Thx.
When i use visual studio 2012 and use this instruction: (sorry my english is so bad....)
#import "MSVBVM60.DLL" raw_interfaces_only no_implementation named_guids rename_namespace ("vb6") rename ("EOF", "vbEOF") rename ("RGB", "vbRGB") rename ("GetObject", "vbGetObject")

Generate this file "MSVBVM60.tlh" into this file, this code.

VARIANT * Number );
float __stdcall Rnd(
VARIANT * Number );

How vstudio generate this code? if this function not here???
