We have over 30 PDF forms that have been in production for years. They all use submitForm() to request data from the server.
The server uses this code to return FDF data that subsequentially populates fields in the form.
Dim objFdfDoc As FDFDoc
...
Response.BinaryWrite objFdfDoc.FDFSaveToBuf
But all of a sudden some of our customers clients (IE browsers with Adobe Reader) are not getting any return data. Do you have any idea why?
The problem has been encountered on IE6 and IE7 with AR7 and AR8.
Have you verified that the Server is recieving the Request and returning a response? Some customers may have firewalls that are causing problems.
Is Acrobat displaying an error message?
Have you checked the parameters used in "submitForm"? There are several changes in Acrobat 8 security and may cause "submitForm" to fail. For example "cPassword".
Does the submission URL use a port other than 80? This could also cause a problem with a firewall.
