Dim mailman As New Chilkat.MailMan

// ...
// ...

Dim numBodyLines As Int32
numBodyLines = 5
Dim msgnum As Int32
msgnum = 1

// ------------------------------------------------------------------------
// The FetchSingleHeader method is deprecated:

Dim emailObj As Chilkat.Email
emailObj = mailman.FetchSingleHeader(numBodyLines,msgnum)
If (mailman.LastMethodSuccess = False) Then
    System.DebugLog(mailman.LastErrorText)
    Return
End If

// ...
// ...

// ------------------------------------------------------------------------
// Do the equivalent using FetchOne.
// Your application creates a new, empty Email object which is passed 
// in the last argument and filled upon success.

Dim headerOnly As Boolean
headerOnly = True

Dim emailOut As New Chilkat.Email
Dim success As Boolean
success = mailman.FetchOne(headerOnly,numBodyLines,msgnum,emailOut)
If (success = False) Then
    System.DebugLog(mailman.LastErrorText)

End If
