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 am trying to use System.Web.Mail (using this example url...) to send email bit the Import is failing. The Imports knows of System.Web but there is no .Email.

Every time when I try to send emails to external Email ids using SMTPClient, it is failing (not sending and no error message). However, when I try to send Emails to my internal staff, it is working fine. I cant find the reason why it is not sending to External Contacts. All of these external contacts have been added in the Exchange serber 2010 Mail contacts.[code]...
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'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.
Is there any possible way to send e-mail using VB.net on an Windows XP Home operating system? having to work around the IIS issue by jeopardizing my computer. I've looked around a lot and just can't figure it out for myself.
I'm working on an application that will send an email at a certian point.I'm using System.Net.Mail and it works fine when I do a "Debug - Start Debugging". But when I build the application, and run it, it crashes the whole thing when it gets to the client.Send(message) part.[code]

I have the following piece of code that contains my message body in an email I'm trying to send via vb.net (through outlook) The code works, but .net is not recognizing the HTML formatting and is giving the error: "XML literals and XML axis properties are not available Please Add references to the System.Xml.dll, System.Xml.Linq.dll, and System.Core.dll assemblies". I try and do this by going to Project --> add referance, but they are not highlighted and I can't select them. Is there any way around this?
I am a one man dev shop and need some outside opinions on how to approach this project.
I need to create a "post office" program that will send html emails thru the system.net.mail framework.
For each job submitted to the postoffice the app would need to read a user created html email string from the database, read a string of email addresses to send to and send out the emails based on a set processing time.
The first step would be to parse out the email addresses to find out how many emails it needs to send out and determine how many it would need to send per minute to complete the job in 20 minutes tops. I.e. if 1000 email addresses are submitted per job it would determine that it needs to send 50 emails per minute to complete the job.
The part I am stuck on is how I should queue the emails. If the app determines it needs to send 50 a minute should I only load up the first 50 on a timer event then get the next 50 queued up for the next timer tick? Or would it be better to load up all 1000 in a loop and build in some kind of wait time after it sends the first 50?
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 with an attachment using the following Code
Dim msg As New System.Net.Mail.MailMessage(req.EmailFrom, req.EmailTo) Dim att As New System.Net.Mail.Attachment("C:Documents and SettingsmichaelrDesktop1216259.pdf") With msg .Attachments.Add(att)
[code]....
The file size of the attachment is 396KB, upon the recipient receiving the email outlook shows the file size as 543Kb. Strange thing is if I send an email with the same attachment using outlook the file size is 396Kb.I understand that file sizes can increase due to the attachment being base 64 encoded as opposed to just raw binary.What I am failing to see is why outlook send a file which is 396KB in size but in code when sending it, the same file is 543Kb.
how would i implement a way that i would not hard code the email message that the application send to email recipients? how will i also include email message formatting (text in bold, italic, etc.)?
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)
I wouuld like to open outlook with new email with provided subject line, body message and attachment but no email address. User will enter the email address and click send . How can I do this?

i can send email through vb.net behind code but how do i implement so that the recipient cannot see the sender email and only the name?i had done alot of research but i can't find any solution about this problem
Are there any good books out there that will show someone how to set up a form using Visual basic that will take information and send it to the server and then send a recipient an Email?

make an app for me that just sends an email of text from a textbox. if u have a source to one or anything like that because i have tried over and over and it just doesnt work
I want to send an email using the default email client. If this is not possible, then Outlook will be the client of choice.* I want to be able to send attachments.* I would like to use Read Receipt on outgoing emails if possible.
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...
