the key was pressed? Every example I see is for Winforms, and uses protected override void WndProc(ref Message m){...} , which isn\'t available to me. update: what I have is below, but the event is never hit. I thought it could be because when you load ConsoleShell it does block further execution, but
