I know you can use regex to verify an email address format, but is there a way to, outside of sending an email to the address to verify that an email address is actually a working email address?

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)

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.

I am sending an email using VS2010 VB which works fine, except I would like to have the recipient see their name in lieu of their email address upon receiving the email. I've tried different 'To' addresses, ([URL]), but nothing seems to work. It always shows the email address when received.

I have a form1 that logs in the user to my hotmail/live email sender. In form1 I have 2 textboxes. First ask for email address for live/hotmail and the other ask for the password. Then it takes you to form2 (email sender). My problem is if the user enters a wrong password or email the program still takes them to form2... hence the program wont work if they try to send an email.. Is there a way I can verify if at form1 that the email and password is correct before it moves on the form2?

i have my program all working, but i need to pass an additional piece of information and noticed that when you are in the debug mode and you expand the email address there is a DisplayName when you break down User and Host in the To field
Example Code
emailAddress = "someone@dreamincode.net"
Name = "Joe Someone"
MailMessage.to.add(emailAddress)

I am working on a web form that instead of having the user enter their email address, I would like to be able to retrieve that information and assign it to a variable. So everything remains transparent. So basically what I am asking is. Whether or not vb.net has a class that allows you to get the users email.

I am trying to verify that I have a valid subnet mask. I have already verified that the string format 255.255.255.0 or whatever 255.255.240.0 converts to a UInt32 but now I need to make sure its actually a subnet mask.
The bits should be split between 1's for the network part and 0's for the host part. It should start with all 1's and end in all 0's if it goes from 1's to 0's then finds any more 1's its an invalid subnet mask.

I'm adding an email facility to my VS2008 (VB) project. I have the form and most of the code in place but am unsure about adding the detail to the textboxes. My data will come from an Sql datatable via a Stored Procedure. What I would like to do is use the autocomplete property of the recipients textbox so as to show the Display Name and the Email Address as is done in Outlook. Like John Smith <jsmith@*****>

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.
