When i call object with ALF:
adt = CreateStaticObject("ADLite.AlfaDirect");
ordno = adt.CreateLimitOrder("109970-000", "MICEX_SHR", "LKOH",
Date(), "sample order", "RUR", "B", 1, 2000, Null, Null, Null,
Null, Null, "Y", Null, Null, Null, Null, Null, Null, Null, Null,Null, Null, 10);
if (ordno == 0) {
_TRACE(adt.LastResultMsg);
}
i see in Trace:
Overflow while converting variant of type (Single) into type (Integer) Formulas\Custom\AlfaDirect.afl 15 27 11:17:12.97
It works well if I call CreateLimitObject from JScript or _vbscript_ (
Can I call this function from AFL?
