C# programs Even if I have to use some code, how to I force a form that I have created to open before the MainForm loads. So I want this window to open before anything else.

now I am in the properties section, I remember back in vb6 I could just specify a form but in .net I can’t see that option, any help please?

I needed to go to the programs.cs file and specify which form to load before the main form.

The Usual Suspect: Program.cs C# programs

By default, in a Windows Forms application, the Program.cs file contains the entry point for the application. This is where the main form is typically loaded using Application.Run(new MainForm());.

The Plot Twist: Load a Different Form First ?

If you want to show a different form first, you can do it right in the Program.cs file. Here’s a simple way to load a login form before the main form:

using System;
using System.Windows.Forms;

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

            // Show the login form
            LoginForm loginForm = new LoginForm();
            if (loginForm.ShowDialog() == DialogResult.OK)
            {
                // If login is successful, show the main form
                Application.Run(new MainForm());
            }
        }
    }
}

In this example, the login form (LoginForm) is displayed first. If the user successfully logs in, the login form will close with DialogResult.OK, and the main form (MainForm) will then be displayed.

This approach lets you control the flow of your application right from the get-go. It’s pretty handy for scenarios where you need some kind of user validation or initial setup before the main form loads. Just make sure the first form you show sets the stage well for what’s to come!

In Closing

And there you have it—a simple way to specify which form should load first in a C# Windows Forms application. It’s a small tweak, but sometimes the order of the show can make all the difference. Thanks for coding along, and rock on with your C# journey! ??

You go to project properties and specify starting form.
