I have an array as a property of an object. The object is passed from a COM dll. I create an object to hold the passed object using:

PUBLIC loQuestion AS comdll.TRQuestionClass

now loQuestion has two properties:

1) Question - type = 'C', value = 'Question 1'
2) Answers - type = 'Z', value = 'Array'

What is a type of 'Z' ? that shows in VFP in the debugger.

The passed object is an arg of variant type. One of it's properties is a collection that contains a string and an array in each item. The questions collection property in the passed arg matches the loQuestion object I created. So it should be the same (2 properties that match my loQuestion object) and it does. It has:

arg.callscript.scriptmodules.item(0).questions.item[0]

Now that object (questions.item[0] in the scriptmodules collection) returns:

TYPE("arg.callscript.scriptmodules.item(0).questions.item[0]") = "O"  && <-- correct

The above is a single question object in the questions collection with an array of matching answers that matches my loQuestion object.
There should be:

arg.callscript.scriptmodules.item(0).questions.item[0].question  && character
arg.callscript.scriptmodules.item[0].questions.item[0].answers  && array

The answers array exists because:

TYPE("arg.callscript.scriptmodules.item(0).questions.item[0].answers") = "A"  && correct, answers is the array I need
ALEN(arg.callscript.scriptmodules.item(0).questions.item[0].answers,1) = 1    && correct there is one element in the array

However, if I try to copy the array over to loquestion.answers, it bombs:

=ACOPY(arg.callscript.scriptmodules.item(0).questions.item[0].answers,loQuestion.Answers) && bombs with 'Feature is not available' msg

and:

FOR it = 1 TO ALEN(arg.callscript.scriptmodules.item(0).questions.item[0].answers,1) -1
  ? it            && prints 0 which is correct - one element in the array
ENDFOR

However,

FOR it = 1 TO ALEN(arg.callscript.scriptmodules.item(0).questions.item[0].answers,1) -1
  ? arg.callscript.scriptmodules.item(0).questions.item[0].answers[it]   && BOMBS!   Returns OLE Error: 'Invalid number of parameters'
ENDFOR

So I cannot step throught the elements to copy it to the loQuestion.Answers array either.

Same error if I just:

 ? arg.callscript.scriptmodules.item(0).questions.item[0].answers[0]   && BOMBS!   Returns OLE Error: 'Invalid number of parameters'

I know it's an array, but passed property seems to be an array I cannot access the elements of and in vfp the object type I create to hold it it is of type 'Z' with a value of 'Array'

In the .net dll it's defined as:

TRQuestionClass

public string[] Answers {get;set;}
public string Question {get;set;]


How do I work with that? I don't understand why the array can't be accessed.

I am working with lots of passed objects in other events and collections and strings all work fine, but arrays seem to be a problem for some reason.
