I've just started to learn programming in C# and I have a problem. I made a simple application (just a window with two buttons). One button starts another program and the other button shows this window again in 2 minutes (it's a sort of reminder). There's no X button, but it can still be closed by ALTF4 which I want to disable.

I've tried e.Cancel = true;, but I am obviously doing something wrong. What I did was doubleclick on the main window, then void MainFormLoad(object sender, EventArgs e) appeared in the code and I changed EventArgs e to FormClosingEventArgs and pasted the above e.Cancel = true; in there.

I am getting the following error:

No overload for 'MainFormLoad' matches delegate 'System.EventHandler' (CS0123)

It refers me to this line in MainForm.Designer.cs:

this.Load += new System.EventHandler(this.MainFormLoad);

Here's the whole code:

using System;
using System.Diagnostics;
using System.Collections.Generic;
using System.Drawing;
using System.Windows.Forms;

namespace Reminder

 /// <summary>
 /// Description of MainForm.
 /// </summary>
 public partial class MainForm : Form
 
 public MainForm()
 
 //
 // The InitializeComponent() call is required for Windows Forms designer support.
 //
 InitializeComponent();

 //
 // TODO: Add constructor code after the InitializeComponent() call.
 //
 
 int duration = 0;
 void Timer1Tick(object sender, EventArgs e)
 
 duration++;
 System.Diagnostics.ProcessStartInfo start = new System.Diagnostics.ProcessStartInfo();
 start.FileName = @"C:ThisProgram.exe";
 Process.Start(start);
 Application.Exit();
 if (duration == 1)
 
 Timer.Stop();
 
 
 void LaterClick(object sender, EventArgs e)
 
 Timer.Enabled = true;
 Timer.Start();
 Hide();
 
 void OKClick(object sender, EventArgs e)
 
 System.Diagnostics.ProcessStartInfo start = new System.Diagnostics.ProcessStartInfo();
 start.FileName = @"C:OtherExternalProgram.exe";
 Process.Start(start);
 Application.Exit();
 
 void MainFormLoad(object sender, FormClosingEventArgs e)
 
 e.Cancel = true;
 
 

And here is the MainForm.Designer.cs code:

namespace Reminder

 partial class MainForm
 
 /// <summary>
 /// Designer variable used to keep track of non-visual components.
 /// </summary>
 private System.ComponentModel.IContainer components = null;
 private System.Windows.Forms.Button OK;
 private System.Windows.Forms.Timer Timer;
 private System.Windows.Forms.Button Later;

 /// <summary>
 /// Disposes resources used by the form.
 /// </summary>
 /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
 protected override void Dispose(bool disposing)
 
 if (disposing) 
 if (components != null) 
 components.Dispose();
 
 
 base.Dispose(disposing);
 

 /// <summary>
 /// This method is required for Windows Forms designer support.
 /// Do not change the method contents inside the source code editor. The Forms designer might
 /// not be able to load this method if it was changed manually.
 /// </summary>
 private void InitializeComponent()
 
 this.components = new System.ComponentModel.Container();
 System.ComponentModel.ComponentResourceManager resources = new System.ComponentModel.ComponentResourceManager(typeof(MainForm));
 this.OK = new System.Windows.Forms.Button();
 this.Timer = new System.Windows.Forms.Timer(this.components);
 this.Later = new System.Windows.Forms.Button();
 this.SuspendLayout();
 // 
 // OK
 // 
 this.OK.Location = new System.Drawing.Point(12, 253);
 this.OK.Name = "OK";
 this.OK.Size = new System.Drawing.Size(75, 23);
 this.OK.TabIndex = 0;
 this.OK.Text = "OK";
 this.OK.UseVisualStyleBackColor = true;
 this.OK.Click += new System.EventHandler(this.OKClick);
 // 
 // Timer
 // 
 this.Timer.Interval = 24000;
 this.Timer.Tick += new System.EventHandler(this.Timer1Tick);
 // 
 // Later
 // 
 this.Later.Location = new System.Drawing.Point(425, 253);
 this.Later.Name = "Later";
 this.Later.Size = new System.Drawing.Size(75, 23);
 this.Later.TabIndex = 1;
 this.Later.Text = "Later";
 this.Later.UseVisualStyleBackColor = true;
 this.Later.Click += new System.EventHandler(this.LaterClick);
 // 
 // MainForm
 // 
 this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
 this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
 this.BackColor = System.Drawing.SystemColors.Window;
 this.BackgroundImage = ((System.Drawing.Image)(resources.GetObject("$this.BackgroundImage")));
 this.BackgroundImageLayout = System.Windows.Forms.ImageLayout.Zoom;
 this.ClientSize = new System.Drawing.Size(512, 288);
 this.Controls.Add(this.Later);
 this.Controls.Add(this.OK);
 this.Cursor = System.Windows.Forms.Cursors.Default;
 this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
 this.MaximizeBox = false;
 this.MinimizeBox = false;
 this.Name = "MainForm";
 this.ShowIcon = false;
 this.ShowInTaskbar = false;
 this.StartPosition = System.Windows.Forms.FormStartPosition.CenterScreen;
 this.TopMost = true;
 this.Load += new System.EventHandler(this.MainFormLoad);
 this.ResumeLayout(false);

 
 

Thank you in advance for your help.
