5/13/2014 - By Pranav Singh 0

When ever we create a windows application on that case in some places we needed to restrict user for entering some value or need to display error message box with error icon and ok button. So in this article i will show you how you can display a error message box in windows application using c# and VB.Net
If you are using try catch block on that case also you can use this message box to display the message box.

Some of my previous articles are as follows:


so here is the code for this article.

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

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

        private void btnerror_Click(object sender, EventArgs e)
        {
            //Suppose we have error message "Sorry Please enter number only
            MessageBox.Show("Sorry Please enter number only", "Error Message", MessageBoxButtons.OK, MessageBoxIcon.Error);
        }
    }
}

VB.Net
Imports System
Imports System.Collections.Generic
Imports System.ComponentModel
Imports System.Data
Imports System.Drawing
Imports System.Linq
Imports System.Text
Imports System.Windows.Forms

Namespace ErrorMesssage
    Partial Public Class Form1
        Inherits Form
        Public Sub New()
            InitializeComponent()
        End Sub

        Private Sub btnerror_Click(ByVal sender As Object, ByVal e As EventArgs)
            'Suppose we have error message "Sorry Please enter number only
            MessageBox.Show("Sorry Please enter number only", "Error Message", MessageBoxButtons.OK, MessageBoxIcon.[Error])
        End Sub
    End Class
End Namespace

Now run the demo for output


now click on button to display the message.
