* PRG file (to edit with VFP)* Open with VFP as default* Build: none

GUINEU

* Declaration

using VfxGuineuRuntime;private readonly VfxGuineu _fox = new VfxGuineu("<Name>.FXP");

GUINEU

* Function call

_fox.Do("<function name>", <parameter 1>, <parameter 2>, …);

* The first parameter is the function name

* Following parameters are passed to the function

GUINEU

* Passing parameters* Also objects!

* Many VFP functions

* Many VFP commands
