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

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
