C# code not working with ASP.NET

socoolbrewster · August 23rd, 2003, 05:31 PM

I have just purchased Beginning ASP.NET 1.0 with C# by Wrox Press. And have fallen at the first hurdle, which is I can't get the test program to work. I have made sure it's saved as .aspx file yet all it does is display the HTML and on viewing the page source in the browser I can still see the script itself.

The code I was required to type word for word was as follows:

<script language="c#" runat="server">

void Page_Load()
{
time.text=DateTime.Now.Hour.ToString() + ":" +
DateTime.Now.Minute.ToString() + ":" +
DateTime.Now.Second.ToString();
}

<html>
<head><title>The Punctual Web Server</title></head>
<body>
<h1>Welcome</h1>
In WebServerLand the time is currently:
<asp:label id="time" runat="server" />
</body>
</html>

Being new to ASP.NET this code seems wrong as shouldn't any ASP code still be embedded using <% and %> and shouldn't all ASP.NET pages have the following header:

<%@Page Language"C#" runat="server">

I have .NET frame work and am running the scripts on my own machine but it just does work ! I have tried a script using VB.NET and classic ASP and that works fine. Any ideas ? is the code presented in book correct? am I doing something wrong?

I am using MS Windows XP Professional and have IIS 5.1 installed and have tested scripts on my machine using a localhost

Dear new friend:
First welcome to ASP.NET & I wish u good lock!
Then u have some mistakes as:
1- Didnt closed <script> tag -> </script>
2- Text Attribute of Label first "T" is Capital.

feel free to ask ur question in forum;)

Always:),

Firstly the missing script tag was an error on my part. That should of been there already, that was just a paste error on my part.

I have made the adjustments as recommended but it still doesn't work. On running the code all it does is display the HTML code and no time!

On running the code if I view source in the browser all the source(including the ASP.net/c#) is available to see in the browser!

Maybe I have overlooked something in the setup of LOCALHOST etc on my PC? As mentioned earlier a ASP.NET script with VB.NET works fine!

<script language="C#" runat="server">

void Page_Load()
{
  time.Text=DateTime.Now.Hour.ToString() + ":" +
        DateTime.Now.Minute.ToString() + ":" +
        DateTime.Now.Second.ToString();
}
</script>

<html>
<head><title>The Punctual Web Server</title></head>
<body>
<h1>Welcome</h1>
In WebServerLand the time is currently:
<asp:label id="time" runat="server" />
</body>
</html>

I have even download the source code for each chapter of the book and attempted to run that version and it's the same as mine and doesnt work either!!! any ideas peeps!! I am so close to go back to classic ASP :-(

Hi Gaz,

The way you have your page now, it should run fine. So the error must be caused by your setup.

In what order did you install IIS and the .NET Framework? IIS should be installed first, so the .NET Framework can set up IIS to handle .aspx pages correctly.

Take a look at this page to see how you can fix it (use regiis.exe).

The way the code is embedded in the page with <script> tags is the way it's supposed to be. You'll see <% and %> mainly used for the Page Directive and for databinding expressions.

The page could indeed have a Page Directive like this:

<%@ Page language="C#" %>

However, it is not required. The Page Directive is used to set all kinds of options that apply to the whole page like Src, CodeBehind etc. Take a look at this MSDN page for more info.

HtH,

Imar

Silly silly me. I think I know what I have done wrong! A few months back I obtained a trial verison of VISUAL STUDIO .NET from work. I basically installed the .NET framework as part of that setup and IIS was already installed. However, I recall that I uninstalled IIS for some reason and installed it back on my PC with .NET framework on it.

So I have decide to start a fresh and have have uninstalled the lot and am going to do the installation in the order both you and the Microsoft web site suggest !!!

Wish me luck!!

It works !! and what is the lesson learned: well it's never guess or skip a chapter and always follow setup instructions to the T
