Verwenden von Microsoft.visualBasic.Applicationsservices zur Verwaltung der Einzelinstanz einer Anwendung

Question

Ich habe es geschafft, den folgenden Code von Stackoverflow zu finden:

using Microsoft.VisualBasic.ApplicationServices;
using System.Windows.Forms;

namespace ExciteEngine2.MainApplication {

    public class SingleInstanceController: WindowsFormsApplicationBase {

        public delegate Form CreateMainForm();
        public delegate void StartNextInstanceDelegate(Form mainWindow);
        private readonly CreateMainForm formCreation;
        private readonly StartNextInstanceDelegate onStartNextInstance;

        public SingleInstanceController() {

        }
        public SingleInstanceController(AuthenticationMode authenticationMode)
            : base(authenticationMode) {

        }

        public SingleInstanceController(CreateMainForm formCreation, StartNextInstanceDelegate onStartNextInstance) {
            // Set whether the application is single instance
            this.formCreation = formCreation;
            this.onStartNextInstance = onStartNextInstance;
            IsSingleInstance = true;

            StartupNextInstance += this_StartupNextInstance;
        }

        private void this_StartupNextInstance(object sender, StartupNextInstanceEventArgs e) {
            if (onStartNextInstance != null) {
                onStartNextInstance(MainForm); 
                // This code will be executed when the user tries to start the running program again,
                // for example, by clicking on the exe file.
                // This code can determine how to re-activate the existing main window of the running application.
            }
        }

        protected override void OnCreateMainForm() {
            // Instantiate your main application form
            MainForm = formCreation();
        }

        //public void Run() {
        //  string[] commandLine = new string[0];
        //  base.Run(commandLine);
        //}

        protected override void OnRun() {
            base.OnRun();
        }

    }

}

Und ich habe das in meinem Program.cs:

    private static Form CreateForm() {
        return new AppMDIRibbon();
    }

    private static void OnStartNextInstance(Form mainWindow)            
    {
        // When the user tries to restart the application again, the main window is activated again.
        mainWindow.WindowState = FormWindowState.Maximized;
    }

    [STAThread]
    static void Main(string[] args) {

        SingleInstanceController ApplicationSingleInstanceController = new SingleInstanceController(CreateForm, OnStartNextInstance);           
        ApplicationSingleInstanceController.Run(args);   

        #region Application Logic
        #endregion
    }

Jetzt habe ich eine Menge Anwendungslogik, die ich vor dem Run () benötige:

        #region Application Logic
        //Uninstall
        foreach (string arg in args) {
            if (arg.Split('=')[0] == "/u") {
                ApplicationLogger.Info("Uninstallation command received.");
                Process.Start(new ProcessStartInfo(Environment.GetFolderPath(Environment.SpecialFolder.System) + "\\msiexec.exe", "/x " + arg.Split('=')[1]));
                return;
            }
        }

        SetupXPO();
        SetupLogging();

        Thread.CurrentThread.CurrentCulture = new CultureInfo("en-GB");
        Thread.CurrentThread.CurrentUICulture = new CultureInfo("en-GB");

        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);

        Application.ThreadException += Application_ThreadException;

        try {
            ApplicationLogger.Info("Setting Telerik Theme: " + ConfigurationManager.AppSettings["ThemeToUse"]);
            ThemeResolutionService.ApplicationThemeName = ConfigurationManager.AppSettings["ThemeToUse"];

        }
        catch (Exception ex) {
            ApplicationLogger.Error("Exception while setting Telerik Theme.", ex);
            ThemeResolutionService.ApplicationThemeName = "ControlDefault";

        }

        DevExpress.UserSkins.OfficeSkins.Register();
        DevExpress.UserSkins.BonusSkins.Register();
        DevExpress.Skins.SkinManager.EnableFormSkins();
        DevExpress.Skins.SkinManager.EnableMdiFormSkins();

        if (args.Contains("/dx")) {
            Application.Run(new AppMDIRibbonDX());
            ApplicationLogger.Info("Application (DX) started.");

        }
        else {
            Application.Run(new AppMDIRibbon());
            ApplicationLogger.Info("Application started.");

        }
        #endregion

Wie kann ich diese Logik einrichten? Ich verwende ein Commandline -Argument, um tatsächlich eine alternative Form zu starten. Ich verwende ein Commandline -Argument, um eine Deinstallation zu verursachen, und rufe auch eine Methode zum Einrichten von DB und Protokollierung auf. Ebenso richte ich auch Kultur und Themen auf. All dies vor der tatsächlichen Anwendung. Kann jemand vorschlagen?

Wenn Sie die von Ihnen verlinkte visuelle Basic-Klasse vereinfachen, können Sie Ihren aktuellen Anruf nur an application.run () ersetzen. Dies hängt davon ab, wie Sie nachfolgende Instanzen bewältigen möchten.

Ändern Sie mit der folgenden Version einfach Sie rufen Sie an: application.run (myForm) in SingleInInstanceApplication.run (myForm);

public sealed class SingleInstanceApplication : WindowsFormsApplicationBase
{
    private static SingleInstanceApplication _application;

    private SingleInstanceApplication()
    {
        base.IsSingleInstance = true;
    }

    public static void Run(Form form)
    {
        _application = new SingleInstanceApplication {MainForm = form};

        _application.StartupNextInstance += NextInstanceHandler;
        _application.Run(Environment.GetCommandLineArgs());
    }

    static void NextInstanceHandler(object sender, StartupNextInstanceEventArgs e)
    {
        // Do whatever you want to do when the user launches subsequent instances
        // like when the user tries to restart the application again, the main window is activated again.
        _application.MainWindow.WindowState = FormWindowState.Maximized;
    }
}

Dann enthält Ihre main () -Methode Ihre "Anwendungslogik"

   [STAThread]
    static void Main(string[] args) {

        #region Application Logic
        //Uninstall
        foreach (string arg in args) {
            if (arg.Split('=')[0] == "/u") {
                ApplicationLogger.Info("Uninstallation command received.");
                Process.Start(new ProcessStartInfo(Environment.GetFolderPath(Environment.SpecialFolder.System) + "\\msiexec.exe", "/x " + arg.Split('=')[1]));
                return;
            }
        }

        SetupXPO();
        SetupLogging();

        Thread.CurrentThread.CurrentCulture = new CultureInfo("en-GB");
        Thread.CurrentThread.CurrentUICulture = new CultureInfo("en-GB");

        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);

        Application.ThreadException += Application_ThreadException;

        try {
            ApplicationLogger.Info("Setting Telerik Theme: " + ConfigurationManager.AppSettings["ThemeToUse"]);
            ThemeResolutionService.ApplicationThemeName = ConfigurationManager.AppSettings["ThemeToUse"];

        }
        catch (Exception ex) {
            ApplicationLogger.Error("Exception while setting Telerik Theme.", ex);
            ThemeResolutionService.ApplicationThemeName = "ControlDefault";

        }

        DevExpress.UserSkins.OfficeSkins.Register();
        DevExpress.UserSkins.BonusSkins.Register();
        DevExpress.Skins.SkinManager.EnableFormSkins();
        DevExpress.Skins.SkinManager.EnableMdiFormSkins();

        if (args.Contains("/dx")) {
            SingleInstanceApplication.Run(new AppMDIRibbonDX());
            ApplicationLogger.Info("Application (DX) started.");

        }
        else {
            SingleInstanceApplication.Run(new AppMDIRibbon());
            ApplicationLogger.Info("Application started.");

        }
        #endregion
    }
