Dim upload As Chilkat.Upload
Set upload = Chilkat.NewUpload

' Specify the page (ASP, ASP.NET, Perl, Python, Ruby, CGI, etc)
' that will receive and process the HTTPS Upload.
upload.Hostname = "www.mywebserver.com"
upload.Path = "/receiveUpload.aspx"

' Make sure to indicate that TLS is to be used, and the port should be
' 443 rather than 80.
upload.Ssl = True
upload.Port = 443

' Add one or more files to be uploaded.
upload.AddFileReference "file1","dude.gif"
upload.AddFileReference "file2","swordfish.xml"
upload.AddFileReference "file3","sample.doc"

' Do the upload.  The method returns when the upload
' is completed.
' This component also includes asynchronous upload capability,
' which is demonstrated in another example.

success = upload.BlockingUpload()
If (success <> True) Then
    Debug.Print upload.LastErrorText
Else
    Debug.Print "Files uploaded!"
End If
