How should email address opt-in implemented? -


Scenario:

The user gives you an email address before signing up for the services, Email address must be validated - You email, click on the URL, then they can subscribe to the services.

Question:

What does the URL look like? I'm thinking that a random guide would be fine.

Do you use the same random key to cancel requests?

Is anyone looking for double-opt-in to implementing a good open source?

I have used random GUID before such objectives to verify an email account, And it works well until you're working with ultra-safe, ultra-sensitive data, then it should be enough. I do not see the reason for using a single GUID for no request - in this way you need to store a GUID in an account that your Subscriber database (or you can store them). You can add unsubscribed links at the bottom of all e-mails, which can make this a simple one-click option.

I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
