{{Quickfixn}} IndicationOfInterest - IOIid error

[Grant Birchmeier]

I've never coded in VB, but it's all just classes and methods in either
language.

StringField is just a QF/n class (it's the base class of all string
fields), and given your earlier code, I know you know how to use "new"!

To create a field 23=999 (which is IOIShares or IOIQty, depending on which
FIX version you are on), the code would be:
    new StringField(23, "999")
Similarly, you could also do it as a IntField:
    new IntField(23, 999)
QF/n is smart enough to work it either way.

If you have an IOI message, you can call:
    ioiMsg.setField(new StringField(23, "999"));

(There is no SetString, sorry, my mistake.  )

And the generic getter is:
    ioiMsg.getField(23) // returns field value as a string, e.g. 999

Or you can do:
    f23 = StringField(23);
    ioiMsg.GetField(f23); // sets f23's value to what it finds for 23 in
ioiMsg
    // the above will also work if f23 = *Int*Field(23)

You should definitely have a look at this page:
http://quickfixn.org/tutorial/custom-fields-groups-and-messages.html
The generic methods are touched on at the bottom, but the custom DD stuff
on the page is also very important.
