Visual Studio C# 2015 does not debug

Question

Here’s what I’m trying to do:

1. I compile the program by clicking start;
2. The screen splash is displayed, the progress bar rotates and reaches 100% (closes the screen splash);

3. Opens the screen of login, the identification is placed and everything happens correctly (the identification screen is closed);

4. Open the screen home (main), and when closing the screen home for X (not yet put the other buttons) Visual Studio keeps running, the compilation does not stop until I press the stop button of Visual Studio.

What would you like to happen, when entering user and password, the screen login was closed and only the screen appeared home.

What am I doing wrong??

namespace App.Sis_Igreja
{
    static class Program
    {

            Application.Run(new SplashScreen());

Follow the Splash form

    {
        public SplashScreen()
        {
            InitializeComponent();
        }

        private void progressBar1_Click(object sender, EventArgs e)
        {

        }

        private void timer1_Tick(object sender, EventArgs e)
        {
            lb_porcentagem.Text = pb_splash.Value + "%";

            if (pb_splash.Value < 100)
            {
                pb_splash.Value = pb_splash.Value + 2;
            }
            else
            {
                timer1.Enabled = false;
                frm_inicial frm = new frm_inicial();
                frm.Show();
                this.Visible = false;
                //comentario
            }
        }
    }
}

Answer 1

The problem is that you start the application with Splashscreen, this causes the application to continue running after you close the other Forms, possibly after the login you are giving a Hide() in Splash.

If your main application form is the frm_gerenciamento he who must be in Application.Run(new frm_gerenciamento()); and not the SplashScreen.

To do this, something like this can be done:

No Program.Cs:

    static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);


        FormLogin form = new FormLogin();
        if (form.ShowDialog() == DialogResult.OK)
        {
             Application.Run(new frm_gerenciamento());
        }
        else
            Application.Exit();
    }

No Formlogin:

   Load()
   {
      //Mostra sua splashScreen se quiser... 
   }

   btnLogin_click()
   {
      if([validar login])
      {
          this.DialogResult = DialogResult.OK;
      }
      else 
          //Login inválido

   }

   btnCancelar_click()
   {
       this.DialogResult = DialogResult.Cancel;
   }

Answer 2

You can start your application without specifying an instance of Form to the method Run, giving Show in the frm before the Run. Thus:

static class Program
{
    [STAThread]
    static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);

        var frm = new Form1();
        frm.Show();

        Application.Run();
    }
}

In doing so, you have to call Application.Exit() explicitly to terminate the application.

You can implement Forms to do this automatically when the open Forms count is zero (Application.OpenForms.Count == 0). For this you will need to implement the event OnFormClosed on all Forms. For example:

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        var frm = new Form1();
        frm.Show();
        this.Close();
    }

    protected override void OnFormClosed(FormClosedEventArgs e)
    {
        base.OnFormClosed(e);
        if (Application.OpenForms.Count == 0)
            Application.Exit();
    }
}
