C# closing a form from another form

Question

Hi guys, is there any way to close a Form from another form. I've Form1, I fill all the text box. I use the button click to open the Form2 which retrieve the last row inserted (from Form1). The user can not confirm so I use this.close in the Form2 and so the user can amend the Form1. The problem comes when the user confirm. In this case I'd like to close the Form1 with the data inserted. I can open a new Form1 but the previous Form would be available. So what I am trying to do is to close the Form1 using the button confirm in the Form2.

Is it possible?

Thanks

 

Answer 1

Hello,

Is form1 the main form that opened the application?

Answer 2

At the moment yes (I am developing) but it is not supposed to be. I can change it.

Answer 3

The reason for asking is that whatever form starts the application, when closed will close the application. If you examine Program.cs

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

namespace WindowsFormsApplication1
{
    static class Program
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new Form1());
        }
    }
}

Application.Run fires up Form1 then when you close Form1 a call is made ExecuteThread which closes the app.

With that you might consider a different approach. My question now is why can't the user confirm from Form2?

Answer 4

Thanks Karen. I will put Form3 as main. Hence which code should I use in order to achieve the schema previously mentioned?

Answer 5

Perhaps a conceptual example might help that shows a simple example to pass data and confirm user input. I may be off base here so let me know.

Answer 6

Thanks, Karen. I'll have a look. However I thought was simpler to close a form from another form but apparently is not.
