I am trying to send e-mails with VB.net and I have a template for the code but I don't understand a few lines.[code...]
As far as I understand, mail.From is the sender's name, and mail.to.add is the person I am sending to. What does smtpServer.Credentials do?
I deduce that SmtpServer.Credentials is the only one that requires a password so that will be the account the e-mail will be sent from. But then what is the point of mail.From? What happens if I put different e-mails in credentials and mail.From.
I want to send an automatic E-mail based on the date. If the current date is greater than 5 days than the current date field in the table then i need to send an E-mail to the designated person. I am using VS.NET2003/VB.NET/ASP.NET/SQL Sever 2000.

The main problem is that to send an E-mail from G-mail, you need to use smtp.gmail.com as the host, and the port number 587.
Dim SMTPServer As New SmtpClient
SMTPServer.Host = "smtp.gmail.com"
SMTPServer.Port = 587
SMTPServer.EnableSsl = True
However, for Hotmail, I would need a different Host and Port, smtp.live.com. Other E-mail clients would therefore require more different hosts. Is there a way, to address all of them without listing all possible E-mail host names and ports?
If not, what alternative is there to supporting all the E-mail hosts without throwing an error?

View 6 RepliesI have a software under contruction for a small firm. And it requires email functionality. That is, whenever the users in the main database reaches the payment date, an email will be send to that user as a reminder.Or, in certain period, the admin needs to send a notification mail to all the users in the main database.
So, how can I incorporate that facility in my main app ?My present idea is to create a separate app for send the mails. That is, when the admin compose the mail and selects a bunch of users (as recipients) from the database, all the message will be saved to another database (for mailing application) and will start the mailing app. This mailing app will check it's database for any pending emails to be sent, and if there exists any pending mails, it will start sending one by one. After sending each mail, it will remove that from the database.
What's your idea ? Does it sounds ok to you I don't want the user of my main app to know that there exist another program, running in background, sending emails.
I am using VB.net to send my mails through outlook. Where i am giving the resource path for the pictures inserted in to it.
But Email shows the inline pictures as attachments. what could be the reason?
The important thing is that this is not happening all the time. if we send 5 to 10 times we get the expected result for 2 or 3 times.
i explored some of the forums , got answers like 'changing the settings, security settings of the office outlook. that too is not succeeded.

I am trying to Send an Email with an attachment (using Gmail) but I keep getting errors like "Operation Timed out" or Failure Sending Email".

I need to pass a block of binary data to a web service. The object I'm passing is part of an API, so the Serialize/Deserialize/Byte functions are built-in to the API class. It is not explicitly XML Serializable as far as I can tell.
Unfortunately, whenever I pass the data to my web service, even as an encoded string, the service returns a "(400) Bad Request" error. If I remove the encoded data and replace the variable with a simple string, an appropriate response is returned, ruling out authentication, service errors, etc.
'Convert the byte array into an encoded string'
Dim unicodeEncoder As New UnicodeEncoding()
Dim serializedData As String = unicodeEncoder.GetString(myObject.Bytes).Trim()
Dim webAuth As New myWebService.ServiceSoapClient
MessageBox.Show(webAuth.VerifyFeatureSet(serializedData , "", "", "", ""))
how I can accomplish this? If I need to encode the data a different way, include a snippet for decoding it on the far end.
