Hide/show Button at runtime

Question

I need your help with c# and some graphic issues: I'm developing a very simple application. There is a unique form called DeltaPregView, a controller for the form called DeltaPregController and a class that contains the Main of the project:

Main Class:

using System;
using System.Linq;
using System.Collections.Generic;
using System.Windows.Forms;

namespace deltaPreg
{
    static class Program
    {
        [MTAThread]
        static void Main()
        {
            //create the view
            DeltaPregView view = new DeltaPregView();
            //link the view to the APP
            Application.Run(view);
            //initialize the controller of the APP
            DeltaPregController controller = new DeltaPregController(view);
        }
    }
}

View for the class:

using System;
using System.Linq;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace deltaPreg
{
    public partial class DeltaPregView : Form
    {
        public DeltaPregView()
        {
            InitializeComponent();

        }

        public void init()
        {
            prova.Visible = false;
        }

    }
}

and the Controller for the view:

using System;
using System.Linq;
using System.Collections.Generic;
using System.Text;

namespace deltaPreg
{
    class DeltaPregController
    {
        #region variables
        private DeltaPregView view;
        #endregion

        public DeltaPregController(DeltaPregView view)
        {
            this.view = view;
            //start the reading process
            start();
        }
        private void start()
        {
            view.init();
        }
    }
}

I would like to hide the button called "prova", but nothing changes in my program. I'm a newbie in the winforms management, thank you in advance.

Answer 1

The problem is that you print the form before you call the init function in DeltaPregView.

One way to solve this is by replacing those lines:

    //link the view to the APP
    Application.Run(view);
    //initialize the controller of the APP
    DeltaPregController controller = new DeltaPregController(view);

To:

    //initialize the controller of the APP
    DeltaPregController controller = new DeltaPregController(view);
    //link the view to the APP
    Application.Run(view);
