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.
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.
I'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:
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.
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 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.
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 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")
I want to validate complete Email address. I am not asking to match using pericular string. but suppose someone enter email id a@bnm.com then first the bnm should be validated and if such domain found then also it should check for such a@bnm.com is available or invalid.???
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#.
I 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>.
