Public Rating Script Allowing 1 Submission Per Visitor?
Aug 8, 2010
I've written a .NET/jQuery rating script that allows users to rate a particular product.
Everyone that visits the website can rate, but I'd like to only allow 1 rating per visitor.
So far I've considered the following options.
1: Store the users IP address and only allow 1 submission per IP.
this would mean that people on corporate LAN's, Internet cafe's, public Wi-Fi's and such won't be able to vote after someone else has from the same location.
2: After voting, create a cookie in their browser that indicates they've voted.
This isn't a good solution either, since people using Private Browsing will be able to vote as many times as they like, OR a more advanced user will clear their cookies and keep submitting a vote over and over again.
I have a rating control that shows the average rating of a user supplied posting (think of a forum post that others will rate). So if the average rating for that posting is lets say 3 out of 5 all users will see 3 stars. If someone wants to rate the posting, then they could click lets say 4 stars and I save the rating to the database, re-average the current rating and display the result (which may or may not still be 3 at this point). So far so good. The problem comes in when a user wants to agree that it's 3 stars. Since the rating control currently shows 3 stars, choosing 3 again does not cause a postback. In my case even though the value didnt technically change, I need to capture the users choice so I can average it in and save that users rating. I also modify the UI so that I can show each user of the site what he/she choose as a rating.How can i get the control to let me know that a user choose a star rating even if its the same one the control is currently displaying?
I was able to find examples throughout the internet that more or less accomplished what I needed to be done, but now I have run into some problems. I need to be emailed the form data when the users submits it and then the user needs to be redirected to a thank you page, in this case "thanks.asp". I have been unable to get the form to redirect users to the thanks page, and in my efforts I think I might have messed the email process up as well.
This is fetching the IP address alright, but now I want to know the country of the visitor and USE that country name to redirect the visitor to some webpage accordingly.
I came across this library but have no clue how to use it in the project. Actually I do, but I am not sure so I am asking.
http://ipaddressextensions.codeplex.com/
When I download from the above the ZIP folder has a DLL file and an XML file. Now, what do I do with these two? Like include in the project. Then what do I type in the code file?
Something like the following.
if (countryName=="France") { response.redirect("www.mysite.fr") [code]....
How do I go about it? Also do I really need to type SO many if blocks for ALL the countries. How do I shorten this code?
I am using AJAX Rating Control.I want half star rating.For Example,If My AVG Rating Count is 3 Then My Stars Wants to be show 3If My AVG Rating Count is 2.5 Then My Stars Wants to be Show 2 1/2 mark i.e., two & half stars.But,it was not showing then also it is showing 3 stars.
i have a form which has two textboxes and a submit button.on entering data and submitting data gets stored in the database.but if i again refresh the page the same data again gets stored.How should this be prevented?
I have a question about C Sharp ASP.NET:Is there a difference (in code speed, resources) between:public static variable declared in public static class MyGlobals in a 'Code File' template;and the variable declared in a normal 'Class File' template;I use this variable in 2 different Class Files and also in _Default Page codebehind cs file.In fact in my case I need about 20 global variables of type List<string>.
in PHP, I can know these info for the visitor: IP Address. IP HostName. Natted IP Address. Natted IP HostName. User-Agent (Web Browser, OS version, framework, infopath, etc...) Web REQUEST. Web Referrer. Language. DateTime. How can I know that in asp.net? And what additional info can I know using asp.net? And how can I know if the visitor have special software installed?
I'm trying to write an application that allows a visitor to use our service for 7 days. After 7 days, they will no longer be able to use it unless they sign up. What's the best way and the most accurate way to track it without collecting their credit card information? I'm trying to use the following code to track visiotr's ip. But I'm not sure if people are able to change their ip address or using a proxy server that will go through.
I created my own register system with my own register form together with the asp.net login control
the user register and the data is sent to my custom table and I used a method that check if the user exists in my table and the asp.net login control display the correct result "if exists or not"
everything appears to work correctly but I cannot access pages that deny anonymous users with the configuration file.
We are having two load balancing server. In that we have hosted a asp.net 3.5 application right now we are using request userhostaddress to get visitor ip but it is giving load balancer ip instead of real ip.
I'm facing with an old problem that it made me confuse very much. So I need your advice to make sure that I've been using the right way. My demand is to count the number of visitor in my website, so I've coded in Global.asax file:
[Code]....
Then, I used variable Application["SiteHitCounter"] and Application[CurrentUsers"] in another C# behind code file to show them on web page.The problem I'm facing is that the website can't show right total visitor number as in my database when I publish it to shared host.
I am creating a site that will host my virtual resume and would like to set it up so the visitor would enter a simple code to advance past the default page. I am not looking to create a unique login for each visitor, I just want to control who sees the information online. I have used the web controls in visual studio express for for creating logins on other sites, which included additional support code like "User.Identity.IsAuthenticated == false" to redirect visitors on other sites but I am looking to see if there is a more simple way of handling this.
