i have tried various ways to accomplish this, but to no avail. I don't know how to generate the replacement text (mailto link) so I just used a bunch of x's until I can figure it out. Here is what I have (which currently not replacing emails in string): Here is my Code behind:

I am using this regex string in one of my programs to validate email adresses: "^[a-z0-9._%+-]+@[a-z0-9.-]+.[a-z]{2,4}$". This works well for the most part, but I just found out that it doesn't catch an address like this ... "john.doe.@yahoo.com" ... where there's a "." right before the "@", which is invalid, so my program tries to send it & throws an exception. How to modify my regex string to catch this situation?
View 4 RepliesI have been using a function to validate email addresses for awhile now. Yesterday i discovered that the code indicates that 2 different email addresses are invalid when in reality they are perfectly fine.
The code uses RegEx to determine if an email address is valid. I have tried to understand RegEx, but I can never seem to figure it out. Here is the
Private Sub btnCheckEmail_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCheckEmail.Click
If ValidateEmailAddress(txtEmail.Text) = True Then
[Code]....
How can the RegEx be re-written to allow the local part (before the @ symbol) to be 1 character, and/or be a number? I understand the "a-z" part, but i don't understand what [w.-] means, or why the a-z is duplicated before the @ symbol.
I am using this expression to validate e-mail addresses:
"^[_a-z0-9-]+(.[a-z0-9-]+)@[a-z0-9-]+(.[a-z0-9-]+)*(.[a-z]{2,4})$"
I noticed that in order for the e-mail address to validate, I need to put in at least 3 characters before the @ symbol. Is this a requirement? What if I just want to have an e-mail address with 1 or 2 characters before the @ symbol?
My Regex works, except if the email address entered has an underscore character (_) in it.
Because of my lack of experience with regular expressions, I'm not sure where in my pattern I'm supposed to add the offending character to allow it:
Dim pattern As String = "^[-a-zAZ0-9][-.a-zA-Z0-9]*@[-.a-zA-Z0-0]+(.[-.a-zA-Z0-0+)*." & _
"(com|edu|info|gov|int|mil|net|org|biz|name|museum|coop|aero|pro|tv|[a-zA-Z]{2})$"
He said he fixed it by adding the _ after the numeric check.
I see the A-Z0-9, but I'm not sure which is the numeric check...
Scenario: We are using a createwizard control to create users for our website. When the user has an email we simply send the user the email with their username and password saying their account has been created. Using MailMessage and SMTPClient.
Problem: When the user doesn't have an email (ex. temp employee, student) I need to be able to generate the email but have it open via the creator's mail client so that they can enter in an email themselves/see the username and password. Similar to @mailto functionality. Question: Is there a way to do this from the code behind? I have tried searching but everywhere is telling me to use MailMessage and SMTPClient which I don't need.
In member register page, I added email address validation but it only check the email address format, such as .com, .net, .org.If user inputs fake account such as aaabbb01010@gmail.com, how to verify it and return an error?
View 2 RepliesThe following is my function. The error occurs when I try and set the from email address. It gives me an error: "The specified string is not in the form required for an e-mail address." But the email address is in a perfectly legitimate format (I changed the email so I don't get killed with web-crawlers pulling addresses, but it is the exact same format). Hope someone can see what I am obviously missing.

I work for a printshop that screenprints customized hats ,tees and a host of other stuff for a variety of small businesses. Being that we are a small business as well, we can't afford to mass ship catalogs to our clients, so I decided to build a catalog application/business card that can be emailed to them. The app is rep. specific, and after choosing which options suit them best using text fields and combo boxes, upon clicking submit, the customers' info is emailed to the rep.
To do this, I am trying to get a popup window that displays an email form with the 'mailto' address previously set, so it can't be altered and the info from the previous screen to be pasted in the body of the email. Upon clicking the confirm button, the mail is sent and the window is closed. I already have the code to copy the info from the textbox and combobox entries and paste it into the textbox in the next form, but getting the email form to be functional is appearing to be quite a feet.
A client for our company contains an apostrophe in their email name joe's@joe.com. I was advised that this is the correct and current email for the given client. Below is the Expression string I am using with Regex (which I copied from the internet somewhere) to validate email addresses. How can this expression be modified to allow/accept apostrohe's?
strRegex =
"^([a-zA-Z0-9_-.]+)@(([[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.)|(([a-zA-Z0-9-]+.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(]?)$"
I have to make a basic program that: Create a program with a simple interface that
1. Asks the user type his/her email address into a textbox.
2. When the user clicks the "Evaluate Email Address" button, one of two message boxes pops up: "That is a valid email address!" with an "Information" icon, or "That is an invalid email address!" and on a second line, "Please retype your email address.", with an "Exclamation" icon
3. To be considered valid, the email address must -include an "@" symbol, and -it must end in either ".com", ".net", or ".org" or ".edu" (I don't know how to check a string and test if its last four characters end with any of these and make it say not valid email address. I think I might have to use a case statement)
I have the following column values in my table Sample values:
[URL]
I want to have 2 variables having the links and content separate - example:

I guess it can be done via String functions or regular expression.

What I would like to do is create a command button that launches an email from outlook attaching the current word document to a set email address. I'm not fussed if the word document is saved or not as it is only the email receipent that needs it, likewise I don't mind if the code instructs the email to send of just opens it ready to be sent.I have read through loads of forums and tried loads of codes but cannot get any to work.

Outlook is causing some problems when being passed a mailto string with accented characters in it. Changing the codepage for my entire webpage that has this string on it solves this problem, but that causes other problems in the system, so I would not like to do that.
A string like such returns a lot of garbage characters:
"mailto:Helpdesk-someemail@email.com?subject=Mon bâtiment / Départementé / Bureau n'est pas répertorié"
Meanwhile, this cuts off the character after the "D"
"mailto:someemail@email.com?subject=Mon bâtiment / Départementé / Bureau n'est pas répertorié"

i can use Regex matching to find urls in text, html source.But can Regex be used to get the link text (whats shown on screen) for that url it found e.g

I hired a coder to code me something in Regex. The issue was that he coded it in Visual Basic and I need it in C#. I tried using a converter but it didnt fix the issue.
string iamtwit = ss("http://www.mailinator.com" + GetBetween(GetBetween(iamtwit1, matches.ToString(), "</a>"), "<a href=", ">"));MessageBox.Show(GetBetween(matches1.ToString(), "<a href="", Strings.Chr(34)));
Here is the original code:
Dim iamtwit As String = ss("http://www.mailinator.com" & GetBetween(GetBetween(iamtwit1, matches.ToString, "</a>"), "<a href=", ">"))
MsgBox(GetBetween(matches1.ToString, "<a href=""", Chr(34)))

The name 'GetBetween' does not exist in the current context
The name 'Strings' does not exist in the current context

I've tried implementing a rather simple email validation function that seems return a false match even though the input is a valid email. I have searched for any issues with the existing regex but it seems to be correct.Even though the match returns a false value the program is stepping to the next validation level (which it shouldn't).Here is the email validation function.
Function EmailAddressChecker(ByVal emailAddress As String) As Boolean
Dim regExPattern As String = "^[A-Z0-9._%+-]+@[A-Z0-9.-]+.[A-Z]{2,4}$"
Dim emailAddressMatch As Match = Regex.Match(emailAddress, regExPattern)
