I'm using asp.net & vb.net in Visual Studio 2005 & IE6. I have a web application that uses the FileUpload component to choose a file on the hard disk, process the file, and then return a message in the Label to indicate that the process is done. When I made it an AJAX project, this working program failed with the error message "Object reference not set to an instance of an object" (only the label is in the UpdatePanel). I have attached a Word document, which I think should outline the problem, but please let me know if there is more I need to provide.
Thank you for your help.
