Accessing COM properties that take arguments

[Jim@Abcam]

sorry if this has been covered before, but I have an external COM object which
has properties that require arguments... e.g. to write a property I need to
write script something like

objFoo.Property("argument") = value;

However, doing this causes CF to complain that I'm trying to assign a value to
a function (this is how it parses the statement).

So, how to I write values to COM object's where the properties require
arguments?
