Activation Link That User Will Press To Activate An Account

Nov 26, 2010

Doing an activation link that the user will press to activate an account. What i wanted to ask is, the link will go to a page and it will hit the sql server to find out if it's valid.Now what i'm afraid of is that some boot can send thousands of get's in the page, forcing the sql to be active with useless data. So is there a way to protect against this? I was thinking the "lock ip" trick i did to stop users trying to log in to a site many times. Any other suggestions are welcome. Some other think also.I use a try catch in case of a get with not or wrong data.Will this affect the site in general? I mean i don't really care if someone post an invalid get and wait for the try catch, but does this affect the performance of the site in general or a session takes the memory by default and ignore any try catching that s stalling the page.

Web Forms :: How To Send User Confirmation Email After Registration With Activation Link

Jan 21, 2010

I want to send a confirmation email to the user after they register to my website. I am using CreateUserWizard of .NET and I use C#.

My idea is after users register they get an email with a link. If they click the link, they will come to an activation page. I have done this so far:




After Guid userId = (Guid)user.ProviderUserKey;

I am very confused and not sure what to do. I understand that i need to email an url with the userID to user's email upon registration, but how to do this, and when user clicks that url in that email, how that url will automatically come to activation page?

Email Newly Registered Users An Activation Email With An Activation Link

May 16, 2010

I've been programming with VB for a little over 2 years, however have never had any formal education. So the extent of my education is as follows:

I want to know how to do a mouseover for an image on my webpage, I look online for someone who's done it in VB and I try and duplicate their code and then play with it until I get the results I want.

So as you can see there is a wealth of VB coding that simply escapes me because I just haven't desired to include it or needed to include different aspects of VB in my programs / web developments. What I want now is big enough that so far (one week of online searches) I've uncovered no site or forum that has given me a tutorial on how to go about implementing what I want into my Microsoft Web Development project. The old sources for information are only good for one or two aspects of a coding procedure, not an entire overhaul of my current .aspx files. Not to mention a bias towards hard coding in pure <html>, I get a lot of that when someone doesn't have the patients to address my question.

When I created my new project it automatically populated an Accounts folder with a Changepassword.aspx, Changepasswordsuccess.aspx, registration.aspx, and Login.aspx. I've successfully prevent the program from logging in the user after they register with a simple " ' " before an authentication line in the registration.vb code; however, the login.vb code and the code is simple beyond me, and I've yet to find a site that spells it out for me.

I've created an online test. However, the intent is to have the users only take the test once, thus after they register with their email address I want my site to send them an email with an account activation link. Once they click on this link by visiting their inbox they can then take the test.

C# - Validate User Account Via Email Link?

Jun 21, 2010

Really sorry because this is almost "send me the code" - although really it's "send me a link to another discussion"

I am setting up a .net membership system and need to validate users from the email address they provide via a "click here to validate your account" type link.

Just wondered if anyone knew of any good tutorials or posts out there about this? I have searched for about an hour and can't find anything - hence me asking the question.

Security :: Activating New Account After New User Clicks Link In Email?

Jun 30, 2010

Could anyone provide guidance about the common technique of sending an email to the new user -> new user clicks the link in the email -> and then the account becomes activated and ready for use?

Currently using the CreateUserWizard control in .NET v4 and a Membership db in SQL Server 2008. If I need to do this via custom code and not the CreateUserWizard that's fine. Would be nice to see expert thoughts on this common, enterprise quality, new account validation technique.

The link below outlines a technique for sending a confirmation email but does not include activation:[URL]

Web Forms :: Activate ChecKBox Validation When Clicking Button In Created User Wizard Control?

Oct 26, 2010

I have a checkbox on my page that must be ticked and to validate it I am using a custom method as below. The problem is that I now put the checkbox and method within a Create User Wizard custom tempalte and when I submit the form it does not activate the validation check. If I put a normal button on the page outside the tempalte it works. Not sure If I a missing something. Perhaps I can activate it in Created User Event handler in code behind. All Button in my create user Event.

<asp:CheckBox ID="Terms" runat="server" />
<asp:CustomValidator ID="valTandCs" ClientValidationFunction="ValidateTandCs" runat="server" ErrorMessage="Please accept Terms and Conditions before submitting."></asp:CustomValidator>
