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.
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.
View 4 Replies how to check the domain name of an email address...
i.e
in 4@4.com
validating 4(second one-domain) should return false if the domain is not exist again
if 4(first one) is not a valid user then also return false
My company has two different domains for there email
1. [URL]
2. [URL]
i need to validate a text box which captures email address and make sure that it only allows these domains so [URL] and [URL] is allowed.
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.
View 10 Repliesi have an requirment where an user can enter multiple email address.
The validation should ensure that he should enter address in the format "something@abc.com".
my existing validation ensures that some text is entered before "@" symbol and "abc.com" is the domain.
@"w+([-+.']w+)*@abc.com$";
I would need my regex to check for the delimiter ";" between two mail id's .
valid: a@abc.com |
a@abc.com;b@abc.com|
invalid: a@abc.comm | a@abc.com,b@abc.com | @abc.com |
a@abc.comb@abc.com|
I've tried many links but ther were of no use and i'd be grateful if someone could help me modify the current one to suit my requirments
how do I grab an email address from a web form and email to that email address with the link to a webform?
View 5 RepliesI'm using the Asp.net change password control in my application and all seems to be find and dandy until a user tells me she has a problem meeting the strength requirements when changing her password. Looking into this, she is using IE 7 and no matter what she puts in, the validation fails (and ONLY in IE 7. Firefox, IE 8, Chrome etc. all work as expected). Here is the regex i'm using:
^(?=.*d)(?=.*[a-z])(?=.*[A-Z])(?!.*s).{5,15}$
I've tried out a few others that I've found throughout this site and others that folks seem to be using with no issues and I come across the same problem.It seems that which ever pattern I enter in last (digit, upper or lower alpha) is the one that is expected to be repeated min of 5 times. For example:
Hello1 (doesn't work)
11111Hello (doesn't work)
Hello11111 (works)
Again, this is ONLY in IE 7.

View 1 RepliesIn 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!

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")
2.) submit action
if page.isvalid() then
end if

View 2 Repliesi have a database query getting the email address of the user how can i put the email address of a user and code it here...
source code:
MailMessage msg = new MailMessage("usermail@abc.com", "#####@#####.com", "Mail Subject", "Mail Message");
I have this simple regex string to validate emails. It worked fine until someone came along with an email address that contained an ampersand:
^(['_a-zA-Z0-9-]+)(.['_a-zA-Z0-9-]+)*@([a-zA-Z0-9-]+)(.[a-zA-Z0-9-]+)*(.[a-zA-Z]{2,5})$
how I can alter this to accept the & symbol? I have tried countless ways with no success.
I want to find a substring (email) in a large text using Regex.
just want to return the first valid email that is found from the input text:
example:
string inputString = "Our email is myname@ourcompany.com.
desired output: myname@ourcompany.com
this is the Regex pattern i've used: ^[A-Z0-9._%+-]+@[A-Z0-9.-]+.[A-Z]{2,4}$
- is this pattern correct?
Code:
private static void DumpHRefs(string inputString)
{
Match m;
string HRefPattern = @"^[A-Z0-9._%+-]+@[A-Z0-9.-]+.[A-Z]{2,4}$";
m = Regex.Match(inputString, HRefPattern,
RegexOptions.IgnoreCase | RegexOptions.Compiled);
while (m.Success)
{
Console.WriteLine("Found email " + m.Groups[1] + " at ".......
This is probably a simple one for C# people :-) I have this regular expression in javascript:
strVar = strVar.replace(/(specificattribute=)"s*([^"]+?)s*"/g, '$1"$2"');
It replaces leading and trailing spaces inside a specific attribute's value, globally (as per this example page: [URL]). I need to do the same on a string in C#, but when trying the above, the syntax checker chokes at the regExp. So I need the equivalent line of the above in C#.
In my resiter form i want users to restrict them not to enter gmail yahoo ids, only company ids would be accepted..
View 1 RepliesI have a longer text and some keywords. I want to highlight these keywords in my text. That is no problem with this code:
private static string HighlightKeywords2(string keywords, string text)
{
// Swap out the ,<space> for pipes and add the braces
Regex r = new Regex(@", ?");
keywords = "(" + r.Replace(keywords, @"|") + ")";
// Get ready to replace the keywords
r = new Regex(keywords, RegexOptions.Singleline | RegexOptions.IgnoreCase);
// Do the replace
return r.Replace(text, new MatchEvaluator(MatchEval2));
}
private static string MatchEval2(Match match)
{
if (match.Groups[1].Success)
{
return "<b>" + match.ToString() + "</b>";
}
return ""; //no match
}
But when the word"tournament" is in the text and the keyword "tour" it becomes <b>tour</b>nament. I want to it to highlight the complete word: <b>tournament</b>.
