EmailMessage Class To Send Email Message(s) From Local Computer
May 18, 2009
I am using the EmailMessage to send email message(s) from my local computer. I am also using the SMTP server of my ISP and generally it works just fine. However, some of the emails are never delivered to the destination (bouncing emails) and i get "Mail Delivery failed: returning message to sender" How do i check if the message can be delivered rather than receive the "returning message to sender"? Should i check the destination email server? I have no idea from where to start actually.
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 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.

I'm writing a program that will scan a barcode from a serial scanner and store the information in a MySQL database.
In the program I would like to check for when the scanner is not working. If it's not working then send me an email. I set a variable called MessageBody which sets the body of the email that is going to be sent. The subroutine is called EmailError(). So I can call it in other subroutines. I would like to take a variable or something and put it in the Message body so I can have a dynamic message body and not a static boring one.
Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click If MessageBox.Show("YOU'RE ABOUT TO SAVE A BID. DO YOU WANT TO CONTINUE?", "G.M.S. | CONFIRM BID", MessageBoxButtons.YesNo) = Windows.Forms.DialogResult.Yes Then MainScreen.lblMessage.Visible = True lblMessage.Visible = True

When I did this on my lap top it was working fine, when I put this project on my work PC it won't send the message.
This is my first time trying to create a windows application that can be used to send an email message. It's a new requirement that we have to satisfy. Our customer information is saved in a database and we needed to send them some advertisement messages to some or all of them.
I created a windows application but unfortunately I couldn't send a single email message.
I tried to modify my code several times with no luck; each time I'm getting a different exception message. I tried to search the wen for more information regarding this issue but I end up with the same result.
I don't know if I must have an smtp server to relay the messages and be able to send them. If this is the case how I can do that? Is it possible to accomplish this with something else.
Dim Message As MailMessage = New MailMessage() Dim Smtp As New SmtpClient() Dim SmtpUser As New System.Net.NetworkCredential()
I have spent at least 6 hours trying to write a program that will send emails to a constant list of email addresses. I was trying to make it so all that I need to type is the subject, body, and "nickname". I wanted to use the same email to send the message every time (yahoo or gmail address), and the recipients to be a constant list of emails.
We have an excel spreadsheet with about 10000 names (company and email address) and we need to send some legal docs to them. I'm looking for a way to automate this either via a macro in excel or templates in outlook.Problem with macro in excel is that the code I was able to findcustomize doesn't let me insert a formatted text in the message body.[code]...

ok here is my problem, im making a little app for school since our school blocks pretty much everything so here is my plan a student makes 2 gmail accounts one for school one at home.
in the program at school (client) they put a site request into a textbox and they hit send, the request is then sent to the home pc gmail account and another app on the other side downloads the full site that they have requested and then sends them an email back with an attachment of the complete website, it is then opened in a browser and they have the site, simple idea and it would be easy except.
my school blocks the smtp protocols in vb, even outlook cant use gmail accounts only the schools registered email, however, you can access gmail on the internet without any blockages and you can send and recieve on the gmail website.so how can i use a webbrowser control to log the user into there gmail account through a custom gui, and send a string like www.facebook.com to the home pc gmail account, and then use the web browser controll on the students laptop to recieve the response email through a web browser, is there some kind of gmail api i can use?
I need to copy a file from a local computer to a remote computer on the network, if i try to use File.Copy without logon i get the following error:"Logon failure: unknown user name or bad password."How do I provide user name and password for file copy?
i have a task to create a TCP Server (a program that is listening on its network card interfaces for incoming data stream).I have search on the internet and i found that i can use two methods : Socket or TCPListener class.I have created an example for Socket class, but i wondering how could i test it? I need to check that if another computer in the network send some string data to the listener computer , then this message should be displayed.Here is the example from microsoft that i am using for TCP Server using Socket:
Public Shared Sub Main() ' Data buffer for incoming data. Dim data = nothingc[code]....
But it does not work because of the PORT setting.If in the TCP Server i have "Dim localEndPoint As New IPEndPoint(ipAddress, 0)" the client crashes, but if i change the port from any (0) to 11000 for example,the client works fine.Do you know why?
Later edit2:Maybe i should have started with this question:Which method is recommended for my scope?asynchronous or synchronous method ?
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)
