I'm allowing users to manage a distribution list stored in a database. Users are only allowed to enter emails that are @mydomain.com. A web based application then takes the distribution list and sends emails. I'd like to validate that the email is valid before sending an email from the application.
To send an email I'm using this code:
Dim SendTo As String = "ThisIsNotARealEmailAddress@mydomain.com"
Dim SentFrom As String = "me@mydomain.com"
Dim MessageBody As String = "blah blah blah"
[Code]....
Is there anyway to validate the email when the email address is added to the database, instead of a try catch block when sending the email?
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 use this code to send an email through gmail account but the thing I want to do is, I want to check whether the given email and password exists or not and if it exists then pop out a text box with the body of the mail and type the text and then send it as a mail. But in the above code you have to log in and type body and when you send the mail , It verifies for the email and password while sending and if anything goes wrong says there is no such gmail account.but i want to check it whether the email and password exists or not, when the user enters the email and password at the beginning itself.So that he enters the right email to log on to compose a mail.Is there any way to check whether the given email and password is correct at the beginning only ?
I'm using asp.net with vb.net..I need to send an email to my website visitor after they signup to db ..I need to do any action after inserting record to SQL db.Example

On my website I have user records. For the user records page I have three options you can do with each user record. Delete, Update and Email are my checkboxs's that I am trying to use.
<Input Type=CheckBox Name=Delete OnClick="False" Value=<=rs("num")%>><br>
<Input Type=CheckBox Name=Update OnClick="False" Value=<%=rs("num")%>><br>
<Input Type=CheckBox Name=Email OnClick="False" Value=<%=rs("num")%>>
What I want to be able to do with these check box's is when one of these slections are made, I want to be able to pass the value of the selected checkbox by pressing a button over to another page where I have a IF statement. Then value of the selected checkbox runs though the IF statement and matchs with the option in the IF statement.
[Code]...
So I guess what I am looking for is how do I get the value of the checkbox to pass over to another page and run through my IF to match with an option in my IF statement.

View 5 RepliesI am sending an email with an attachment using the following Code
Dim msg As New System.Net.Mail.MailMessage(req.EmailFrom, req.EmailTo)
Dim att As New System.Net.Mail.Attachment("C:Documents and SettingsmichaelrDesktop1216259.pdf")
With msg
.Attachments.Add(att)
[code]....
The file size of the attachment is 396KB, upon the recipient receiving the email outlook shows the file size as 543Kb. Strange thing is if I send an email with the same attachment using outlook the file size is 396Kb.I understand that file sizes can increase due to the attachment being base 64 encoded as opposed to just raw binary.What I am failing to see is why outlook send a file which is 396KB in size but in code when sending it, the same file is 543Kb.
how would i implement a way that i would not hard code the email message that the application send to email recipients? how will i also include email message formatting (text in bold, italic, etc.)?

(before the smtp.Send, of course)
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 am buidling an application that users can use to submit text data and attachments to email recipients. Certain fields, quite a few in fact from the textboxes in the app will be in the email body, and some in the subject line.This is how I am doing it right now, but I figured there has to be a better way. In VB it is one single line of code, not many like it is here. Ideally I would like to be able to better control the positioning in the message body.
mail.Body = String.Concat(Label1.Text, " ", TextBox1.Text, " ", Label2.Text, " ", TextBox3.Text, " ", Label5.Text, " ", DateTimePicker1.Text, " ", Label3.Text, " ", TextBox2.Text, " ", Label6.Text, " ", RichTextBox1.Text, " ", Label7, " ", RichTextBox2.Text)
