For other platforms/frameworks, inheritance and initialization should be done accordingly, not exactly like the examples. 8 | 9 | The class that handles instance invokation should inherit ISingleInstance and implement OnInstanceInvoked method. 10 | 11 | ## WPF 12 | E.g. in App class (`App.xaml.cs`): 13 | ```csharp 14 | public partial class App : Application, ISingleInstance 15 | { 16 | public void OnInstanceInvoked(string[] args) 17 | { 18 | // What to do with the args another instance has sent 19 | } 20 | // ... 21 | } 22 | ``` 23 | Initialization of instance should be done when application is starting, and cleanup method should be called on the exit point of the application. 24 | 25 | E.g. in App class (`App.xaml.cs`): 26 | ```csharp 27 | private void Application_Startup(object sender, StartupEventArgs e) 28 | { 29 | bool isFirstInstance = this.InitializeAsFirstInstance("soheilkd_ExampleIPC"); 30 | if (!isFirstInstance) 31 | { 32 | //If it's not the first instance, arguments are automatically passed to the first instance 33 | //OnInstanceInvoked will be raised on the first instance 34 | //You may shut down the current instance 35 | Current.Shutdown(); 36 | } 37 | } 38 | 39 | private void Application_Exit(object sender, ExitEventArgs e) 40 | { 41 | //Do not forget to cleanup 42 | SingleInstance.Cleanup(); 43 | } 44 | ``` 45 | 46 | ## Winforms 47 | Winforms doesn't have an Application.cs that could implement the `ISingleInstance` interface. We have to define one ourselves. 48 | ```csharp 49 | static class Program 50 | { 51 | [STAThread] 52 | static void Main(string[] args) 53 | { 54 | var app = new YourApplication(); 55 | 56 | var isFirstInstance = app.InitializeAsFirstInstance(nameof(YourApplication)); 57 | if (isFirstInstance) 58 | { 59 | try 60 | { 61 | app.Run(); 62 | } 63 | finally 64 | { 65 | SingleInstance.Cleanup(); 66 | } 67 | } 68 | } 69 | } 70 | 71 | class YourApplication : ISingleInstance 72 | { 73 | public void Run() 74 | { 75 | Application.SetHighDpiMode(HighDpiMode.SystemAware); 76 | Application.EnableVisualStyles(); 77 | Application.SetCompatibleTextRenderingDefault(false); 78 | Application.Run(new MainForm()); // Blocks until the main window is closed 79 | } 80 | 81 | public void OnInstanceInvoked(string[] args) 82 | { 83 | // What to do with the args another instance has sent 84 | } 85 | } 86 | 87 | ``` 88 | -------------------------------------------------------------------------------- /src/ISingleInstance.cs: -------------------------------------------------------------------------------- 1 | namespace SingleInstanceCore 2 | { 3 | public interface ISingleInstance 4 | { 5 | public void OnInstanceInvoked(string[] args); 6 | } 7 | } 8 | -------------------------------------------------------------------------------- /src/NativeMethods.cs: -------------------------------------------------------------------------------- 1 | using System; 2 | using System.ComponentModel; 3 | using System.Runtime.InteropServices; 4 | using System.Security; 5 | 6 | namespace SingleInstanceCore 7 | { 8 | [SuppressUnmanagedCodeSecurity] 9 | internal static class NativeMethods 10 | { 11 | /// 12 | /// Delegate declaration that matches WndProc signatures. 13 | /// 14 | public delegate IntPtr MessageHandler(WM uMsg, IntPtr wParam, IntPtr lParam, out bool handled); 15 | 16 | [DllImport("shell32.dll", EntryPoint = "CommandLineToArgvW", CharSet = CharSet.Unicode)] 17 | private static extern IntPtr CommandLineToArgvW([MarshalAs(UnmanagedType.LPWStr)] string cmdLine, out int numArgs); 18 | 19 | [DllImport("kernel32.dll", EntryPoint = "LocalFree", SetLastError = true)] 20 | private static extern IntPtr LocalFree(IntPtr hMem); 21 | 22 | 23 | public static string[] CommandLineToArgvW(string cmdLine) 24 | { 25 | IntPtr argv = IntPtr.Zero; 26 | try 27 | { 28 | argv = CommandLineToArgvW(cmdLine, out var numArgs); 29 | if (argv == IntPtr.Zero) 30 | throw new Win32Exception(); 31 | 32 | var result = new string[numArgs]; 33 | 34 | for (var i = 0; i < numArgs; i++) 35 | { 36 | IntPtr currArg = Marshal.ReadIntPtr(argv, i * Marshal.SizeOf(typeof(IntPtr))); 37 | result[i] = Marshal.PtrToStringUni(currArg); 38 | } 39 | 40 | return result; 41 | } 42 | finally 43 | { 44 | _ = LocalFree(argv); 45 | } 46 | } 47 | } 48 | } -------------------------------------------------------------------------------- /src/ObsoleteSingleInstance.cs: -------------------------------------------------------------------------------- 1 | using System; 2 | using System.Collections.Generic; 3 | using System.IO; 4 | using System.Text; 5 | using System.Threading; 6 | using System.Windows; 7 | using TinyIpc.Messaging; 8 | 9 | namespace SingleInstanceCore 10 | { 11 | [Obsolete("Use non-generic SingleInstance class instead.
