Yes, the file is Reader Extended.
According to Adobe Support, only becuase I am using this command:
event.target.submitForm( {cURL: "http://server/ASPNETWebPage.ASPX", aPackets:["datasets","pdf"], cSubmitAs: "XDP"});
the above command will send the XML Data and the PDF curent state, and the last state of the PDF embedded (before any change). So basically, the PDF size will double with every submit.
I was told, if I send only PDF (without XDP) then only the last PDF state is sent. But then, I have to use another service/process "exportData" to extract the XML Data from the PDF.
I have never used "exportData" from .NET. So, I am now looking for a way to extract only the last stafe of the PDF from the submitted XDP.
Tarek.
