To use AddEmail in your ASP.NET / VB project perform the following steps:
1. Add a reference to the AddEmail library: In Visual Studio main menu, select View -> Solution Explorer to open Solution Explorer. Right-click on the project that will use AddEmail and select Add Reference from the pop-up menu. Click COM tab, find and select AddEmail 3.0 Type Library, click Select button then OK button.
2. Declare variable that will hold a reference to the SmtpMail object:
Dim objSmtpMail As AddEmailLib.SmtpMailClass
3a. Create an instance of the SmtpMail object:
objSmtpMail = New AddEmailLib.SmtpMailClass()
3b. If you are sending e-mails asynchronously you will need to access the same SmtpMail object on more than one page. In this case store an instance of the SmtpMail object in Session collection:
If IsNothing(Session("SmtpMail")) Then
objSmtpMail = New AddEmailLib.SmtpMailClass()
Session("SmtpMail") = objSmtpMail
Else
objSmtpMail = Session("SmtpMail")
End If 4. Set SMTP server address, port, username and password:
objSmtpMail.SmtpServer = "mail.myserver.com"
objSmtpMail.SmtpPort = 25
objSmtpMail.SmtpUsername = "jsmith"
objSmtpMail.SmtpPassword = "mypassword"
5a. Send an e-mail synchronously using SimpleSend or SimpleSendAttachment:
Dim strError As String Dim resultCode As Integer
resultCode = objSmtpMail.SimpleSend("jsmith@myserver.com", "jane@someserver.com;james@someserver.com", "test", "Test message", strError)
If resultCode = 0 Then ' E-mail was sent successfully
Else ' Send failed, strError contains detailed error description
End If
5b. Alternatively, create and fill MailMessage object and send it synchronously using Send or asynchronously using SendAsync:
' Create message and setup subject and body Dim objMessage As New AddEmailLib.MailMessageClass()
objMessage.MessageSubject = "test"
objMessage.MessageBody = "Test message"
' Setup sender Dim objSender As New AddEmailLib.MailAddressClass()
objSender.Address = "jsmith@myserver.com"
objSender.Name = "John Smith"
objMessage.Sender = objSender
' Setup first recipient Dim objRecipient As AddEmailLib.MailAddressClass
objRecipient = New AddEmailLib.MailAddressClass()
objRecipient.Address = "jane@someserver.com"
objRecipient.Name = "Jane Smith"
objMessage.AddRecipient(objRecipient)
' Setup second recipient
objRecipient = New AddEmailLib.MailAddressClass()
objRecipient.Address = "james@someserver.com"
objRecipient.Name = "James Smith"
objMessage.AddRecipient(objRecipient)
' Send prepared message synchronously Dim strError As String Dim resultCode As Integer
resultCode = objSmtpMail.Send(objMessage, True, strError)
If resultCode = 0 Then ' E-mail was sent successfully
Else ' Send failed, strError contains detailed error description
End If
' Alternatively, send prepared message asynchronously 'Dim messageNumber As Integer
'messageNumber = objSmtpMail.SendAsync(objMessage, True)
' Save the message number. It is used to retrieve the status of the message 6. If the message was sent asynchronously use GetStatus to check the status of the message:
Dim messageStatus As AddEmailLib.MailStatus
messageStatus = objSmtpMail.GetStatus(messageNumber)
Select Case messageStatus
Case AddEmailLib.MailStatus.MailStatusQueued
... Case AddEmailLib.MailStatus.MailStatusSending
...
Case AddEmailLib.MailStatus.MailStatusSent
' E-mail was sent successfully Case AddEmailLib.MailStatus.MailStatusFailed
' E-mail wasn't sent Dim errorCode As Integer
errorCode = objSmtpMail.GetErrorCode(messageNumber)
Dim errorDescription As String
errorDescription = objSmtpMail.GetErrorDescription(messageNumber)
Case AddEmailLib.MailStatus.MailStatusCanceled
...
End Select
