- 13. Introduction The names of the Orchid .Net Classes correspond to the module types: • LvxLive - the Live module • LvxRt - the real-time Primary module (based on Basic Sequencer DRAL) • LvxRtAr - the real-time Asynchronous Reset module (based on Asynchronous Reset Sequencer DRAL) • LvxPrep - the Preprocessor module • LvxDX - the DirectX Processor module • LvxDll - auxiliary class for controlling the load of Orchid.DLL. Its properties and methods are static, i.e. you do not need to create an instance of this class and use the properties and methods directly. • LvxException - class for throwing exceptions, derived from System::Exception
- 14. • For C/C++ compilers the Orchid.lib import library must be linked to your application and the Orchid.h file must be included. Note that for Borland compilers the OrchidBc.lib must be used instead. • For Borland Delphi , the Orchid.pas unit is to be added to your project and referenced in the "uses" part in other units. Alternatively, you can use OrchidDyn.pas , which can load Orchid DLL on demand. • For MS Visual Basic 6 the Orchid.bas file is to be added to the project.
