The sample demonstrates retrieving e-mail while staying responsive to user actions. User can abort e-mail downloading process by closing the app.
Note: This sample code is for Visual Basic only. ASP does not support events.
By default, MailBee does not processes Windows events when performing mail operation. This gives maximum performance and fits fine for web applications (such as ASP ones).
Desktop applications, however, usually give user an option to interact with the app even when it is busy (e.g. receives e-mail).
To let MailBee process Windows events, EnableEvents property of POP3 object must be set to True before connecting to POP3 server.
MailBee is also capable of firing its own events (such as download progress). See EnableEvents property documentation for details.
' Declare mailer object global to control
' it within different subroutines
' User clicked the button. Must get e-mail
Private Sub Command1_Click()
' Allow POP3 object to process Windows
' events during operation

' Unlock POP3 component
objPOP3.LicenseKey = "put your license key here"
' Set POP3 server name
objPOP3.ServerName = "mail.server.com"
' Set user credentials
objPOP3.UserName = "username"
objPOP3.Password = "password"
' Connect to the server and log in the mailbox
If objPOP3.Connect Then
' Completely download all messages in
' the mailbox (this often takes some time)

' do not get any e-mail yet

' User closed the app

' If e-mail is still being received,
