(VB.NET UWP/WinRT) Asynchronous HTTP Upload
Demonstrates how to do an HTTP upload asynchronously in a background thread.
A server-side C# example showing how to receive an upload is located at C# ASP.NET Code to Receive Upload
Dim upload As New Chilkat.Upload ' Specify the page (ASP, ASP.NET, Perl, Python, Ruby, CGI, etc) ' that will process the HTTP Upload. upload.Hostname = "www.mywebserver.com" upload.Path = "/receiveUpload.aspx" ' Add one or more files to be uploaded. upload.AddFileReference("file1","dude.gif") upload.AddFileReference("file2","pigs.xml") upload.AddFileReference("file3","sample.doc") ' Begin the HTTP upload in a background thread: Dim success As Boolean = upload.BeginUpload() If (success <> True) Then Debug.WriteLine(upload.LastErrorText) Else Debug.WriteLine("Upload started...") End If ' Wait for the upload to finish. ' Print the progress as we wait... While (upload.UploadInProgress = True) ' We can abort the upload at any point by calling: ' upload.AbortUpload(); ' Display the percentage complete and the number of bytes uploaded so far.. ' The total upload size will become set after the upload begins: Debug.WriteLine(upload.PercentUploaded & "% " & upload.NumBytesSent & "/" & upload.TotalUploadSize) ' Sleep 2/10ths of a second. upload.SleepMs(200) End While ' Did the upload succeed? If (upload.UploadSuccess = True) Then Debug.WriteLine("Files uploaded!") Else Debug.WriteLine(upload.LastErrorText) End If
