Question

以下代码在标记为行的办公室中的两台计算机上使用VB.exe中的“未处理的异常故障”杀死VB6（sp6）。

''# 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

从我在各种网站上可以看出，我正确地传递了一个数组，但我实际上是否正确地做了，为什么它会导致VB6死得如此可怕？

Answer 1

我没有答案，当然是一个奇怪的问题，但为什么不只是添加方法并继续前进？

'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

Answer 2

这是MS中从未修复过的错误（已编译好）。我正在使用像这样的临时数组的解决方法：

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

    tempArray = newArray
    oClass.myArray = tempArray <- Should work now
    MsgBox "passed"

End Function

仅供参考，当您不小心将鼠标悬停在param或数组属性上时，Byte数组（长数组是安全的）会变得更糟。最好让你的鼠标远离代码： - ））

我不知道为什么会这样，但如果你想要一个数组的副本，请在class2中使用Variant：

Private m_myArray As Variant

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

Friend Property Let myArray(anArray As Variant)
    m_myArray = anArray
End Property

修复它，但我仍然对这个原因感到好奇。

在VB6中将数组作为参数传递
