OK, I have determined that I CAN pass an object to a COM exe. But I am running into a problem operating on the array property of the object.

I want my object that I'm passing to the COM exe to encompass all the arrays that I'm trying to avoid passing as parameters, as properties of the object. This is all fine and dandy, I can reference the object's properties (as arrays) and interrogate the properties one by one. But I cannot manipulate it in the COM exe the same way I can in the calling program.
I cannot do an ALEN() on it. The COM exe craps out there.

Based on the code below, does anyone see something that I may be missing? Why can I NOT do an ALEN inside of a VFP COM exe?


loComObject=CREATEOBJECT("ComPassObject.MyComObject")
loTest = CREATEOBJECT("Custom")
loTest.AddProperty("paCC[3,2]")
loTest.paCC[3,1] = "Hello WOrld"
MESSAGEBOX(loComObject.DoSomething(loTest))

DEFINE CLASS MyComObject AS Session OLEPUBLIC
PROCEDURE DoSomething
LPARAMETERS toArrayOne
LOCAL lnRetVal
** lnRetVal = toArrayOne.paCC[3,1] && this works
lnRetVal = ALEN(toArrayOne.paCC,1) && this doesn't
RETURN lnRetVal
ENDPROC
ENDDEFINE

TIA
Cathy
