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.

I am trying to create a new MailAddress, the email is coming from Request Parameters, that is: Request.Params("fromEmail"). It is actually being sent from an android device through an http request.When I try to create a new MailAddress from this email, I get the error "The specified string is not in the form required for an e-mail address". When trying to create it directly, that it ma=new MailAddress("a@b.com") using the same coming string, it works, but creating it using ma=new MailAddress(Convert.ToString(Request.Params("fromEmail")) produces the error.

I get the following error:Application-defined or object-defined error.From what I can understand, it's when I attempt to attach a file to the email, I get that error. What I noticed is that it's because the file is in use.Is there anyway to attach the file anyway? My users are simply not closing their files after saving, right now I'm using computer manager to kick them out. The process is for them to save a file on a server through a share and then I pick that up and send it. Works fine as long as they close the file after save.

I've implemented with Visual Basic 10 an application for Net Framework 4 with functionality to send files via e-mail using System.Net.Mail. It works well except when it comes to sending an XML file whose name contains accents. In the latter case the UTF-8 name is not correct, so Widows Mail Life presents him with name consisting of a set of meaningless characters. Furthermore, the content has lost the format of lines and spaces, presented part of MIME type information in the header, so that it is unreadable XML readers. However, with a name without accents is sent successfully.[code]....

I had a requirement to gloss up an email generated from bespoke system using 'mailto' to be glossed up. I don't believe I can produce HTML message using mailto so I decided to generate the mail using System.net.Mail.mailMessage. However, as the client wants to add to the email prior to sending it on I need to send it to the client's own email, allow them to edit using their email editor and they would then forward it to the target recipientUnfortunately, the tables on forwarding are reformatted.

Check Email if gmail and valid password length.
Screenshot:
Public Class Form1
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
[Code].....
This code might be useful for validating email address, and for simple email sender/bomber.

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 teaching myself vb.net and wanted to change this code to have an embedded mail.boby from a text file instead of the file attachment. Code spippet below and where I need help is mail.Body = ("tracertALL.txt")
that just puts the name of the file NOT the contents of the file. This code is a CMDWrapper that runs a batch file and I want the contents of a trace route that is pipe to a file >> tracertALL.txt .

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.

Here is the problem, I have an Access form and a textbox for an e-mail address. The email address is not required, I only want to check for a valid email address when a value or address has been entered into the e-mail filed. Example: If e-mail is not empty or if email field has a value, then check for the follow elements, matched the email address with the required format. If the e-mail field is empty, do not look for anything, move on.

I would like to know if there is a simple way to validate an e-mail address? I have seen many ways that appear to use functions but I would like to use something simple because currently my error control is done like this:
If txtEmail.Text = "" Then
ErrorProvider1.SetError(txtEmail, "You must enter your e-mail address.")
Else
ErrorProvider1.SetError(txtEmail, "")
Is there a way to use the same type of syntax but instead of checking if the textbox is empty, check if it a valid e-mail address? I know the regular expressions can be used, but how in this circumstance?
