>>>>>To do what you want with fields no SDK is needed. Acrobat SDK does not offer much more then you already have with a full version of the product. SDK in mainly for C++ developers who are developing Add-ons for Acrobat. In fact, Automation between VB (VFP) and Acrobat is limited comparing to what you can do using SDK (and C++). Remember, you cannot run Acrobat on the Web server to modify PDFs to send them out to client's browser.

The code segment you gave me (which I tested and works great) stops short of how to actually start getting the data out of a PDF. Any further direction you could give me?
