Dim http As New Chilkat.Http()

Dim success As Boolean

'  Any string unlocks the component for the 1st 30-days.
success = http.UnlockComponent("Anything for 30-day trial")
If (success <> true) Then
    MsgBox(http.LastErrorText)
    Exit Sub
End If


'  Set the login/password for HTTP NTLM Authentication:
http.Login = "myLogin"
http.Password = "myPassword"
http.LoginDomain = "myLoginDomain"
'  Negotiate authentication allows the HTTP client
'  to dynamically select either Kerberos or NTLM, depending
'  on what the server supports.
http.NegotiateAuth = true

'  Download a .zip from chilkatsoft.com:
'  PS> This download URL doesn't actually require
'  authentication.  You'll want to replace this URL with your own.
success = http.Download("http://www.chilkatsoft.com/preRelease/ChilkatDotNet2.zip","ChilkatDotNet2.zip")
If (success <> true) Then
    MsgBox(http.LastErrorText)
Else
    MsgBox("Download Complete!")
