Passing arrays as parameters in VB6

Question

The following code kills VB6 (sp6) with an 'unhandled exception fault in VB.exe' on two machines in the office on the line marked.

''# Form1.frm
Option Explicit
Private ArrayHolder As Class2

Private Sub Command1_Click()
    Set ArrayHolder = New Class2

    Dim arr(3) As Long
    arr(0) = 1
    arr(1) = 2
    arr(2) = 3

    ArrayHolder.Add arr

End Sub

''# -----------------------------------------------------------    
''# Class1.cls
Option Explicit

Private m_myArray() As Long

Public Property Get myArray() As Long()
    myArray = m_myArray
End Property

Friend Property Let myArray(ByRef anArray() As Long)
    m_myArray = anArray
End Property

''# -----------------------------------------------------------    
''# Class2.cls
Option Explicit

Friend Function Add(newArray() As Long) As Class1
    Dim oClass As Class1
    Set oClass = New Class1

    oClass.myArray = newArray  <- This kills VB6 dead
    MsgBox "passed"

End Function

From what I can tell on various websites I am passing an array correctly but am I actually doing it correctly, and why is it causing VB6 to die so horribly?

Answer 1

I don't have an answer, and certainly is a curious question, but why don't just add a method and move on?

'Passed the test
Public Sub LetMyArray(anArray() As Long)
    m_myArray = anArray
End Sub


'oClass.MyArray = newArray ' <- This kills VB6 dead
oClass.LetMyArray newArray  ' <- This works
