Email Validation - Create Program - Asks The User Type His/her Email Address Into A Textbox

Feb 9, 2009

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)

Email Address Validation With RegEx?

Mar 7, 2012

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.

Form Validation - Correctly Formatted Email Address?

May 5, 2011

I have a txt box that askes a user to enter his email address and I want to make sure the user enters a correctly formatted email.

The code I have so far is like this
If txtEmail.Text = "" Then
txtEmail.BackColor = Color.Pink
MessageBox.Show("Please Enter your Email")
Exit Sub
Else
txtEmail.BackColor = Color.White
End If

How I can modify this code to make it work and is regular expressions the same for all programming languages? Also for my mobile number text box I only want a user to enter a 10 digit number with only integer numbers.

The code I have so far is
If txtNumber.Text = "" Then
txtNumber.BackColor = Color.Pink
MessageBox.Show("Please Enter your Mobile")
Exit Sub
Else
txtNumber.BackColor = Color.White
End If

Regex Email Address Validation Fails If Underscore Character Present

Aug 31, 2010

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...

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.

Asp.net - Check That Email Address Is Valid For System.Net.Mail.MailAddress?

Aug 11, 2011

Currently, to avoid errors from being thrown up due to invalid email addresses, I do the following:

Dim mailAddress As MailAddress
Try
mailAddress = New MailAddress("testing@invalid@email.com")
Catch ex As Exception
'Invalid email
End Try

However, rather than depending on Try..Catch, is there a way of validating that the email address will be 100% valid for the MailAddress type?I know there a plenty of regex functions out there for validating emails, but I'm looking for the function which the MailAddress type uses to validate its addresses.

Get Outlook Email Address Not In A Group

Jun 22, 2010

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.

Mailing DataGrid To Email Address

Apr 7, 2010

I decided to have a go with Visual Studio 2010 using the VB language. Basically, aI have a windows form which shows a datagridview. The datagridview is filtered when the user selects a combo box. I then want the user to be able to e-mail the datagrid to a e-mail address. I've had a good look around the internet and found a way of sending the datagrid by HTML format. This has a few problems though - it doesn't look quite right (the columns aren't broken up by any lines) and the information isn't filtered (it sends everything that is stored it the datagrid).

Here is my code so far.
Dim oApp As Outlook._Application
oApp = New Outlook.Application
Dim oMsg As Outlook.MailItem
oMsg = oApp.CreateItem(Outlook.OlItemType.olMailItem)
[Code] .....

Here is what the form looks like when filtered.
Here is what the e-mail looks like.
So my question is, how do I get a filtered datagrid e-mailed?

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.

Validate Email Address On Exchange Server?

I'm allowing users to manage a distribution list stored in a database. Users are only allowed to enter emails that are @mydomain.com.

To send an email I'm using this code:

Dim SentFrom As String = "me@mydomain.com"
Dim MessageBody As String = "blah blah blah"
