Is there any way that you can implement a version check in the form so that non-adobe PDF readers are rejected?
For example, A client opened up a form in Apples Preview, was able to fill it all in but when it came to "submit via email" the button did nothing. I tested this myself and came to the same conclusion, but i used the Adobe PDF viewer for mac and everything worked fine.
Any help would be Appreciated.
You can use the app.viewerType command that will return to you a string to indicate which viewer is looking at your file. Not sure what will happen in another Viewer but the doc says:
Reader will be returned for Acrobat Reader version 5 or greater
Exchange will be returned for Adobe Acrobat earlier than version 6.0
Exchange-Pro for Acrobat Pro version 6 or later
Hope that helps
