hello, i've got a visual basic 5 programs seems it uses 3 functions to make serial, look what i got with smartcheck

__vbavarmul
-lhs (variant)
|-signed long.Lval = 658448104 0x273F1EE8 // 658448104 = my input
-rhs (variant)
|-double.dbval = 2.8678

then next instruction is

__vbavarsub

unsigned long pvar 6681540 0x0065F3C4
unsigned long lpsrc 6681444 0x0065F364
unsigned long argc 7007268 0x006AEC24

then __vbavarint
number(variant)
|-double.dbval = 1887750985 that is the serial

can anyone help me, i need to know whats being multiplied, my input with what ? i think my input * something = the values that are in __vbavarsub but dunno witch one of them

Tnx in advance

OLE Automation use a common structure named VARIANT to process most kinds of variables. VB functions(such as __vbavarsub, __vbavarmul) also use this structure to pass parameters. The following declaration is cut from <oaidl.h> from VC++.
