About exchanging data with PowerBuilder
You
can use the IPB_Session interface or the IPB_Value
and IPB_Arguments interfaces to exchange data between PowerBuilder
and PBNI. The IPB_Session interface contains many virtual
functions that enable the C++ code in an extension
to interact with the PBVM. The IPB_Value and IPB_Arguments
interfaces contain methods that you can use to pass values between
PowerBuilder and extensions.
