hi Ryan..
I have implemented the idea of including the third page(say process.aspx) between the test.aspx and thanks.aspx.But,the Third page inclusion does help somewhat but what if user clicks browser's back button subsequently after submitting the test....?
By doing this, user redirects to the first page again, and between these subsequent clicks, the pages showing the same data again and again..

Okay,
Maybe I'm not understanding the whole scope of the problem. If you set a session on the test page and check for that session in the page_load and force a redirect if the test has been submitted, any subsequent return to that page should force the user back to the "thankyou.aspx" page. This is especially frustrating because I work for a company that writes online personality tests. So here's what I do in a nutshell with very, very simplified business logic:
notification.aspx -> answerSheet.aspx -> thankyou.aspx
What I really do is keep it all on the same page and use AJAX and custom controls, but that doesn't help you with your problem.
So here is the rundown (forgive me if there are syntax mistakes here, I'm doing this quick before a meeting):
notification.aspx - This page explains the test, sets up some user info and sets the following in page_load.
protected void Page_Load(object sender, System.EventArgs e)
{
Session[COMPLETE] = false;
}
answerSheet.aspx - This page has the radio buttons for answers. It's here that I would have the following code inside the Page_Load() method in the answersheet.aspx codebehind file:
protected void Page_Load(object sender, System.EventArgs e)
{
if (Session[COMPLETE] == null)
{
Response.Redirect("notification.aspx");
}
if (Session[COMPLETE] == true)
{
Response.Redirect("answerSheet.aspx");
}
}
thankyou.aspx - This page would have the following code:
protected void Page_Load(object sender, System.EventArgs e)
{
Session[COMPLETE] == true;
}
The following code will allow the user to go back to the answer sheet, but it won't matter because on page load, they will be redirected back to the thank you page.
I will not give up on you, brother. If this doesn't help, post the code in the page_load methods and we can go from there.

thanks for your concern Ryan.
But i have implemented another alternative for this. I have used onLoad event in the thanks.aspx in its body section as following:
.......................
.............
by doing this,the back button after reaching at thanks.aspx webpage, is disabled. It means it doesn't redirect to the test.aspx webpage again and again.
but I'll use the code you have sent this time and let you know it helps.
And if it doesn't work, then i'll give you the code of those webpages.
Thanks

Do not ever ask for the code on CodeProject. You will be treated like this ^

This code to find the MAC address of a PC connected to the internet.
What's a sName in the code?
public class GetMacAddressFromIPAddress
{
[DllImport("iphlpapi.dll", ExactSpelling=true)]
public static extern int SendARP( int DestIP, int SrcIP, [Out] byte[] pMacAddr, ref int PhyAddrLen );
public string GetMacAddress(string sName)
{
string s = string.Empty ;
System.Net.IPHostEntry Tempaddr = null;
Tempaddr = (System.Net.IPHostEntry)Dns.GetHostByName(sName);
System.Net.IPAddress[] TempAd = Tempaddr.AddressList;
string[] Ipaddr = new string[3];
foreach(IPAddress TempA in TempAd)
{
Ipaddr[1] = TempA.ToString();
byte[] ab = new byte[6];
int len = ab.Length;
int r = SendARP( (int) TempA.Address, 0, ab, ref len );
string sMAC = BitConverter.ToString( ab, 0, 6 );
Ipaddr[2] = sMAC;
s = sMAC;
}
return s;
}
}

And this case , it's the internet ip address and not the pc ip address, isn't it?
2nd thing is that, when using this code, how to suppply internet address for it, do I have to get a code to detect the internet ip address and then pass it to the MAC Function?

Hi,
Is it that IIS spawn a seperate worker process for all FTP requests, one for all HTTP requests, one for other
message based requests
or is it that there is only one worker process in totality and there can be any number of application domains no matter
whether the request is FTP, HTTP or any message based requests
Thanks,

After implementing a CSS template to my web site i am getting the following error while running. "Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. "
I searched a lot in net and found some solutions which did not worked for me. But my actual problem is the same code is working in another browser. I am getting the error while i am using IE. What is the reason and solution???
