My "Hello World" in ASP

I have written my first "Hello World" program in ASP. I thought I would post here how it is done and ask if anyone can suggest how to incorporate C#.

The first step was to download the free "Microsoft Visual Web Developer 2005 Express Edition" from microsoft.com

The next step was to install and run this program. Then create a new web page by clicking on File -> New Web Page. This will bring up this windowL

From this window, pick "ASP.Net Web Site" and click the OK button.

Then I edited the Default.aspx file so it reads like this:

Code: Select all

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %>
<%
    HelloWorldLabel.Text = "Hello, world!"
%>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="www.w3.org/1999/xhtml" >
<head runat="server">
    <title>Untitled Page</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
    <asp:Label runat="server" id="HelloWorldLabel"></asp:Label>

    </div>
    </form>
</body>
</html>

And this works.

So the next step is to incorporate C# into this "Hello World" program. Can anyone make a suggestion?

Would changing VB to C# and the VB to C# code work?

I have no idea whether it actually works, but you could try

Code: Select all

<%@ Page Language="C#" AutoEventWireup="false" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<%
    HelloWorldLabel.Text = "Hello, world!";
%>

Visual Studio 2008 Express has been released, and gives you access to C#3/VB9 and a host of new features. (You can still target .NET 2.0 runtimes if you need to, though). Websites tend to be data driven, and LINQ is therefore quite appealing.

On the web development front, you'll also get access to Silverlight.

As for a C# website... I just fired up VWD and picked "Visual C#" from the "Language" dropdown.

Generally, you should try and separate the logic from the interface. If you expand the Default.aspx file you should see a code file, Default.aspx.cs (or .vb in your case). You can put the code in there, like this:

Code: Select all

using System;

public partial class _Default : System.Web.UI.Page 
{
    protected void Page_Load(object sender, EventArgs e)
    {
        this.HelloWorldLabel.Text = "Hello, World";
    }
}

Hm, I really should get around to learning ASP.NET properly, but my host only supports PHP4 and some clone of classic ASP (Chili!Soft ASP). Learning ASP.NET (and thus having a nice language and a nice framework) would just end up depressing me.
