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)

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 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 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

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...

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 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.

Is there a 'simple' way to determine the current user's email address ? I want to automatically send an email when an application detects an unhandled exception, but would like it to come from the current user.I found this on the net and haven't yet worked out what its doing (although it seems to work). Unfortunately, as I'm not sure how it works, I also don't know what drawbacks there are to this technique.[code]...

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 was wondering how i would be able to validate a textbox for the E-MAIL address of a person. For example it cant have anything like "`#[]-=+->~| etc. it MUST have an @ and a .com or .co.uk at the end of the e-mail. anyway i was wondering how i would be able to program this when the user types into the textbox they cant put in any of the other symbols?and IF there is a missing @ or .com then the user should receive an error message telling them to make sure that they put them in.how would i program that on a button?

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.

I know, it's a bit weird asking for a query to tell me my own email address right, I'll explain further...
I'm writing a COM add-in for Outlook 2007. One of the subs generates and sends an email to a particular address and this all works fine.However I have a need to have an option for the sender to be able to include themselves on the recipients list.As more than one person will be running this I cannot just set the sender's email address manually and would prefer to just add a check box on the form to enable this feature.
The only bit I'm stuck on is working out how to find the email address of the person sending the email. I could do it with an AD query against the logged on user but this needs to work for non-domain users also so need another method.

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 trying to get my program to send very simple text email messages. I did do a search beforehand, and found that I was having the same issue as someone else, but the specific question I have was not answered --
I've learned that if you're trying to send mail, you need an SMTP server... I found this list here but every one of them I've tried yields the same "Failure sending mail" error.
Here's my
Dim mail As New MailMessage()
mail.From = New MailAddress("me@mycompany.com")
mail.To.Add("destination-email@whatever.com")
[CODE]...
Is the problem that I need to show "credentials" (i.e. user/pass)? If so, what would those credentials be? Can I use my yahoo email SMTP server with my login info to do it? And is this all I'd need to add to add the credentials?
smtp.Credentials = New NetworkCredential("MyUsername", "MyPassword")
(before the smtp.Send, of course)

Does anybody know if it is possible to download email messages and send something to the email server to delete an email from the server using ASP.NET?
I have developed a program to download email information from my email server, but I can't figure out how to send something to the server to delete an email. I developed what I have using the resources at this location[url]...
I am sick and tired of all the junk mail I am getting and want to write my own program to delete emails from my email server based on criteria I create.
I have VB 3.0, VS 6.0, VS.NET 2003, VS.NET 2005, VS.NET 2008 and VS.NET 2010 Express. I have developed web sites and standalone programs using VB and ASP.NET. My experience and knowledge is not extensive, but i do have enough knowledge to create a VB program.

I have a win form with three textboxes that lets the user input information using VB.net 2008. I am wanting the program to send me the information entered (when they hit the send button) as an email and also drop the information entered into an access database.I have the program sending the textbox information as an email.What I am having trouble with is saving the three textboxes to access database. I have an access database set up with a table and three fields for the three textboxes.
All I need to do is each time a user uses the program, it adds the information they enter into the three textboxes to the three different fields in the database. I don't need to let the user view or edit the database in any way.

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)
