Unsupported and unimplemented PBInvoke features

[ Home / PBInvoke library ]


Unsupported usage of PBInvoke

The following modes may (or may not) work but are not supported officially.
  • Using PBInvoke with PowerBuilder 5 (PBInvoke supports only PB 6 and above)
  • Machine code targets (DLL builds)
  • Web and .Net targets (WinForm, WebForm, JSP, Web services ...)

    Only P-code (PBD) builds are supported.

    Unimplemented features

    The following features will be implemented in one of the future versions of PBInvoke.
  • .Net interop (calls to external .Net classes, not under .Net targets)
  • Java interop (calls to external Java classes)
  • Calls via function pointers (now only named DLL functions and PB callbacks can be called)
  • Double, float as a return type for callbacks. However pointers to such types are supported as a return type.
  • Any struct of size of more than 4 bytes as a return type for any function. However pointers to such structures are supported as a return type.
  • C++ classes, structures inherited from other structures.
