I would like to know if there is any way to use PDFNet sdk in
languages other that .NET,
I mean I would like to buy PDFNet SDK and use it in Delphi 5.0 and VB6
programming languages but as I noticed from your web site you have
only mentioned about .NET application.
Besides .NET version, PDFNet SDK (www.pdftron.com/net) is also
available as a cross-platform C/C++ library.
Although we do not directly support VB6 at the moment, it is possible
to wrap PDFNet related functionality in a form of a stand-alone C DLL
or an ActiveX component which can be accessed from VB6, Delphi 5, etc.
In this case, you would implement the core PDF functionality using
PDFNet for C++ and expose your glue functions as a simple C or ActiveX
In the near future, we are also planning to release a 'pure C' DLL and
wrapper around the entire API for more direct access from VB6, Delphi
5, Java, etc.
