(VB.NET UWP/WinRT) IMAP Capability

Demonstrates how to send the CAPABILITY command to request a listing of capabilities that the IMAP server supports. A capability name which begins with "AUTH=" indicates that the server supports that particular authentication mechanism.

Dim imap As New Chilkat.Imap

Dim success As Boolean

'  Anything unlocks the component and begins a fully-functional 30-day trial.
success = imap.UnlockComponent("Anything for 30-day trial")
If (success <> True) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If



'  Use TLS
imap.Ssl = True
imap.Port = 993
success = Await imap.ConnectAsync("MY-IMAP-DOMAIN")
If (success <> True) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


'  Authenticate
success = Await imap.LoginAsync("MY-IMAP-LOGIN","MY-IMAP-PASSWORD")
If (success <> True) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


'  Get the list of capabilities:
Dim caps As String = Await imap.CapabilityAsync()
Debug.WriteLine("Capabilities: " & caps)

'  Here is an example of the string returned:
'  * CAPABILITY IMAP4rev1 UNSELECT IDLE NAMESPACE QUOTA ID XLIST CHILDREN X-GM-EXT-1
'  UIDPLUS COMPRESS=DEFLATE ENABLE MOVE CONDSTORE ESEARCH UTF8=ACCEPT APPENDLIMIT=35882577
'  LIST-EXTENDED LIST-STATUS

'  Chilkat v9.5.0.58 introduces the HasCapability method to
'  check to see if a particular capability exists:
If (imap.HasCapability("QUOTA",caps) = True) Then
    Debug.WriteLine("IMAP server supports the QUOTA extension.")
End If


If (imap.HasCapability("IDLE",caps) = True) Then
    Debug.WriteLine("IMAP server supports IDLE.")
End If



'  Disconnect from the IMAP server.
success = Await imap.DisconnectAsync()
