Setting value of a indexed property of an OLE object

Rails
1

I suspect this question is not directly related by Rails but perhaps
Ruby
users on this list know an answer for this

I have an OLE object which has an indexed property on it (something like
a
dictionary).
In C# (or similar languages) I set the value of one of the elements in
the
indexed property such as this

MyOLEObject myObject = new MyOLEObject();
myObject[“property name”] = “property value”;

While using ruby Win32Ole api, if I use square brackets as I use in C#,
I
get the error " Unkown property or method ‘property name’ ".
I suspect this is because ruby Win32Ole api tries to set a real propery
on
the object such as

myObject.property name = “property value” which is not possible.

Can you give me any directions about how to solve this problem, aka
setting
an indexed property through Win32OleApi
