There's VFP registry class in the registry class library in the FFC subdirectory.

#INCLUDE registry.h
oReg = NEWOBJECT("registry", "registry")
lc_buffer = space(255)
lc_regname = "Excel.Sheet.5\protocol\StdFileEditing\Server"

oReg.GetRegKey("", @lc_buffer, lc_regname, HKEY_CLASSES_ROOT)
? lc_buffer
