The code to merge FDF and PDF works fine is a Window Application but in Web application i most of the time get an error on saving the merged file saying "External Component has thrown the exception".
I have given rights(Internet Guest Account and ASPNET) to the folder where i am merging and saving the final File. But still sometime it generates and most of the time it Fails to save.
Also till my application is running, the Merged/saved PDF always remain Locked. To open that PDF i have to stop the application completely. I tried using EndSave, Dispose , Close properties but still i cant open the file till my application stops completely though i can make a copy of that at run time. I even terminated the PDF Creator Library. But still no success.
