RegEx - How To Group Multiple Email Addresses And Usernames
Aug 4, 2009
I have the following text that I am trying to parse:
"user1@emailaddy1.com" <user1@emailaddy1.com>, "Jane Doe" <jane.doe@ addyB.org>,
"joe@company.net" <joe@company.net>
I am using the following code to try and split up the string:
Dim groups As GroupCollection
Dim matches As MatchCollection
Dim regexp1 As New Regex("""(.*)"" <(.*)>")
matches = regexp1 .Matches(toNode.InnerText)
For Each match As Match In matches
groups = match.Groups
message.CompanyName = groups(1).Value
message.CompanyEmail = groups(2).Value
Next
But this regular expression is greedy and is grabbing the entire string up to the last quote after "joe@company.net". I'm having a hard time putting together an expression that will group this string into the two groups I'm looking for: Name (in the quotes) and E-Mail (in the angle brackets).

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 am trying to send email messages to multiple email addresses from a listbox. Here is my code -
For i = 0 To lstbxEmailAddress.SelectedItems.Count - 1
If EmailAddressTo = "" Then
EmailAddressTo = CType(lstbxEmailAddress.SelectedItems(i), DataRowView).Item("EmailAddress")
[Code]...
I am able to get the email addresses stored in the variable EmailAddressTo separated by a comma in between addresses. However, it only sends to the first email address. I selected two addresses but it only sent to the first address. How can I add multiple addresses using the To.Add method?

im using vb8.net im struggling to make a program that will display email addresses so in other words if im using ms outlook then by the click of the button the program must go in to the windows registry and then look in the place where the email address is and then read that part and display the address in a text box.

I am having an issue where I am using regex.Replace to replace part of a string. The basic idea is that I want to capture the beginning of the string then replace the end of the string with a value from code. For an example pretend I have a string that says "Test Number " followed by number and I want to increment that number. I capture the "Test Number " but when I try to concatenate that capture with the new number it treats the capture ($1) as a literal and replaces the entire string with $1[new number].
[code]...
This will output "We are on Test Number 2", as expected. how I can use a variable in the replacement string portion of the Regex.Replace when including a captured group?

I have created an application and I need to send emails to different addresses. I want to do this inside my application without automating email software like outlook etc. I have used CDO , and different activex like ostrosoft , chilkat etc .But is the same problem : Emails are sended correctly without error messages but :Some emails are received ( like in yahoo adresses), a lot of emails are marked as spam, and all the emails send to hotmail addresses are lost, not received. To send emails I'm using a regular domain, with smtp server, port, user name and password. And when I send emails from the same configuration on outlook express from the same computer, all the emails are received correctly.

I have a simple email.aspx page that has From:, To:, Subject:, and Body: text boxes. The send button is set to send the email using smtp through System.Net.Mail in ASP.NET 4.
What I'm really trying to do is set the To: address to automatically retrieve all of the email addresses stored in my SQL database table that my customers entered when they registered for updates from my websites, rather than me type each one in by hand. I am wanting it completely automated without any user interaction.
I have looked everywhere for weeks to try to get help and I can't seem to find anything describing what I am trying to do.

I have taken an interest in creating a SMTP server in vb.net that has the ability to hide ip addresses in email headers.I see that some people claim that it's possible around on the internet, but I haven't seen any direct source code to create an anonymous smtp server in visual basic 2008.Now I know that it's legal to send emails via a masked ip address and I believe that it's also fair since some people believe in anonymity, but I am in all means against spammers.

We have a VB.NET application that is using the TAPI3Lib.dll. At this one site we can multiple addresses for the same Phone extension. For example for extension 149 we are getting Extension 149 - Address # where # is 0 thru 208. Is there a way to just get "Extension 149"? Have downloaded some free utilities and they only show "Extension 149".Below is the same of code:

I want to be able to specify multiple smtp server host addresses and implement a logic whereby if email using one smtp server fails, it tries to send using the next smtp server address.

I'm trying to find a way where i can make it loop through the results of my capture group regex query.
For instance if i have this:
VB.NET
Dim matches = Regex.Matches("<h1><span>test</span></h1>", "(?<=<h1>(<span>)?)(?<data>.+)(?=(</span>)?</h1>)")For Each item In matches.OfType(Of Match)()Console.WriteLine(item.Value)Next
And i'm trying to get the contents of <data>, how do i do it without it printing out the junk before it and after it?
quantifier isn't working, its supposed to make the <span> tag optional in the query, but it isn't.

I have a vb.net 2008 form that sends and email along with an attachment.
I want to offer up a list of available email address to choose so my user doesn't make a typo.
Problem is the email addresses are not part of any GAL / group because they are from outside the company. However if my user begins to type the email address such as xyz outlook begins to make suggestions such as [email]xyz@anothercompany.com[/email]; [email]xyz@noinagroup.com[/email] because my user has either sent them an email in the past or recieved one. Or if the user types a name outlook will suggest. Jon Doe Jon D. Doe
My question, where does outlook keep this list and how can I retreive it using vb. I know how to get the Global Address book and the other contacts but I need the list of emails that are not associated with any groups but are in outlook.

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)

I 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 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?

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?
