Upload Files to a Web Server - Simplest TLS Example

See more Upload Examples

This is the simplest example for uploading some files to a web server using SSL/TLS. the BlockingUpload call is synchronous and returns when the upload is finished (or failed).

A server-side C# example showing how to receive an upload is located at C# ASP.NET Code to Receive Upload

Dim success As Boolean = False

Dim upload As ChilkatUpload
upload.Initialize("upload")

'  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
    Log(upload.LastErrorText)
Else
    Log("Files uploaded!")
End If
