Hi,

I understand that a class needs to be created in order to do this.  But what if there is nothing to return? Say, I just want to have a msg box popup?

thanks

In general, you can do "whatever" you want in the class, you can call a method in a class to do a message pop up, or return some objects, or variables if you want to,or you can even call a method of a class to accomplish something but without return anything.

all depends on what you want to do with your self-defined class.

I am testing a method. But I am getting error

CS1520: Method must have a return type

public class test
{
	public test1()
	{
        protected void test_Click(object sender, EventArgs e)
        {

             System.Windows.Forms.MessageBox.Show("HERE");



        }
	}
}

Open in new window

are you trying to do this in asp.net? if yes, try this:

web front:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="test.aspx.cs" Inherits="test" %>
...
<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Button" />

Open in new window

code behind:
public partial class test : System.Web.UI.Page
    {
        protected void Button1_Click(object sender, EventArgs e)
        {
            ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "msg", "alert('HERE')", true);
        }
    }

Open in new window


MessageBox is used for window applications

It works.  thank you.

What if there are a few function I would like to share across the board?  Is there a way to do it?  thanks

yes, you can similarly. but you probably need to defined shared (static) classes then.

as a start, you can refer to:
