VB编程：利用指针实现数组拆分-44

Private Declare Sub CopyMemory Lib "kernel32" Alias "RtlMoveMemory" (Destination As Any, Source As Any, ByVal Length As Long)

Private Sub Form_Load()

    Dim arr()

    arr = Array(1, 2, 3, 4, 5, 6, 7, 8, 9)

    Text1.Text = ""

    For i = 0 To UBound(arr)

        Text1.Text = Text1.Text & arr(i)

    Next i

    Dim str(4)

    CopyMemory ByVal VarPtr(str(0)), ByVal VarPtr(arr(4)), 5 * 16 '截取数组标号第四位之后的数

    ReDim Preserve arr(UBound(arr) - 5)

    Text2.Text = ""

    For i = 0 To UBound(arr)

        Text2.Text = Text2 & arr(i) '显示前半截

    Next i

    Text3.Text = ""

    For i = 0 To UBound(str)

        Text3.Text = Text3 & str(i) '显示后半截

    Next i

End Sub
