})

Remarks

You can use this event to stop the upload if the currently uploaded file fails some server-side verification. To do this, you can use the following algorithm:

1. Configure ActiveX/Java Uploader to send every file in a separate package, i.e. set the FilesPerPackage property to 1.

2. Write your server-side upload script. It should apply some verification to the uploaded file and put the corresponded string value to the response. For example, "Success" if the file meets verification conditions or "Failed" if does not.

   C#

   <script runat="server">
   void Page_Load()
   {
   	if (Request.Files.Count == 0)
   		return;
   	
   	if (VerifyFile(Request.Files[0]))
   		Response.Write("Success");
   	else
   		Response.Write("Failed");
   }
   </script>

3. Then use the AfterPackageUpload event handler to check this response using the response parameter. If it equals to "Failed" the event handler should return false.

   JavaScript

   function afterPackageUpload(index, response){
   	if (response.substring(0, 6) == "Failed")
   		return false;
   	else
   		return true;
   } 

4. Right now the upload process stops and the Error event is fired with error code 18.
