Validate A Textbox For The EMAIL Address Of A Person?
Jun 12, 2011
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 have a simple textbox with an email address.
I need to know the best and easiest way to find out whether that email address is valid or not. I want to know how I can do that.
I have tried using the below code but it does not display any message for me? Can anyone point the mistake I am making?
Public Function IsValidEmailAddress(ByVal email As String) As Boolean
Try
Dim ma As New MailAddress(email)
[Code].....

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 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'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 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 am still having some issues with the issue I posted last time regardin formview not updating correctly.I have managed to narraow the problem to one sub below:My issue appears to be on this line: tbl.Rows.AddAt(tbl.Rows.Count 1, row)Anytime I attempt to update a row, only the first row gets updated. Subsequent rows don't get updated. Instead, when I click "Update", the cursor moves down to the next record without updating it.When I commented out this tbl.Rows.AddAt(tbl.Rows.Count - 1, row), I can now update each and every row. After updating the row, an email goes out to the individual advising him/her about the update s/he just made. The problem is that email is getting sent to the wrong person and that's because of that one line that I just commented out.

how to code the "from" portion when an email via vb.net. I could easily do "mm.From= email@domain.com"...but for this project it needs to be sent automatically depending on which user is entering the information. So I have lets say a group of 10 users, anytime a specific user sends in an update on a project form, the email is sent to the manager from the person who it's been updated from. Any suggestion? They all have specific ID's. How would I code it to where I could get the program to find them by their ID and then get their email address from their ID?
Protected Sub SendEmail()
Dim ToAddress As String = ConfigurationManager.AppSettings("AstMgr").ToString()
Dim mm As New Net.Mail.MailMessage("Engineering.Systems@exchange.nscorp.com", ToAddress)

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'm having some problems with validating Urls and IP addresses with RegEx.
This regular expression doesn't work properly. For example, it returns True for "www.123.123.123.123" and "http://www.123.123.123.123".
vb.net
Regex.IsMatch(txtTextBox.Text, "(((http|https)://)|(www.))+(([a-zA-Z0-9._-]+.[a-zA-Z]{2,6})|([0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}))")

I'm trying to validate an IP address in dot decimal format e.g. 127.55.21.1
System.Net.IPAddress.TryParse(IP, Nothing)
This though returns numbers like "500" or "9" as valid. Why does it do this? Do I have to set the IP address version, if so how would I do this?
