We are developing an Intranet application that looks up some data for a user through hooks into Active Directory. However, our Network guys don't always enter in a users email address when creating a new user. Therefore, our user database is missing the email address for over half of our users. We have over 10,000 users, therefore asking them to enter 5000+ email addresses into each missing email address field in Active Directory isn't an option. I already know how to validate that an email address is correctly formatted using Regex. What I need is a way to lookup the email address entered in the email address textbox and see if it exists on Outlook/Exchange (or looking up the email address using the First Name/LastName would work). If it does exist then the address is valid, if it is invalid then the user typed in the wrong address. I've tried to do something with CDO, but have had no luck. We use Outlook 2003 and ASP.NET 2.0.
multiple email address are enetered in the textbox at present i have used SPLIT function to split the emails based on a delimiter on server side wht i need is , suppose i have 10 email addrees in the textbox and suppose 3rd one is not valid i dont want the processing to be stopped at 3rd , if 3rd is invalid it shld be skipped and the 4th one shld be processed.
When validating an email address with the regex validation component, an additional RequiredFieldValidator must be added to ensure there is a value present.
I've mostly taken care of this with a CustomFieldValidator, and taking care of this with Javascript.
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!
here is sender email but i want there wasn't any email address.I mean i want when users click on button and send me an email there wasn't any email address in sender details.
I am building an email feature in my website (jobs site). By using this functionality, recruiters will be able to send emails to candidates. I want an option so that the user can also set 'From Address' and the email should be ANTI-SPAM compliant.
How me can validate a email textbox to take only valid email address if error occur it show the error message in this textbox or as a tooltip. because in the form there is no space to show error message.
I am writing a registration form which will store all the information to the database. I need to validate some data before saving like empty and isunique.
I have username and email address field in my form. I used CustomValidator to call a function check unique to execute my code to check the given email address with the list in database.
It works fine for new case but when i am for edit case it does check with itself and reports already in use.
My Steps:
1.) Page load
If edit case retrieve data and populate them in control like. txtemail.text = dbrec("email")
