Object reference not set to an instance of an object

I call a function on my development server and it works, but when I deploy it on live it does not find it and gives the above error! I can't think why, when I empty the function to do nothing at all just exist, it still fails.

So its not the contents that are causing this, just the fact that the function cannot be found. Almost as if the new dll is not being used.

Any help greatly accepted.

RichardPlease check if you had placed the dll's in the correct folders or not
Thanks,

Only one dll, and it goes in the bin directory, any other ideas?

Object reference not set to an instance of an object.

Hi,
I've developed my first ASP.NET application using VS2005, when I run it from the IDE it works fine but after I deploy it under IIS, it no longer works.

It gives me this error

Object reference not set to an instance of an object.

The code to the page that I call looks like:

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

public partial class Login : System.Web.UI.Page
{

protected void Page_Load(object sender, EventArgs e)
{
string fName = "";
string tCode = "";
string sBox = "";


fName = Request.QueryString[1];
tCode = Request.QueryString[0];
sBox = Request.QueryString[2];

string path = "xxxxxxx";

string link = "<a href=\"" + path + sBox + "/";

Session.Add("link", link);
Session.Add("tCode", tCode);

}

}

When I call the page I do pass the parameters in the url?

Thanx in advance

When things seem to work in the built in web server of VS2005 and not in IIS, the problem usually is security in my experience....

Seems like your applications is not configured as an IIS application. Try to create a virtual directory pointing the path of the project and access again~

Thanks
Is there anything(security related) specific I need to configure to make my application work under IIS?
