console

问题 I want to have a JTextArea that can completely work instead of a console but I don't know how to do this! Thank you 回答1: The solution to the problem is to redirect System.{in,out,err} to a JTextArea . Starting with System.out it's pretty straight forward to to redirect it to your JTextArea component using System.setOut method. In the example below I've done this using pipes and SwingWorker but that is all fancy stuff to actually get the output simpler to the swing component. Emulating System

问题 How can I bring a console application window to front in C# (especially when running the Visual Studio debugger)? 回答1: It's hacky, it's horrible, but it works for me (thanks, pinvoke.net!): using System; using System.Diagnostics; using System.Runtime.InteropServices; using System.Threading; public class Test { [DllImport("user32.dll")] [return: MarshalAs(UnmanagedType.Bool)] static extern bool SetForegroundWindow(IntPtr hWnd); [DllImport("user32.dll", EntryPoint="FindWindow", SetLastError =

问题 For whatever reason, the Ruby on Rails console refuses to start; it just hangs. I haven't made any changes to my code, and other projects using the same version of Ruby and Ruby on Rails have no issue. When I finally Ctrl + C I get this stack trace, which points to Spring. I can't explain why this is happening from one moment to the next, where it was working fine. I have cleared out all the gems through RVM and reinstalled all through bundle command, but still no luck. Any ideas would be

问题 Does Console.WriteLine block until the output has been written or does it return immediately?

The idea is to queue up the

问题 I frequently start with a simple console application to try out an idea, then create a new GUI based project and copy the code in. Is there a better way? Can I convert my existing console application easily? 回答1: Just add a new Winform, add the following code to your Main : Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new Form1()); Also, be sure the [STAThread] attribute is declared above your Main function to indicate the COM

问题 I am using this answer to print a progress bar but want it to print what exactly it is doing while it is progressing. I added a parameter called "current_task" to print_progress() and now would like it to perform as follows. How do I do this? FYI: I'm on on a Unix system: macOS Sierra print_progress(7,10,...remaining params..., "downloading contacts") should print this Currently downloading contacts Progress |████████████████████████████████---------------------| 70% Complete the subsequent
