I don't understand why the application cannot accept pdf file or bmp file created by a scanner? It stopped at the "postData = Request.BinaryRead(Request.TotalBytes)" in commonfunctions file with illegal operation. Please advise. Chris.
It's difficult to tell you what's happening without seeing actual files. Please publish your project on Demo Account and send to support@xlinesoft.com a URL to your pages along with instructions on reproducing this error.
I'll find what's wrong with your project inspecting it at Demo account site.
