C# - Checking If Email Address Already Exists In Db?

Feb 28, 2011

I'm trying to error handle a registration aspx/c# page on my application and want to run a check whether the email address that a user has tried to register already exists as the email address is used as a primary key in my database.

I have tried IF NOT EXISTS/IF EXISTS but these dont give the desired effect so was wondering if there was another way around it?

Web Forms :: Check Whether Email Address Exists Without Email Confirmation

May 7, 2015

In addition to the process of regex syntax validation of Email Addresses entered by users, I'm trying to check if the entered email address is a real one and does exist?The best I could achieve is to "Ping" the host the email address is associated with. But there are some other terms in the industry like Handshaking with Email Server, etc.not necessarily with 100% confirmation accurary!

How can I check if an email address actually exists?

Web Forms :: Checking Unique Email Address Against Database Record In Edit Case?

Mar 1, 2010

I am using a form to add and edit record of database.

In Add case my email box has no value. I have used customservervalidation to check the given email address with previous database records.

In Edit case my email box is populated with data from database.

When i click save button in both cases my customservervalidation method invokes and checks the given value. it works fine for new/add case but in edit case it checks with itself also and says duplicate email... pointing own record...

C# - Checking If A Remote File Exists?

Mar 24, 2011

I have a ASP.Net website with links to files stored on a file server. These files are modified constantly and so the links will not always be valid, this includes changes to permissions, files being moved or deleted, etc. I implemented a method in the code-behind to check the validity of these links as they are constructed, if it fails the code will add CSS to change the color of link:

Check URL

/// <summary>
/// Check if a URL exists. Method by http://www.vcskicks.com/check-website.php
/// </summary>
/// <param name="url">URL to validate</param>
/// <returns>True if the URL was resolved, false otherwise</returns>

[Code]....

My problem is that not all the invalid links are getting the style added to them. The strange thing is that when I step through the method in debug mode using one of the bad links that was not colored, the method will return false and color the link as expected. There's a lot more involved then what I present above, but I searched the entire aspx code-behind for any other locations where the link url is being set and couldn't find any. I don't know if there's some post processing going on that somehow clears any styles that were applied to some of the links. The fact that some links are colored while others are not is very confusing to me. Has anyone else encountered similar behavior before?

C# - Checking If An Item Exists Before Saving?

Feb 2, 2011

I've a SQL DB with various tables that save info about a product (it's for an online shop) and I'm coding in C#. There are options associated with a given product and as mentioned the info recorded about these options is spread across a few tables when saved.Now when I come to edit this product in the CMS I see a list of the existing product options and I can add to that list or delete from it, as you'd expect. When I save the product I need to check if the record already exists and if so update it, if not then save a new record. I'm trying to find an efficient way of doing this. It's very important that I maintain the ID's associated with the product options so clearing them all out each time and re-saving them isn't viable unfortunately.To describe again, possibly more clearly: Imagine I have a collection of options when I load the product, this is loaded into memory and added to / deleted from depending on what the user chooses. When they click 'Save' I need to check what options are updates and what ones are new to the list.

C# - Verify That Email Domain Exists?

Jun 14, 2010

Does anyone check the domain of an email address as part of their verification steps? eg. Confirm that gmail.com exists if the user specified blah@gmail.com as their address.

I should note that in my webapp an existing user can forward invites to their friends. I have no need to verify those invites at all. Rather, I just want to warn my user if a typo etc. may be sending an invite to the wrong person. Is this even worthwhile to do?

SQL Server :: Stored Procedure For Checking Db Values N Then Sending Email Periodically

Dec 16, 2010

I have a .net 3.5 application in c# with sql server 2008 at back end. The application is about assigning jobs to supervisors and then these supervisors have to write remarks about the job progress from time to time. There are two tables ; a JobAssign table with JobOrderNo and Supervisor columns, and a JobUpdate table with jobOrderNo,Date And Remarks(nvarchar) column.

When a supervisor is assinged a job he is sent an email but sometimes the supervisors do not write remarks about a job for some time. i want a stored procedure through which if the remarks of a job are not written for say 5 days an email is sent to the supervisor to do so? in my job update table there are multiple entries for a job so the stored procedure will have to check the Top Remarks Date for each jobOrderNo. then compare it to today date if the difference is difference is 5 days then send email. i have read posts on sending email through job scheduler but i'm new to stored procedure so have no idea how to write such.
