Anyone got a link to a good tutorial which shows how to create a read-only text-box in a Web Application which automatically collects a visitor's IP Address?

Thanks

It's in the Request object ( the IP address ). Use a label, that's read only.

Here you go...

txtbox.Text = Request.ServerVariables["REMOTE_HOST"];
txtbox.Attribures.Add("readonly", "readonly");

public static string GetLocalAddress()
    {
        IPAddress[] addressLocal = Dns.GetHostByName(Dns.GetHostName()).AddressList;
        if (addressLocal.Length > 0)
        {
            return addressLocal[addressLocal.Length - 1].ToString();
        }
        return "127.0.0.1";

This would always give the server address.

I am building a website, and want to clear cache of all the clients from server at a particular time. Please let me know how to do this. Blush | :O

Have you tried

Response.Cache.SetNoStore();

when one visits your page ?
Big Grin | :-D

Also add these

Response.ExpiresAbsolute=DateTime.Now.AddDays(-1d);
Response.Expires =-1500;
Response.CacheControl = "no-cache";

Hope this will help.

skip validation

hello -
there is a shopping cart issue what I am working on right now. I am adding a back button, but for posting back to the server, the required fields need to be validated. Is there a way how I can skip the validation for the back button?
Thanks, Laziale

I think dont rely heavily on back button.
Rather always handle everything using code.

Please let us know how you are validating your page Confused | :confused:

, so that I can tell you how to handle this.

No, there is not.
The only issue I can see is that you have not deployed your application properly. D'Oh! | :doh:

Does it gives you any error. Please specify... so that I can help you with whats wrong.

Actually the Crystal report is processed inside the viewer and passes an html to the browser. Check what it is rendered... Big Grin | :-D

It happens when you mix 32bit and 64bit web farms.

The reason is that the page requests a javascript using the hashcode present in the page which is generated using GetHashCode the value of which is different in 32 and 64bit machines.

The hashcode 865923e8 might be generated from one server and the request of the combined javascript might be placed on another server.

Hope you got the issue. Smile | :)

ASP.Net has to do nothing with this.
You will have to think of executing a process/script, which will basically run a SQL query on the database and change the status of the demands which have been older than 72 hours in the system.

Did you read my reply? I already told you a way to do this.
If you are expecting the code, than excuse me as I have no idea of your database structure.
