(Visual FoxPro) 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
LOCAL loUpload LOCAL lnSuccess loUpload = CreateObject('Chilkat_9_5_0.Upload') * Specify the page (ASP, ASP.NET, Perl, Python, Ruby, CGI, etc) * that will process the HTTP Upload. loUpload.Hostname = "www.mywebserver.com" loUpload.Path = "/receiveUpload.aspx" * Add one or more files to be uploaded. loUpload.AddFileReference("file1","dude.gif") loUpload.AddFileReference("file2","pigs.xml") loUpload.AddFileReference("file3","sample.doc") * Begin the HTTP upload in a background thread: lnSuccess = loUpload.BeginUpload() IF (lnSuccess <> 1) THEN ? loUpload.LastErrorText ELSE ? "Upload started..." ENDIF * Wait for the upload to finish. * Print the progress as we wait... DO WHILE (loUpload.UploadInProgress = 1) * 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: ? STR(loUpload.PercentUploaded) + "% " + STR(loUpload.NumBytesSent) + "/" + STR(loUpload.TotalUploadSize) * Sleep 2/10ths of a second. loUpload.SleepMs(200) ENDDO * Did the upload succeed? IF (loUpload.UploadSuccess = 1) THEN ? "Files uploaded!" ELSE ? loUpload.LastErrorText ENDIF RELEASE loUpload
