Splash screen c#

Question

I'm not so advanced in c# and I make small projects, but now I have a problem. I make a splash screen. Everything work. I make a project with a menu, and in menu you can choose different variants: Encryption, Decrpytion and Exit. In each, I have a "home" button. When I press button, in every menu, every time appear that splash screen and I need to wait. It's annoying. How can I set to work just 1 time (just when I start the program)?

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using Soft.Properties;
using System.Threading;

namespace Soft
{
    public partial class Meniu : Form
    {
    public Meniu()
    {
        Thread t = new Thread(new ThreadStart(SplashStart));
        t.Start();
        Thread.Sleep(5000);

        InitializeComponent();

        t.Abort();

    }

    public void SplashStart()
    {
        Application.Run(new LOGO());
    }

And one more question. After the Logo appear, the program minimize. Any advice?

Answer 1

If you want show splash screen only on program starting open your Program.cs and add a counter inside static class Program section for count form runs.

public static int counter=0;

And edit your code like this:

public Meniu()
        {
            InitializeComponent();
            Program.counter++;
            if (Program.counter == 1) // If first run minimize and show splash screen
            {
                this.WindowState = FormWindowState.Minimized;
                Thread t = new Thread(new ThreadStart(SplashStart));
                t.Start();
                Thread.Sleep(5000);
                t.Abort();
            }
            else // If not first run
            {
                this.WindowState = FormWindowState.Normal;
            }
        }

        public void SplashStart()
        {
           Application.Run(new LOGO());
        }

您可以在首次启动时设置运行时标志，并为下次启动设置时间戳，以表明您的应用程序已在运行，无需显示启动屏幕，只需在不同功能之间切换即可。

You can also use WindowsFormsApplicationBase from Microsoft.VisualBasic.ApplicationServices namespace. It's available in Winforms projects. This base class provide easy way to add splash screen into your app.
